David Chisnall caec12c545 Reduce the parallelism in Windows Release build tests. 
Hopefully this will stop the CI machines from running out of memory...
 2019-08-01 12:53:03 +01:00
David Chisnall d24ad45abe [NFC] clangformat. 2019-08-01 12:03:35 +01:00
David Chisnall 81a0f0aed8 [NFC] Remove one more unneeded include. 2019-08-01 11:50:35 +01:00
David Chisnall d11f09e4ec [NFC] Remove incorrect guard and some unused includes. 2019-08-01 11:50:27 +01:00
David Chisnall 896cc9cf6f [NFC] Rename some PALs to make the naming more consistent. 2019-08-01 11:44:09 +01:00
David Chisnall 2b44b6b5ea Add a NetBSD PAL. 
Currently untested, but identical to the FreeBSD one so should work...
The NetBSD man pages for `madvise` and `mmap` mention the flags that we
use.
 2019-08-01 11:41:08 +01:00
David Chisnall fd88b8464b [NFC] Separate out support for aligned allocation from the FreeBSD PAL. 
NetBSD also supports `MAP_ALIGNED()` in `mmap` (according to the man
page, at least).
 2019-08-01 11:39:26 +01:00
David Chisnall cf6fca6514 [NFC] Make the Apple PAL use the generic BSD code. 2019-08-01 11:21:32 +01:00
David Chisnall 54cbf8b2bb [NFC] Remove unused headers from OpenBSD PAL. 2019-08-01 11:21:28 +01:00
David Chisnall 0497993d23 Fix typo in OpenBSD PAL. 2019-08-01 11:20:05 +01:00
David Chisnall d257f60731 [NFC] Add missing doc comments. 2019-08-01 11:03:22 +01:00
David Chisnall 4ed15def79 [NFC] Remove some code duplication in the PALs. 
Pull out a generic POSIX PAL as a superclass for the Linux and generic
BSD PALs.  Now we have FreeBSD and Linux adding OS-specific behaviour,
OpenBSD as a named subclass of the generic BSD PAL that doesn't add any
behaviour.

I believe a NetBSD PAL should now be identical to the OpenBSD one -
patches welcome if anyone wants to test one!

Merge pull request #74 from devnexen/openbsd_support 
Basic OpenBSD backend support.

David Carlier fdae3b451f Creating base class instead used by both platforms. 2019-07-31 10:27:35 +00:00
David Carlier 6b4ff3e7ab Basic OpenBSD backend support. 
Cannot enforce alignment so we just check its correctness.

Merge pull request #73 from plietar/get_noncachable 
Use get_noncachable in malloc/new overrides.
 2019-07-17 16:13:17 +01:00
Paul Liétar b2b86565db Use get_noncachable in malloc/new overrides. 
This may return the GlobalPlaceholder, in which case the slow path will
be used, initializing the real thread local allocator.

Improved ThreadAlloc::get API
 2019-07-16 11:25:27 +01:00
David Chisnall d3f5dcefe4 Fix the libc hook. 
Friend declarations to `extern "C"` functions must have a forward
declaration with the correct signature.

Matthew Parkinson 280c2ae25c Refactor ThreadAlloc 
Made common code between the Libc and C++ based releasing of allocators
part of a parent class, which each implementation subclasses.

Merge pull request #70 from microsoft/pagemap-splice 
Add two APIs that are missing from the flat pagemap.
 2019-07-15 15:11:09 +01:00
Matthew Parkinson df1896d55f Improved ThreadAlloc::get API 
Made the API so that get always returns an initialised Alloc*.  Added
new fast path that doesn't perform checking, but can lead to very slow
behaviour if called and reused.

Adding a handle_message_queue here lead to an infinite loop.

Matthew Parkinson c6178322b0 Minor 2019-07-10 20:11:04 +01:00
Matthew Parkinson 9fd238d5fa Move remote dealloc to slow path 
It is only ever called in a tail position, so slow path means it is just
a jump, but improves the local deallocation fast path's codegen
considerably.
 2019-07-10 20:11:04 +01:00
Matthew Parkinson e240dd279a Use FlatPageMap on OS with lazy commit 
If the operating system will allocate private pages on demand for the
pagemap then use the FlatPageMap by default as it generates better code
for deallocation.

David Chisnall bc34e5abe5 Reduce parallelism on the Win8Compat CI job 
This version doesn't get to perform aligned allocations and so can
consume a lot more memory than the other modes.
 2019-07-10 11:50:20 +01:00
David Chisnall d83828c537 [NFC] Appease clang-tidy. 2019-07-10 11:22:24 +01:00
David Chisnall ccaae50dd4 Explicitly include cstdint in the AAL. 
This is not necessary with libc++ platforms because of some header
pollution, but is necessary everywhere else.
 2019-07-10 11:05:55 +01:00
David Chisnall 7eabea01d6 Add an Architecture Abstraction Layer. 
Currently, we support one architecture, but this provides a layer for
adding other architectures without adding more nested `#ifdef`s.

Fixes #42
