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/atomics-indexed.ll | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'llvm/test/CodeGen/PowerPC/atomics-indexed.ll') diff --git a/llvm/test/CodeGen/PowerPC/atomics-indexed.ll b/llvm/test/CodeGen/PowerPC/atomics-indexed.ll index cfe15f0061c..48781471f1d 100644 --- a/llvm/test/CodeGen/PowerPC/atomics-indexed.ll +++ b/llvm/test/CodeGen/PowerPC/atomics-indexed.ll @@ -1,7 +1,7 @@ -; RUN: llc < %s -mtriple=powerpc-apple-darwin -march=ppc32 -verify-machineinstrs | FileCheck %s --check-prefix=CHECK --check-prefix=PPC32 +; RUN: llc < %s -mtriple=powerpc-apple-darwin -verify-machineinstrs | FileCheck %s --check-prefix=CHECK --check-prefix=PPC32 ; FIXME: -verify-machineinstrs currently fail on ppc64 (mismatched register/instruction). ; This is already checked for in Atomics-64.ll -; RUN: llc < %s -mtriple=powerpc-apple-darwin -march=ppc64 | FileCheck %s --check-prefix=CHECK --check-prefix=PPC64 +; RUN: llc < %s -mtriple=powerpc64-apple-darwin | FileCheck %s --check-prefix=CHECK --check-prefix=PPC64 ; In this file, we check that atomic load/store can make use of the indexed ; versions of the instructions. -- cgit v1.2.3
