Run llvm-mctoll occurs error about llvm-mctoll HOT 6 OPEN

Thanks for the additional detail.

I will incorporate fixes for this along with the addition of follow on support that is needed to identify memory accesses and the types of accessed data to abstract them as LLVM variables as appropriate. (Issue #21).

Thanks for reporting the failure. Will look at it.

I have the same issue. The function X86MachineInstructionRaiser::getFunctionReturnType() may push a null pointer on WorkList if it didn't find a proper RetBlock, resulting a dereference of nullptr and crashes the program. However, fixing it by returning nullptr whenever RetBlock not found causes program to abort at X86MachineInstructionRaiser::raiseMachineJumpTable

hi, when I use this tool to raise ls cmd, get core dump.

This is the current problem I have with raising 'ls'.

Assertion failed: (JmpTblBaseCalcMBB.pred_size() == 1) && "Expect a single predecessor during jump table discovery", file d:\llvm-project\llvm\tools\llvm-mctoll\x86\x86jumptables.cpp, line 221

Another problem raising CMOV which is issue #41.
