# Compile / assemble / link flag recipe for an-mcxa174-mip-panel-demo.
#
# This is the standalone (cmake-freestanding) ACH form. The flags below
# reproduce the exact arm-none-eabi-gcc recipe captured from the reference
# MCUXpresso build:
#   - Cortex-M33, single-precision hard FPU (fpv5-sp-d16).
#   - Redlib source path (__REDLIB__ + __MCUXPRESSO) so the SDK startup runs
#     the multi-section __data_section_table copy loop that relocates
#     .SMARTDMA_CODE into SRAMX0. Link is done with newlib-nano / nosys
#     (-lm -lc -lgcc -lnosys) plus the SDK syscall/sbrk stubs.
#   - The final image is linked with the project-local Code-Red master linker
#     linker/an-mcxa174-mip-panel-demo_Debug.ld, which INCLUDEs the *_library.ld
#     and *_memory.ld sub-scripts. ld resolves INCLUDE via -L search paths, so
#     linker/ is added with -L.
