# nuttx_remove_compile_options
|
|
#
|
|
# Description:
|
|
# Customize to remove certain options
|
|
# in the default Arch ToolchainFile.
|
|
#
|
|
# For example, a customized chip board uses a customized tool chain, which has compilation configuration conflicts with default.
|
|
# You can use this macro to remove it in the global compile options.
|
|
# This function is similar to the reverse operation of `add_compile_options()`
|
|
#
|
|
# Usage:
|
|
# nuttx_remove_compile_options(ARGNS)
|
|
#
|
|
# Parameters:
|
|
# ARGNS : options regex that needs to be deleted
|
|
#
|
|
# Example:
|
|
# nuttx_remove_compile_options(-march -mabi)
|
|
#
|
|
# befor: CFLAGS = -O2 -g -march=rv32if -mabi=ilp32f -mcpu=e907fp
|
|
# after: CFLAGS = -O2 -g -mcpu=e907fp
