This directory contains tools and scripts to test libtv image
manipulation routines.
File overview
-------------
clear_image/clear_image.c/pixel.h/clear_image-mmx|sse.sh
Tests all implementations of the tv_clear_image() function.
Run by make check for all compiled implementations. May use an
emulator if we cross-compile or the CPU lacks the required feature.
cpudt/cpudt.c
CPU feature detection. Use like "if cpudt mmx; then ..."
Possible features are mmx, 3dnow, sse, sse2, altivec and
others. Used by simd-emu.sh.
guard1.c/guard2.c/guard.h
Miniature version of efence, to check for buffer overflows
during tests, and two test for mini-efence itself.
memcpy/memcpy.c/memcpy-mmx|sse.sh
Tests all implementations of the tv_memcpy() function.
Run by make check for all compiled implementations. May use an
emulator if we cross-compile or the CPU lacks the required feature.
simd-emu.sh
Runs a test program using an emulator, currently qemu, if our CPU
does not support the required feature. Used by various scripts.
simd/simd.c/simd-mmx|3dnow|sse|sse2|altivec.sh
Tests if the libtv/simd.h macros do what they are supposed to.
Run by make check for all compilable implementations. May use an
emulator if we cross-compile or the CPU lacks the required feature.
