Hannes Siebenhandl pushed to branch wip/fendor/ann-frame at Glasgow Haskell Compiler / GHC Commits: 8679cc5d by fendor at 2025-07-18T09:42:16+02:00 Extend Backtraces to allow configuration of stack decoders Allow the user to overwrite the default stack-decoders in `Backtraces`. Users can then experiment with custom stack decoders, or tweak the output of the stack trace to their liking. We store the stack decoders for each of the supported backtraces in `DisplayBacktraceMechanisms` in a global `IORef`. When collecting `Backtraces`, we also ask for the currently configured stack decoders (specified via `DisplayBacktraceMechanisms`) and use them for printing the `Backtraces`. - - - - - 83e0359f by Ben Gamari at 2025-07-18T09:42:19+02:00 Annotate frame - - - - - 48551e2f by fendor at 2025-07-18T09:42:19+02:00 WIP: Introduce stack frame annotation helpers and extend ghc-heap stack decoder - - - - - e741f34a by fendor at 2025-07-18T09:43:00+02:00 WIP: move iterator based stack decoder to ghc-internal - - - - - 53 changed files: - compiler/GHC/Builtin/primops.txt.pp - compiler/GHC/StgToCmm/Prim.hs - compiler/GHC/StgToJS/Prim.hs - libraries/base/src/Control/Exception/Backtrace.hs - libraries/ghc-experimental/ghc-experimental.cabal.in - + libraries/ghc-experimental/src/GHC/Stack/Annotation/Experimental.hs - libraries/ghc-heap/GHC/Exts/Heap/ClosureTypes.hs - libraries/ghc-heap/GHC/Exts/Heap/Closures.hs - libraries/ghc-heap/GHC/Exts/Heap/InfoTable.hsc - libraries/ghc-heap/GHC/Exts/Stack.hs - libraries/ghc-heap/GHC/Exts/Stack/Constants.hsc - libraries/ghc-heap/GHC/Exts/Stack/Decode.hs - libraries/ghc-heap/cbits/Stack.cmm - + libraries/ghc-heap/tests/stack-annotation/Makefile - + libraries/ghc-heap/tests/stack-annotation/all.T - + libraries/ghc-heap/tests/stack-annotation/ann_frame001.hs - + libraries/ghc-heap/tests/stack-annotation/ann_frame001.stdout - + libraries/ghc-heap/tests/stack-annotation/ann_frame002.hs - + libraries/ghc-heap/tests/stack-annotation/ann_frame002.stdout - + libraries/ghc-heap/tests/stack-annotation/ann_frame003.hs - + libraries/ghc-heap/tests/stack-annotation/ann_frame004.hs - + libraries/ghc-internal/cbits/HeapPrim.cmm - + libraries/ghc-internal/cbits/Stack.cmm - + libraries/ghc-internal/cbits/Stack_c.c - libraries/ghc-internal/ghc-internal.cabal.in - libraries/ghc-internal/src/GHC/Internal/ClosureTypes.hs - libraries/ghc-internal/src/GHC/Internal/Exception/Backtrace.hs - + libraries/ghc-internal/src/GHC/Internal/Heap/Closures.hs - + libraries/ghc-internal/src/GHC/Internal/Heap/Constants.hsc - + libraries/ghc-internal/src/GHC/Internal/Heap/InfoTable.hsc - + libraries/ghc-internal/src/GHC/Internal/Heap/InfoTable/Types.hsc - + libraries/ghc-internal/src/GHC/Internal/Heap/InfoTableProf.hsc - + libraries/ghc-internal/src/GHC/Internal/Heap/ProfInfo/Types.hs - + libraries/ghc-internal/src/GHC/Internal/Stack/Annotation.hs - libraries/ghc-internal/src/GHC/Internal/Stack/CloneStack.hs - + libraries/ghc-internal/src/GHC/Internal/Stack/Constants.hsc - + libraries/ghc-internal/src/GHC/Internal/Stack/Decode.hs - rts/ClosureFlags.c - rts/LdvProfile.c - rts/PrimOps.cmm - rts/Printer.c - rts/RetainerProfile.c - rts/TraverseHeap.c - rts/include/rts/storage/ClosureTypes.h - rts/include/rts/storage/Closures.h - rts/js/profiling.js - rts/sm/Compact.c - rts/sm/Evac.c - rts/sm/NonMovingMark.c - rts/sm/Sanity.c - rts/sm/Scav.c - testsuite/tests/interface-stability/base-exports.stdout - utils/deriveConstants/Main.hs The diff was not included because it is too large.
