# ccswitch.strs: project-agnostic list of compiler switches, # for which support is tested by default. # when -foo is supported by the host or native compiler, add # ``CFLAGS_foo = -foo'' to the respective ccenv variable file # (that is, ccenv/host.mk or ccenv/native.mk). # the make variable prefix is _CFLAGS_ or _NATIVE_CFLAGS_ # (_LDFLAGS_ or _NATIVE_LDFLAGS for -Wl, linker options), # to which the compiler-switch, minus leading dashes and # trailing equal-sign or comma, is appended; non-leading # dashes and non-trailing equal-signs and commas are then # substituted with underscores. # the project-agnostic list below can be supplemented by a # project-specific one, named project/config/ccswitch.strs. # toolchain switches -dumpmachine -print-file-name= # flavors and variants -std=c89 -std=c99 -std=c11 # linker switches -Wl,--print-map -Wl,--no-undefined -Wl,--verbose # errors and warnings -Wall -Werror -Wextra -Wundef -Wpedantic # debugging -g -g0 -g1 -g2 -g3 # optimization -O0 -O1 -O2 -O3 -Os
