value_data_entry Struct Reference

Collaboration diagram for value_data_entry:

Data Fields
enum machine_mode	mode
unsigned int	oldest_regno
unsigned int	next_regno
struct queued_debug_insn_change *	debug_insn_changes

---

Detailed Description

For each register, we have a list of registers that contain the same
   value.  The OLDEST_REGNO field points to the head of the list, and
   the NEXT_REGNO field runs through the list.  The MODE field indicates
   what mode the data is known to be in; this field is VOIDmode when the
   register is not known to contain valid data.
