--- Comment #16 from hjl at gcc dot gnu.org <hjl at gcc dot gnu.org> --- Author: hjl Date: Tue Jan 26 12:51:07 2016 New Revision: 232825 URL: https://gcc.gnu.org/viewcvs?rev=232825&root=gcc&view=rev Log: Update stack alignment in ix86_update_stack_boundary Stack alignment adjustment for __tls_get_addr should be done in ix86_update_stack_boundary, not ix86_compute_frame_layout. Also there is no need to over-align stack for __tls_get_addr and function with __tls_get_addr call isn't a leaf function. gcc/ PR target/68986 * config/i386/i386.c (ix86_compute_frame_layout): Move stack alignment adjustment to ... (ix86_update_stack_boundary): Here. Don't over-align stack for __tls_get_addr. (ix86_finalize_stack_realign_flags): Use stack_alignment_needed if __tls_get_addr is called. gcc/testsuite/ PR target/68986 * gcc.target/i386/pr68986-1.c: New test. * gcc.target/i386/pr68986-2.c: Likewise. * gcc.target/i386/pr68986-3.c: Likewise.
