Raising simple arm binary err about llvm-mctoll HOT 7 OPEN

I am confused with the table, is the 'X' means pass or somthing?

from llvm-mctoll.

questions for help:

1. How to fix the arm32 binary raising problem?

2. Is llvm-mctoll  not support thumb instructions yet?

Thanks for your interest in the project.

Support for Thumb instructions is not yet implemented. In general, we plan to bring the functionality to raise ARM binaries on par with at least the current state of raising x86-64 binaries in the near future. Any help is highly appreciated.

I am confused with the table, is the 'X' means pass or somthing?

It means that the functionality is implemented and supported.

@bharadwajy thank you for help for the questions

I met another problem with arm binary


mul instruction can not be decoded.

Are the some success demos for arm binary？I will be grateful if you provide some

from llvm-mctoll.

There are test cases for Arm32 in the test directory:
https://github.com/microsoft/llvm-mctoll/tree/master/test

The warning about failing to decode an instruction is a problem with the LLVM disassembler which mctoll uses to generate the MCInsts. It’s not a problem with mctoll but certainly makes it less useful.

If you are able to fix that I’m sure the LLVM Arm community would be grateful.

Thank you for help

1. about the mul decode error about arm binary , it will not come out when build in armv7 architecture.
2. but there still problem in raising arm , I saw the source code of ARMMachineInstructionRasier.cpp:raiseMachineFunction(), it seems do not raise the mcinsts to bitcode in the function, and always return 1. I think i can not get binary function bit code because of that, and the raising for arm still unuseable for me.
   I want to confirm that is arm raising supportment is work?

this is what i got , which missing define of function should have

; ModuleID = 'main_proj'
source_filename = "main_proj"

declare void @_start_main()

declare void @__atexit_handler_wrapper(i32)

declare i32 @atexit(i32)

declare i32 @test(i32, i32, i32)

declare i32 @main()

Take a look at the changes for Arm we just pushed.
