H A D | ARMFrameLowering.h | diff 252503 Tue Jul 02 06:13:08 MDT 2013 andrew Work around an ARM EABI issue where clang would sometimes incorrectly align the stack in a leaf function that uses TLS. The issue is, when using TLS, the function is no longer a leaf as it calls __aeabi_read_tp. With statically linked programs this is not an issue as it doesn't make use of the stack, however with dynamically linked applications we enter rtld which does use the stack and makes assumptions about it's alignment. This is only a temporary fix until a better patch can be made and submitted upstream. |
