/* The functions in this file try to print RTL in a form resembling assembler

mnemonics. Because this form is more concise than the "traditional" form

of RTL printing in Lisp-style, the form printed by this file is called
|

"slim". RTL dumps in slim format can be obtained by appending the "-slim"
|

option to -fdump-rtl-<pass>. Control flow graph output as a DOT file is
|

always printed in slim form.
|

|
||
The normal interface to the functionality provided in this pretty-printer
|
||
is through the dump_*_slim functions to print to a stream, or via the
|
||
print_*_slim functions to print into a user's pretty-printer.
|

|

It is also possible to obtain a string for a single pattern as a string
|

pointer, via str_pattern_slim, but this usage is discouraged. */
