9bd0dc83 - [CostModel][X86] Improve v8i32 MUL costs on AVX1 targets to account for slower btver2

Sat, 22 May 2021 10:11:38 +0000

[CostModel][X86] Improve v8i32 MUL costs on AVX1 targets to account for slower btver2BTVER2 has a 2 cycle throughput for v4i32 multiplies (same as SSE41 targets), which is only partially hidden by the subvector extracts/insert when splitting v8i32.

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/Analysis/CostModel/X86/vectorized-loop.ll
