X86: expand atomics in IR instead of as MachineInstrs. The logic for expanding atomics that aren't natively supported in terms of cmpxchg loops is much simpler to express at the IR level. It also allows the normal optimisations and CodeGen improvements to help out with atomics, instead of using a limited set of possible instructions.. rdar://problem/13496295 llvm-svn: 212119

[X86] Make sure we do not clobber RBX with cmpxchg when used as a base pointer. cmpxchg[8|16]b uses RBX as one of its argument. In other words, using this instruction clobbers RBX as it is defined to hold one the input. When the backend uses dynamically allocated stack, RBX is used as a reserved register for the base pointer. Reserved registers have special semantic that only the target understands and enforces, because of that, the register allocator don’t use them, but also, don’t try to make sure they are used properly (remember it does not know how they are supposed to be used). Therefore, when RBX is used as a reserved register but defined by something that is not compatible with that use, the register allocator will not fix the surrounding code to make sure it gets saved and restored properly around the broken code. This is the responsibility of the target to do the right thing with its reserved register. To fix that, when the base pointer needs to be preserved, we use a different pseudo instruction for cmpxchg that save rbx. That pseudo takes two more arguments than the regular instruction: - One is the value to be copied into RBX to set the proper value for the comparison. - The other is the virtual register holding the save of the value of RBX as the base pointer. This saving is done as part of isel (i.e., we emit a copy from rbx). cmpxchg_save_rbx <regular cmpxchg args>, input_for_rbx_reg, save_of_rbx_as_bp This gets expanded into: rbx = copy input_for_rbx_reg cmpxchg <regular cmpxchg args> rbx = save_of_rbx_as_bp Note: The actual modeling of the pseudo is a bit more complicated to make sure the interferes that appears after the pseudo gets expanded are properly modeled before that expansion. This fixes PR26883. llvm-svn: 263325

; machine scheduler and copy coalescer do not mess up with physical

[X86] Handle COPYs of physregs better (regalloc hints) Enable enableMultipleCopyHints() on X86. Original Patch by @jonpa: While enabling the mischeduler for SystemZ, it was discovered that for some reason a test needed one extra seemingly needless COPY (test/CodeGen/SystemZ/call-03.ll). The handling for that is resulted in this patch, which improves the register coalescing by providing not just one copy hint, but a sorted list of copy hints. On SystemZ, this gives ~12500 less register moves on SPEC, as well as marginally less spilling. Instead of improving just the SystemZ backend, the improvement has been implemented in common-code (calculateSpillWeightAndHint(). This gives a lot of test failures, but since this should be a general improvement I hope that the involved targets will help and review the test updates.

[x86] Fix an amazing goof in the handling of sub, or, and xor lowering. The comment for this code indicated that it should work similar to our handling of add lowering above: if we see uses of an instruction other than flag usage and store usage, it tries to avoid the specialized X86ISD::* nodes that are designed for flag+op modeling and emits an explicit test. Problem is, only the add case actually did this. In all the other cases, the logic was incomplete and inverted. Any time the value was used by a store, we bailed on the specialized X86ISD node. All of this appears to have been historical where we had different logic here. =/ Turns out, we have quite a few patterns designed around these nodes. We should actually form them. I fixed the code to match what we do for add, and it has quite a positive effect just within some of our test cases. The only thing close to a regression I see is using: notl %r testl %r, %r instead of: xorl -1, %r But we can add a pattern or something to fold that back out. The improvements seem more than worth this. I've also worked with Craig to update the comments to no longer be actively contradicted by the code. =[ Some of this still remains a mystery to both Craig and myself, but this seems like a large step in the direction of consistency and slightly more accurate comments. Many thanks to Craig for help figuring out this nasty stuff. Differential Revision: https://reviews.llvm.org/D37096 llvm-svn: 311737

[opaque pointer type] Add textual IR support for explicit type parameter to load instruction Essentially the same as the GEP change in r230786. A similar migration script can be used to update test cases, though a few more test case improvements/changes were required this time around: (r229269-r229278) import fileinput import sys import re pat = re.compile(r"((?:=|:|^)\s*load (?:atomic )?(?:volatile )?(.*?))(| addrspace\(\d+\) *)\*($| *(?:%|@|null|undef|blockaddress|getelementptr|addrspacecast|bitcast|inttoptr|\[\[[a-zA-Z]|\{\{).*$)") for line in sys.stdin: sys.stdout.write(re.sub(pat, r"\1, \2\3*\4", line)) Reviewers: rafael, dexonsmith, grosser Differential Revision: http://reviews.llvm.org/D7649 llvm-svn: 230794

X86: expand atomics in IR instead of as MachineInstrs. The logic for expanding atomics that aren't natively supported in terms of cmpxchg loops is much simpler to express at the IR level. It also allows the normal optimisations and CodeGen improvements to help out with atomics, instead of using a limited set of possible instructions.. rdar://problem/13496295 llvm-svn: 212119
