- add AlignedAllocator - an STL allocator that returns
cache-line-aligned objects (required to avoid RFOs when threads write to
various independent items in a container)
- bits: bit_mask can now be used for N=0..numBits (works around
full-word-shifts-are-undefined issue)
- precompiled.h: remove scoped_ptr, add function-related stuff from TR1
- numa:
. add numa_IsMemoryInterleaved
. numa_Allocate is now able to allocate large pages as well (reduces
TLB misses)
- os_cpu: interface change to support 32-bit apps running on WoW64
systems with > 4 GB of memory
- topology: use new x86_x64_EnumerateCaches API; fix detection of cache
ID
- x86_x64: provide the means of enumerating all caches returned by CPUID
and detect L1 cache size
This was SVN commit r6004.
fix documentation of ceil_log2 relating to input=0
remove os_cpu_SetThreadAffinity (redundant)
wcpu: make max # processors available via os_cpu.h; remove warning if
process affinity is restricted
This was SVN commit r5951.
this snowballed into a massive search+destroy of the hodgepodge of
mostly equivalent types we had in use (int, uint, unsigned, unsigned
int, i32, u32, ulong, uintN).
it is more efficient to use 64-bit types in 64-bit mode, so the
preferred default is size_t (for anything remotely resembling a size or
index). tile coordinates are ssize_t to allow more efficient conversion
to/from floating point. flags are int because we almost never need more
than 15 distinct bits, bit test/set is not slower and int is fastest to
type. finally, some data that is pretty much directly passed to OpenGL
is now typed accordingly.
after several hours, the code now requires fewer casts and less
guesswork.
other changes:
- unit and player IDs now have an "invalid id" constant in the
respective class to avoid casting and -1
- fix some endian/64-bit bugs in the map (un)packing. added a
convenience function to write/read a size_t.
- ia32: change CPUID interface to allow passing in ecx (required for
cache topology detection, which I need at work). remove some unneeded
functions from asm, replace with intrinsics where possible.
This was SVN commit r5942.
- Networking no longer tries to use IPV6, ignoring the family type of
CSocketAddr. This address will be replaced when we switch to ENet
anyway.
- The name of the Atlas semaphore now also includes a timestamp, since
the RNG generated the same sequence of names for multiple runs of the
game, causing problems if the games crashed and leaked semaphores, and
making debugging painful.
- get_executable_name now also works if the game is within an app bundle
(useful for packaging it more nicely later on, and since wxWidgets
expects us to be in an app bundle).
This was SVN commit r5407.
refactored sysdep code:
- avoid many #if OS_xxx.
- remove bsd.cpp, merge its contents with osx
- move linux-specific parts of unix/ into linux/
This was SVN commit r5363.
