gen_abi.sh: filter out symbols not needed for ABI gdb does not allow to print definitions of certain section names and special symbols used for dynamic loading machinery: __bss_start _edata _init _fini _end Please note the space before the pattern, it is needed to avoid hungry matches of valid symbols with these as substrings (foo_init, for example). Without this patch gdb on Fedora 18 breaks when attempting to print function and struct signature. 2012-08-23 19:45:54 +04:00			`nm "$SHAREDLIB" \| cut -d' ' -f2- \| egrep '^[BDGTRVWS]' \| grep -v @ \| egrep -v ' (__bss_start\|_edata\|_init\|_fini\|_end)' \| cut -c3- \| sort \| while read s; do`

abi: force TERM=none in abi generation on Fedora12 gdb puts out a bit of binary garbage at the front of script output when TERM=xterm, presumably trying something like a clear screen. luckily it doesn't do it for unknown terminal types Autobuild-User: Andrew Tridgell <tridge@samba.org> Autobuild-Date: Tue Jan 11 06:48:56 CET 2011 on sn-devel-104 2011-01-11 08:00:26 +03:00			`# forcing the terminal avoids a problem on Fedora12`
