* Fix parsing of rpaths which include spaces in runInjectRPathsMatthew Pickering2021-08-181-5/+26
| | | | | | | | | | | | | | | | The logic didn't account for the fact that the paths could contain spaces before which led to errors such as the following from install_name_tool. Stderr ( T14304 ): Warning: -rtsopts and -with-rtsopts have no effect with -shared. Call hs_init_ghc() from your main() function to set these options. error: /nix/store/a6j5761iy238pbckxq2xrhqr2d5kra4m-cctools-binutils-darwin-949.0.1/bin/install_name_tool: for: dist/build/libHSp-0.1-ghc8.10.6.dylib (for architecture arm64) option "-add_rpath /Users/matt/ghc/bindisttest/install dir/lib/ghc-8.10.6/ghc-prim-0.6.1" would duplicate path, file already has LC_RPATH for: /Users/matt/ghc/bindisttest/install dir/lib/ghc-8.10.6/ghc-prim-0.6.1 `install_name_tool' failed in phase `Install Name Tool'. (Exit code: 1) Fixes #20212 This apparently also fixes #20026, which is a nice surprise.
* Linker/darwin: Properly honour -fno-use-rpathsMatthew Pickering2021-06-201-0/+2
| | | | | | | | | | | | | The specification is now simple * On linux, use `-Xlinker -rpath -Xlinker` to set the rpath of the executable * On darwin, never use `-Xlinker -rpath -Xlinker`, always inject the rpath afterwards, see `runInjectRPaths`. * If `-fno-use-rpaths` is passed then *never* inject anything into the rpath. Fixes #20004
* Move loader state into InterpSylvain Henry2021-03-231-5/+4
| | | | | | | | | | | | | | | | | | The loader state was stored into HscEnv. As we need to have two interpreters and one loader state per interpreter in #14335, it's natural to make the loader state a field of the Interp type. As a side effect, many functions now only require a Interp parameter instead of HscEnv. Sadly we can't fully free GHC.Linker.Loader of HscEnv yet because the loader is initialised lazily from the HscEnv the first time it is used. This is left as future work. HscEnv may not contain an Interp value (i.e. hsc_interp :: Maybe Interp). So a side effect of the previous side effect is that callers of the modified functions now have to provide an Interp. It is satisfying as it pushes upstream the handling of the case where HscEnv doesn't contain an Interpreter. It is better than raising a panic (less partial functions, "parse, don't validate", etc.).
* Refactor LoggerSylvain Henry2021-02-131-5/+6
| | | | | | | | | | | | | | | | | | | | | Before this patch, the only way to override GHC's default logging behavior was to set `log_action`, `dump_action` and `trace_action` fields in DynFlags. This patch introduces a new Logger abstraction and stores it in HscEnv instead. This is part of #17957 (avoid storing state in DynFlags). DynFlags are duplicated and updated per-module (because of OPTIONS_GHC pragma), so we shouldn't store global state in them. This patch also fixes a race in parallel "--make" mode which updated the `generatedDumps` IORef concurrently. Bump haddock submodule The increase in MultilayerModules is tracked in #19293. Metric Increase: MultiLayerModules

* Add explicit import lists to Data.List importsOleg Grenrus2021-01-291-1/+1
| | | | | | | | | | | | | Related to a future change in Data.List, https://downloads.haskell.org/ghc/8.10.3/docs/html/users_guide/using-warnings.html?highlight=wcompat#ghc-flag--Wcompat-unqualified-imports Companion pull&merge requests: - https://github.com/judah/haskeline/pull/153 - https://github.com/haskell/containers/pull/762 - https://gitlab.haskell.org/ghc/packages/hpc/-/merge_requests/9 After these the actual change in Data.List should be easy to do.
* Move Unit related fields from DynFlags to HscEnvSylvain Henry2020-12-141-40/+10
| | | | | | | | | | | | | The unit database cache, the home unit and the unit state were stored in DynFlags while they ought to be stored in the compiler session state (HscEnv). This patch fixes this. It introduces a new UnitEnv type that should be used in the future to handle separate unit environments (especially host vs target units). Related to #17957 Bump haddock submodule
* Linker: reorganize linker related codeSylvain Henry2020-11-031-0/+183
Move linker related code into GHC.Linker. Previously it was scattered into GHC.Unit.State, GHC.Driver.Pipeline, GHC.Runtime.Linker, etc. Add documentation in GHC.Linker
