After much struggling with macos (BSD) sed and even getting everything
work in crosstool-ng itself, I had to abandon that because some
components rely on GNU syntax. Specifically, GNU libc uses '/.../{H;g}'
(note absense of the separator after 'g').
So, revert the -r/-E detection and check for sed's being of GNU origin.
MacOS people, sorry, but you'd have to install GNU sed.

Usage: ${myname} <src_dir> <dst_dir> <base> <inc> [sed_re]
|
|
Renumbers all patches found in 'src_dir', starting at 'base', with an
|
|
increment of 'inc', and puts the renumbered patches in 'dst_dir'.
|
|
Leading digits are replaced with the new indexes, and a subsequent '_'
|
|
is replaced with a '-'.
|
|
If 'sed_re' is given, it is interpreted as a valid sed expression, and
|
|
is be applied to the patch name.
|
|
If the environment variable FAKE is set to 'y', then nothing gets done,
|
|
the command to run is only be printed, and not executed (so you can
|
|
check beforehand).
|
|
'dst_dir' must not yet exist.
|
|
Eg.:
|
|
patch-renumber.sh patches/gcc/4.2.3 patches/gcc/4.2.4 100 10
|
|
patch-renumber.sh /some/dir/my-patches patches/gcc/4.3.1 100 10 's/(all[_-])*(gcc[-_])*//;'
