| | | | | | | | | | Throw a slightly more informative error on failure. Motivated by the errors seen in !2160.
| * rts: Consolidate spinlock implementationBen Gamari2019-11-231-47/+13
| | | | | | | | | | Previously we had two distinct implementations: one with spinlock profiling and another without. This seems like needless duplication.

| * Prevent -optc arguments from being duplicated in reverse order (#17471)Ryan Scott2019-11-235-3/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts a part of commit 7bc5d6c6578ab9d60a83b81c7cc14819afef32ba that causes all arguments to `-optc` (and `-optcxx`) to be passed twice to the C/C++ compiler, once in reverse order and then again in the correct order. While passing duplicate arguments is usually harmless it can cause breakage in this pattern, which is employed by Hackage libraries in the wild: ``` ghc Foo.hs foo.c -optc-D -optcFOO ``` As `FOO -D -D FOO` will cause compilers to error. Fixes #17471.
| * Make CorePrep.tryEtaReducePrep and CoreUtils.tryEtaReduce line upMatheus Magalhães de Alcantara2019-11-232-20/+10
| | | | | | | | | | | | | | Simon PJ says he prefers this fix to #17429 over banning eta-reduction for jumps entirely. Sure enough, this also works. Test case: simplCore/should_compile/T17429.hs
| * Take care to not eta-reduce jumps in CorePrepMatheus Magalhães de Alcantara2019-11-233-2/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | CorePrep already had a check to prevent it from eta-reducing Ids that respond true to hasNoBinding (foreign calls, constructors for unboxed sums and products, and Ids with compulsory unfoldings). It did not, however, consider join points as ids that 'must be saturated'. Checking whether the Id responds True to 'isJoinId' should prevent CorePrep from turning saturated jumps like the following (from #17429) into undersaturated ones: (\ eta_XP -> join { mapped_s1vo _ = lvl_s1vs } in jump mapped_s1vo eta_XP)
| * rts: Expose interface for configuring EventLogWritersBen Gamari2019-11-2311-50/+195
| | | | | | | | | | | | This exposes a set of interfaces from the GHC API for configuring EventLogWriters. These can be used by consumers like [ghc-eventlog-socket](https://github.com/bgamari/ghc-eventlog-socket).

* | Use pointer equality in Eq/Ord for ThreadIdRoland Zumkeller2019-11-194-17/+29
| | | | | | | | | | | | | | | | | | | | Changes (==) to use only pointer equality. This is safe because two threads are the same iff they have the same id. Changes `compare` to check pointer equality first and fall back on ids only in case of inequality. See discussion in #16761.

* | nonmoving: Drop redundant write barrier on stack underflowBen Gamari2019-11-191-10/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | Previously we would push stack-carried return values to the new stack on a stack overflow. While the precise reasoning for this barrier is unfortunately lost to history, in hindsight I suspect it was prompted by a missing barrier elsewhere (that has been since fixed). Moreover, there the redundant barrier is actively harmful: the stack may contain non-pointer values; blindly pushing these to the mark queue will result in a crash. This is precisely what happened in the `stack003` test. However, because of a (now fixed) deficiency in the test this crash did not trigger on amd64.
* | testsuite: Increase width of stack003 testBen Gamari2019-11-191-5/+11
| | | | | | | | | | | | Previously the returned tuple seemed to fit in registers on amd64. This meant that non-moving collector bug would cause the test to fail on i386 yet not amd64.
* | nonmoving: Fix handling on large object marking on 32-bitBen Gamari2019-11-191-4/+7
| | | | | | | | | | | | | | | | | | Previously we would reset the pointer pointing to the object to be marked to the beginning of the block when marking a large object. This did no harm on 64-bit but on 32-bit it broke, e.g. `arr020`, since we align pinned ByteArray allocations such that the payload is 8 byte-aligned. This means that the object might not begin at the beginning of the block.,
* | nonmoving: Rework mark queue representationBen Gamari2019-11-192-23/+18
| | | | | | | | | | The previous representation needlessly limited the array length to 16-bits on 32-bit platforms.
* | nonmoving: Fix incorrect masking in mark queue type testBen Gamari2019-11-191-2/+2
| | | | | | | | | | | | We were using TAG_BITS instead of TAG_MASK. This happened to work on 64-bit platforms where TAG_BITS==3 since we only use tag values 0 and 3. However, this broken on 32-bit platforms where TAG_BITS==2.
* | nonmoving: Use correct info table pointer accessorBen Gamari2019-11-192-19/+7
| | | | | | | | | | | | | | | | | | | | | | Previously we used INFO_PTR_TO_STRUCT instead of THUNK_INFO_PTR_TO_STRUCT when looking at a thunk. These two happen to be equivalent on 64-bit architectures due to alignment considerations however they are different on 32-bit platforms. This lead to #17487. To fix this we also employ a small optimization: there is only one thunk of type WHITEHOLE (namely stg_WHITEHOLE_info). Consequently, we can just use a plain pointer comparison instead of testing against info->type.
* | rts: Add missing include of SymbolExtras.hBen Gamari2019-11-191-0/+1
| | | | | | | | This broke the Windows build.
* | Properly account for libdw paths in make build systemBen Gamari2019-11-194-3/+14
| | | | | | | | Should finally fix #17255.
* | Packages.hs: use O(n*log(n)) ordNub instead of O(n*n) nubÖmer Sinan Ağacan2019-11-191-6/+6
| | | | | | | | | | As reported in #8173 in some environments package lists can get quite long, so we use more efficient ordNub instead of nub on package lists.
* | Enable USE_PTHREAD_FOR_ITIMER also on FreeBSDViktor Dukhovni2019-11-191-0/+3
| | | | | | | | | | | | | | | | | | | | | | If using a pthread instead of a timer signal is more reliable, and has no known drawbacks, then FreeBSD is also capable of supporting this mode of operation (tested on FreeBSD 12 with GHC 8.8.1, but no reason why it would not also work on FreeBSD 11 or GHC 8.6). Proposed by Kevin Zhang in: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=241849
* | Give seq a more precise type and remove magicBen Gamari2019-11-1911-170/+142
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | `GHC.Prim.seq` previously had the rather plain type: seq :: forall a b. a -> b -> b However, it also had a special typing rule to applications where `b` is not of kind `Type`. Issue #17440 noted that levity polymorphism allows us to rather give it the more precise type: seq :: forall (r :: RuntimeRep) a (b :: TYPE r). a -> b -> b This allows us to remove the special typing rule that we previously required to allow applications on unlifted arguments. T9404 contains a non-Type application of `seq` which should verify that this works as expected. Closes #17440.
* | desugar: Drop stale Note [Matching seqId]Ben Gamari2019-11-191-6/+0

* | testsuite: Skip T17414 on LinuxBen Gamari2019-11-171-0/+4
| | | | | | | | | | | | It is typical for $TMP to be a small tmpfson Linux. This test will fail in such cases since we must create a file larger than the filesystem. See #17459.
