Alan Zimmerman pushed to branch wip/az/ghc-cpp at Glasgow Haskell Compiler / GHC Commits: 6e67fa08 by Ben Gamari at 2025-05-08T06:21:21-04:00 llvmGen: Fix built-in variable predicate Previously the predicate to identify LLVM builtin global variables was checking for `$llvm` rather than `@llvm` as it should. - - - - - a9d0a22c by Ben Gamari at 2025-05-08T06:21:22-04:00 llvmGen: Fix linkage of built-in arrays LLVM now insists that built-in arrays use Appending linkage, not Internal. Fixes #25769. - - - - - 9c6d2b1b by sheaf at 2025-05-08T06:22:11-04:00 Use mkTrAppChecked in ds_ev_typeable This change avoids violating the invariant of mkTrApp according to which the argument should not be a fully saturated function type. This ensures we don't return false negatives for type equality involving function types. Fixes #25998 - - - - - 75cadf81 by Ryan Hendrickson at 2025-05-08T06:22:55-04:00 haddock: Preserve indentation in multiline examples Intended for use with :{ :}, but doesn't look for those characters. Any consecutive lines with birdtracks will only have initial whitespace stripped up to the column of the first line. - - - - - fee9b351 by Cheng Shao at 2025-05-08T06:23:36-04:00 ci: re-enable chrome for wasm ghci browser tests Currently only firefox is enabled for wasm ghci browser tests, for some reason testing with chrome works on my machine but gets stuck on gitlab instance runners. This patch re-enables testing with chrome by passing `--no-sandbox`, since chrome sandboxing doesn't work in containers without `--cap-add=SYS_ADMIN`. - - - - - 282df905 by Vladislav Zavialov at 2025-05-09T03:18:25-04:00 Take subordinate 'type' specifiers into account This patch fixes multiple bugs (#22581, #25983, #25984, #25991) in name resolution of subordinate import lists. Bug #22581 ---------- In subordinate import lists, the use of the `type` namespace specifier used to be ignored. For example, this import statement was incorrectly accepted: import Prelude (Bool(type True)) Now it results in an error message: <interactive>:2:17: error: [GHC-51433] In the import of ‘Prelude’: a data type called ‘Bool’ is exported, but its subordinate item ‘True’ is not in the type namespace. Bug #25983 ---------- In subordinate import lists within a `hiding` clause, non-existent items led to a poor warning message with -Wdodgy-imports. Consider: import Prelude hiding (Bool(X)) The warning message for this import statement used to misreport the cause of the problem: <interactive>:3:24: warning: [GHC-56449] [-Wdodgy-imports] In the import of ‘Prelude’: an item called ‘Bool’ is exported, but it is a type. Now the warning message is correct: <interactive>:2:24: warning: [GHC-10237] [-Wdodgy-imports] In the import of ‘Prelude’: a data type called ‘Bool’ is exported, but it does not export any constructors or record fields called ‘X’. Bug #25984 ---------- In subordinate import lists within a `hiding` clause, non-existent items resulted in the entire import declaration being discarded. For example, this program was incorrectly accepted: import Prelude hiding (Bool(True,X)) t = True Now it results in an error message: <interactive>:2:5: error: [GHC-88464] Data constructor not in scope: True Bug #25991 ---------- In subordinate import lists, it was not possible to refer to a class method if there was an associated type of the same name: module M_helper where class C a b where type a # b (#) :: a -> b -> () module M where import M_helper (C((#))) This import declaration failed with: M.hs:2:28: error: [GHC-10237] In the import of ‘M_helper’: an item called ‘C’ is exported, but it does not export any children (constructors, class methods or field names) called ‘#’. Now it is accepted. Summary ------- The changes required to fix these bugs are almost entirely confined to GHC.Rename.Names. Other than that, there is a new error constructor BadImportNonTypeSubordinates with error code [GHC-51433].

This fix makes things a bit better but does not cure the underlying problem. - - - - - 7b2d1e6d by Simon Peyton Jones at 2025-05-11T03:24:47-04:00 Refine `noGivenNewtypeReprEqs` to account for quantified constraints This little MR fixes #26020. We are on the edge of completeness for newtype equalities (that doesn't change) but this MR makes GHC a bit more consistent -- and fixes the bug reported. - - - - - eaa8093b by Cheng Shao at 2025-05-11T03:25:28-04:00 wasm: mark freeJSVal as INLINE This patch marks `freeJSVal` as `INLINE` for the wasm backend. I noticed that the `freeJSVal` invocations are not inlined when inspecting STG/Cmm dumps of downstream libraries that use release build of the wasm backend. The performance benefit of inlining here is very modest, but so is the cost anyway; if you are using `freeJSVal` at all then you care about every potential chance to improve performance :) - - - - - eac196df by Cheng Shao at 2025-05-11T03:25:28-04:00 wasm: add zero length fast path for fromJSString This patch adds a zero length fast path for `fromJSString`; when marshaling a zero-length `JSString` we don't need to allocate an empty `ByteArray#` at all. - - - - - 008eb3de by Alan Zimmerman at 2025-05-11T09:30:18+01:00 GHC-CPP: first rough proof of concept Processes #define FOO #ifdef FOO x = 1 #endif Into [ITcppIgnored [L loc ITcppDefine] ,ITcppIgnored [L loc ITcppIfdef] ,ITvarid "x" ,ITequal ,ITinteger (IL {il_text = SourceText "1", il_neg = False, il_value = 1}) ,ITcppIgnored [L loc ITcppEndif] ,ITeof] In time, ITcppIgnored will be pushed into a comment - - - - - 089fecc2 by Alan Zimmerman at 2025-05-11T09:30:18+01:00 Tidy up before re-visiting the continuation mechanic - - - - - 487bb5dc by Alan Zimmerman at 2025-05-11T09:30:18+01:00 Switch preprocessor to continuation passing style Proof of concept, needs tidying up - - - - - 7edf6c54 by Alan Zimmerman at 2025-05-11T09:30:18+01:00 Small cleanup - - - - - 2b817f66 by Alan Zimmerman at 2025-05-11T09:30:18+01:00 Get rid of some cruft - - - - - 7872e670 by Alan Zimmerman at 2025-05-11T09:30:18+01:00 Starting to integrate.
