* Revert "CodeGen: Allow small copyable blocks to "break" the CFG."Kyle Butt2017-01-111-1/+1
| | | | | | | | | This reverts commit ada6595a526d71df04988eb0a4b4fe84df398ded. This needs a simple probability check because there are some cases where it is not profitable. llvm-svn: 291695
* CodeGen: Allow small copyable blocks to "break" the CFG.Kyle Butt2017-01-101-1/+1
| | | | | | | | | | | When choosing the best successor for a block, ordinarily we would have preferred a block that preserves the CFG unless there is a strong probability the other direction. For small blocks that can be duplicated we now skip that requirement as well. Differential revision: https://reviews.llvm.org/D27742 llvm-svn: 291609
* Tests: Add branch weights to non-layout tests.Kyle Butt2016-07-291-4/+7
| | | | | | | Add branch weights to a few tests that aren't testing layout to make them less sensitive to changes in the layout algorithm. llvm-svn: 277186

* AArch64/ARM64: move ARM64 into AArch64's placeTim Northover2014-05-241-1/+1
| | | | | | | | | | | | | | | This commit starts with a "git mv ARM64 AArch64" and continues out from there, renaming the C++ classes, intrinsics, and other target-local objects for consistency. "ARM64" test directories are also moved, and tests that began their life in ARM64 use an arm64 triple, those from AArch64 use an aarch64 triple. Both should be equivalent though. This finishes the AArch64 merge, and everyone should feel free to continue committing as normal now. llvm-svn: 209577
* AArch64/ARM64: remove AArch64 from tree prior to renaming ARM64.Tim Northover2014-05-241-1/+0
| | | | | | | | | | | | | | | | I'm doing this in two phases for a better "git blame" record. This commit removes the previous AArch64 backend and redirects all functionality to ARM64. It also deduplicates test-lines and removes orphaned AArch64 tests. The next step will be "git mv ARM64 AArch64" and rewire most of the tests. Hopefully LLVM is still functional, though it would be even better if no-one ever had to care because the rename happens straight afterwards. llvm-svn: 209576

* Mass update to CodeGen tests to use CHECK-LABEL for labels corresponding to ↵Stephen Lin2013-07-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | function definitions for more informative error messages. No functionality change and all updated tests passed locally. This update was done with the following bash script: find test/CodeGen -name "*.ll" | \ while read NAME; do echo "$NAME" if ! grep -q "^; *RUN: *llc.*debug" $NAME; then TEMP=`mktemp -t temp` cp $NAME $TEMP sed -n "s/^define [^@]*@\([A-Za-z0-9_]*\)(.*$/\1/p" < $NAME | \ while read FUNC; do sed -i '' "s/;\(.*\)\([A-Za-z0-9_-]*\):\( *\)$FUNC: *\$/;\1\2-LABEL:\3$FUNC:/g" $TEMP done sed -i '' "s/;\(.*\)-LABEL-LABEL:/;\1-LABEL:/" $TEMP sed -i '' "s/;\(.*\)-NEXT-LABEL:/;\1-NEXT:/" $TEMP sed -i '' "s/;\(.*\)-NOT-LABEL:/;\1-NOT:/" $TEMP sed -i '' "s/;\(.*\)-DAG-LABEL:/;\1-DAG:/" $TEMP mv $TEMP $NAME fi done llvm-svn: 186280
* Convert CodeGen/*/*.ll tests to use the new CHECK-LABEL for easier ↵Stephen Lin2013-07-131-1/+1
| | | | | | | | | | debugging. No functionality change and all tests pass after conversion. This was done with the following sed invocation to catch label lines demarking function boundaries: sed -i '' "s/^;\( *\)\([A-Z0-9_]*\):\( *\)test\([A-Za-z0-9_-]*\):\( *\)$/;\1\2-LABEL:\3test\4:\5/g" test/CodeGen/*/*.ll which was written conservatively to avoid false positives rather than false negatives. I scanned through all the changes and everything looks correct. llvm-svn: 186258
* Add explicit triples to AArch64 testsTim Northover2013-02-011-1/+1
| | | | | | | | Only Linux is supported at the moment, and other platforms quickly fault. As a result these tests would fail on non-Linux hosts. It may be worth making the tests more generic again as more platforms are supported. llvm-svn: 174170
* Add AArch64 as an experimental target.Tim Northover2013-01-311-0/+38
This patch adds support for AArch64 (ARM's 64-bit architecture) to LLVM in the "experimental" category. Currently, it won't be built unless requested explicitly. This initial commit should have support for: + Assembly of all scalar (i.e. non-NEON, non-Crypto) instructions (except the late addition CRC instructions). + CodeGen features required for C++03 and C99. + Compilation for the "small" memory model: code+static data < 4GB. + Absolute and position-independent code. + GNU-style (i.e. "__thread") TLS. + Debugging information. The principal omission, currently, is performance tuning. This patch excludes the NEON support also reviewed due to an outbreak of batshit insanity in our legal department. That will be committed soon bringing the changes to precisely what has been approved. Further reviews would be gratefully received. llvm-svn: 174054
