Bug ID: 107448
Summary: GCC no longer diagnoses missing input file with -MG
Product: gcc
Version: 12.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: boris at kolpackov dot net
Target Milestone: ---
With GCC 10 when trying to extract dependency information with -MG we get
diagnostics if the input file does not exist:
$ g++-10 -M -MG /tmp/no-such-file.cxx
g++-10: error: /tmp/no-such-file.cxx: No such file or directory
g++-10: fatal error: no input files
compilation terminated.
$ echo $?
1
In GCC 11 and 12 this diagnostics is gone:
$ g++-11 -M -MG /tmp/no-such-file.cxx
$ echo $?
1
$ g++-12 -M -MG /tmp/no-such-file.cxx
$ echo $?
1
