From 80d0198b739660305da17e12072578b7a99cb777 Mon Sep 17 00:00:00 2001 From: Richard Sandiford Date: Wed, 20 Dec 2017 12:54:55 +0000 Subject: [PATCH] poly_int: ipa_parm_adjustment This patch changes the type of ipa_parm_adjustment::offset from HOST_WIDE_INT to poly_int64 and updates uses accordingly. 2017-12-20 Richard Sandiford Alan Hayward David Sherwood gcc/ * ipa-param-manipulation.h (ipa_parm_adjustment::offset): Change from HOST_WIDE_INT to poly_int64_pod. * ipa-param-manipulation.c (ipa_modify_call_arguments): Track polynomail parameter offsets.
