Some of the tests are quite heavy CPU users and may benefit from
using multiple CPU cores, so the programs from 'test' directory
are now built with OpenMP support. OpenMP is easy to use, portable
and also takes care of making a decision about how many threads
to spawn.

It is apparently broken. See this:
http://mingw-users.1079350.n2.nabble.com/gcc-4-4-multi-threaded-exception-handling-thread-specifier-not-working-td3440749.html
We'll need to support thread local storage on MinGW32 some other way.

This should be the last step in providing full armv4t compatibility
with CPU features runtime autodetection in pixman.
|
|
This can be used to override the architecture recorded in the EABI object
attribute section. We set a minimum arch to 'armv4'. Binutils documentation
recommends to use this directive with the code performing runtime detection
of CPU features.
Additionally NEON/VFP EABI attributes are suppressed. And the instruction
set to use is explicitly set to '.arm'.
Configure test for NEON support is also updated to include a bunch of
these new directives (if any of these is unsupported by the assembler,
it is better to fail configure test than to fail library build).
All these changes are required to fix SIGILL problem on armv4t, reported in
http://lists.freedesktop.org/archives/pixman/2010-March/000123.html

OS X does not support __thread, so we have to check for it before
using it. It does however support pthread_get/setspecific(), so if we
don't have __thread, check if those are available.

GNU assembler and its macro preprocessor is now used to generate
NEON optimized functions from a common template. This automatically
takes care of nuisances like ensuring optimal alignment, dealing with
leading/trailing pixels, doing prefetch, etc.
Implementations for a lot of compositing functions are also added,
but not enabled.
|
|
Instead of mucking around with CFLAGS in configure.ac, preventing
users from setting their own CFLAGS, just define the
PIXMAN_USE_INTERNAL_API and PIXMAN_DISABLE_DEPRECATED in
pixman-private.h

Speed up bilinear interpolation by processing more than one component
at a time on 64 bit architectures, and by precomputing the dist{ixiy}
products on 32 bit architectures.
Previously bilinear interpolation for one pixel would take 24
multiplications. With this improvement it takes 12 on 64 bit, and 20
on 32 bit.
This is a small but consistent speedup on the swfdec-youtube
benchmark:
[ # ] backend test min(s) median(s) stddev. count
Before:
[ 0] image swfdec-youtube 18.010 18.020 0.09% 4/5
After:
[ 0] image swfdec-youtube 17.488 17.584 0.22% 5/6

As an interim measure, replace AM_INIT_AUTOMAKE([dist-bzip2]) with
AM_INIT_AUTOMAKE([foreign dist-bzip2]). This will prevent the generation
of the INSTALL file. It is also part of the 24206 solution.

These cannot sanely be used by applications since they may change in
new versions.
|

Compile warnings are being lost in the sea of noise. Automake-1.11 finally
introduced AM_SILENT_RULES to suppress the echoing of the compile line for
every object. Enable this to bring sanity to the pixman build.

CFLAGS are always appended to the end of gcc options when compiling
sources in autotools based projects. Configure tests should do the
same. Otherwise build fails on PPC when using CFLAGS="-O2 -mno-altivec"
for example. Similar problem affects ARM.
|
|
Autoconf's AC_PROG_CC sets the default CFLAGS to -O2 -g for
gcc and -g for every other compiler. This patch defaults
CFLAGS to the equivalent -O -g when we're using Sun Studio's cc
if the user or site admin hasn't already set CFLAGS.

Fall back to malloc() in blitters-test.c if we don't.

The pld instruction used in the NEON assembler code is only available
for ARMv5e and >= ARMv6.
Set -mcpu=cortex-a8 when compiling the source file (similar to what is
already done for the SIMD build).
|
|
If we're trying to use the GNU linker on Solaris we shouldn't use
our solaris-hwcap.mapfile since it doesn't grok the mapfile format.

Option -mcpu has higher priority than -march with the current versions
of gcc and that's why it is better to use. There is no particular
reason why 'arm1136j-s' is used in this patch, it could be any armv6
compatible core.
