Subject: AMDGPU: mark {exp,log}10{,f,l} library functions as unavailable
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=49fa89507c3a54c8e0934f46a874d497c3b0c526;p=llvm

AMDGPU: mark {exp,log}10{,f,l} library functions as unavailable

Summary:
The SimplifyLibCalls part of InstCombine generates calls to those otherwise.

I wonder if at some point we shouldn't just call disableAllFunctions() and
then enable functions on a whitelist basis...
