David Chisnall d0fefb8641 Don't always refer to the global pagemap. 
If you're creating a new allocator and the pagemap comes from a library
that exports the pagemap accessor function but not the pagemap symbol,
you need to be able to replace this.

David Chisnall 607573bb28 Add missing #pragma once to pal_consts.h 
If you're defining a new PAL then you need to include this file twice.

David Chisnall a93f43fd2f Add some type safety to other pagemap accesses. 
Introduce a descriptor for the pagemap config and check that the source
descriptor is compatible with the destination type.

David Chisnall 869b22b422 Sort test order so that perf tests start first. 
These take longer, so we want to start them earlier and let the shorter
tests fill in the gaps in scheduling.

David Chisnall 25c365682e Pipeline names can't contain spaces. 2019-02-25 16:33:57 +00:00
David Chisnall 11ccf365d3 Move LD_PRELOAD to a separate test. 
The Linux Debug build is currently one of the slowest two, pull out one
phase of it that is independent and allow it to run in parallel with the
other tests.
 2019-02-25 16:33:57 +00:00
David Chisnall ef50a0282b Attempt to make CI faster. 
- Don't run an expensive functionality test in debug builds.
- Don't run the different cache configurations (they're probably going
  away soon because they help only in synthetic benchmarks).

David Chisnall 45a31e75d1 Add some comments. 2019-02-25 12:54:16 +00:00
David Chisnall e371edf11e Attempt at an Apple PAL. 
Totally untested, but now we have macOS CI we can test there...
 2019-02-25 12:54:16 +00:00
David Chisnall aab4de7bc9 First attempt at adding macOS to CI. 2019-02-25 12:54:16 +00:00
David Chisnall 6a5359b177 Pull aligned allocation out of the PAL. 
The PAL can now advertise that it supports aligned allocation.  If it
does not, then the memory provider will do the alignment for it.

This change still leaves the PAL responsible for systematic testing, but
it should now be much easier to lift that out.

David Chisnall d6e89b7c60 Fix Matt's code review comments. 2019-02-25 11:27:53 +00:00
David Chisnall 01bd77b356 Remove some ugly templated things. 
Replace them with some very simple constexpr things.  This is what the
code used to look like, but it appears that I fundamentally
misunderstood why it didn't work.  This version should be a lot more
maintainable.
 2019-02-25 11:27:53 +00:00
David Chisnall f178028640 [NFC] clang-format again. 
It appears that clang-format 6 (which CI uses) removes a newline that
clang-format 7 doesn't, but will also not add.  The new formatting
should keep 6 and 7 both happy.

David Chisnall 5adba34d60 Make clang happy. 2019-02-25 11:27:53 +00:00
David Chisnall a24e6270cc Provide a generic PAL feature detection mechanism. 
We can support up to 64 optional features, currently only one is used.
 2019-02-25 11:27:53 +00:00
David Chisnall 80630a359f Clean up interface to the low memory notifications. 
- Rename MemoryProviderState to PAL to reflect what is now is.
 - Hide calls to the PAL's low memory functions behind something that
   returns a default value if they're not implemented.

David Chisnall f6349092c9 Remove debugging define. 
This was enabled so CI would run it.  It probably should be enabled for
some testing, but via CMake, not like this.
 2019-02-25 11:27:53 +00:00
David Chisnall 6af4c97726 Explicitly qualify a method. 
Either clang or cl has a bug: cl accepts the unqualified (inherited)
method name, clang rejects it.  Both accept the qualified name.

David Chisnall 66cec23b23 Initial cut at a lazy decommit strategy. 
This does not deallocate memory until the OS tells us that we are short
on memory, then tries to decommit all of the cached chunks (except for
the first page, used for the linked lists).

Nowhere near enough testing to commit to master yet!

David Chisnall 4830bd4021 Check for an SDK version before enabling VirtualAlloc2. 
This is mainly to keep the CI system happy: it's using an old SDK
because the new version of cl.exe doesn't work with cmake...
 2019-02-20 17:36:39 +01:00
David Chisnall 2ee3ba59ee Use VirtualAlloc2 on Windows. 
The newer API (Windows 10 and newer) allows the allocator to ask for
strongly aligned memory.

This is enabled only if the `WINVER` macro is set to target Windows 10
or newer.  There is now a CMake option to target older versions of
Windows, so we can test both code paths.

The Azure Pipelines config now includes a test of the compatibility
version.  This runs only the release build, because it's mainly there as
a sanity check - 99% of the code is the same as the default Windows
config.

Paul Liétar 66400af419 Add a cache-friendly version of the tests. 
This only tests CACHE_FRIENDLY_OFFSET=64, which is probably what we'll be using in the end.
 2019-02-18 14:51:04 +00:00
Paul Liétar 4ac3421487 Place the next pointer at a different place on every object. 
This limits the collision in cache buckets, especially for larger objects.
 2019-02-18 14:22:50 +00:00
David Chisnall c47eed1922 Tweaks to end bounds checking. 
Introduce a `OnePastEnd` option for the pointer immediately after the
end of the allocation.  This simplifies some of the logic in callers,
where they wants to say 'is base + length safe to use?'.

Also restructure some of the other logic somewhat.
