--- Comment #8 from hjl at gcc dot gnu.org <hjl at gcc dot gnu.org> --- Author: hjl Date: Mon Jan 15 16:13:23 2018 New Revision: 256703 URL: https://gcc.gnu.org/viewcvs?rev=256703&root=gcc&view=rev Log: i386: Align stack frame if argument is passed on stack When a function call is removed, it may become a leaf function. But if argument may be passed on stack, we need to align the stack frame when there is no tail call. Tested on Linux/i686 and Linux/x86-64. gcc/ Backport from mainline PR target/83330 * config/i386/i386.c (ix86_function_arg_advance): Set outgoing_args_on_stack to true if there are outgoing arguments on stack. (ix86_function_arg): Likewise. (ix86_compute_frame_layout): Align stack frame if argument is passed on stack. * config/i386/i386.h (machine_function): Add outgoing_args_on_stack. gcc/testsuite/ Backport from mainline PR target/83330 * gcc.target/i386/pr83330.c: New test.
