[LLVMdev] Compiling LLVM on SPARC
...ibsupc++/unwind-cxx.h:171: internal compiler
error: Abort
I checked, and the "Offset" variable at this point in the source file
(InstructionCombining.cpp:387), is -23. The offending assert looks like
the following:
// Handle hosts where % returns negative instead of values
[0..TySize).
if (Offset < 0) {
--FirstIdx;
Offset += TySize;
fprintf(stderr, "ERROR: %d", Offset); // << endl;
assert(Offset >= 0);
}
Is anyone able to help me, or have been able to successfully compile
LLVM + LLVM-GCC on the SPARC platform? If so...
