Robin Morisset 30486fa3de [ARM, Fix] Fix emitLeading/TrailingFence on old ARM processors ... Summary: I had only tested this code for ARMv7 and ARMv8. This patch adds several fallback paths if the processor does not support dmb ish: - dmb sy if a cortex-M with support for dmb - mcr p15, #0, r0, c7, c10, #5 for ARMv6 (special instruction equivalent to a DMB) These fallback paths were chosen based on the code for fence seq_cst. Thanks to luqmana for having noticed this bug. Test Plan: Added more cases to atomic-load-store.ll + make check-all Reviewers: jfb, t.p.northover, luqmana Subscribers: aemerson, llvm-commits Differential Revision: http://reviews.llvm.org/D5304 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@217965 91177308-0d34-0410-b5e6-96231b3b80d8		2014-09-17 17:41:16 +00:00
