I'm trying to compile a Power9 program with Clang 7.0:
$ $HOME/llvm/bin/clang++ -mcpu=power9 -maltivec
TestPrograms/test_ppc_power9.cxx
TestPrograms/test_ppc_power9.cxx:6:11: error: use of undeclared identifier
'__builtin_byte_in_range'
bool x = __builtin_byte_in_range(b, r);
^
1 error generated.
I'm not sure if Clang 7.0 uses another builtin, or if Clang does not
support Power9.
I guess I have one of two questions:
1. What is LLVM's name for __builtin_byte_in_range?
2. Which Clang compilers support Power9?
