4:19 PM Changeset in process [9998026]encodingghc-7.2ghc-7.4ghc-7.6ghc-7.8 by Simon Marlow <marlowsd@…>
Avoid vfork() bear traps We can't call setIOManagerPipe() in the vfork() child, because the change will be reflected in the parent too. Add a large warning to that effect. I tried changing vfork() to fork(), but it seems that this leads to a different problem: the fork() sometimes takes so long that it gets repeatedly interrupted by the timer signal and never makes progress. I could disable the timer for a while, but decided to back off and fix the vfork() version instead.

Fix a bug which sometimes caused extra major GCs to be performed A long-running GC would cause the timer signal to declare the system to be idle, which would cause a major GC immediately following the current GC. This only happened with +RTS -N2 or greater.

Redesign 64-bit HEAP_ALLOCED (FIX #2934 at the same time) After much experimentation, I've found a formulation for HEAP_ALLOCED that (a) improves performance, and (b) doesn't have any race conditions when used concurrently. GC performance on x86_64 should be improved slightly. See extensive comments in MBlock.h for the details.

Partial fix for #2917 - add newAlignedPinnedByteArray# for allocating pinned BAs with arbitrary alignment - the old newPinnedByteArray# now aligns to 16 bytes Foreign.alloca will use newAlignedPinnedByteArray#, and so might end up wasting less space than before (we used to align to 8 by default). Foreign.allocaBytes and Foreign.mallocForeignPtrBytes will get 16-byte aligned memory, which is enough to avoid problems with SSE instructions on x86, for example. There was a bug in the old newPinnedByteArray#: it aligned to 8 bytes, but would have failed if the header was not a multiple of 8 (fortunately it always was, even with profiling). Also we occasionally wasted some space unnecessarily due to alignment in allocatePinned(). I haven't done anything about Foreign.malloc/mallocBytes, which will give you the same alignment guarantees as malloc() (8 bytes on Linux/x86 here).

Partial fix for #2917 - add newAlignedPinnedByteArray# for allocating pinned BAs with arbitrary alignment - the old newPinnedByteArray# now aligns to 16 bytes Foreign.alloca will use newAlignedPinnedByteArray#, and so might end up wasting less space than before (we used to align to 8 by default). Foreign.allocaBytes and Foreign.mallocForeignPtrBytes will get 16-byte aligned memory, which is enough to avoid problems with SSE instructions on x86, for example. There was a bug in the old newPinnedByteArray#: it aligned to 8 bytes, but would have failed if the header was not a multiple of 8 (fortunately it always was, even with profiling). Also we occasionally wasted some space unnecessarily due to alignment in allocatePinned(). I haven't done anything about Foreign.malloc/mallocBytes, which will give you the same alignment guarantees as malloc() (8 bytes on Linux/x86 here).

On OS X/x86, tell gcc to generate instructions for i686. Fixes trac #2983. By default, gcc on OS X will generate SSE instructions, which need things 16-byte aligned, but we don't 16-byte align things. Thus drop back to generic i686 compatibility.
