Thu, 02 Jul 2020 18:15:29 +0000

[NewPM][LSR] Rename strength-reduce -> loop-reduceThe legacy pass was called "loop-reduce".This lowers the number of check-llvm failures under NPM by 83.Reviewed By: ychenDifferential Revision: https://reviews.llvm.org/D82925 List of files: /llvm-project-15.0.7/llvm/test/Transforms/LoopStrengthReduce/ivchain.ll

46a43556 - Make DataLayout Non-Optional in the Module

Wed, 04 Mar 2015 18:43:29 +0000

Make DataLayout Non-Optional in the ModuleSummary:DataLayout keeps the string used for its creation.As a side effect it is no longer needed in the Module.This is "almost" NFC, the string is no longercanonicalized, you can't rely on two "equals" DataLayouthaving the same string returned by getStringRepresentation().Get rid of DataLayoutPass: the DataLayout is in the ModuleThe DataLayout is "per-module", let's enforce this by notduplicating it more than necessary.One more step toward non-optionality of the DataLayout in themodule.Make DataLayout Non-Optional in the ModuleModule->getDataLayout() will never returns nullptr anymore.Reviewers: echristoSubscribers: resistor, llvm-commits, jholewinskiDifferential Revision: http://reviews.llvm.org/D7992From: Mehdi Amini llvm-svn: 231270 List of files: /llvm-project-15.0.7/llvm/test/Transforms/LoopStrengthReduce/ivchain.ll

79e6c749 - [opaque pointer type] Add textual IR support for explicit type parameter to getelementptr instruction

Fri, 27 Feb 2015 19:29:02 +0000

[opaque pointer type] Add textual IR support for explicit type parameter to getelementptr instructionOne of several parallel first steps to remove the target type of pointers,replacing them with a single opaque pointer type.This adds an explicit type parameter to the gep instruction so that when thefirst parameter becomes an opaque pointer type, the type to gep through isstill available to the instructions.* This doesn't modify gep operators, only instructions (operators will be handled separately)* Textual IR changes only. Bitcode (including upgrade) and changing the in-memory representation will be in separate changes.* geps of vectors are transformed as: getelementptr <4 x float*> %x, ... ->getelementptr float, <4 x float*> %x, ... Then, once the opaque pointer type is introduced, this will ultimately look like: getelementptr float, <4 x ptr> %x with the unambiguous interpretation that it is a vector of pointers to float.* address spaces remain on the pointer, not the type: getelementptr float addrspace(1)* %x ->getelementptr float, float addrspace(1)* %x Then, eventually: getelementptr float, ptr addrspace(1) %xImportantly, the massive amount of test case churn has been automated bysame crappy python code. I had to manually update a few test cases thatwouldn't fit the script's model (r228970,r229196,r229197,r229198). Thepython script just massages stdin and writes the result to stdout, Ithen wrapped that in a shell script to handle replacing files, thenusing the usual find+xargs to migrate all the files.update.py:import fileinputimport sysimport reibrep = re.compile(r"(^.*?[^%\w]getelementptr inbounds )(((?:<\d* x )?)(.*?)(| addrspace$\d$) *\*(|>)(?:$| *(?:%|@|null|undef|blockaddress|getelementptr|addrspacecast|bitcast|inttoptr|\[\[[a-zA-Z]|\{\{).*$))")normrep = re.compile( r"(^.*?[^%\w]getelementptr )(((?:<\d* x )?)(.*?)(| addrspace$\d$) *\*(|>)(?:$| *(?:%|@|null|undef|blockaddress|getelementptr|addrspacecast|bitcast|inttoptr|\[\[[a-zA-Z]|\{\{).*$))")def conv(match, line): if not match: return line line = match.groups()[0] if len(match.groups()[5]) == 0: line += match.groups()[2] line += match.groups()[3] line += ", " line += match.groups()[1] line += "\n" return linefor line in sys.stdin: if line.find("getelementptr ") == line.find("getelementptr inbounds"): if line.find("getelementptr inbounds") != line.find("getelementptr inbounds ("): line = conv(re.match(ibrep, line), line) elif line.find("getelementptr ") != line.find("getelementptr ("): line = conv(re.match(normrep, line), line) sys.stdout.write(line)apply.sh:for name in "$@"do python3 `dirname "$0"`/update.py < "$name" > "$name.tmp" && mv "$name.tmp" "$name" rm -f "$name.tmp"doneThe actual commands:From llvm/src:find test/ -name *.ll | xargs ./apply.shFrom llvm/src/tools/clang:find test/ -name *.mm -o -name *.m -o -name *.cpp -o -name *.c | xargs -I '{}' ../../apply.sh "{}"From llvm/src/tools/polly:find test/ -name *.ll | xargs ./apply.shAfter that, check-all (with llvm, clang, clang-tools-extra, lld,compiler-rt, and polly all checked out).The extra 'rm' in the apply.sh script is due to a few files in clang's testsuite using interesting unicode stuff that my python script was throwingexceptions on. None of those files needed to be migrated, so it seemedsufficient to ignore those cases.Reviewers: rafael, dexonsmith, grosserDifferential Revision: http://reviews.llvm.org/D7636llvm-svn: 230786 List of files: /llvm-project-15.0.7/llvm/test/Transforms/LoopStrengthReduce/ivchain.ll
