Alan Zimmerman pushed to branch wip/az/exactprint-annotation-rationalisation at Glasgow Haskell Compiler / GHC Commits: 192be0b6 by Luite Stegeman at 2026-09-07T19:43:36-04:00 rts: fix ctoi_tuple_spill_words getting out of sync Fix a few places that were not updating ctoi_tuple_spill_words correctly, leading to corruption/crashes when dealing with large unboxed tuples in bytecode: - captureContinuationAndAbort - findRetryFrameHelper/findAtomicallyFrameHelper - interpretBCO bci_BRK_FUN fixes #27633 - - - - - 604eb43c by Simon Jakobi at 2026-09-07T19:44:15-04:00 Hadrian: don't capture the testsuite driver's output (#27780) a6061455d54 switched the Testsuite RunTest case from Shake's cmd to the cmd' wrapper. cmd' always captures stdout and stderr, and since the caller asks for Exit, it returns without dumping what it captured. As a result the testsuite output no longer appears in CI job logs: failures, performance metrics and the summary were lost with the job. Use cmdExe, the uncaptured cmd, as the other plain-cmd sites in that commit do. Fixes #27780.

Fixes #27477 - - - - - f8b2bd8f by Alan Zimmerman at 2026-09-08T09:39:12-04:00 EPA Fix HsCmdDo exact print with comments Exact printing of HsCmdDo was ignoring the location for the do statements, and this is an annotation that can have comments in it. Update it so we print the statements as a unit, including any comments. Also add the result of auditing that we capture comments in all needed places, noting that the remaining Anno SrcSpan instances are benign. - - - - - 430967ab by Duncan Coutts at 2026-09-09T11:07:01+01:00 Reorder cmm decls in HeapStackCheck for a better logical grouping And put more section headers in to deliniate the groups. We're about to add more here, so better to organise it first. - - - - - 344080fd by Duncan Coutts at 2026-09-09T11:07:01+01:00 Add raisePrimIOException and add it to RTS<->ghc-internal API The raisePrimIOException is a new helper function that I/O primops will use to help them report I/O errors. This is implemented in Haskell (since that's a lot easier), but has a calling convention that is easy(ish) to use from Cmm in the I/O primops. So we add it to the RTS API struct, and since we'll use it from Cmm we also need a field accessor macro for cmm (in deriveConstants). See the Note about how we cannot have nice things due to async exceptions and thunks preventing us from using catch. - - - - - cfdb3399 by Duncan Coutts at 2026-09-09T11:07:01+01:00 Add new blocking functions for I/O primops See the Note [Thread blocking for new I/O primops], and the Note [Calling convention for raisePrimIOException]. The point is, it will allow us to report synchronous exceptions from I/O primops, and do so much more flexibly. Previously the I/O managers could only report async exceptions and only nullary exceptions. This was OK historically, but no good as we add more I/O managers and expand the range of I/O operations we support. - - - - - f09c09d8 by Duncan Coutts at 2026-09-09T11:07:01+01:00 Change the encoding of results from the I/O manager to I/O primops Previously we just had async continue or heap overflow. We now extend what we can report with synchronous success, and synchronous failure with an errno. See Note [Encoding of result of I/O manager operations] We don't use these two new cases yet, but we will. In particular an epoll I/O manager needs to be able to report synchronous success or failure for waitRead#/waitWrite#. - - - - - 30f074d9 by Duncan Coutts at 2026-09-09T11:07:01+01:00 Switch waitRead/Write# to use new blocking return frames and update the I/O managers to set the result before resuming the blocked threads. This makes it possible for I/O managers to report synchronous exceptions from the I/O primops, but that will be done in a subsequent commit. - - - - - a8786ced by Duncan Coutts at 2026-09-09T11:07:01+01:00 Switch Poll and Select I/O managers to report sync exceptions rather than using raiseAsync with blockedOnBadFD_closure. This uses the new mechanism in the blocking frame return code to report synchronous exceptions. - - - - - 7a9df79a by Duncan Coutts at 2026-09-09T11:07:01+01:00 Remove now-unused blockedOnBadFD It was previously thrown by the select and poll I/O managers, but now they use raisePrimIOException (with an EBADF errno). - - - - - 6b0424e3 by Duncan Coutts at 2026-09-09T11:07:01+01:00 Improve the docs for delay# waitRead# and waitWrite# Document that the waitRead/Write# can throw exceptions (this was true before too), and that all of them are async exception cancellation points. - - - - - afeb2c30 by Duncan Coutts at 2026-09-09T20:08:58-04:00 Enable printf warnings for trace functions and fix resulting warnings Most of the existing printf-style functions are annotated with attributes to enable gcc/clang warnings for the printf format string, but several trace functions in Trace.h were missing this annotation. Enable them, and fix the resulting warnings. - - - - - 9a442c93 by Alan Zimmerman at 2026-09-09T20:09:36-04:00 EPA: Exact print ConDeclGADT without custom enterAnn !16321 brought in explicit capture of parens in a ConDeclGADT. The ExactPrint update introduced a modification of the fundamental function in exact printing, `enterAnn`, by splitting it into a version allowing injection of functionality normally handled by the ExactPrint class methods. This commit refactors that code, to restore the prior `enterAnn` version, by following the convention in ExactPrint of introducing a helper data structure with its own `ExactPrint` instance to achieve the same effect. - - - - - 4e9297ea by Simon Jakobi at 2026-09-11T08:32:45-04:00 ci: Actually pass --ignore-perf-failures to the testsuite driver 684c0018d9 changed the IGNORE_PERF_FAILURES handling to append to RUNTEST_ARGS with bash array syntax, but the three use sites still expand RUNTEST_ARGS as a scalar, which yields only the first array element. The appended flag was therefore dropped in every job, so perf improvements kept failing Marge Bot batches and master pipelines, contrary to #19562. Append as a string instead, matching the existing --force-colors append in test_hadrian. Fixes #27563.

