[PATCH] D86310: [X86] Align i128 to 16 bytes in x86 datalayouts

[Harald van Dijk via Phabricator via llvm-commits]

hvdijk updated this revision to Diff 540796.
hvdijk retitled this revision from "[X86] Align i128 to 16 bytes in x86-64 datalayout" to "[X86] Align i128 to 16 bytes in x86 datalayouts".
hvdijk added a comment.
Herald added a project: clang.

Rebased on current LLVM. No longer limited to 64 bit mode. 32 bit mode was taken out in D28990 <https://reviews.llvm.org/D28990> because it was not believed to be required for compatibility, but as PR50198 shows, it does cause a compatibility issue to leave that as is.

This diff is uploaded without full context, because full context causes it to grow beyond what Phabricator allows in an upload.

I will write about the current state of compatibility in more detail shortly.
