--enable-linux --enable-multilib is broken
I'm disabling this in the buildbot for now because I want to get automated failure emails working. This fails during stage2 GCC's install phase with a confusing libtool error that I can't figure out how to squash.
stack pointer not initialized at runtime
Maybe i'm totally wrong here, i'm not that familiar with GCC.
I'm trying to compile a simple c program for a softcore with this toolchain. By viewing the assembly/machine code i've noticed that the stack pointer starts at zero, which is undesired behaviour and makes my program crash.
By examining the default riscv.ld linker script i can see that there is a constant named _gp that is used to initialize the global pointer (gp register) in the default startup code crt0.S. But the stack pointer (sp register) is never initialized.
Did i stumble on a bug? or do i have to do something else to intialize the sp without writing my own startup code?
My toolchain is configured to use newlib and i compile my c code to RV32I machinecode.
std::bad_alloc when allocating a two std::vectors of similar sizes
This following code
#include <vector>
#include <stdint.h>
int main(...) {
std::vector<uint16_t> v0(208 * 156);
std::vector<uint8_t> v1(208 * 156);
return 0;
}
fails

5278be1 Update Linux/RISC-V boot instructions
22094ed Update to privileged architecture version 1.7
fd8e6ae Update riscv-gnu-toolchain to master
I'm assuming this is a libc bug, since odd size combinations trigger it. For example, the following allocations succeed
#include <vector>
#include <stdint.h>
int main(...) {
std::vector<uint16_t> v0(1 << 22);
std::vector<uint8_t> v1(1 << 1);
return 0;
}
#include <vector>
#include <stdint.h>
int main(...) {
std::vector<uint16_t> v0(1 << 1);
std::vector<uint8_t> v1(1 << 22);
return 0;
}
but the following fails
#include <vector>
#include <stdint.h>
int main(...) {
std::vector<uint16_t> v0(1 << 20);
std::vector<uint8_t> v1(1 << 20);
return 0;
}
I have a workaround for the demo.

Unverified downloads in Makefile.in
Hi,
I noticed that the package fetching code in Makefile.in doesn't verify downloads, but immediately pipes them into tar zxf -. This creates an opportunity for man in the middle attacks, where an attacker intercepts the HTTP/FTP connections and modifies the tarballs to contain malicious files.
A simple solution would be to check every package against its known checksum (e.g. SHA256) and abort with an error message on mismatch.

What is going on here? I have my own version of a makefile for all cross-compiling process (download sources, aply patches, build binutils, build gcc with newlib) which at this point is not very clean, but I think that I can share it with anyone that wants to replicate the issue.
By the way I also had to apply the following patch to be able to compile binutils:
sed -i.bak 's_#include <execinfo.h>_/*#include <execinfo.h>*/_' ${BUILD_DIR}/binutils-${VERSION_BINUTILS}/gas/config/tc-riscv.c
Why there's an "#include <execinfo.h>" when none of its implemented functions are used in that file, and the host GCC that I am using does not have that include file?
Thanks,
Nelson

shared libraries crash for at least for 32-Bit Toolchain
Hi,
I managed after some time and patches to run Linux on the RV32 architecture. However, shared libraries don't seem to work. They all crash with the same segmentation fault at the same address.
The same code compiled with --static works without problems.
Several month ago I have tried the 64-Bit toolchain with success.

R_RISCV_COPY relocs and functions

Support for RoCC (Xcustom) by default
I recently updated rocket-chip to master, but the RV toolchain it references (b85637e) no longer supports RoCC (Xcustom) instructions (e.g., custom0) by default. It seems like there may be a temporary fix in there with d836766 (I'm building HEAD to test this now using --with-arch=RV64IMAFDXcustom).
Is there an existing way to enable Xcustom support? Should this be turned on by default? I can't quite tell what the ISA Spec intends regarding the latter question as far as custom0 and custom1 are concerned.
Newlib toolchain: Can't build hello world
I built the Newlib riscv-gnu-toolchain on Ubuntu 14.04 succesfully, but I see linker errors when I try to build the standard helloworld program.

