# Enabling this option makes clang compile to an intermediate
# representation ("bitcode"), and not to native code. This is preferred
# when including WebRTC in the apps that will be sent to Apple's App Store
# and mandatory for the apps that run on watchOS or tvOS.
# The option only works when building with Xcode (use_xcode_clang = true).
# Mimicking how Xcode handles it, the production builds (is_debug = false)
# get real bitcode sections added, while the debug builds (is_debug = true)
# only get bitcode-section "markers" added in them.
# NOTE: This option is ignored when building versions for the iOS simulator,
# where a part of libvpx is compiled from the assembly code written using
# Intel assembly syntax; Yasm / Nasm do not support emitting bitcode parts.
# That is not a limitation for now as Xcode mandates the presence of bitcode
# only when building bitcode-enabled projects for real devices (ARM CPUs).
