| * | GenStgAlt 3-tuple synonym --> Record type | doyougnu | 2022-03-02 | 1 | -5/+8 |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit alters GenStgAlt from a type synonym to a Record with field accessors. In pursuit of #21078, this is not a required change but cleans up several areas for nicer code in the upcoming js-backend, and in GHC itself. GenStgAlt: 3-tuple -> record Stg.Utils: GenStgAlt 3-tuple -> record Stg.Stats: StgAlt 3-tuple --> record Stg.InferTags.Rewrite: StgAlt 3-tuple -> record Stg.FVs: GenStgAlt 3-tuple -> record Stg.CSE: GenStgAlt 3-tuple -> record Stg.InferTags: GenStgAlt 3-tuple --> record Stg.Debug: GenStgAlt 3-tuple --> record Stg.Lift.Analysis: GenStgAlt 3-tuple --> record Stg.Lift: GenStgAlt 3-tuple --> record ByteCode.Instr: GenStgAlt 3-tuple --> record Stg.Syntax: add GenStgAlt helper functions Stg.Unarise: GenStgAlt 3-tuple --> record Stg.BcPrep: GenStgAlt 3-tuple --> record CoreToStg: GenStgAlt 3-tuple --> record StgToCmm.Expr: GenStgAlt 3-tuple --> record StgToCmm.Bind: GenStgAlt 3-tuple --> record StgToByteCode: GenStgAlt 3-tuple --> record Stg.Lint: GenStgAlt 3-tuple --> record Stg.Syntax: strictify GenStgAlt GenStgAlt: add haddock, some cleanup fixup: remove calls to pure, single ViewPattern StgToByteCode: use case over viewpatterns | ||||
| * | Suggestions due to hlint | Matthew Pickering | 2022-02-24 | 1 | -1/+0 |
| | | | | | | It turns out this job hasn't been running for quite a while (perhaps ever) so there are quite a few failures when running the linter locally. | ||||
| * | Tag inference work. | Andreas Klebinger | 2022-02-12 | 1 | -0/+124 |
| This does three major things: * Enforce the invariant that all strict fields must contain tagged pointers. * Try to predict the tag on bindings in order to omit tag checks. * Allows functions to pass arguments unlifted (call-by-value). The former is "simply" achieved by wrapping any constructor allocations with a case which will evaluate the respective strict bindings. The prediction is done by a new data flow analysis based on the STG representation of a program. This also helps us to avoid generating redudant cases for the above invariant. StrictWorkers are created by W/W directly and SpecConstr indirectly. See the Note [Strict Worker Ids] Other minor changes: * Add StgUtil module containing a few functions needed by, but not specific to the tag analysis. ------------------------- Metric Decrease: T12545 T18698b T18140 T18923 LargeRecord Metric Increase: LargeRecord ManyAlternatives ManyConstructors T10421 T12425 T12707 T13035 T13056 T13253 T13253-spj T13379 T15164 T18282 T18304 T18698a T1969 T20049 T3294 T4801 T5321FD T5321Fun T783 T9233 T9675 T9961 T19695 WWRec ------------------------- | |||||