None of them make sense at the type level, so restriction (R3) of Note [Type data declarations] now covers all of them. Fixes #27732.

Some of these are in a layout context (DoExpr, MDoExpr), others are not (ListComp, MonadComp). We are moving towards using AnnList only in layout contexts, so we switch the HsDo TTG annotation from holding an AnnList for this, to holding Either (EpToken "[", EpToken "]") AnnList This also allows us to trim down AnnListBrackets to only have braces or None, thereby opening the door for unification with the existing layout context data type EpLayout. - - - - - 99dc2235 by Alan Zimmerman at 2026-09-12T17:25:02+01:00 EPA: Add specific layout field to AnnList Up to now AnnList has effectively served to represent lists of things having layout, regardless of whether they do or not. In Haskell, layout is optional in many places, as there is also an alternative syntax using braces and semi-colons, which is free-form. This commit introduces AnnListLayout, a data structure capturing this distinction. It is deliberately set up similarly to EpLayout, so that these two can be merged in time. - - - - - 5017a5e9 by Alan Zimmerman at 2026-09-12T17:25:02+01:00 EPA: Use EpaLocation in EpVirtualBraces reword: EPA Use vocurly as basis for AnnListLayout For the existing cases that populate AnnList.

The internal TTG extension points only carry exact print annotations related to printing the item within its bounds. This change brings back the problem of EmptyLocalBinds, which by definition cannot have a location. These get a noSrcSpan location, which is ignored in the exact printing process. - - - - - af74d4a1 by Alan Zimmerman at 2026-09-12T18:18:52+01:00 EPA: Use AnnList in HsMultiIf It introduces layout, capture it - - - - - dff39adb by Alan Zimmerman at 2026-09-12T18:18:52+01:00 EPA: Use AnnList in DecBrl - - - - - bdb6df32 by Alan Zimmerman at 2026-09-12T18:18:52+01:00 EPA: Replace AnnListLayout / AnnListBrackets with EpLayout - - - - - 7d1214a9 by Alan Zimmerman at 2026-09-12T18:18:52+01:00 WIP: setLayoutBoth inside markAnnListA Current problem is it is a global one-shot, and MG has one too Check: is it needed? if so, honouring EpLayout may be needed - - - - - 5df232f9 by Alan Zimmerman at 2026-09-12T18:18:52+01:00 EPA some tests for layout.

This is a technical requirement due to the way comment allocation happens during the makeDelta processing. Comments are queued for printing, and as soon as any non-comment is to be printed, the pending comments before that position are printed, and in makeDelta processing these attached as preceding comments to the thing just printed. The means they end up captured inside the layout region of the AnnList item. So for foo = x where -- comment x = 3 the comment ends up as a preceding comment of `x = 3`, inside the layout, and prints as foo = x where -- comment x = 3 - - - - - ad1401b8 by Alan Zimmerman at 2026-09-12T18:18:52+01:00 EPA: Make IPBinds LocatedA - - - - - 579b1123 by Alan Zimmerman at 2026-09-12T18:18:52+01:00 EPA: Make ClsInstDecl decls LocatedA - - - - - 0218256e by Alan Zimmerman at 2026-09-12T18:18:52+01:00 EPA: Make ClassDecls decls LocatedA - - - - - dc8c9efa by Alan Zimmerman at 2026-09-12T18:18:52+01:00 EPA: Make ClosedTypeFamily equations Located For FamilyDecl/ClosedTypeFamily - - - - - 497bb000 by Alan Zimmerman at 2026-09-12T18:18:52+01:00 EPA: Make dd_cons located - - - - - 3d7d77df by Alan Zimmerman at 2026-09-12T18:18:52+01:00 EPA: Make HsMultiIf options located - - - - - e4e7df9d by Alan Zimmerman at 2026-09-12T18:18:52+01:00 EPA: Make DecBrl contents LocatedA - - - - - 86c9a465 by Alan Zimmerman at 2026-09-12T18:18:52+01:00 EPA: Located do statements - - - - - 29141ac6 by Alan Zimmerman at 2026-09-12T18:18:52+01:00 EPA: Print RecStmt located - - - - - f9d73080 by Alan Zimmerman at 2026-09-12T18:18:52+01:00 EPA: HsCmdDo Located - - - - - e901e0c9 by Alan Zimmerman at 2026-09-12T18:18:52+01:00 Extend Test20297 for additional occurrences - - - - - 39b57cab by Alan Zimmerman at 2026-09-12T18:18:52+01:00 EPA: Tweak PatSynBind location for comments - - - - - 0fbbcadb by Alan Zimmerman at 2026-09-12T18:42:05+01:00 EPA: WIP, add test for where ;; ValBinds - - - - - e79fc375 by Alan Zimmerman at 2026-09-12T18:42:05+01:00 EPA: Make EpVirtualBraces noSpanAnchor if no contents Otherwise the vocurly is emitted at the start of the next item parsed Check: is this needed, or just a check for empty contents? - - - - - 5ab16646 by Alan Zimmerman at 2026-09-12T18:42:47+01:00 WIP: turn of exactprint debug printing - - - - - 0c48a521 by Alan Zimmerman at 2026-09-12T18:43:04+01:00 EPA: Remove CanUpdateAnchorOnly - - - - - dcab4f1d by Alan Zimmerman at 2026-09-12T18:43:04+01:00 Plan update DO NOT COMMIT - - - - - 74ad6345 by Alan Zimmerman at 2026-09-12T18:43:04+01:00 EPA: First pass implementation of HsList, for ClassDecls Just as a straight list replacement to start with, no payload.
