# FIXME(riscv64-android):
# Before riscv64 introduced into Chromium, every 64-bit ARCH enables its own 32-bit support by default.
# But for RISCV, Android announced only pure 64-bit would be supported.
# So for riscv64, to skip the legacy check logic for its 32-bit ABI, skip_secondary_abi_for_cq is enabled by default.
# Meanwhile, android_static_analysis="off" is mandatory to guarantee disable_android_lint is true to pass gn build.
# For detailed analysis, please refer to https://github.com/aosp-riscv/chromium/issues/5#issuecomment-1486249579.
