[PATCH] D98574: [Sparc] Define the same macros for -mcpu=v9 as GCC on Linux

[Brad Smith via Phabricator via cfe-commits]

brad added a comment.

I do not immediately see why the other tests are failing, but at a bare minimum the following test from clang/test/Preprocessor/predefined-arch-macros.c will have to be updated..

  // RUN: %clang -mcpu=v9 -E -dM %s -o - 2>&1 \
  // RUN:     -target sparc-unknown-linux \
  // RUN:   | FileCheck -match-full-lines %s -check-prefix=CHECK_SPARC-V9
  // CHECK_SPARC-V9-NOT: #define __sparcv8 1
  // CHECK_SPARC-V9-NOT: #define __sparcv8__ 1
  // CHECK_SPARC-V9: #define __sparc_v9__ 1
  // CHECK_SPARC-V9: #define __sparcv9 1
  // CHECK_SPARC-V9: #define __sparcv9__ 1
