Detailed Description

Congruence class encompasses a collection of either functions or
read-only variables. These items are considered to be equivalent
if not proved the opposite.

Member Function Documentation

◆ dump()

void ipa_icf::congruence_class::dump	(	FILE *	file,
		unsigned int	indent = 0 ) const

Dump function prints all class members to a FILE with an INDENT.
