Bug in raising division instructions.

[deXetrous]

I have been using llvm-mctoll for my project which involves raising of binaries to IR. I have been getting an error when i try to raise binaries which are generated for a C code involving division operation on a variable. It works fine if both the operands are constants.
As an example: The following code snippet works fine.

int main() {
   int a = 4/2;
   return 0;
}

But, there seems to be an issue with variable operands.
As an example:

int main() {
  int a = 10;
  a = a/2;
  return 0;
}

While raising the binary, following error occurs:

*** Generic instruction not raised :   IDIV32r $ecx, <0x557f28d346e8>, implicit-def $eax, implicit-def $edx, implicit-def $eflags, implicit $eax, implicit $edx

Please let me know if this is not implemented or there is an issue from my side.

Thanks for trying the tool and filing the bug report.

Support to raise several x64 instructions still needs to be added - a subset of division instructions are among those. We are actively working towards adding support to missing instructions.

If you have the cycles, we welcome any help you can offer.

Thanks!
