--- Comment #8 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:febfe87d80c5bc8afd9038136ae7c09910a0d883 commit r10-7037-gfebfe87d80c5bc8afd9038136ae7c09910a0d883 Author: Jakub Jelinek <ja...@redhat.com> Date: Thu Mar 5 09:12:44 2020 +0100 print-rtl: Fix printing of CONST_STRING in DEBUG_INSNs [PR93399] 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. 2020-03-05 Jakub Jelinek <ja...@redhat.com> 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.
