* JS: replace "js" architecture with "javascript"Sylvain Henry2023-02-061-1/+1
| | | | | | | | | | | | | | | Despite Cabal supporting any architecture name, `cabal --check` only supports a few built-in ones. Sadly `cabal --check` is used by Hackage hence using any non built-in name in a package (e.g. `arch(js)`) is rejected and the package is prevented from being uploaded on Hackage. Luckily built-in support for the `javascript` architecture was added for GHCJS a while ago. In order to allow newer `base` to be uploaded on Hackage we make the switch from `js` to `javascript` architecture. Fixes #22740. Co-authored-by: Ben Gamari <ben@smart-cactus.org>
* testsuite: req_smp --> req_target_smp, req_ghc_smpSylvain Henry2023-01-182-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | See #22630 and !9552 This commit: - splits req_smp into req_target_smp and req_ghc_smp - changes the testsuite driver to calculate req_ghc_smp - changes a handful of tests to use req_target_smp instead of req_smp - changes a handful of tests to use req_host_smp when needed The problem: - the problem this solves is the ambiguity surrounding req_smp - on master req_smp was used to express the constraint that the program being compiled supports smp _and_ that the host RTS (i.e., the RTS used to compile the program) supported smp. Normally that is fine, but in cross compilation this is not always the case as was discovered in #22630. The solution: - Differentiate the two constraints: - use req_target_smp to say the RTS the compiled program is linked with (and the platform) supports smp - use req_host_smp to say the RTS the host is linked with supports smp WIP: fix req_smp (target vs ghc) add flag to separate bootstrapper split req_smp -> req_target_smp and req_ghc_smp update tests smp flags cleanup and add some docstrings only set ghc_with_smp to bootstrapper on S1 or CC Only set ghc_with_smp to bootstrapperWithSMP of when testing stage 1 and cross compiling test the RTS in config/ghc not hadrian re-add ghc_with_smp fix and align req names fix T11760 to use req_host_smp test the rts directly, avoid python 3.5 limitation test the compiler in a try block align out of tree and in tree withSMP flags mark failing tests as host req smp testsuite: req_host_smp --> req_ghc_smp Fix ghc vs host, fix ghc_with_smp leftover

* testsuite: correct sleep() signature in T5611Cheng Shao2022-11-112-4/+6
| | | | | In libc, sleep() returns an integer. The ccall type signature should match the libc definition, otherwise it causes linker error on wasm.
* base: Fix races in IOManager (setNumCapabilities,closeFdWith)Douglas Wilson2022-08-101-1/+0
| | | | | | | | | | | | | Fix for #21651 Fixes three bugs: - writes to eventManager should be atomic. It is accessed concurrently by ioManagerCapabilitiesChanged and closeFdWith. - The race in closeFdWith described in the ticket. - A race in getSystemEventManager where it accesses the 'IOArray' in 'eventManager' before 'ioManagerCapabilitiesChanged' has written to 'eventManager', causing an Array Index exception. The fix here is to 'yield' and retry.
* testsuite: 21651 add test for closeFdWith + setNumCapabilitiesDouglas Wilson2022-08-103-1/+135
| | | | | This bug does not affect windows, which does not use the base module GHC.Event.Thread.
* Change GHC.Prim to GHC.Exts in docs and testsKrzysztof Gogolewski2022-04-015-5/+4

* Minor cleanupKrzysztof Gogolewski2022-04-011-2/+1
| | | | | | | | | | | - Remove unused functions exprToCoercion_maybe, applyTypeToArg, typeMonoPrimRep_maybe, runtimeRepMonoPrimRep_maybe. - Replace orValid with a simpler check - Use splitAtList in applyTysX - Remove calls to extra_clean in the testsuite; it does not do anything.

* testsuite: Remove reqlib modifierMatthew Pickering2021-12-2239-2617/+1
| | | | | | | | | | | | | | | | | | | | The reqlib modifer was supposed to indicate that a test needed a certain library in order to work. If the library happened to be installed then the test would run as normal. However, CI has never run these tests as the packages have not been installed and we don't want out tests to depend on things which might get externally broken by updating the compiler. The new strategy is to run these tests in head.hackage, where the tests have been cabalised as well as possible. Some tests couldn't be transferred into the normal style testsuite but it's better than never running any of the reqlib tests. https://gitlab.haskell.org/ghc/head.hackage/-/merge_requests/169 A few submodules also had reqlib tests and have been updated to remove it. Closes #16264 #20032 #17764 #16561
* Make Word64 use Word64# on every architectureSylvain Henry2021-11-061-17/+0

* Remove target dependent CPP for Word64/Int64 (#11470)Sylvain Henry2021-11-061-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | | Primops types were dependent on the target word-size at *compiler* compilation time. It's an issue for multi-target as GHC may not have the correct primops types for the target. This patch fixes some primops types: if they take or return fixed 64-bit values they now always use `Int64#/Word64#`, even on 64-bit architectures (where they used `Int#/Word#` before). Users of these primops may now need to convert from Int64#/Word64# to Int#/Word# (a no-op at runtime). This is a stripped down version of !3658 which goes the all way of changing the underlying primitive types of Word64/Int64. This is left for future work. T12545 allocations increase ~4% on some CI platforms and decrease ~3% on AArch64. Metric Increase: T12545 Metric Decrease: T12545

