Bug ID: 80058 Summary: fix double spaces is string literals everywhere Product: gcc Version: 7.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: other Assignee: unassigned at gcc dot gnu.org Reporter: roland.illig at gmx dot de Target Milestone: --- Searching the whole GCC source code for the following regular expression finds a few places in the code: [ ]"\n[ \t]+"[ ] This expression finds concatenated string literals where the first ends with a space and the second starts with a space, like these: gfc_warning_now (w, "Change of value in conversion from " " %qs to %qs at %L", gfc_typename (&src->ts), gfc_typename (&result->ts), &src->where); The above code and all similar places should be fixed so that they only have a single space character.
