Bug ID: 52095
Summary: Front end driver does not allow multiple dump options
Severity: release blocker
Assignee: unassignedbugs at nondot.org
Reporter: psteinfeld at nvidia.com

If I specify more than one option to the front end driver, only the last one
gets accepted. Furthermore, no error message appears saying that one of the
options was ignored.
Here's an example invocation which only dumps the symbol table:
flang-new -fc1 -fdebug-unparse -fdebug-dump-symbols hello.f90
I realize that this is a documented limitation, but I believe that we need to
be able to specify multiple dump options at the same time.
