# 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_,
# 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.
