Detailed Description

A stack of sets of classifications: each entry in the stack is
a mapping from option index to diagnostic severity that can be changed
via pragmas.  The stack can be pushed and popped.   

Member Function Documentation

classify_diagnostic()

diagnostic_t diagnostic_option_classifier::classify_diagnostic	(	const diagnostic_context *	context,
		int	option_index,
		diagnostic_t	new_kind,
		location_t	where )

Interface to specify diagnostic kind overrides.  Returns the
previous setting, or DK_UNSPECIFIED if the parameters are out of
range.  If OPTION_INDEX is zero, the new setting is for all the
diagnostics.

Restore the topmost classification set off the stack.  If the stack
is empty, revert to the state based on command line parameters.

(

Save all diagnostic classifications in a stack.

update_effective_level_from_pragmas()

diagnostic_t diagnostic_option_classifier::update_effective_level_from_pragmas

(

diagnostic_info *

diagnostic

)

const

Update the kind of DIAGNOSTIC based on its location(s), including
any of those in its inlining stack, relative to any
  #pragma GCC diagnostic
directives recorded within this object.

Return the new kind of DIAGNOSTIC if it was updated, or DK_UNSPECIFIED
otherwise.
