From 7255d2a8084cb6aa96ea0e5f30acfff76df04ee8 Mon Sep 17 00:00:00 2001 From: Hal Finkel Date: Fri, 8 Jun 2012 19:19:53 +0000 Subject: Enable PPC CTR loop formation by default. Thanks to Jakob's help, this now causes no new test suite failures! Over the entire test suite, this gives an average 1% speedup. The largest speedups are: SingleSource/Benchmarks/Misc/pi - 108% SingleSource/Benchmarks/CoyoteBench/lpbench - 54% MultiSource/Benchmarks/Prolangs-C/unix-smail/unix-smail - 50% SingleSource/Benchmarks/Shootout/ary3 - 32% SingleSource/Benchmarks/Shootout-C++/matrix - 30% The largest slowdowns are: MultiSource/Benchmarks/mediabench/gsm/toast/toast - -30% MultiSource/Benchmarks/Prolangs-C/bison/mybison - -25% MultiSource/Benchmarks/BitBench/uuencode/uuencode - -22% MultiSource/Applications/d/make_dparser - -14% SingleSource/Benchmarks/Shootout-C++/ary - -13% In light of these slowdowns, additional profiling work is obviously needed! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158223 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/CodeGen/PowerPC/ctrloops.ll | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'test/CodeGen/PowerPC/ctrloops.ll') diff --git a/test/CodeGen/PowerPC/ctrloops.ll b/test/CodeGen/PowerPC/ctrloops.ll index ad55fa4a23..f7bd354ce8 100644 --- a/test/CodeGen/PowerPC/ctrloops.ll +++ b/test/CodeGen/PowerPC/ctrloops.ll @@ -1,6 +1,6 @@ target datalayout = "E-p:64:64:64-i1:8:8-i8:8:8-i16:16:16-i32:32:32-i64:64:64-f32:32:32-f64:64:64-v128:128:128-n32:64" target triple = "powerpc64-unknown-freebsd10.0" -; RUN: llc -enable-ppc-ctrloops -enable-ppc-ctrloop-analysis < %s -march=ppc64 | FileCheck %s +; RUN: llc < %s -march=ppc64 | FileCheck %s @a = common global i32 0, align 4 -- cgit v1.2.3-18-g5258
