1. correct the armv8-r fpu flag from vfpv3-d16 to fpv5-sp-d16 2. add neon support This commit updates the build script to specify the FPU type of `fpv5-sp-d16` when the processor is configured with a single-precision FPU, and `neon-fp-armv8` when the processor is configured with a double-precision + Advanced SIMD-capable FPU. Note that the `fp-armv8` FPU type is an alias for double-precision FPv5 with 32 double-precision registers (refer to the GCC `gcc/config/arm/arm-cpus.in` for more details); NEON is always specified in case of a double-precision configuration because the Cortex-R52 can only be configured as such. Reference: https://developer.arm.com/Processors/Cortex-R52 Instruction set: Arm and Thumb-2. Supports DSP instructions and a configurable Floating-Point Unit either with single-precision or double precision and Neon. Signed-off-by: chao an <anchao@lixiang.com> |
