================
Comment at: clang/lib/Basic/Targets/Sparc.cpp:160-164
+ // Linux doesn't need these variants, but the BSDs do.
+ if (getTriple().getOS() != llvm::Triple::Linux) {
+ Builder.defineMacro("__sparcv9");
+ Builder.defineMacro("__sparcv9__");
+ }
----------------
This is wrong, they should never be defined on any OS for 32-bit SPARC; see https://github.com/gcc-mirror/gcc/blob/master/gcc/config/sparc/netbsd-elf.h#L22 for example (FreeBSD only ever had a 64-bit port so isn't interesting to look at). That is, the contents of this `if` should just be deleted, leaving just `__sparc_v9__`.
================
Comment at: clang/lib/Basic/Targets/Sparc.cpp:246-256
+ if (getTriple().getOS() == llvm::Triple::Linux) {
Builder.defineMacro("__sparc_v9__");
- Builder.defineMacro("__sparcv9__");
+ } else {
+ Builder.defineMacro("__sparcv9");
+ // Solaris doesn't need these variants, but the BSDs do.
+ if (getTriple().getOS() != llvm::Triple::Solaris) {
+ Builder.defineMacro("__sparc64__");
----------------
This doesn't need changing, we can define more things than GCC to keep it simple.
