[PATCH] D53906: [ELF] Allow configuring the TLS layout for an Android executable

[Ryan Prichard via Phabricator via llvm-commits]

rprichard added a comment.

FWIW: I've published a draft of a document summarizing ELF TLS with emphasis on issues affecting Bionic. It's at https://android.googlesource.com/platform/bionic/+/master/docs/elf-tls.md. These sections are relevant to this LLVM patch:

- https://android.googlesource.com/platform/bionic/+/master/docs/elf-tls.md#Thread_Specific-Memory-Layout
- https://android.googlesource.com/platform/bionic/+/master/docs/elf-tls.md#Bionic-Memory-Layout-Conflicts-with-Common-TLS-Layout

The second link lists several ways of addressing problems with the standard TLS layout on Android. It ought to list the current proposal here (minimum TLS alignment on ARM), but I forgot to add it.
