[PATCH] D107002: [PowerPC] Implement XL compatibility builtin __addex

[Victor Huang via Phabricator via cfe-commits]

NeHuang added inline comments.


================
Comment at: clang/lib/Sema/SemaChecking.cpp:3426
+  case PPC::BI__builtin_ppc_addex: {
+    if (SemaFeatureCheck(*this, TheCall, "power9-vector",
+                         diag::err_ppc_builtin_only_on_arch, "9") ||
----------------
I think we start using `isa-v30-instructions` for pwr9 only (or later process)  in `SemaFeatureCheck`


================
Comment at: clang/test/CodeGen/builtins-ppc-xlcompat-pwr9-warning.c:4
+// RUN:   -verify %s
+
+extern unsigned long long ull;
----------------
can we also add the run lines for 64 bit LE Linux, 64 bit AIX and 32 bit AIX?  Will also need `#ifdef __PPC64__` for the test case. 


================
Comment at: llvm/test/CodeGen/PowerPC/builtins-ppc-xlcompat-pwr9-64bit.ll:44
+
+define dso_local i64 @call_addex_1(i64 %a, i64 %b) {
+; CHECK-LABEL: call_addex_1:
----------------
This test case is identical as `call_addex_0`  The unsigned long long and signed long long scenarios produce identical IR and we should only keep one test case here.
