Hi Andrew- > fatal error: error in backend: SSE2 register return with SSE2 disabled Is this for 32-bit or 64-bit x86? If it's the latter, the ABI demands that the return value in this case is in xmm0 - SSE is required. Alistair

Hi Andrew- > Well -no-sse -mno-mmx works for EFI as it is pre-boot firmware and does not have any floating point C code. We use -no-sse and -mno-mmx code to prevent optimized code gen using these registers for optimizations. Whether it's optimised or not doesn't particularly matter, the x86_64 ABI says that floating-point return values go into SSE registers, so that is where LLVM is

Hi all, I have a sample test case : $ cat 1.c int foo(int x, int y){ int z = x + y; return z/2; } I tried to get its IR form with clang providing subtarget feature as mmx for target x86_64 $ clang -O3 -mmmx 1.c -S -emit-llvm in the IR generated i can see the subtarget-features as function attribute : "target-features"="+mmx" In the SelectionDAG phase in file "X86ISelLowering.cpp", i checked in one of the function what is the subtarget feature by calling few routines o...

I've compiled R from sources on a pentium4 with these falgs: CFLAGS="-march=pentium4 -O2 -pipe -msse -msse2 -mmmx" CXXFLAGS=CFLAGS and on a Celeron (Mendocino) with these: CFLAGS="-march=i686 -O2 -pipe -mmmx" CXXFLAGS=CFLAGS and I've also tried to use both nano and vim as editors. In each case I always get the same error on both computers

Can it be done as follows : $ clang 1.c -mmmx -mno-sse -emit-llvm -S -target i386. My intention is to generate IR for x86 32 bit CPU with MMX feature but without SSE feature and further investigate if vectorization triggers for 32 bit architecture with MMX feature only. Thanks.

Ok, I got a strange case.. I got a bugreport from a user about my application crashing on him. After a bit of trouble, I got him to report back the module and offset it crashed at (win32). I always retain a copy of my symbol files for my release builds, so tracking down the crash address leads to: (gdb) list *0x6d5c2213 0x6d5c2213 is in split_cb_search_shape_sign (cb_search.c:414). 409

Jean-Marc, Are you sure that you don't need to add just -msse to enable the intrinsics rather than a full fledged -march=pentium3? I did some playing around and I can get intrinsics code to compile with -march=i686 -msse on linux with that. Check out:
