Set incoming stack boundary to 128 for 64-bit targets
For 64-bit targets, the incoming stack of interrupt handler is aligned to 16 bytes. Update ix86_minimum_incoming_stack_boundary to set the incoming stack boundary of interrupt handler to 128 for 64-bit targets. gcc/ 2017-03-06 Julia Koval <julia.koval@intel.com> PR target/79793 * config/i386/i386.c (ix86_minimum_incoming_stack_boundary): Set incoming stack boundary to 128 for 64-bit targets. gcc/testsuite/ 2017-03-06 Julia Koval <julia.koval@intel.com> PR target/79793 * gcc.target/i386/interrupt-12.c: Update scan-assembler-times directives. * gcc.target/i386/interrupt-13.c: Ditto. * gcc.target/i386/interrupt-14.c: Ditto. * gcc.target/i386/interrupt-15.c: Ditto.
