-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.
