* [PowerPC][NFC] Avoid checking non-relevant .cfi instructionsJinsong Ji2019-08-301-5/+1
| | | | | | | | | | | | | | | | | | | | | | | | Summary: This is brought up in https://reviews.llvm.org/D64662?id=209923#inline-599490 CFI information are non-relevant to quite some testcases, we should get rid of checking them when its unecessary. This patch avoid generating cfi info in testcases that are not testing prolog/epilog or exception handling.

| | | | | | | | | | | | | | | | As part of the unification of the debug format and the MIR format, print MBB references as '%bb.5'. The MIR printer prints the IR name of a MBB only for block definitions. * find . \( -name "*.mir" -o -name "*.cpp" -o -name "*.h" -o -name "*.ll" \) -type f -print0 | xargs -0 sed -i '' -E 's/BB#" << ([a-zA-Z0-9_]+)->getNumber\(\)/" << printMBBReference(*\1)/g' * find . \( -name "*.mir" -o -name "*.cpp" -o -name "*.h" -o -name "*.ll" \) -type f -print0 | xargs -0 sed -i '' -E 's/BB#" << ([a-zA-Z0-9_]+)\.getNumber\(\)/" << printMBBReference(\1)/g' * find . \( -name "*.txt" -o -name "*.s" -o -name "*.mir" -o -name "*.cpp" -o -name "*.h" -o -name "*.ll" \) -type f -print0 | xargs -0 sed -i '' -E 's/BB#([0-9]+)/%bb.\1/g' * grep -nr 'BB#' and fix Differential Revision: https://reviews.llvm.org/D40422 llvm-svn: 319665
* [PowerPC] Recommit r314244 with refactoring and off by defaultNemanja Ivanovic2017-11-301-3/+2
| | | | | | | | | | | | | | | This re-commits everything that was pulled in r314244. The transformation is off by default (patch to enable it to follow). The code is refactored to have a single entry-point and provide fine-grained control over patterns that it selects. This patch also fixes the bugs in the original code. Everything that failed with the original patch has been re-tested with this patch (with the transformation turned on). So the patch to turn this on is soon to follow.

* [PowerPC] Reverting sequence of patches for elimination of comparison ↵Nemanja Ivanovic2017-09-261-0/+1
| | | | | | | | | | | | | | | | | | | | | | instructions In the past while, I've committed a number of patches in the PowerPC back end aimed at eliminating comparison instructions. However, this causes some failures in proprietary source and these issues are not observed in SPEC or any open source packages I've been able to run. As a result, I'm pulling the entire series and will refactor it to: - Have a single entry point for easy control - Have fine-grained control over which patterns we transform A side-effect of this is that test cases for these patches (and modified by them) are XFAIL-ed. This is a temporary measure as it is counter-productive to remove/modify these test cases and then have to modify them again when the refactored patch is recommitted. The failure will be investigated in parallel to the refactoring effort and the recommit will either have a fix for it or will leave this transformation off by default until the problem is resolved. llvm-svn: 314244
* [PowerPC] Eliminate compares - add i32 sext/zext handling for SETULT/SETUGTNemanja Ivanovic2017-09-231-0/+52
As mentioned in https://reviews.llvm.org/D33718, this simply adds another pattern to the compare elimination sequence and is committed without a differential revision. llvm-svn: 314062
