735f4671 - [APInt] Normalize naming on keep constructors / predicate methods.

Thu, 09 Sep 2021 05:13:13 +0000

[APInt] Normalize naming on keep constructors / predicate methods.This renames the primary methods for creating a zero value to `getZero`instead of `getNullValue` and renames predicates like `isAllOnesValue`to simply `isAllOnes`. This achieves two things:1) This starts standardizing predicates across the LLVM codebase, following (in this case) ConstantInt. The word "Value" doesn't convey anything of merit, and is missing in some of the other things.2) Calling an integer "null" doesn't make any sense. The original sin here is mine and I've regretted it for years. This moves us to calling it "zero" instead, which is correct!APInt is widely used and I don't think anyone is keen to take massive sourcebreakage on anything so core, at least not all in one go. As such, thisdoesn't actually delete any entrypoints, it "soft deprecates" them with acomment.Included in this patch are changes to a bunch of the codebase, but there aremore. We should normalize SelectionDAG and other APIs as well, which wouldmake the API change more mechanical.Differential Revision: https://reviews.llvm.org/D109483 List of files: /llvm-project-15.0.7/llvm/unittests/CodeGen/GlobalISel/KnownBitsTest.cpp

fae05692 - CodeGen: Print/parse LLTs in MachineMemOperands

Thu, 20 May 2021 02:25:51 +0000

CodeGen: Print/parse LLTs in MachineMemOperandsThis will currently accept the old number of bytes syntax, and convertit to a scalar. This should be removed in the near future (I think Iconverted all of the tests already, but likely missed a few).Not sure what the exact syntax and policy should be. We can continueprinting the number of bytes for non-generic instructions to avoidtest churn and only allow non-scalar types for generic instructions.This will currently print the LLT in parentheses, but accept parsingthe existing integers and implicitly converting to scalar. Theparentheses are a bit ugly, but the parser logic seems unable to dealwithout either parentheses or some keyword to indicate the start of atype.
