[PATCH] D102377: [AIX] Do NOT emit avaiable externally symbols

[Hubert Tong via Phabricator via llvm-commits]

hubert.reinterpretcast requested changes to this revision.
hubert.reinterpretcast added a comment.
This revision now requires changes to proceed.

It is not acceptable on AIX to emit references to symbols without declaring them unless if using `as -u`, which is less desirable than if the `-u` is not needed.

After:

  $ clang -target powerpc-ibm-aix -xc -<<<$'extern inline __attribute__((__gnu_inline__)) void foo() {}\nvoid bar() { foo(); }' -O -Xclang -disable-llvm-passes -S -o - | grep -F foo
          bl .foo

Before:

  bl .foo
  .extern .foo
  .extern foo[DS]
