#6 Problem with encoding of instructions

[Anonymous]

I'm not that good with x86 asm, but the following seens
to be a valid statement:

mov edx, dword ptr[esi - 4]

Using the intrinsics equivalent makes Softwire die a
horrible death by throwing INTERNAL_ERROR in
Synthesizer::encodeRegField (Synthesizer.cpp):

mov(edx, dword_ptr[esi - 4]);

Hi, I tested that code and it did not fail on my system. Are
you using the latest release? On what line in
Synthesizer.cpp does the exception get thrown? Thanks.

I'm using winXP, cygwin and gcc 3.4.1 and softwire 4.6.2.

The stack trace is something like this:

Synthesizer::encodeInstruction(const Instruction *instruction)
case EFF_ADDR:
Synthesizer::encodeRegField
last else

I would not count off cygwin weirdness.
