sfertile created this revision.
sfertile added reviewers: kbarton, nemanjai, amehsan, syzaara, jtony, lei.
sfertile added subscribers: cfe-commits, echristo.
sfertile set the repository for this revision to rL LLVM.
Add support in altivec.h for the following functions, as well as matching
builtins:
vector unsigned long long vec_extract_exp (vector double);
vector unsigned int vec_extract_exp (vector float);
vector unsigned long long vec_extract_sig (vector double)
vector unsigned int vec_extract_sig (vector float)
Add builtins mapping to the vector float/vector double 'test data class'
instructions, as well as a function like macro that will expand to the
equivalent of either:
vector bool int vec_test_data_class (vector float, const int);
vector bool long long vec_test_data_class (vector double, const int);
as well as defines for all the masks used as the second argument to
vec_test_data_class.
