4 # Adds a new version to one of the toolchain component
7 # Parse the tools' paths configuration
8 # It is expected that this script is only to be run from the
9 # source directory of crosstool-NG, so it is trivial to find
10 # paths.mk (we can't use ". paths.mk", as POSIX states that
11 # $PATH should be searched for, and $PATH most probably doe
12 # not include "."), hence the "./".
17 Usage: ${myname} <--tool> <[options] version [...]> ...
19 gcc, binutils, glibc, eglibc, uClibc, newlib, linux, gdb, dmalloc,
20 duma, strace, ltrace, libelf, gmp, mpfr, ppl, cloog, mpc
22 Valid options for all tools:
23 --stable, -s, +x (default)
24 mark the version as being stable (as opposed to experimental, below)
26 --experimental, -x, +s
27 mark the version as being experimental (as opposed to stable, above)
29 --current, -c, +o (default)
30 mark the version as being cuurent (as opposed to obsolete, below)
33 mark the version as being obsolete (as opposed to current, above)
35 Note: setting a new tool resets to the defaults: 'stable' and 'current'.
37 'version' is a valid version for the specified tool.
40 add stable current version 2.6.19.2 to linux kernel:
41 ${myname} --linux 2.6.19.2
43 add experimental obsolete version 2.3.5 and stable current versions 2.6.1
44 and 2.6.2 to glibc, add stable obsolete version 3.3.3 to gcc:
45 ${myname} --glibc -x -o 2.3.5 -s -c 2.6.1 2.6.2 --gcc -o 3.3.3
49 # Effectively add a version to the specified tool
50 # $cat : tool category
52 # $tool_prefix : tool directory prefix
53 # $EXP : set to non empty if experimental, to empty otherwise
54 # #OBS : set to non empty if obsolete, to empty otherwise
55 # $1 : version string to add
