Johannes Kauffmann e09bec51c0 cpu: properly indent x86 defines 
To match the other architecture subsections.

Rémi Denis-Courmont cb303e77f4 cpu: define VLC_ALTIVEC attribute macro 
Like on x86 (e.g. VLC_SSE), this macro enables the use of AltiVec for
just a given function. Thus the other functions in the same C module
can be compiled without AltiVec and run on non-AltiVec processors.

Rémi Denis-Courmont 2188dd740f cpu: compile-time RISC-V "V" V.E. detection 
This detects compiler support for the RISC-V "V" Vector Extension if it
enabled in the compiler flags (or compiler machine definition).

Rémi Denis-Courmont 813f70062c linux/cpu: run-time detect AdvSIMD on AArch64 
This only assumes NEON is available on AArch64 if it is actually
enabled in the compiler settings (or rather, not explicitly disabled).
Otherwise, perform regular run-time detection.
 2018-12-17 19:55:43 +02:00
Rémi Denis-Courmont edf6ff7544 cpu: generic support for ARM SVE 
This adds generic support for the AArch64 Scalable Vector Extension.

Rémi Denis-Courmont 97d669a8c7 Remove ifdefs for GCC version below 4.4 
According to INSTALL, we require GCC 4.8 already.
 2017-02-25 15:37:38 +02:00
Janne Grunau 8df6a21f8a deinterlace: arm64 NEON merge asm 
Approximately factor 2 faster.

Also adds build system support / cpu "detection" for arm64 neon.
Advanced SIMD (neon) is mandatory for general purpose ARMv8-a CPU so the
CPU feature detection is a constant 1.

Rémi Denis-Courmont cf5a82224a ARM: detect VFP floating point unit 
This sets HAVE_FPU correctly on ARM targets if VFP instructions are
enabled. Note that __VFP_FP__ implies the use of the VFP floating point
format, not the availability of the VFP instructions. Thus software
floating emulation __SOFTFP__ (i.e. gcc -mfloat-abi=soft) is excluded
explicitly.

 - by e-mail,
 - by vote at the VideoLAN Dev Days 2011,
 - on the license website,
 - in a contract, oral or written.
No objection was raised, so far.

It is possible, that some minor piece of code was badly tracked, for
some reasons (SVN, mainly) or that some small developers did not answer.
However, as an "œuvre collective", defined as in "CPI 113-2 alinéa 3",
and seeing "Cour. Cass. 17 Mai 1978", and seeing that the editor and
the very vast majority of developers have agreed (> 99.99% of the code,
> 99% of developers), we are fine here.

Rémi Denis-Courmont 497f9affad vlc_GetCPUCount(): move to thread subsystem (cosmetic) 2011-06-29 21:00:34 +03:00
Rémi Denis-Courmont 6a45dac72f Alias vlc_memset() to memset() 
This saves two function calls per memset() since there are no optimized
implementations of memset() at all.

Rémi Denis-Courmont 6f258887aa Replace VLC_EXPORT macro with a simple prefix, VLC_API 
This should help Doxygen parse VLC headers, and generally makes headers
easier to read. LibVLC already uses a similar approach.
