const var_decl_sptr find_data_member ( const string & name ) const

Find a data member of a given name in the current class_or_union.

name	the name of the data member to find in the current class_or_union.

Returns: a pointer to the var_decl that represents the data member to find inside the current class_or_union.

Definition at line 23750 of file abg-ir.cc.

◆ find_data_member() [2/2]

const var_decl_sptr find_data_member ( const var_decl_sptr & v ) const

Find a given data member.

This function takes a var_decl as an argument. If it has a non-empty name, then it tries to find a data member which has the same name as the argument.

If it has an empty name, then the var_decl is considered as an anonymous data member. In that case, this function tries to find an anonymous data member which type equals that of the var_decl argument.

Parameters

v	this carries either the name of the data member we need to look for, or the type of the anonymous data member we are looking for.

◆ equals [1/2]

bool equals	(	const class_decl &	l,
		const class_decl &	r,
		change_kind *	k )

friend

Compares two instances of class_decl.

If the two intances are different, set a bitfield to give some insight about the kind of differences there are.

Parameters

l	the first artifact of the comparison.
r	the second artifact of the comparison.
k	a pointer to a bitfield that gives information about the kind of changes there are between `l` and `r`. This one is set iff `k` is non-null and the function returns false.

Please note that setting k to a non-null value does have a negative performance impact because even if l and r are not equal, the function keeps up the comparison in order to determine the different kinds of ways in which they are different.

Returns: true if l equals r, false otherwise.
