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()

enum kind diagnostics::option_classifier::classify_diagnostic	(	const context *	dc,
		option_id	opt_id,
		enum kind	new_kind,
		location_t	where )

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

References get_current_override().

pch_restore()

int diagnostics::option_classifier::pch_restore

(

FILE *

f

)

Read the diagnostics::option_classifier state from F for PCH
read.  Returns 0 on success, -1 on error.   

References gcc_checking_assert, m_classification_history, and m_push_list.

pch_save()

int diagnostics::option_classifier::pch_save

(

FILE *

f

)

Save the diagnostics::option_classifier state to F for PCH
output.  Returns 0 on success, -1 on error.   

References m_classification_history, and m_push_list.

pop()

void diagnostics::option_classifier::pop

(

location_t

where

)

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

References m_classification_history, m_push_list, and diagnostics::pop.

push()

void diagnostics::option_classifier::push

(

)

Save all diagnostic classifications in a stack.   

References m_classification_history, and m_push_list.

update_effective_level_from_pragmas()

enum kind diagnostics::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 kind::unspecified
otherwise.
