[cirras]

Prerequisites

• This improvement has not already been suggested.
• This improvement would be generally useful, not specific to my code or setup.

Engine area

Delphi language support

Improvement description

Delphi 13 has introduced new compiler directives {$PUSHOPT} and {$POPOPT}.

These new Delphi compiler directives save and restore the current set of options and warning configurations.

We'll need to:

• parse the new directives
• add support to the CompilerSwitchRegistry
• API: extend the ParameterDirective.ParameterKind enum

See

• Option OPT (Delphi)

Rationale

Delphi 13 support.
