* interruptible() was not returning true for BlockedOnSTM (#9379)Simon Marlow2014-08-012-0/+19
| | | | | | | | | | | | | | | | | | | Summary: There's an knock-on fix in HeapStackCheck.c which is potentially scary, but I'm pretty confident is OK. See comment for details. Test Plan: I've run all the STM tests I can find, including libraries/stm/tests/stm049 with +RTS -N8 and some of the constants bumped to make it more of a stress test.

* use GHC-7.8.3's values for thread block reason (fixes #9333)Jost Berthold2014-07-283-1/+46
| | | | | | | | | | | | | | | | | | | | Summary: For now, BlockedOnMVar and BlockedOnMVarRead are not distinguished. Making the distinction would mean to change an exported datatype (API change). Code for this change is included but commented out. The patch adds a test for the threadstatus, which retrieves status BlockedOnMVar for two threads blocked on writing and reading an MVar.

* Fix test for fetchNandIntArray#Johan Tibell2014-07-231-7/+18
| | | | | The test was incorrectly testing that NAND is associative, which it isn't.
* Re-add more primops for atomic ops on byte arraysJohan Tibell2014-06-303-0/+253
| | | | | | | | | | | | | | | | | | | | | | | This is the second attempt to add this functionality. The first attempt was reverted in 950fcae46a82569e7cd1fba1637a23b419e00ecd, due to register allocator failure on x86. Given how the register allocator currently works, we don't have enough registers on x86 to support cmpxchg using complicated addressing modes. Instead we fall back to a simpler addressing mode on x86. Adds the following primops: * atomicReadIntArray# * atomicWriteIntArray# * fetchSubIntArray# * fetchOrIntArray# * fetchXorIntArray# * fetchAndIntArray# Makes these pre-existing out-of-line primops inline: * fetchAddIntArray# * casIntArray#
* Simplify .gitignore filesHerbert Valerio Riedel2014-06-281-6/+0
| | | | | | | | | It's a bit confusing to have .gitignore files spread all over the filesystem. This commit tries to consolidate those into one .gitignore file per component. Moreover, we try to describe files to be ignored which happen to have a common identifying pattern by glob patterns. Signed-off-by: Herbert Valerio Riedel <hvr@gnu.org>
* Revert "Add more primops for atomic ops on byte arrays"Johan Tibell2014-06-264-254/+0

* Revert "Per-thread allocation counters and limits"Simon Marlow2014-05-048-82/+0
| | | | | | | | Problems were found on 32-bit platforms, I'll commit again when I have a fix. This reverts the following commits: 54b31f744848da872c7c6366dea840748e01b5cf b0534f78a73f972e279eed4447a5687bd6a8308e
* Per-thread allocation counters and limitsSimon Marlow2014-05-028-0/+82
| | | | | | | | | | | | | | | | | | | | | | | This tracks the amount of memory allocation by each thread in a counter stored in the TSO. Optionally, when the counter drops below zero (it counts down), the thread can be sent an asynchronous exception: AllocationLimitExceeded. When this happens, given a small additional limit so that it can handle the exception. See documentation in GHC.Conc for more details. Allocation limits are similar to timeouts, but - timeouts use real time, not CPU time. Allocation limits do not count anything while the thread is blocked or in foreign code. - timeouts don't re-trigger if the thread catches the exception, allocation limits do. - timeouts can catch non-allocating loops, if you use -fno-omit-yields. This doesn't work for allocation limits. I couldn't measure any impact on benchmarks with these changes, even for nofib/smp.

* Deal with failures for T367, T367_letnoescape under ghciReid Barton2013-09-301-2/+2
| | | | | | | | | | These tests had a very short timeout (0.3 s). With WAY=ghci, the time ghci takes to start up and compile the test modules is counted in this timeout, and that causes the tests to fail. T367 really needs the very short timeout, so this commit disables the ghci way for T367. T367_letnoescape can handle any timeout, so I bumped up the timeout to 6 s to give ghci time to start up.

| | | | | This is much closer to how the test originally worked, so it's more likely that the test is still testing what it was testing before :-)

| | | | | | | | This allows them to give framework failures. I also had to change how setTestOpts works. Now, rather than applying the options to the directory's "default options", it just stores the options to be applied for each test (i.e. once we know the test name).
