Subject: [PATCH] [Driver] Move CommonArgs to a location visible by the
Frontend Drivers
This patch moves the CommonArgs utilities into a location visible by the
Frontend Drivers, so that the Frontend Drivers may share option parsing code
with the Compiler Driver. This is useful when the Frontend Drivers would like
to verify that their incoming options are well-formed and also not reinvent the
option parsing wheel.
We already see code in the Clang/Flang Drivers that is parsing and verifying its
incoming options. E.g. OPT_ffp_contract. This option is parsed in the Compiler
Driver, Clang Driver, and Flang Driver, all with slightly different parsing
code. It would be nice if the Frontend Drivers were not required to duplicate
this Compiler Driver code. That way there is no maintenace burden on keeping all
these parsing functions in sync.
Along those lines, the Frontend Drivers will now have a useful mechanism to
verify their incoming options are well-formed. Currently, the Frontend Drivers
trust that the Compiler Driver is not passing back junk. In some cases, the
Language Drivers will accept junk with no error at all. E.g.:
`clang -cc1 -mprefer-vector-width=junk test.c'
With this patch, we'll now be able to tighten up incomming options to the
Frontend drivers in a lightweight way.
