The following testcase fails to assemble, as CONST_STRING in the DEBUG_INSNs
is printed as is, so if it contains \n and/or \r, we are in trouble:
.loc 1 14 3
# DEBUG haystack => [si]
# DEBUG needle => "
"
In the gimple dumps we print those (STRING_CSTs) as
# DEBUG haystack => D#1
# DEBUG needle => "\n"
so this patch uses what we use in tree printing for the CONST_STRINGs too.

PR middle-end/93399
* tree-pretty-print.h (pretty_print_string): Declare.
* tree-pretty-print.c (pretty_print_string): Remove forward
declaration, no longer static. Change nbytes parameter type
from unsigned to size_t.
* print-rtl.c (print_value) <case CONST_STRING>: Use
pretty_print_string and for shrink way too long strings.
* gcc.dg/pr93399.c: New test.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