Wrong syntax in usr/include/bits/mathcalls.h ?
Hi,
Trying to compile libvorbis fails with the following errors. Given that it's a file shipped by you I think that it's a problem with the toolchain port, so reporting just in case:

Compiled binaries not working in riscv-qemu
I am not sure if this is a problem with this project, or riscv-qemu, or something else that I am doing wrong.
I have the following test program, compiled with the commands below:
#include <stdio.h>
int main() {
printf("Size of %s: %d\n", "unsigned long long", sizeof(unsigned long long));
printf("Max of %s: %llu\n", "unsigned long long", 18446744073709551615ULL);
}

When executed in qemu, using kernel from the link in "getting started" and the root image with busybox, neither of the binaries work:

(I cross-compiled other complex projects, like 'make', and apparently the compilation went fine. But when I try to execute them inside qemu, the result is the same. At this point is when I went back a step and tried to create the minimal test programs above, which also fail.)
The binaries from the qemu image provided, all of them coming from busybox, work fine:

Am I doing something wrong? Is this something expected at the moment because the ports of the tools are still WIP, so better if I stop playing around with this until the tools are more stable? (I am not sure if these bug reports are useful, or if at this point I am mostly wasting your time).
The repository's sub-title is incorrect (gcc 4.9.2 -> gcc 5.1)
The subtitle to this repository:
GNU toolchain for RISC-V, including GCC 4.9.2
is incorrect and should be updated to GCC 5.1. Neither Scott nor I have write permissions or we'd do it ourselves.
Linker does not produce raw binary files, even though it says it can.
Please see my gist here. https://gist.github.com/sam-falvo/a3aba3db13b382224cfc
After compiling the hw.c program and creating the linker script, nothing I do seems to convince the GNU ld command to produce a real, honest-to-goodness binary file. It always produces an ELF, no matter what.
I'm at a loss on how to proceed from here. This is either a very subtle user-error on my part, or it's a bug in ld.
Here's the help output for ld:
... lots of text elided ...

Any ideas?

RVC: c.bnez not encoded correctly
When compiling code for RV32C, c.bnez instructions are translated incorrectly from RV32. It looks like a simple encoding issue, where a few bits got lost or were shifted. Both the immediate and the involved register is wrong.
Example objdump output (RV32I):
1c000052: 02051463 bnez a0,1c00007a <synch_start>
1c000056 <memory_init>:
[...]
1c00007a <synch_start>:
Corresponding RV32C code:
1c000046: 601a bnez s0,1c00004c <memory_init+0x4>
1c000048 <memory_init>:
[...]
1c00006a <synch_start>:
The objdump output corresponds with the RVC standard, so the problem must be in the RVI -> RVC translation step.
The toolchain's configure --with-arch flag is not symmetric with gcc's --with-arch
Hey guys,
Currently, to build an RV32I toolchain we do:
../configure --with-xlen=32 --with-arch=I --prefix=$RISCV
That's not symmetric with the other --with-arch flags, which expect "--with-arch=RV32I".
Ideally, the toolchain configure would be performed as:
../configure --with-arch=RV32I --prefix=$RISCV
(Conceptually) the "32" would be passed to "--with-xlen", and the entire "RV32I" string would be passed to the other "--with-arch" flags.
Configure is not my forte, so it's not obvious to me how to set the @xlen@ variable based on the @arch@ variable, and whether you can perform that action if the --with-xlen flag was used or not.
Although perhaps we no longer need the --with-xlen flag, in which case XLEN is just ${ARCH:2:2}?
Broken --with-xlen=32 --with-arch=I
The binaries and libraries built with --with-xlen=32 --with-arch=I (git 77f7450, current master) do not seem to match the requested configuration, or each other:
Build script:
git clone https://github.com/riscv/riscv-gnu-toolchain riscv-gnu-toolchain-rv32i
cd riscv-gnu-toolchain-rv32i/
mkdir build; cd build
../configure --with-xlen=32 --with-arch=I --prefix=/opt/riscv32i
make -j$(nproc)
Tests:
$ cat > test.c << EOT
int main() {
return 0;
}

glibc fails to build on Travis CI
Linux gcc doesn't build within travis, error can be seen at line 9078 https://travis-ci.org/riscv/riscv-tools/builds/76549734#L9078
"-msoft-float" flag generates broken binaries when using glibc
I attempted to use riscv64-unknown-linux-gnu-gcc -msoft-float to compile SPECINT (which has a shocking amount of floating point).
The code compiles, but the resulting binaries compute garbage when it comes to floating point. I've been told that glibc does not "support" -msoft-float, so that's suddenly not a surprise.
Question
Is there a way for this combination to noisily complain to prevent users from thinking "my code compiled, thus it should work"? Or should I just wait on a multi-lib implementation of glibc instead?

No libgcc.a for -m32 -march=RV32I
I used to be able to create RV32I binaries that use symbols such as __mulsi3 from libgcc like this:
riscv64-unknown-elf-gcc -c -m32 -march=RV32I -ffreestanding -nostdlib test.c
riscv64-unknown-elf-gcc -m32 -march=RV32I -ffreestanding -nostdlib -o test.elf test.o -lgcc
Here is an example test.c that wants to use __mulsi3:
#include <stdint.h>
void _start(uint32_t a, uint32_t b)
{
uint64_t au = a, bu = b;
int64_t as = (int32_t)a, bs = (int32_t)b;
uint32_t s_mul, s_mulh, s_mulhsu, s_mulhu;
s_mul = a * b;
s_mulh = (as * bs) >> 32;
s_mulhsu = (as * bu) >> 32;
s_mulhu = (au * bu) >> 32;
if (s_mul == s_mulh || s_mulhsu == s_mulhu)
__asm__ volatile ("sbreak");
}
With git head of riscv-gnu-toolchain (1ad4bfc) I can't do that anymore and get the following error:
$ riscv64-unknown-elf-gcc -m32 -march=RV32I -ffreestanding -nostdlib -o test.elf test.o -lgcc

test.o: In function `_start':
test.c:(.text+0x70): undefined reference to `__mulsi3'
collect2: error: ld returned 1 exit status
There used to be a /opt/riscv/lib/gcc/riscv64-unknown-elf/5.2.0/32/libgcc.a, but it's not there anymore. Do I need to build multilib support for this, even when I don't use any libraries but just want full C language support for integer ops? This seems a little bit odd to me..
relocation truncated to fit: R_RISCV_JAL when compiling linux
Hi,
when I compile my kernel (32-Bit toolchain) I get the following error.
LINK vmlinux
LD vmlinux.o
MODPOST vmlinux.o
GEN .version
CHK include/generated/compile.h
UPD include/generated/compile.h
CC init/version.o
LD init/built-in.o
KSYM .tmp_kallsyms1.o
net/built-in.o: In function `netlink_proto_init':
af_netlink.c:(.init.text+0x924): relocation truncated to fit: R_RISCV_JAL against symbol `rhashtable_init' defined in .text section in lib/built-in.o
Makefile:932: recipe for target 'vmlinux' failed
Looks like I hit the 20 bit limit of the instruction. It works when I remove certain features from the kernel.
I get an similar error "unresolvable R_RISCV_PCREL_HI20 relocation against symbol" when I try to compile DirectFB.

adding new opode extensions
at the bottom of riscv-opc.c there is comment
/* Removed const from the following to allow for dynamic extensions to the
built-in instruction set. */
struct riscv_opcode *riscv_opcodes =
(struct riscv_opcode *) riscv_builtin_opcodes;
int bfd_riscv_num_opcodes = RISCV_NUM_OPCODES;
This seems to indicate that there is a [planned] way to easily add instructions. Is there currently a clean way of doing this?
I've currently hacked the riscv_buildin_opcodes data structure to add my extensions, but I would love to know if there is a better way of doing this.
Problem compiling with "make linux" -- "__BYTE_ORDER" is not defined
Compiling with the following command (see issue #3 as for why the CPPFLAGS is necessary):
CPPFLAGS="-Wno-error=unused-value" make linux
leads to the following error (and many more lines like these):
In file included from ../sysdeps/unix/sysv/linux/riscv/sysdep.h:23:0,

