substring locations and # line directives (PR preprocessor/78569)
The ICE in PR preprocessor/78569 appears to be due to an attempt to
generate substring locations in a .i file where the underlying .c file
has changed since the .i file was generated.
This can't work, so it seems safest for the on-demand substring
locations to be unavailable for such files, falling back to
"whole string" locations for such cases.
gcc/ChangeLog:
PR preprocessor/78569
* input.c (get_substring_ranges_for_loc): Fail gracefully if
line directives were present.
gcc/testsuite/ChangeLog:
PR preprocessor/78569
* gcc.dg/format/pr78569.c: New test case.
