Roland McGrath 81043d1ad8 2003-01-16 Roland McGrath <roland@redhat.com>
Tweak merged .abilist file format to merge duplicate symbols in
	different sets into multi-version stanzas with new "| SET regexp..."
	header continuation lines.
	* scripts/merge-abilist.awk: Rewritten for new format.
	* scripts/extract-abilist.awk: Likewise.

Awk

# awk script to extract a config-specific .symlist file from a merged file.
# This must be passed run with awk -v config=TUPLE to specify the configuration
# tuple we will match. The merged file contains stanzas in the form:
# GLIBC_x.y regexp...
# | GLIBC_x.y.z regexp...
# | GLIBC_m.n regexp...
# function F
# variable D 0x4
# Each regexp is matched against TUPLE, and only matching stanzas go
# into the output, with the regexp list removed. Multiple version lines
# can match with the same regexp, meaning the stanza is duplicated in
# multiple version sets. The result matches the original .symlist file
# from abilist.awk that was fed into merge-abilist.awk.
