use crate::spec::{LinkerFlavor, Target, TargetOptions, TargetResult};

// This target is for glibc Linux on ARMv7 with thumb mode enabled
// (for consistency with Android and Debian-based distributions)
// and with NEON unconditionally enabled and, therefore, with 32 FPU
// registers enabled as well. See section A2.6.2 on page A2-56 in
// https://static.docs.arm.com/ddi0406/cd/DDI0406C_d_armv7ar_arm.pdf
