From 559fb26604c8d3e5bc3f35790cf0885d03dca6a2 Mon Sep 17 00:00:00 2001 From: Nemanja Ivanovic Date: Tue, 26 Sep 2017 20:42:47 +0000 Subject: [PowerPC] Reverting sequence of patches for elimination of comparison instructions In the past while, I've committed a number of patches in the PowerPC back end aimed at eliminating comparison instructions. However, this causes some failures in proprietary source and these issues are not observed in SPEC or any open source packages I've been able to run. As a result, I'm pulling the entire series and will refactor it to: - Have a single entry point for easy control - Have fine-grained control over which patterns we transform A side-effect of this is that test cases for these patches (and modified by them) are XFAIL-ed. This is a temporary measure as it is counter-productive to remove/modify these test cases and then have to modify them again when the refactored patch is recommitted. The failure will be investigated in parallel to the refactoring effort and the recommit will either have a fix for it or will leave this transformation off by default until the problem is resolved. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@314244 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/CodeGen/PowerPC/testComparesllltus.ll | 1 + 1 file changed, 1 insertion(+) (limited to 'test/CodeGen/PowerPC/testComparesllltus.ll') diff --git a/test/CodeGen/PowerPC/testComparesllltus.ll b/test/CodeGen/PowerPC/testComparesllltus.ll index e4006965158..bf3c14f0628 100644 --- a/test/CodeGen/PowerPC/testComparesllltus.ll +++ b/test/CodeGen/PowerPC/testComparesllltus.ll @@ -1,3 +1,4 @@ +; XFAIL: * ; RUN: llc -verify-machineinstrs -mtriple=powerpc64-unknown-linux-gnu -O2 \ ; RUN: -ppc-asm-full-reg-names -mcpu=pwr8 < %s | FileCheck %s \ ; RUN: --implicit-check-not cmpw --implicit-check-not cmpd --implicit-check-not cmpl -- cgit v1.2.3
