Thanks for replying!
The reason for the options "-mno-avx -mno-avx2 -mno-bmi2" is that it is
important for us to have a gmp which runs on old intel hardware. And we
had no trouble with those options until this version of clang.
Also, the function in which ld claims to find the out-of-range branch8 is
written in assembly language. However, ld may be lying. There is no
branch instruction in the .asm file, and disassembly of the .o file also
shows no branch instruction.
I will try removing those options and see what happens.
