The following should work. I've tested it locally by building GCC with both old (2.38 with patch) and new (trunk) Binutils. Ok for trunk? I simply checked as instead of ld. If as supports explicitly relocations, the produced .o file won't be supported by an old ld even if we use -mno-explicit-relocs (because as will generate new relocation types for la.local etc). So such a mismatch between as and ld can be considered "completely broken" and we don't need to support it. And, the Alpha port also check the assembler for the default of -mexplicit- relocs. This should be documented in invoke.texi, but currently it does not mention -mexplicit-relocs for LoongArch at all. So I'll submit the doclater in another patch. -- >8 -- The assembly produced with -mexplicit-relocs is not supported by gas <= 2.39. Check if the assembler supports explicit relocations and set the default accordingly.
Looks good to me.