* Include time.h in conc059_c (#19431)Sebastian Graf2021-02-271-0/+2
| | | | | | | The test probably could have used `usleep` from `unistd.h` instead, but this seemed like the simplest solution. Fixes #19431.
* testsuite: Mark foreignInterruptible as fragile in GHCiBen Gamari2021-02-221-0/+1
| | | | | As noted in #18391, foreignInterruptible fails pretty regularly under GHCi.
* testsuite: Increase delay in conc059Ben Gamari2021-01-093-26/+37
| | | | | | | | | | | | As noted in #19179, conc059 can sometimes fail due to too short of a delay in the its Haskell threads. Address this by increasing the delay by an order of magnitude to 5 seconds. While I'm in town I refactored the test to eliminate a great deal of unnecessary platform dependence, eliminate use of the deprecated usleep, and properly handle interruption by signals. Fixes #19179.

* | Naming, value types and tests for Addr# atomicsViktor Dukhovni2020-11-052-11/+70
|/ | | | | | | | | | | | | | | The atomic Exchange and CAS operations on integral types are updated to take and return more natural `Word#` rather than `Int#` values. These are bit-block not arithmetic operations, and the sign bit plays no special role. Standardises the names to `atomic<OpType><ValType>Addr#`, where `OpType` is one of `Cas` or `Exchange` and `ValType` is presently either `Word` or `Addr`. Eventually, variants for `Word32` and `Word64` can and should be added, once #11953 and related issues (e.g. #13825) are resolved. Adds tests for `Addr#` CAS that mirror existing tests for `MutableByteArray#`.
* testsuite: Add missing #include on <stdlib.h>Ben Gamari2020-10-151-0/+1

| | | | | | | | | | | | | | | | Simon realised that the simple language composed of let bindings, bang patterns and flat constructor patterns is enough to capture the semantics of the source pattern language that are important for pattern-match checking. Well, given that the Oracle is smart enough to connect the dots in this less informationally dense form, which it is now. So we transform `translatePat` to return a list of `PmGrd`s relative to an incoming match variable. `pmCheck` then trivially translates each of the `PmGrd`s into constraints that the oracle understands. Since we pass in the match variable, we incidentally fix #15884 (coverage checks for view patterns) through an interaction with !1746.
* testsuite: Mark hs_try_putmvar003 as fragile in threaded1Ben Gamari2019-09-271-1/+2
| | | | | Due to #16361. Note that I'm leaving out threaded2 since it's not clear whether the single crash in that way was due to other causes.
* testsuite: Mark threadstatus-9333 as fragile in profthreadedBen Gamari2019-09-241-1/+1
| | | | Due to #16555.
* Expunge #ifdef and #ifndef from the codebaseJohn Ericson2019-07-145-5/+5
| | | | | | | | These are unexploded minds as far as the linter is concerned. I don't want to hit in my MRs by mistake! I did this with `sed`, and then rolled back some changes in the docs, config.guess, and the linter itself.
* testsuite: Mark T5611 and T5611a as fragileBen Gamari2019-06-261-2/+2
|
* testsuite: Add T5611aBen Gamari2019-06-265-4/+42
| | | | This is the same as T5611 but with an unsafe call to sleep.
* testsuite: Use safe FFI call in T5611Ben Gamari2019-06-261-3/+3
| | | | | The original issue, #5611, was concerned with safe calls. However, the test inexplicably used an unsafe call. Fix this.
* testsuite: Mark T5611 as broken in ghci wayBen Gamari2019-06-221-1/+4
| | | | As described in #16845.
* testsuite: Flush conc059's printf bufferBen Gamari2019-06-162-1/+2
| | | | | Otherwise it the order out the Haskell and C output will be system-dependent.
* testsuite: Add assertions that way lists are in fact listsBen Gamari2019-06-151-1/+1
| | | | | | Previously there were a few cases where operations like `omit_ways` were incorrectly passed a single way (e.g. `omit_ways('threaded2')`). This won't work as the author expected.
* testsuite: Introduce concurrent_ways setBen Gamari2019-06-151-5/+5
| | | | | | Previously we just tested for the threaded2 when determining whether to skip tests which are fragile under concurrent execution. However, this isn't the only way which is concurrent.
* testsuite: Mark threadstatus-T9333 as fragile in ghci wayBen Gamari2019-06-121-1/+1
| | | | As noted in #16555.
* testsuite: Fix omit_ways usageBen Gamari2019-06-121-1/+1
| | | | omit_ways expects a list but this was broken in several cases.
* testsuite: Mark concprog001 as fragileBen Gamari2019-05-031-0/+1
| | | Due to #16604.
