############## meanings of GCC options ######################################
#############################################################################
# -I dir
# Add the directory dir to the list of directories to be searched for header files.
# Directories named by -I are searched before the standard system include directories.
# If the directory dir is a standard system include directory, the option is ignored to ensure that the default search order for system directories and the special treatment of system headers are not defeated .
# If dir begins with "=", then the "=" will be replaced by the sysroot prefix; see --sysroot and -isysroot.
# -isystem dir
# Search dir for header files, after all directories specified by -I but before the standard system directories.
# Mark it as a system directory, so that it gets the same special treatment as is applied to the standard system directories.
# If dir begins with "=", then the "=" will be replaced by the sysroot prefix; see --sysroot and -isysroot.
# -include file
# Process file as if "#include "file"" appeared as the first line of the primary source file.
# However, the first directory searched for file is the preprocessor's working directory instead of the directory containing the main source file.
# If not found there, it is searched for in the remainder of the "#include "..."" search chain as normal.
# If multiple -include options are given, the files are included in the order they appear on the command line.
# -isysroot dir
# This option is like the --sysroot option, but applies only to header files (except for Darwin targets, where it applies to both header files and libraries).
# See the --sysroot option for more information
# --sysroot=dir
# Use dir as the logical root directory for headers and libraries.
# For example, if the compiler normally searches for headers in /usr/include and libraries in /usr/lib,
# it instead searches dir/usr/include and dir/usr/lib.
# If you use both this option and the -isysroot option, then the --sysroot option applies to libraries, but the -isysroot option applies to header files.
# The GNU linker (beginning with version 2.16) has the necessary support for this option.
# If your linker does not support this option, the header file aspect of --sysroot still works, but the library aspect does not.
# -mfloat-abi=name
# Specifies which floating-point ABI to use. Permissible values are: soft, softfp and hard.
# soft causes GCC to generate output containing library calls for floating-point operations.
# softfp allows the generation of code using hardware floating-point instructions, but still uses the soft-float calling conventions.
# hard allows generation of floating-point instructions and uses FPU-specific calling conventions.
#
# The default depends on the specific target configuration.
# Note that the hard-float and soft-float ABIs are not link-compatible;
# you must compile your entire program with the same ABI, and link with a compatible set of libraries.
# -msoft-float
# Use library routines for floating-point operations.
# -mhard-float
# Use hardware instructions for floating-point operations.
# -static
# On systems that support dynamic linking, this prevents linking with the shared libraries.
# On other systems, this option has no effect.
