# Perftest description file for building the "gmonster2" benchmark.
# Where does the name come from?  The benchmark is derived from one of the
# monster programs at Google.
#
# Perftest descriptions are loaded thrice:
# 1) To generate the build .exp files
#    GDB_PERFTEST_MODE=gen-build-exps
#    This step allows for parallel builds of the majority of pieces of the
#    test binary and shlibs.
# 2) To compile the "pieces" of the binary and shlibs.
#    "Pieces" are the bulk of the machine-generated sources of the test.
#    This step is driven by lib/build-piece.exp.
#    GDB_PERFTEST_MODE=build-pieces
# 3) To perform the final link of the binary and shlibs.
#    GDB_PERFTEST_MODE=compile
#
# Example usage:
# bash$ make -j5 build-perf RUNTESTFLAGS="gmonster1.exp gmonster2.exp"
# bash$ make check-perf RUNTESTFLAGS="gdb.perf/gm*-*.exp GDB=/path/to/gdb"
