      Easy way to defer type errors (implements #8353) · 5d48e67f
      triple authored
      Added load! and reload! commands, effectively setting
      "-fdefer-type-errors" before loading a file and
      unsetting it after loading if it has not been set before.

      Testsuite: add -ignore-dot-ghci to some tests · 124f3999
      thomie authored
      Since T10408A and T10408B would become the same now, delete T10408A and
      rename T10408B to T10408. The test without -ignore-dot-ghci (T10408A)
      didn't add anything (#10408).

      Support MO_{Add,Sub}IntC and MO_Add2 in the LLVM backend · b1d1c652
      Michal Terepeta authored
      This includes:
      
      - Adding new LlvmType called LMStructP that represents an unpacked
        struct (this is necessary since LLVM's instructions the
        llvm.sadd.with.overflow.* return an unpacked struct).
      
      - Modifications to LlvmCodeGen.CodeGen to generate the LLVM
        instructions for the primops.
      
      - Modifications to StgCmmPrim to actually use those three instructions
        if we use the LLVM backend (so far they were only used for NCG).

      Implement PowerPC 64-bit native code backend for Linux · d3c1dda6
      Peter Trommler authored
      Extend the PowerPC 32-bit native code generator for "64-bit
      PowerPC ELF Application Binary Interface Supplement 1.9" by
      Ian Lance Taylor and "Power Architecture 64-Bit ELF V2 ABI Specification --
      OpenPOWER ABI for Linux Supplement" by IBM.
      The latter ABI is mainly used on POWER7/7+ and POWER8
      Linux systems running in little-endian mode. The code generator
      supports both static and dynamic linking. PowerPC 64-bit
      code for ELF ABI 1.9 and 2 is mostly position independent
      anyway, and thus so is all the code emitted by the code
      generator. In other words, -fPIC does not make a difference.
      
      rts/stg/SMP.h support is implemented.
      
      Following the spirit of the introductory comment in
      PPC/CodeGen.hs, the rest of the code is a straightforward
      extension of the 32-bit implementation.
      
      Limitations:
      * Code is generated only in the medium code model, which
        is also gcc's default
      * Local symbols are not accessed directly, which seems to
        also be the case for 32-bit
      * LLVM does not work, but this does not work on 32-bit either
      * Must use the system runtime linker in GHCi, because the
        GHC linker for "static" object files (rts/Linker.c) for
        PPC 64-bit is not implemented. The system runtime
        (dynamic) linker works.
      * The handling of the system stack (register 1) is not ELF-
        compliant so stack traces break. Instead of allocating a new
        stack frame, spill code should use the "official" spill area
        in the current stack frame and deallocation code should restore
        the back chain
      * DWARF support is missing
      
      Fixes #9863

      Update performance numbers due to #10482 · 9b5df2a4
      Joachim Breitner authored
      The fix in 0b7e538a has regressed these benchmarks. I have recentered
      them rather than marking them as broken(10482), because nobody
      systematically watches the broken test cases, and we want to catch
      future regressions (or improvements!). #10482 is currently still open,
      presumably because this needs investigating.

      Simon Peyton Jones authored
      GHC can't yest build a TypeRep for a type involving kind variables.
      (We await kinds = types for that.)  But the error message was terrible,
      as fixing #10524 reminded me.
      
      This improves it a lot.

      Improve CPR behavior for strict constructors · 0696fc6d
      Simon Peyton Jones authored
      When working on Trac #10482 I noticed that we could give constructor
      arguments the CPR property if they are use strictly.
      
      This is documented carefully in
          Note [CPR in a product case alternative]
      and also
          Note [Initial CPR for strict binders]
      
      There are a bunch of intersting examples in
          Note [CPR examples]
      which I have added to the test suite as T10482a.
      
      I also added a test for #10482 itself.

      Fix deadlock (#10545) · 111ba4be
      Simon Marlow authored
      yieldCapability() was not prepared to be called by a Task that is not
      either a worker or a bound Task.  This could happen if we ended up in
      yieldCapability via this call stack:
      
      performGC()
      scheduleDoGC()
      requestSync()
      yieldCapability()
      
      and there were a few other ways this could happen via requestSync.
      The fix is to handle this case in yieldCapability(): when the Task is
      not a worker or a bound Task, we put it on the returning_workers
      queue, where it will be woken up again.
      
      Summary of changes:
      
      * `yieldCapability`: factored out subroutine waitForWorkerCapability`
      * `waitForReturnCapability` renamed to `waitForCapability`, and
        factored out subroutine `waitForReturnCapability`
      * `releaseCapabilityAndQueue` worker renamed to `enqueueWorker`, does
        not take a lock and no longer tests if `!isBoundTask()`
      * `yieldCapability` adjusted for refactorings, only change in behavior
        is when it is not a worker or bound task.
      
      Test Plan:
      * new test concurrent/should_run/performGC
      * validate
