; This file is processed by the script opts.sh. It is a database of
; command line options, with each record separated by a blank line,
; and each field appearing on its own line. The first field is the
; command-line switch with the leading "-" removed. All options
; beginning with "f" or "W" are implicitly assumed to take a "no-"
; form; this form should not be listed. If you do not want this
; negative form and you want it to be automatically rejected, add
; RejectNegative to the second field.
; The second field is a space-separated list of which parts of the
; compiler recognize the switch, as declared by "Language" entries.
; If the switch takes an argument, then you should also specify
; "Joined" and/or "Separate" to indicate where the argument can
; appear. If a Joined argument can legitimately be omitted, specify
; "JoinedOrMissing" instead of "Joined". If the argument to a switch
; is a non-negative integer, you can specify "UInteger" and the switch
; decoder will convert the argument for you, or complain to the user
; if the argument is invalid.
; The third field is the help text to output with --help. This is
; automatically line-wrapped on output. Normally the switch is output
; automatically, with the help text on the right hand side of the
; output. However, if the help text contains a tab character, the
; text to the left of the tab is output instead of the switch, and the
; text to its right forms the help. This is useful for elaborating on
; what type of argument a switch takes, for example. If the second
; field contains "Undocumented" then nothing is output with --help.
; Only do this with good reason like the switch being internal between
; the driver and the front end - it is not an excuse to leave a switch
; undocumented.
; Comments can appear on their own line anwhere in the file, preceded
; by a semicolon. Whitespace is permitted before the semicolon.
; For each switch XXX below, an enumeration constant is created by the

The case where EXP the initializer is a call to a constructor or a

standard; it's unclear whether or not it should be allowed to
throw. We used to say no, as that allowed us to optimize this
case without worrying about deallocating the exception object if
it does. But that conflicted with expectations (PR 13944) and the
EDG compiler; now we wrap the initialization in a TRY_CATCH_EXPR
to call do_free_exception rather than in a MUST_NOT_THROW_EXPR,
