/* This file defines all the codes that may appear in the
NOTE_LINE_NUMBER field of a NOTE insn for kinds of notes that are
INSN_NOTE (BLOCK_BEG)
INSN_NOTE (BLOCK_END)
-/* These mark the extremes of a loop. */
-INSN_NOTE (LOOP_BEG)
-INSN_NOTE (LOOP_END)
-
/* This note indicates the start of the real body of the function,
i.e. the point just after all of the parms have been moved into
their homes, etc. */
INSN_NOTE (FUNCTION_BEG)
-/* This kind of note is generated at the end of the function body,
- just before the return insn or return label. In an optimizing
- compilation it is deleted by the first jump optimization, after
- enabling that optimizer to determine whether control can fall
- off the end of the function body without a return statement. */
-INSN_NOTE (FUNCTION_END)
-
/* This marks the point immediately after the last prologue insn. */
INSN_NOTE (PROLOGUE_END)
INSN_NOTE (EH_REGION_BEG)
INSN_NOTE (EH_REGION_END)
-/* Generated whenever a duplicate line number note is output.
- For example, one is output after the end of an inline function,
- in order to prevent the line containing the inline call from
- being counted twice in gcov. */
-INSN_NOTE (REPEATED_LINE_NUMBER)
-
/* The location of a variable. */

-/* Record the expected value of a register at a location. Uses
