Bug ID: 110980
Summary: -flang-info-include-translate does not work with no
argument
Product: gcc
Version: 13.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: namniav at gmail dot com
Target Milestone: ---
Docs says that with no argument -flang-info-include-translate will note all
include translation. (Docs link:
https://gcc.gnu.org/onlinedocs/gcc/gcc-command-options/c%2B%2B-modules.html)
However, it doesn't work with no argument: there is no note for translating
#include <string> to import when using -flang-info-include-translate. It does
note when using -flang-info-include-translate=<string>.