#elif __BYTE_ORDER == __BIG_ENDIAN
Using this command fixes the issue, but I do not know if there's a better way to do this. Neither the ./configure nor the Makefile.in seem to hint to any option that might be remotely related to endianness, and the instructions in the main github project page do not mention anything other than the installation path for configure.

Internal error when assembling a jal instruction
When trying to assemble a file containing only the instruction:
jal x0, 0
I obtain the following error:
$ riscv64-unknown-elf-as -o /tmp/test.o /tmp/test.s
/tmp/test.s: Assembler messages:
/tmp/test.s:1: Fatal error: internal Error, line 720, $(RISCV_PATH)/riscv-gnu-toolchain/src/binutils/gas/config/tc-riscv.c
I believe this is the valid instruction because of this line
I'm using a freshly built riscv-gnu-toolchain.
stimecmp removal
Hi,
Before b85637e
stimecmp was recognized. What's the reason of its removal? It breaks the seL4 port build (and the privileged manual). This register is written in seL4 while executing in S-Mode and mtimecmp isn't writeable there. Any suggestions for alternative implementations?
Thanks,
Hesham

At least "riscv64-unknown-linux-gnu-cc" is missing, but "-c++" for example is there. I noticed because it is the one tried to be used by default in a project that I am trying to compile.
Also, a very minor issue -- even if some of them could be just symlinks none of the above are, all of them are "hard copies".
linux-headers/include/asm/ptrace.h out of sync with riscv-linux
It appears linux-headers/include/asm/ptrace.h is out of sync with riscv-linux. Should it be the same as arch/riscv/include/uapi/asm/ptrace.h?
I'm trying to build riscv-strace and need to know which repo to fix.
C++ exceptions
Right now C++ exceptions don't work, the problem seems to be that they cannot be caught at all and so std::terminate gets called for every throw. I was able to track down the commit that breaks it: b85637e

GCC emits some slow integer/float conversions
The following C program
#define defconv(in, out) \
out in ## 2 ## out(in i) { \
union { \
in i; \
out o; \
} conv; \
\
conv.i = i; \
return conv.o; \
}
defconv(long, double)
defconv(double, long)
defconv(int, float)
defconv(float, int)
emits some good int/float conversions, and some bad ones

I think "222r.combine" is the pass that is combining some of these and not others, but I haven't figured out why yet. This is kind of just a note to myself, but if someone wants to look at it then that would be great!

error: initializer element is not constant (building with gcc 4.9.2)
I'm trying to build riscv-gnu-toolchain (commit c85720a) on raspbian jessie. This is my build script:
sudo apt-get install autoconf automake autotools-dev curl libmpc-dev libmpfr-dev \
libgmp-dev gawk build-essential bison flex texinfo gperf
sudo mkdir /opt/riscv32i
sudo chown $USER /opt/riscv32i
git clone https://github.com/riscv/riscv-gnu-toolchain riscv-gnu-toolchain-rv32i
cd riscv-gnu-toolchain-rv32i
mkdir build; cd build
../configure --with-xlen=32 --with-arch=I --prefix=/opt/riscv32i
make
This works fine on Ubuntu 14.04.3 LTS with gcc (Ubuntu 4.8.4-2ubuntu1~14.04) 4.8.4, but on raspbian jessie with gcc (Raspbian 4.9.2-10) 4.9.2 I get the following error:

PIC regression
Commit b85637e breaks position-independent code.
For example, consider the following excerpt from __libc_start_main() in glibc/csu/libc-start.c:
/* Call the initializer of the program, if any. */
#ifdef SHARED
if (__builtin_expect (GLRO(dl_debug_mask) & DL_DEBUG_IMPCALLS, 0))
GLRO(dl_debug_printf) ("\ninitialize program: %s\n\n", argv[0]);
#endifHere is the corresponding disassembly of libc-2.21.so (64-bit version):
/* Call the initializer of the program, if any. */
#ifdef SHARED

