-Subject: [PATCH] Pass unpromoted argument to promote_function_mode
-
-This patch updates setup_incoming_promotions in combine.c to match what
-is actually passed in assign_parm_setup_reg in function.c.
-
-Backported from mainline:
-
-gcc/
-
- PR rtl-optimization/64037
- * combine.c (setup_incoming_promotions): Pass the argument
- before any promotions happen to promote_function_mode.
-
-gcc/testsuite/
-
- PR rtl-optimization/64037
- * g++.dg/pr64037.C: New test.
