From f238c1844e7bd5c7ea10be53834d6079d3673bc0 Mon Sep 17 00:00:00 2001 From: Tilmann Scheller Date: Fri, 29 Aug 2014 15:04:40 +0000 Subject: [PATCH] [ARM] Add a first test for the Thumb-2 code size optimization pass. While working on a Thumb-2 code size optimization I just realized that we don't have any regression tests for it. So here's a first test case, I plan to increase the coverage over time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@216728 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/CodeGen/ARM/thumb2-size-opt.ll | 12 ++++++++++++ 1 file changed, 12 insertions(+) create mode 100644 test/CodeGen/ARM/thumb2-size-opt.ll diff --git a/test/CodeGen/ARM/thumb2-size-opt.ll b/test/CodeGen/ARM/thumb2-size-opt.ll new file mode 100644 index 00000000000..f98eb924a67 --- /dev/null +++ b/test/CodeGen/ARM/thumb2-size-opt.ll @@ -0,0 +1,12 @@ +; RUN: llc -mtriple=thumbv7-linux-gnueabihf -o - -show-mc-encoding -t2-reduce-limit2=0 %s | FileCheck %s +; RUN: llc -mtriple=thumbv7-linux-gnueabihf -o - -show-mc-encoding %s | FileCheck %s --check-prefix=CHECK-OPT + +define i32 @and(i32 %a, i32 %b) nounwind readnone { +; CHECK-LABEL: and: +; CHECK: and.w r{{[0-9]+}}, r{{[0-9]+}}, r{{[0-9]+}} @ encoding: [{{0x..,0x..,0x..,0x..}}] +; CHECK-OPT: ands r{{[0-9]+}}, r{{[0-9]+}} @ encoding: [{{0x..,0x..}}] +entry: + %and = and i32 %b, %a + ret i32 %and +} + -- 2.34.1
