# Makefile for PIC32 native library for Rust runtime

# A 'normal' GCC toolchain can be used as well for processing the assembly files
# rather than the ChipKit or XC32 toolchain. When using a 'normal' GCC toolchain,
# the object file patching with bbe is not needed.
# The "Quoted section flags are deprecated" warning from pic32-gcc can be
# ignored.
