Hi, I'm pleased to say that my latest attempt at running test-release.sh finished with minor issues (see below) so I'm planning to provide an big-endian MIPS32r2 pre-built binary in the LLVM 3.5 as an experimental/beta release. I was originally hoping to provide little-endian binaries too but I think there's insufficient time remaining for me to get that ready in time for Phase 1 testing. The minor issues are that 'make check-all' fails tools/c...

Hi, I'm pleased to announce that the MIPS integrated assembler is now good enough to recurse the compiler for MIPS32R2, build a bootable Linux kernel for MIPS32R2, and pass LNT testing for a variety of 32-bit MIPS targets. I've therefore enabled it by default for all 32-bit MIPS targets in both LLVM and Clang. We're not aiming for perfect GAS compatibility but you should find that the commonly used functio...

...ke sure GP doesn't get stomped on? Actually, we generated the list of flags we use without much rhyme or reason, to be honest.

Has anyone converted llvm/projects/test-suite to use the llvm assembler instead of gcc? If so, what was needed to change and how? My assumption is that this would be a good way to test the llvm assembler. Jack -------------- next part -------------- An HTML attachment was scrubbed...

Hi Rafael, There are a lot of flags. Here are the ones you ask about: -KPIC, -call_shared generate SVR4 position independent code -call_nonpic generate non-PIC code that can operate with DSOs -mvxworks-pic generate VxWorks position independent code -non_shared do not generate code that can operate with DSOs -xgot assume a 32 bit GOT Just to make things fun, the SGI notion of cpic (call pic)

...$0,$0' If I compile with -integrated-as it assembles as expected. I was able to get it to work without the integrated assembler with this change: # # extern int unw_getcontext(unw_context_t* thread_state) # # Just trap for the time being. DEFINE_LIBUNWIND_FUNCTION(unw_getcontext) .set mips32r2 teq $0, $0 #elif defined(__ppc__) telling the assembler to allow r2 instructions. Should the integrated assembler be enabled by default for the Mips? It looks as if the stock clang does not use the integrated assembler yet. -Rich
