[llvm] Get rid of "%T" expansions The %T lit expansion expands to a common directory shared between all the tests in the same directory, which is unexpected and unintuitive, and more importantly, it's been a source of subtle race conditions and flaky tests. In https://reviews.llvm.org/D35396, it was agreed that it would be best to simply ban %T and only keep %t, which is unique to each test. When a test needs a temporary directory, it can just create one using mkdir %t. This patch removes %T in llvm.

RuntimeDyldELF: don't create thunk if not needed This patch doesn't create thunk for branch operation when following conditions are met: - Architecture is AArch64 - Relocation target is in the same object file - Relocation target is close enough to be encoded in immediate offset In such case we branch directly to the target instead of branching to thunk Differential revision: https://reviews.llvm.org/D28108 llvm-svn: 291431 2017-01-09 17:56:31 +08:00
