From 6239665976be7829cb973b4b59f7575d7079058e Mon Sep 17 00:00:00 2001 From: Matthew Malcomson Date: Fri, 15 Nov 2019 12:10:56 +0000 Subject: [mid-end][__RTL] Set global epilogue_completed in skip_pass Set global epilogue_completed when skipping pro_and_epilogue pass When compiling RTL functions marked to start at a pass after the reload pass, `skip_pass` is used to mark the reload pass as having completed since many patterns use the `reload_completed` variable to determine whether to run or not. Here we do the same for the `epilogue_completed` variable and the pro_and_epilogue pass. Also include a testcase that relies on the availability of a define_split in the aarch64 backend that is conditioned on this `epilogue_completed` variable. regtest done on native aarch64 regtest done on native x64_86 gcc/ChangeLog: 2019-11-15 Matthew Malcomson * passes.c (skip_pass): Set epilogue_completed if skipping the pro_and_epilogue pass. gcc/testsuite/ChangeLog: 2019-11-15 Matthew Malcomson * gcc.dg/rtl/aarch64/test-epilogue-set.c: New test.
