It seems weird to me, as a user, than the syntax to modify behavior would
not reuse the "-fsanitize" common prefix.
There is precedent in -Wl being able to forward parameters to the linker
already, so maybe a dedicated "-fsanitize-flags=address,....." could just
forward the flags (whatever they are) to ASan and let it parse them. If the
commas pose an issue, then perhaps than a "-fsanitize-address flag" would
be simpler, with the latter part (address) being taken from the list of
-------------- next part --------------
