Note that the same (?) instruction is spelled differently in the same file: bc+ 12, 28, L(9) vs. blt+ cr7, L(24) (there is also a mix of using "7" vs "cr7") and llvm is happy with the second form.
I suppose the bc form (which is the generic conditional branch form on PPC) was chosen since there is arithmetic on the branch register bits just before. The meaning of a branch register bit then is not a simple "less than". This is old code, it can surely be improved. Avoiding branch forms which are absent from clang is good, unless we worsen the GMP code quality.
