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,
		diagnostic_option_id	option_id,
		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_ID is zero, the new setting is for all the
diagnostics.

◆ pch_restore()

int diagnostic_option_classifier::pch_restore ( FILE * f )

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

◆ pch_save()

int diagnostic_option_classifier::pch_save ( FILE * f )

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

◆ pop()

void diagnostic_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.

◆ push()

void diagnostic_option_classifier::push ( )

Save all diagnostic classifications in a stack.

Referenced by diagnostic_context::push_diagnostics().

◆ 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.
