[PATCH] D60809: [builtins] __gnu_{ldivmod, uldivmod}_helper for libgcc compatibility

[Peter Smith via Phabricator via llvm-commits]

peter.smith added a comment.

Can you update the description to give some context on why these functions are needed in compiler-rt? To the best of my knowledge __gnu_uldivmod_helper is no longer in libgcc and __gnu_ldivmod is only called from the v6-m (cortex-m0) implementation of aeabi_ldivmod in libgcc/config/arm/bpabi-v6m.S which would imply that these functions would not not get called.
