Bug ID: 91244
Summary: gcc-ar prepends --plugin option thus triggers binutils
getopt_long bug 13256
Product: gcc
Version: 9.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: driver
Assignee: unassigned at gcc dot gnu.org
Reporter: szotsaki at gmail dot com
Target Milestone: ---
"ar" seemingly doesn't accept options after a longopt (in our case "--plugin")
which makes it impossible to read instructions from command line or from a file
if "--plugin" is the first parameter. See
https://sourceware.org/bugzilla/show_bug.cgi?id=13256 for details.
Therefore I suggest appending the "--plugin" parameter to the command line
arguments.
Here is a quick patch against 9.1.0 to show what I thought of:
