# AVR compile patterns
# --------------------

## Compile c files
recipe.c.o.pattern={compiler.path}{compiler.c.cmd} {compiler.c.flags} -mmcu={build.mcu} -DF_CPU={build.f_cpu} -D{software}={runtime.ide.version} {build.extra_flags} {includes} {source_file} -o {object_file}

## Compile c++ files
recipe.cpp.o.pattern={compiler.path}{compiler.cpp.cmd} {compiler.cpp.flags} -mmcu={build.mcu} -DF_CPU={build.f_cpu} -D{software}={runtime.ide.version} {build.extra_flags} {includes} {source_file} -o {object_file}

## Create archives
recipe.ar.pattern={compiler.path}{compiler.ar.cmd} {compiler.ar.flags} {build.path}/{archive_file} {object_file}

## Combine gc-sections, archives, and objects
recipe.c.combine.pattern={compiler.path}{compiler.c.elf.cmd} {compiler.c.elf.flags} -mmcu={build.mcu} -o {build.path}/{build.project_name}.elf {object_files} {build.path}/{archive_file} -L{build.path} -lm

## Create eeprom
recipe.objcopy.eep.pattern={compiler.path}{compiler.objcopy.cmd} {compiler.objcopy.eep.flags} {build.path}/{build.project_name}.elf {build.path}/{build.project_name}.eep

## Create hex
recipe.objcopy.hex.pattern={compiler.path}{compiler.elf2hex.cmd} {compiler.elf2hex.flags} {build.path}/{build.project_name}.elf {build.path}/{build.project_name}.hex

## Compute size
recipe.size.pattern={compiler.path}{compiler.size.cmd} -A {build.path}/{build.project_name}.hex
recipe.size.regex=Total\s+([0-9]+).*
