X86: 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. See also the discussion in https://reviews.llvm.org/D35287 llvm-svn: 309774 2017-08-02 08:28:10 +08:00			`; RUN: llc < %s -mtriple=i686-- -mcpu=yonah \| \`
Convert tests using "\| wc -l \| grep ..." to use the count script. llvm-svn: 41097 2007-08-15 21:36:28 +08:00			`; RUN: grep movsd \| count 1`

For PR1319: Remove && from the end of the lines to prevent tests from throwing run lines into the background. Also, clean up places where the same command is run multiple times by using a temporary file. llvm-svn: 36142 2007-04-17 01:36:08 +08:00			`; RUN: grep ucomisd`