#endifNotice that the global variable _dl_debug_mask is being referenced using address 0x1f000 (0x2000044000 at runtime), which is clearly wrong as it points to the text segment. This leads to the branch being incorrectly taken and, shortly thereafter, the indirect dl_debug_printf() call jumping to a nonsensical PC (0xf95ff06f6bc120ee).
For comparison, here is its counterpart from the preceding commit, which has been confirmed to work:

Text and data in the same segement
This isn't a bug per se, but I thought I'd check to see if it was intentional. It looks like the text and data sections get placed into the same ELF segment. On other architectures, the text and data sections typically go into separate ELF segments.

Unnecessary instructions generated for 16/8 bit integer calculations
Consider this code:
int16_t i16_ret(const int16_t *arr, unsigned int arr_len) {
int16_t sum = 0;
for (unsigned int i = 0; i < arr_len; i++) {
sum += arr[i];
}
return sum;
}
The current riscv-gcc with -O3 generates the following:
00000000 <i16_ret>:
0: 02058863 beqz a1,30 <.L4>
4: 00159593 slli a1,a1,0x1
8: 00050793 mv a5,a0
c: 00b505b3 add a1,a0,a1
10: 00000513 li a0,0
00000014 <.L3>:
14: 0007d703 lhu a4,0(a5)
18: 00278793 addi a5,a5,2
1c: 00e50533 add a0,a0,a4
20: 01051513 slli a0,a0,0x10
24: 41055513 srai a0,a0,0x10
28: fef596e3 bne a1,a5,14 <.L3>
2c: 00008067 ret
00000030 <.L4>:
30: 00000513 li a0,0
34: 00008067 ret
Note the slli/srai pair before the branch. It looks like the compiler is trying to truncate the upper 16 bit of the result or sign-extend it. It's not too bad in that case, but being part of the loop hurts performance.
However the compiler does the same even in cases where it wouldn't be needed:
void i16_mem(const int16_t *arr, unsigned int arr_len, int16_t *out) {
int16_t sum = 0;
for (unsigned int i = 0; i < arr_len; i++) {
sum += arr[i];
}
*out = sum;
}
Compiles to (-O3 again):
00000038 <i16_mem>:
38: 02058863 beqz a1,68 <.L10>
3c: 00159593 slli a1,a1,0x1
40: 00b505b3 add a1,a0,a1
44: 00000793 li a5,0
00000048 <.L9>:
48: 00055703 lhu a4,0(a0)
4c: 00250513 addi a0,a0,2
50: 00e787b3 add a5,a5,a4
54: 01079793 slli a5,a5,0x10
58: 4107d793 srai a5,a5,0x10
5c: fea596e3 bne a1,a0,48 <.L9>
00000060 <.L8>:
60: 00f61023 sh a5,0(a2)
64: 00008067 ret
00000068 <.L10>:
68: 00000793 li a5,0
6c: ff5ff06f j 60 <.L8>
Again there's a slli/srai pair. Since the result is stored using a sh, it is not needed though.
When using unsigned ints, the compiler generates a slli/srli pair, but only with -O3. Using -O0 unsigned ints work fine, signed ints still have the problem though.
I also tried with 8 bit integers and got similar results, see below. The problem persists since quite some time, the dumps are from a recent compiler version though (781d50a). Compilers for other targets can optimize this btw., for example or1k llvm/gcc doesn't have this problem.
#include <stdint.h>
// O0: slli/srli lh/lhu/sh

