<pre>Checked altivec.h and both of the __builtin and __builtin_altivec_ forms are
there. The function in the example given: __builtin_crypto_vcipher has been
part of altivec.h since 2015. It looks like LLVM does have all of the PPC
crypto functions available for use.
A quick test with this example:
$ cat builtins-ppc-crypto-vcipher.c
#include <altivec.h>
#define D_INIT1 { 0x0102030405060708, \
0x090A0B0C0D0E0F10 };
#define D_INIT2 { 0x7172737475767778, \
0x797A7B7C7D7E7F70 };
// <2 x i64> test_vcipher_e
vector unsigned long long test_vcipher_e(void)
{
vector unsigned long long a = D_INIT1
vector unsigned long long b = D_INIT2
return __builtin_crypto_vcipher(a, b);
}
$ clang -c builtins-ppc-crypto-vcipher.c
$ echo $?
0
Looks like __builtin_crypto_vcipher is working.
There is a passing test case that is part of LLVM that tests all of the PPC
crypto builtins: ./tools/clang/test/CodeGen/builtins-ppc-crypto.c
I see that you are using xlC to compile instead of LLVM. This may be an xlC
only issue.</pre>
