# stackcollapse-ljp.awk collapse lightweight java profile reports
# into single lines stacks.
#
# Parses a list of multiline stacks generated by:
#
# https://code.google.com/p/lightweight-java-profiler
#
# and outputs a semicolon separated stack followed by a space and a count.
#
# USAGE: ./stackcollapse-ljp.pl infile > outfile
#
# Example input:
#
# 42 3 my_func_b(prog.java:455)
# my_func_a(prog.java:123)
# java.lang.Thread.run(Thread.java:744)
# [...]
#
# Example output:
#
# java.lang.Thread.run;my_func_a;my_func_b 42
#
# The unused number is the number of frames in each stack.
