# Description: Fix build on non-Android ARM Linux builds without NEON.
2
# - The common.gypi change allows us to disable NEON runtime detection with
3
# (arm_neon==0 and arm_neon_optional==0) builds
4
# - The sinc_resampler.cc changes add support for a mode where there is no
6
# - The isacfix.gypi changes fix the isac_neon target to not assume that
7
# arm_version==7 means there is NEON support. This prevents a problem where
8
# various lookup tables are defined twice (causing a link failure) with
9
# (arm_neon==0 and arm_neon_optional==0 and arm_version==7) builds - once
10
# in transform_neon.S (which shouldn't be built) and also in
11
# transform_tables.c - with the latter being ifdef'd in correctly only when
12
# both WEBRTC_ARCH_ARM_NEON and WEBRTC_DETECT_ARM_NEON aren't defined
