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 2017-08-02 06:20:41 +08:00			`; RUN: llc -verify-machineinstrs < %s -mtriple=ppc32-- -mcpu=g5`
Added missing support for widening when splitting an unary op (PR3683) and expanding a bit convert (PR3711). In both cases, we extract the valid part of the widen vector and then do the conversion. llvm-svn: 67175 2009-03-18 14:24:04 +08:00
