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/Mips/swzero.ll Fri, 27 Feb 2015 19:29:02 +0000 David Blaikie <dblaikie@gmail.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/test/CodeGen/Mips/swzero.ll#4238a89d Don't modify MO while use_iterator is still pointing to it.llvm-svn: 161626 List of files: /llvm-project-15.0.7/llvm/test/CodeGen/Mips/swzero.ll Thu, 09 Aug 2012 22:08:24 +0000 Jakob Stoklund Olesen <stoklund@2pi.dk> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/test/CodeGen/Mips/swzero.ll#63c0e2c5 Fix test cases in test/CodeGen/Mips.llvm-svn: 157868 List of files: /llvm-project-15.0.7/llvm/test/CodeGen/Mips/swzero.ll Sat, 02 Jun 2012 00:05:45 +0000 Akira Hatanaka <ahatanaka@mips.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/test/CodeGen/Mips/swzero.ll#964c891e Fix bug in zero-store peephole pattern reported in pr11615.The patch and test case were originally written by Mans Rullgard.llvm-svn: 147024 List of files: /llvm-project-15.0.7/llvm/test/CodeGen/Mips/swzero.ll Wed, 21 Dec 2011 00:31:10 +0000 Akira Hatanaka <ahatanaka@mips.com>
