[LLVMdev] Failure to compile llvm-gcc-4.2-2.7 on FreeBSD on sparc machine
llvm itself compiles fine. gcc frontend has the error, see below. I applied the attached patch, since the name of architecture on FreeBSD is sparc64, not sparc. There is also one more replacement sparc -> spaarc64 was made in gcc/Makefile in llvm-gcc.

In LLVM sense "sparc" means "sparc with ILP32 architecture model", llvm does not support anything 64 bit in sparc world.> size <integer_cst 0x41a08b70 type <integer_type 0x41a1a0b0 bit_size_type> > constant invariant 64> > unit size <integer_cst 0x41a08ba0 type <integer_type 0x41a1a000 long > unsigned int> constant invariant 8> > align 64 symtab 0 alias set -1 > pointer_to_this <pointer_type 0x41a2cbb0>> > LLVM: i8* (32 bits) > LLVM type size doesn't match GCC typeIndeed, LLVM assumes that pointer size is 32 bits (since it's 32 bit sparc), but gcc - definitely not. -- With best regards, Anton Korobeynikov Faculty of Mathematics and Mechanics, Saint Petersburg State University

> So LLVM support for sparc64 has to be implemented I guess.Yes.> Is this work started?I am not aware about any significant sparc-related works during past few years. So, the answer is most probably "no". -- With best regards, Anton Korobeynikov Faculty of Mathematics and Mechanics, Saint Petersburg State University

And SparcInstrInfo.td seems to contain some of the V9-only instructions. Are you sure 64-bit sparc isn't supported at all? Yuri
