[PATCH] D32354: [ELF] - Set DF_STATIC_TLS flag for i386 target.

[George Rimar via Phabricator via llvm-commits]

grimar created this revision.

This is PR32437.

DF_STATIC_TLS
If set in a shared object or executable, this flag instructs the dynamic linker to reject attempts to load this file dynamically. It indicates that the shared object or executable contains code using a static thread-local storage scheme. Implementations need not support any form of thread-local storage.

Patch checks if IE/LE relocations were used to check if code uses static model. If so it sets the DF_STATIC_TLS flag.
Patch contains testcases for i386 target for now.
