◆ dump_insn_slim()
Emit a slim dump of X (an insn) to the file F, including any register note attached to the instruction.

Same as above, but stop at LAST or when COUNT == 0. If COUNT < 0 it will stop only at LAST or NULL rtx.

◆ dump_value_slim()
Print X, an RTL value node, to file F in slim format. Include additional information if VERBOSE is nonzero. Value nodes are constants, registers, labels, symbols and memory.

◆ print_insn()
|
extern |
This is the main function in slim rtl visualization mechanism. X is an insn, to be printed into PP. This function tries to print it properly in human-readable form, resembling assembler mnemonics (instead of the older Lisp-style form). If VERBOSE is TRUE, insns are printed with more complete (but longer) pattern names and with extra information, and prefixed with their INSN_UIDs.

◆ print_rtx_function()
Write FN to OUTFILE in a form suitable for parsing, with indentation
and comments to make the structure easy for a human to grok. Track
the basic blocks of insns in the chain, wrapping those that are within
blocks within "(block)" directives.
If COMPACT, then instructions are printed in a compact form:
- INSN_UIDs are omitted, except for jumps and CODE_LABELs,
- INSN_CODEs are omitted,
- register numbers are omitted for hard and virtual regs, and
non-virtual pseudos are offset relative to the first such reg, and
printed with a '%' sigil e.g. "%0" for (LAST_VIRTUAL_REGISTER + 1),
- insn names are prefixed with "c" (e.g. "cinsn", "cnote", etc)
Example output (with COMPACT==true):
(function "times_two"
