R600/SI: Custom lower fround This fixes it for SI. It also removes the pattern used previously for Evergreen for f32. I'm not sure if the the new R600 output is better or not, but it uses 1 fewer instructions if BFI is available. llvm-svn: 226682

AMDGPU: Mark all unspecified CC functions in tests as amdgpu_kernel Currently the default C calling convention functions are treated the same as compute kernels. Make this explicit so the default calling convention can be changed to a non-kernel. Converted with perl -pi -e 's/define void/define amdgpu_kernel void/' on the relevant test directories (and undoing in one place that actually wanted a non-kernel). llvm-svn: 298444

[AMDGPU] Remove dubious logic in bidirectional list scheduler Summary: pickNodeBidirectional tried to compare the best top candidate and the best bottom candidate by examining TopCand.Reason and BotCand.Reason. This is unsound because, after calling pickNodeFromQueue, Cand.Reason does not reflect the most important reason why Cand was chosen. Rather it reflects the most recent reason why it beat some other potential candidate, which could have been for some low priority tie breaker reason. I have seen this cause problems where TopCand is a good candidate, but because TopCand.Reason is ORDER (which is very low priority) it is repeatedly ignored in favour of a mediocre BotCand. This is not how bidirectional scheduling is supposed to work. To fix this I changed the code to always compare TopCand and BotCand directly, like the generic implementation of pickNodeBidirectional does. This removes some uncommented AMDGPU-specific logic; if this logic turns out to be important then perhaps it could be moved into an override of tryCandidate instead. Graphics shader benchmarking on gfx10 shows a lot more positive than negative effects from this change.

%tid = call i32 @llvm.amdgcn.workitem.id.x() #1
[opaque pointer type] Add textual IR support for explicit type parameter to 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

Making it legal makes SI_INDIRECT patterns work. There is more work to do in subsequent changes: 1. We initialize m0 twice to access each dword. It shall be possible to only do it once and increment base register number instead. 2. We also need v16i64/v16f64 but these first need to be added to tablegen.

[codegen,amdgpu] Enhance MIR DIE and re-arrange it for AMDGPU. Summary: - `dead-mi-elimination` assumes MIR in the SSA form and cannot be arranged after phi elimination or DeSSA. It's enhanced to handle the dead register definition by skipping use check on it. Once a register def is `dead`, all its uses, if any, should be `undef`. - Re-arrange the DIE in RA phase for AMDGPU by placing it directly after `detect-dead-lanes`. - Many relevant tests are refined due to different register assignment.

[AMDGPU] Bundle loads before post-RA scheduler We are relying on atrificial DAG edges inserted by the MemOpClusterMutation to keep loads and stores together in the post-RA scheduler. This does not work all the time since it allows to schedule a completely independent instruction in the middle of the cluster. Removed the DAG mutation and added pass to bundle already clustered instructions. These bundles are unpacked before the memory legalizer because it does not work with bundles but also because it allows to insert waitcounts in the middle of a store cluster. Removing artificial edges also allows a more relaxed scheduling. Differential Revision: https://reviews.llvm.org/D72737

AMDGPU: Mark all unspecified CC functions in tests as amdgpu_kernel Currently the default C calling convention functions are treated the same as compute kernels. Make this explicit so the default calling convention can be changed to a non-kernel.

[AMDGPU] Make v4i64/v4f64/v8i64/v8f64 legal We can produce such vectors in the Promote Alloca pass, but we are unable to use movrel to operate it and lower via scratch. Making it legal makes SI_INDIRECT patterns work. There is more work to do in subsequent changes: 1. We initialize m0 twice to access each dword. It shall be possible to only do it once and increment base register number instead. 2. We also need v16i64/v16f64 but these first need to be added to tablegen.

R600/SI: Custom lower fround This fixes it for SI. It also removes the pattern used previously for Evergreen for f32. I'm not sure if the the new R600 output is better or not, but it uses 1 fewer instructions if BFI is available. llvm-svn: 226682
