# Update a local CVS tree from the GCC repository, with an emphasis
|
|
# on treating generated files correctly, so that autoconf, gperf et
|
|
# al are not required for the ``end'' user.
|
|
#
|
|
# By default all command-line options are passed to `cvs update` 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 cvs 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# only generated files that appear to be out of date in the local tree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.
|
|
#
|
|
# Examples:
|
|
#
|
|
# contrib/gcc_update -r gcc_latest_snapshot
|
|
# contrib/gcc_update -A
|
|
# contrib/gcc_update --nostdflags -P -r gcc-2_95-branch gcc/testsuite
|
|
# contrib/gcc_update --patch some-patch
