From 25fcaff409f5c4c6da08f148ffb9404a71e8e4a7 Mon Sep 17 00:00:00 2001 From: Dan Gohman Date: Sat, 5 Jun 2010 00:33:07 +0000 Subject: LSR needs to remember inserted instructions even in postinc mode, because there could be multiple subexpressions within a single expansion which require insert point adjustment.
