[PATCH] D155544: [AIX][TLS] Add -maix-small-local-exec-tls option.

[Hubert Tong via Phabricator via llvm-commits]

hubert.reinterpretcast added a comment.

Patch should not land before back-end patch. I also suggest having the patch incorporate the new option into the Clang release notes before it lands.



================
Comment at: llvm/lib/Target/PowerPC/PPC.td:324
+                   "Produce a faster access sequence for local-exec TLS "
+                   "variables where the offset from the thread pointer value "
+                   "is encoded as an immediate operand (AIX 64-bit only). "
----------------
As agreed offline:
thread pointer value -> TLS base



================
Comment at: llvm/lib/Target/PowerPC/PPCSubtarget.cpp:127
+
+  if ((!TargetTriple.isOSAIX()) && HasAIXSmallLocalExecTLS)
+    report_fatal_error(
----------------
There should be no confusion over how tightly `!` binds over `&&`.
