2f448bf5 - [X86] Migrate tests to use opaque pointers (NFC)

Wed, 22 Jun 2022 12:33:12 +0000

[X86] Migrate tests to use opaque pointers (NFC)Test updates were performed using:https://gist.github.com/nikic/98357b71fd67756b0f064c9517b62a34These are only the test updates where the test passed withoutfurther modification (which is almost all of them, as the backendis largely pointer-type agnostic).

6b898beb - X86: Do not use llc -march in tests.

Wed, 02 Aug 2017 00:28:10 +0000

X86: Do not use llc -march in tests.`llc -march` is problematic because it only switches the targetarchitecture, but leaves the operating system unchanged. Thisoccasionally leads to indeterministic tests because the OS fromLLVM_DEFAULT_TARGET_TRIPLE is used.However we can simply always use `llc -mtriple` instead. This changesall the tests to do this to avoid people using -march when they copy andpaste parts of tests.See also the discussion in https://reviews.llvm.org/D35287llvm-svn: 309774 List of files: /llvm-project-15.0.7/llvm/test/CodeGen/X86/isel-optnone.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/CodeGen/X86/isel-optnone.ll

d89125a5 - Teach ISel not to optimize 'optnone' functions (revised).

Fri, 22 Nov 2013 19:11:24 +0000

Teach ISel not to optimize 'optnone' functions (revised).Improvements over r195317:- Set/restore EnableFastISel flag instead of just running FastISel within SelectAllBasicBlocks; the flag is checked in various places, and FastISel won't run properly if those places don't do the right thing.- Test looks for normal ISel versus FastISel behavior, and not something more subtle that doesn't work everywhere.Based on work by Andrea Di Biagio.llvm-svn: 195491 List of files: /llvm-project-15.0.7/llvm/test/CodeGen/X86/isel-optnone.ll