int16_t i16_ret(const int16_t *arr, unsigned int arr_len) {
int16_t sum = 0;
for (unsigned int i = 0; i < arr_len; i++) {
sum += arr[i];
}
return sum;
}
// O0: slli/srli lh/lhu/sh
// O3: slli/srai lhu/sh
void i16_mem(const int16_t *arr, unsigned int arr_len, int16_t *out) {
int16_t sum = 0;
for (unsigned int i = 0; i < arr_len; i++) {
sum += arr[i];
}
*out = sum;
}
// O0: OK lhu/lhu/sh
// O3: slli/srli lhu
uint16_t u16_ret(const uint16_t *arr, unsigned int arr_len) {
uint16_t sum = 0;
for (unsigned int i = 0; i < arr_len; i++) {
sum += arr[i];
}
return sum;
}
// O0: OK lhu/lhu/sh
// O3: slli/srli lhu/sh
void u16_mem(const uint16_t *arr, unsigned int arr_len, uint16_t *out) {
uint16_t sum = 0;
for (unsigned int i = 0; i < arr_len; i++) {
sum += arr[i];
}
*out = sum;
}
// O0: OK lb/lbu/sb
// O3: slli/srai lbu
int8_t i8_ret(const int8_t *arr, unsigned int arr_len) {
int8_t sum = 0;
for (unsigned int i = 0; i < arr_len; i++) {
sum += arr[i];
}
return sum;
}
// O0: OK lbu/lbu/sb
// O3: OK lw/lbu (heavily unrolled, 8 bit additions vectorized)
uint8_t u8_ret(const uint8_t *arr, unsigned int arr_len) {
uint8_t sum = 0;
for (unsigned int i = 0; i < arr_len; i++) {
sum += arr[i];
}
return sum;
}
(bad codegen): Extra shifting with array indexing on RV64
This is a common bad-code generation for RV64, when using an "unsigned int" as an index into an array. This problem does not show up with a signed int index.
int test32ArrayAccess(uint32_t* arr, unsigned int idx) {
return arr[idx];
}
Turns into:
slli a1,a1,0x20
srli a1,a1,0x20
slli a1,a1,0x2
add a0,a0,a1
lw a0,0(a0)
ret
At a minimum, the last two shifts should be combined into a single shift.
signed char gcc bug
Hello,
I've found what I believe to be a bug in the risc-v gcc. As shown in the code below, I define a singed char, however, it is interpreted as unsigned.
void chartest(char *x, char *y) {
if (*x < *y)
printf("c: %hhd < %hhd\n", *x, *y);
else
printf("c: %hhd > %hhd\n", *x, *y);
}
void uchartest(unsigned char *x, unsigned char *y) {
if (*x < *y)
printf("uc: %hhu < %hhu\n", *x, *y);
else
printf("uc: %hhu > %hhu\n", *x, *y);
}
int main(int argc, char **argv) {
{
char a = -1;
char b = 1;
chartest(&a, &b);
}
{
unsigned char a = -1;
unsigned char b = 1;
uchartest(&a, &b);
}
return 0;
}The output of the above code compiled on Ubuntu 14.4 w/ gcc 4.9.2 :
$ ./bugtest-native
c: -1 < 1
uc: 255 > 1
The output when compiled on riscv-gcc and run on spike:
$ spike pk bugtest-spike
c: 255 > 1
uc: 255 > 1
I looked into the assembly produced by riscv-gcc and see that chartest() and uchartest() both treat the arguments as unsigned.

If the compiler had generated "lb" instructions on lines 10140 and 10144 instead of "lbu" I would expect the correct behavior.

pthread_spin_test.c:(.text+0x44): undefined reference to `pthread_spin_destroy'
collect2: error: ld returned 1 exit status
I suspect the implementations are missing in ./glibc/sysdeps/riscv/nptl/pthread_spin_{init,destroy}.c. I worked around this issue by making the stubs call pthread_spin_lock_unlock if __riscv_atomic is defined, but I am not sure if this is correct in all cases.
Build error: ‘TARGET_ALIAS’ undeclared (first use in this function)
I'm trying to build the toolchain, but I keep getting the following error message. I suspect it may have something to do with the version of gcc installed on my system, which is fairly new. I'm using GCC 4.9.2.
