From 711e0acdbb2645f5a8aa89014488c24e89ccb0f7 Mon Sep 17 00:00:00 2001 From: Richard Biener Date: Fri, 16 Dec 2022 09:25:40 +0100 Subject: [PATCH] middle-end/108086 - more operand scanner reduction in inlining There's another round of redundant operand scanning in remap_gimple_stmt. The following removes this and also improves one special-case to call a cheaper inline function. PR middle-end/108086 * tree-inline.cc (remap_gimple_stmt): Add stmts to the sequence without updating them.
