comment "libevas code tuning"
config BR2_PACKAGE_LIBEVAS_DISABLE_C
bool "libevas disable C code"
depends on BR2_PACKAGE_LIBEVAS_MMX || BR2_PACKAGE_LIBEVAS_SSE || BR2_PACKAGE_LIBEVAS_SSE3
help
This disables the generic C fallback code which is not required
if MMX or SSE is used instead.
config BR2_PACKAGE_LIBEVAS_MMX
bool "libevas MMX routines"
depends on BR2_i386 || BR2_x86_64
help
This enables the MMX optimized routines. this works for
Pentium, Pentium 2, Pentium 3, Pentium 4, Athlon and Duron
processors.
config BR2_PACKAGE_LIBEVAS_SSE
bool "libevas SSE routines"
depends on BR2_i386 || BR2_x86_64
help
This enables SSE optimizations available in the Pentium 3 and
4 cpus (not Athlon and Duron or Pentium 2 or Pentium cpus).
config BR2_PACKAGE_LIBEVAS_SSE3
bool "libevas SSE3 routines"
depends on BR2_i386 || BR2_x86_64
help
This enables SSE3 optimizations available in the Pentium 4 and
above cpus.
config BR2_PACKAGE_LIBEVAS_ALTIVEC
bool "libevas altivec routines"
depends on BR2_powerpc
help
This enables AltiVec optimizations available in some PowerPC cpus.
config BR2_PACKAGE_LIBEVAS_NEON
bool "libevas neon routines"
depends on BR2_arm
help
This enables NEON optimizations available in some ARM cpus.
