Hi David, Hi Martin, OK, take 3 of the patch is attached. In this version:
* The escaping is handled by a new class. * Self-tests have been added (and they helped find a bug - yay!) * The documentation has been extended to mention -fmessage-length's effect on the #-directives, and to add documentation for #pragma GCC error and #pragma GCC warning. (Which appeared to be missing). I did try to add backslash characters to the regexp in the new testcase but I just could not find a way to persuade dejagnu to accept them. OK to apply ? (Apologies for the poor C++ coding - it is not my strong point. I am an assembler level programmer at heart). Cheers Nick gcc/ChangeLog 2018-02-09 Nick Clifton <ni...@redhat.com> PR 84195 * tree.c (escaped_string): New class. Converts an unescaped string into its escaped equivalent. (warn_deprecated_use): Use the new class to convert the deprecation message, if present. (test_escaped_strings): New self test. (test_c_tests): Add test_escaped_strings. gcc/testsuite/ChangeLog 2018-02-07 Nick Clifton <ni...@redhat.com> * gcc.c-torture/compile/pr84195.c: New test.
