Bug ID: 64334
Summary: Common .opt handling: Support flags which take a list
of values (-fopt=a,b,c ...)
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Keywords: diagnostic
Severity: normal
Priority: P3
Component: middle-end

Split off from PR54687.
There are some options which take a list of values – and applies bitwise OR to
the choice.
Example:
fsanitize=
which takes "address" (SANITIZE_ADDRESS | SANITIZE_USER_ADDRESS),
"kernel-address" (SANITIZE_ADDRESS | SANITIZE_KERNEL_ADDRESS), "thread"
(SANITIZE_THREAD) etc. as argument.
Similarly, in Fortran: -ffpe-trap and -ffpe-summary which take "invalid",
"denormal" etc. or -fcheck= with "all", "bounds", ...
It would be useful it one could extend the current Enum scheme to support this.
