* [opaque pointer type] Add textual IR support for explicit type parameter to ↵David Blaikie2015-02-271-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | getelementptr instruction One 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 the first parameter becomes an opaque pointer type, the type to gep through is still 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) %x Importantly, the massive amount of test case churn has been automated by same crappy python code. I had to manually update a few test cases that wouldn't fit the script's model (r228970,r229196,r229197,r229198). The python script just massages stdin and writes the result to stdout, I then wrapped that in a shell script to handle replacing files, then using the usual find+xargs to migrate all the files. update.py: import fileinput import sys import re ibrep = 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]|\{\{).*$))") def conv(match, line): if not match: return line line = match.groups()[0] if len(match.groups()[5]) == 0: line += match.groups()[2] line += match.groups()[3] line += ", " line += match.groups()[1] line += "\n" return line for line in sys.stdin: if line.find("getelementptr ") == line.find("getelementptr inbounds"): if line.find("getelementptr inbounds") != line.find("getelementptr inbounds ("): line = conv(re.match(ibrep, line), line) elif line.find("getelementptr ") != line.find("getelementptr ("): line = conv(re.match(normrep, line), line) sys.stdout.write(line) apply.sh: for name in "$@" do python3 `dirname "$0"`/update.py < "$name" > "$name.tmp" && mv "$name.tmp" "$name" rm -f "$name.tmp" done The actual commands: From llvm/src: find test/ -name *.ll | xargs ./apply.sh From 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.sh After 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 test suite using interesting unicode stuff that my python script was throwing exceptions on. None of those files needed to be migrated, so it seemed sufficient to ignore those cases. Reviewers: rafael, dexonsmith, grosser Differential Revision: http://reviews.llvm.org/D7636 llvm-svn: 230786
* R600/SI: Remove M0 from DS assembly stringsTom Stellard2015-02-261-5/+5

* R600/SI: Enable a lot of existing tests for VI (squashed commits)Marek Olsak2015-02-111-37/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a union of these commits: * R600/SI: Enable more tests for VI which need no changes * R600/SI: Enable V_BCNT tests for VI Differences: - v_bcnt_..._e32 -> _e64 - s_load_dword* inline offset is in bytes instead of dwords * R600/SI: Enable all tests for VI which use S_LOAD_DWORD The inline offset is changed from dwords to bytes. * R600/SI: Enable LDS tests for VI Differences: - the s_load_dword inline offset changed from dwords to bytes - the tests checked very little on CI, so they have been fixed to check all instructions that "SI" checked * R600/SI: Enable lshr tests for VI * R600/SI: Fix divrem64 tests - "v_lshl_64" was missing "b" before "64" - added VI-NOT checks * R600/SI: Enable the SI.tid test for VI * R600/SI: Enable the frem test for VI Also, the frem_f64 checking is added for CI-VI. * R600/SI: Add VI tests for rsq.clamped llvm-svn: 228830
* R600/SI: Define a schedule model and enable the generic machine schedulerTom Stellard2015-01-291-3/+3
| | | | | | The schedule model is not complete yet, and could be improved. llvm-svn: 227461
* R600/SI: Add a V_MOV_B64 pseudo instructionTom Stellard2015-01-071-6/+4
| | | | | | | This is used to simplify the SIFoldOperands pass and make it easier to fold immediates. llvm-svn: 225373
* R600/SI: Add a stub GCNTargetMachineTom Stellard2015-01-061-2/+2
| | | | | | | | | | | | This is equivalent to the AMDGPUTargetMachine now, but it is the starting point for separating R600 and GCN functionality into separate targets. It is recommened that users start using the gcn triple for GCN-based GPUs, because using the r600 triple for these GPUs will be deprecated in the future. llvm-svn: 225277
* R600/SI: Change all instruction assembly names to lowercase.Tom Stellard2014-11-051-38/+38

* R600/SI: Use same complex patterns for DS atomicsMatt Arsenault2014-09-051-0/+15
| | | | | | | This fixes hitting the same negative base offset problem that was already fixed for regular loads and stores. llvm-svn: 217256

| | | | | | | | This currently has a noticable effect on the kernel argument loads. LDS and global loads are more problematic, I think because of how copies are currently inserted to ensure that the address is a VGPR. llvm-svn: 214942
* IR: add "cmpxchg weak" variant to support permitted failure.Tim Northover2014-06-131-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds a weak variant of the cmpxchg operation, as described in C++11. A cmpxchg instruction with this modifier is permitted to fail to store, even if the comparison indicated it should. As a result, cmpxchg instructions must return a flag indicating success in addition to their original iN value loaded. Thus, for uniformity *all* cmpxchg instructions now return "{ iN, i1 }". The second flag is 1 when the store succeeded. At the DAG level, a new ATOMIC_CMP_SWAP_WITH_SUCCESS node has been added as the natural representation for the new cmpxchg instructions. It is a strong cmpxchg. By default this gets Expanded to the existing ATOMIC_CMP_SWAP during Legalization, so existing backends should see no change in behaviour. If they wish to deal with the enhanced node instead, they can call setOperationAction on it. Beware: as a node with 2 results, it cannot be selected from TableGen. Currently, no use is made of the extra information provided in this patch. Test updates are almost entirely adapting the input IR to the new scheme. Summary for out of tree users: ------------------------------ + Legacy Bitcode files are upgraded during read. + Legacy assembly IR files will be invalid. + Front-ends must adapt to different type for "cmpxchg". + Backends should be unaffected by default. llvm-svn: 210903
