## Summary Update the Green Hills (GHS) toolchain FPU flags for Cortex-M4 and Cortex-M7 targets to use the recommended VFP versions per Armv7-M architecture documentation: 1. Cortex-M4: change vfpv3/vfpv3_d16 → vfpv4/vfpv4_d16 2. Cortex-M7: change vfpv3/vfpv3_d16 → vfpv5/vfpv5_d16 ## Impact 1. Aligns FPU configuration with the actual hardware capabilities of Cortex-M4 (VFPv4) and Cortex-M7 (VFPv5) processors 2. Ensures correct FPU instruction generation and potential performance improvements by using the appropriate VFP version ## Testing Verified compilation for Cortex-M4 and Cortex-M7 targets using Green Hills toolchain with FPU enabled (both single and double precision) -- This is an automated message from the Apache Git Service.
