2016-08-10Align thread entry point stackAleksey Vasenev
_beginthreadex does not align the stack on 16-byte boundary as expected by gcc. On x86 targets, the force_align_arg_pointer attribute may be applied to individual function definitions, generating an alternate prologue and epilogue that realigns the run-time stack if necessary. This supports mixing legacy codes that run with a 4-byte aligned stack with modern codes that keep a 16-byte stack for SSE compatibility. https://gcc.gnu.org/onlinedocs/gcc/x86-Function-Attributes.html Change-Id: Ie4e4ab32948c238fa87054d5664189972ca6708e Signed-off-by: Aleksey Vasenev <margtu-fivt@ya.ru>
