...nd therefore might not be noticed by someone who knows. I've noticed that the GNUX32 and GNUEABI/GNUEABIHF environments don't make use of the sincos libcall like the GNU environment does because the guarding condition for this is 'TT.getEnvironment() == Triple::GNU'. The comment in canCombineSinCosLibcall() in LegalizeDAG.cpp suggests that it's intending to use sincos for all GNU environments so I'm wondering whether the exclusion of GNUX32/GNUEABI/GNUEABIHF is deliberate or not. Can anyone confirm? Thanks.
