--- Comment #10 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by H.J. Lu <[email protected]>: https://gcc.gnu.org/g:b06b1ea150558cfe83111b48b94b4297cb3dec05 commit r17-2918-gb06b1ea150558cfe83111b48b94b4297cb3dec05 Author: H.J. Lu <[email protected]> Date: Sat Aug 1 06:07:43 2026 +0800 x86: Check DECL_INCOMING_RTL for argument passing check For argument declaration, its DECL_INCOMING_RTL holds an RTL for the stack slot or register where the data was actually passed. If an argument's DECL_INCOMING_RTL is a memory operand, it is passed on stack by caller. Change ix86_argument_passed_on_stack_p to return true if the argument's DECL_INCOMING_RTL is a memory operand. gcc/ PR target/126320 PR target/126450 PR target/126529 * config/i386/i386.cc (ix86_spill_register_argument_p): Removed. (ix86_argument_passed_on_stack_p): Remove the second argument. Return true if the argument's DECL_INCOMING_RTL is a memory operand. (ix86_update_stack_alignment): Updated. gcc/testsuite/ PR target/126320 PR target/126450 PR target/126529 * gcc.target/i386/pr126529-1.c: New test. * gcc.target/i386/pr126529-2.c: Likewise. * gcc.target/i386/pr126529-3.c: Likewise. * gcc.target/i386/pr126529-4.c: Likewise.
