# This script will translate any SYMBOL_VECTOR item that has a translation
|
||
|
|
# in CXX$DEMANGLER_DB. The latter is generated by and CC/DECC command that
|
||
|
|
# uses the qualifier /REPOSITORY with the build directory as value. When
|
||
|
|
# /NAMES=SHORTENED has been used, this file will hold the translations from
|
||
|
|
# the original symbols to the shortened variants.
|
||
|
|
#
|
||
|
|
# CXX$DEMAGLER_DB. is an ISAM file, but with the magic of RMS, it can be
|
||
|
|
# read as a text file, with each record as one line.
|
||
|
|
#
|
||
|
|
# The lines will have the following syntax for any symbol found that's longer
|
||
|
|
# than 31 characters:
|
||
|
|
#
|
||
|
|
# LONG_symbol_34567890123{cksum}$LONG_symbol_34567890123_more_than_31_chars
|
||
|
|
#
|
||
|
|
# $ is present at the end of the shortened symbol name, and is preceded by a
|
||
|
|
# 7 character checksum. The $ makes it easy to separate the shortened name
|
||
|
|
# from the original one.
