|

# Extra flags to be appended when compiling C files (but not C++ files).
|
|
# - extra_cppflags
|
|
# Extra flags to be appended when compiling both C and C++ files. "CPP"
|
|
# stands for "C PreProcessor" in this context, although it can be
|
|
# used for non-preprocessor flags as well. Not to be confused with
|
|
# "CXX" (which follows).
|
|
# - extra_cxxflags
|

# Extra flags to be appended when compiling C++ files (but not C files).
|
|
# - extra_asmflags
|
|
# Extra flags to be appended when compiling assembly.
|

# - extra_ldflags
|

# Extra flags to be appended when linking
|

#
|
|
# - libs_section_prefix
|

# - libs_section_postfix
|

# the libs section of the linker line. It allows one to inject libraries
|
|
# at the beginning and end for all targets in a toolchain.
|
|
# - solink_libs_section_prefix
|
|
# - solink_libs_section_postfix
|
|
# Same as libs_section_{pre,post}fix except used for solink instead of link.
|
|
# - link_outputs
|
|
# The content of this array, if specified, will be added to the list of
|
|
# outputs from the link command. This can be useful in conjunction with
|
|
# the post_link parameter.
|
|
# - use_unstripped_as_runtime_outputs
|
|
# When |strip| is set, mark unstripped executables as runtime deps rather
|
|
# than stripped ones.
|
|
# - post_link
|
|
# The content of this string, if specified, will be run as a separate
|
|
# command following the the link command.
|
|
# - deps
|
|
# Just forwarded to the toolchain definition.
|
|
# - executable_extension
|
|
# If this string is specified it will be used for the file extension
|
|
# for an executable, rather than using no extension; targets will
|
|
# still be able to override the extension using the output_extension
|
|
# variable.
|
|
# - rebuild_define
|
|
# The contents of this string, if specified, will be passed as a #define
|
|
# to the toolchain. It can be used to force recompiles whenever a
|
|
# toolchain is updated.
|
|
# - shlib_extension
|
|
# If this string is specified it will be used for the file extension
|
|
# for a shared library, rather than default value specified in
|
|
# toolchain.gni
|
|
# - strip
|
|
# Location of the strip executable. When specified, strip will be run on
|
|
# all shared libraries and executables as they are built. The pre-stripped
|
|
# artifacts will be put in lib.unstripped/ and exe.unstripped/.
