From e2d2ce9ff1fabe751d3990af4bfa82cbf4998d41 Mon Sep 17 00:00:00 2001 From: Matthias Braun Date: Tue, 1 Aug 2017 22:20:41 +0000 Subject: PowerPC: Do not use llc -march in tests. `llc -march` is problematic because it only switches the target architecture, but leaves the operating system unchanged. This occasionally leads to indeterministic tests because the OS from LLVM_DEFAULT_TARGET_TRIPLE is used. However we can simply always use `llc -mtriple` instead. This changes all the tests to do this to avoid people using -march when they copy and paste parts of tests. This patch: - Removes -march if the .ll file already has a matching `target triple` directive or -mtriple argument. - In all other cases changes -march=ppc32/-march=ppc64 to -mtriple=ppc32--/-mtriple=ppc64-- See also the discussion in https://reviews.llvm.org/D35287 llvm-svn: 309754 --- llvm/test/CodeGen/PowerPC/mem-rr-addr-mode.ll | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'llvm/test/CodeGen/PowerPC/mem-rr-addr-mode.ll') diff --git a/llvm/test/CodeGen/PowerPC/mem-rr-addr-mode.ll b/llvm/test/CodeGen/PowerPC/mem-rr-addr-mode.ll index 26c3cc881b3..e8c12cc36bd 100644 --- a/llvm/test/CodeGen/PowerPC/mem-rr-addr-mode.ll +++ b/llvm/test/CodeGen/PowerPC/mem-rr-addr-mode.ll @@ -1,5 +1,5 @@ -; RUN: llc -verify-machineinstrs < %s -march=ppc32 -mcpu=g5 | grep li.*16 -; RUN: llc -verify-machineinstrs < %s -march=ppc32 -mcpu=g5 | not grep addi +; RUN: llc -verify-machineinstrs < %s -mtriple=ppc32-- -mcpu=g5 | grep li.*16 +; RUN: llc -verify-machineinstrs < %s -mtriple=ppc32-- -mcpu=g5 | not grep addi ; Codegen lvx (R+16) as t = li 16, lvx t,R ; This shares the 16 between the two loads. -- cgit v1.2.3
