Bug ID: 95364
Summary: [Regression] contrib/gcc_update -r 8712 no longer
works
Product: gcc
Version: 10.1.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
Assignee: unassigned at gcc dot gnu.org
Reporter: hjl.tools at gmail dot com
Target Milestone: ---
Before switching to git repo, we could use
$ contrib/gcc_update -r 8712
to switch to revision 8712. After switching to git, it is no longer possible
to update to a specific commit with contrib/gcc_update:
$ ./contrib/gcc_update --help
...
By default all command-line options are passed to `svn update` or `hg/git
pull` in addition to $UPDATE_OPTIONS (defined below). If the first parameter
reads --nostdflags, $UPDATE_OPTIONS as well as this parameter itself
are omitted.
If the first parameter reads --patch, the second parameter is considered
a patch file.
If the first parameter is --touch, no svn operation will be performed,
only generated files that appear to be out of date in the local tree
will be touched.
If the first parameter is --list, a list of the generated files and
their dependencies will be printed; --help prints this message.
If the first parameter is --silent, this script prints nothing other
than error messages; the second parameter is then interpreted as above.
Examples:
contrib/gcc_update -r 8712
contrib/gcc_update --patch some-patch
contrib/gcc_update --touch
contrib/gcc_update --list
UPDATE_OPTIONS=""
[hjl@gnu-cfl-2 gcc]$
The help message also mentions "svn update".
