Andreas Klebinger pushed to branch wip/andreask/occ_anal_tuning at Glasgow Haskell Compiler / GHC Commits: 1275d360 by Matthew Pickering at 2025-10-03T06:05:56-04:00 testsuite: Use ghci_ways to set ways in PackedDataCon/UnboxedTuples/UnliftedDataTypeInterp tests These tests reimplemented the logic from `valid_way` in order to determine what ways to run. It's easier to use this combination of `only_ways` and `extra_ways` to only run in GHCi ways and always run in GHCi ways. - - - - - c06b534b by Matthew Pickering at 2025-10-03T06:06:40-04:00 Rename interpreterBackend to bytecodeBackend This is preparation for creating bytecode files. The "interpreter" is one way in which we can run bytecode objects. It is more accurate to describe that the backend produces bytecode, rather than the means by which the code will eventually run. The "interpreterBackend" binding is left as a deprecated alias. - - - - - 41bdb16f by Andreas Klebinger at 2025-10-06T18:04:34-04:00 Add a perf test for #26425 - - - - - 1da0c700 by Andreas Klebinger at 2025-10-06T18:05:14-04:00 Testsuite: Silence warnings about Wx-partial in concprog001 - - - - - ec22d744 by Andreas Klebinger at 2025-10-07T08:03:44+00:00 Try using a strict env for OccAnal - - - - - 26 changed files: - compiler/GHC.hs - compiler/GHC/Core/Opt/OccurAnal.hs - compiler/GHC/Data/Word64Map/Internal.hs - compiler/GHC/Driver/Backend.hs - compiler/GHC/Driver/Backend/Internal.hs - compiler/GHC/Driver/Downsweep.hs - compiler/GHC/Driver/Pipeline.hs - compiler/GHC/Driver/Session.hs - compiler/GHC/Types/Unique/FM.hs - compiler/GHC/Types/Var/Env.hs - docs/users_guide/extending_ghc.rst - ghc/Main.hs - testsuite/driver/testglobals.py - testsuite/driver/testlib.py - testsuite/tests/concurrent/prog001/all.T - testsuite/tests/driver/T5313.hs - testsuite/tests/ghc-api/T10052/T10052.hs - testsuite/tests/ghc-api/T8639_api.hs - testsuite/tests/ghc-api/apirecomp001/myghc.hs - testsuite/tests/ghci-wasm/T26431.hs - testsuite/tests/ghci/linking/dyn/T3372.hs - testsuite/tests/ghci/should_run/PackedDataCon/packeddatacon.T - testsuite/tests/ghci/should_run/UnboxedTuples/unboxedtuples.T - testsuite/tests/ghci/should_run/UnliftedDataTypeInterp/unlifteddatatypeinterp.T - + testsuite/tests/perf/compiler/T26425.hs - testsuite/tests/perf/compiler/all.T Changes: ===================================== compiler/GHC.hs ===================================== @@ -30,7 +30,7 @@ module GHC ( -- * Flags and settings DynFlags(..), GeneralFlag(..), Severity(..), Backend, gopt, - ncgBackend, llvmBackend, viaCBackend, interpreterBackend, noBackend, + ncgBackend, llvmBackend, viaCBackend, bytecodeBackend, interpreterBackend, noBackend, GhcMode(..), GhcLink(..), parseDynamicFlags, parseTargetFiles, getSessionDynFlags, ===================================== compiler/GHC/Core/Opt/OccurAnal.hs ===================================== @@ -10,6 +10,10 @@ -- bad for performance, so I increased the limit to allow it to unbox -- consistently. +-- {-# OPTIONS_GHC -ddump-simpl -ddump-stg -dumpdir dumps -ddump-to-file #-} +-- {-# OPTIONS_GHC -fdistinct-constructor-tables -finfo-table-map #-} +-- {-# OPTIONS_GHC -ticky -ticky-allocd -ticky-LNE #-} + {- (c) The GRASP/AQUA Project, Glasgow University, 1992-1998 @@ -984,7 +988,7 @@ occAnalBind !env lvl ire (NonRec bndr rhs) thing_inside combine = -- Analyse the RHS and /then/ the body let -- Analyse the rhs first, generating rhs_uds !(rhs_uds_s, bndr', rhs') = occAnalNonRecRhs env lvl ire mb_join bndr rhs - rhs_uds = foldr1 orUDs rhs_uds_s -- NB: orUDs.
