=head1 NAME
examples/benchmarks/stress3.pasm - GC stress-testing
=head1 SYNOPSIS
% time ./parrot examples/benchmarks/stress3.pasm
=head1 DESCRIPTION
Creates a lot of PMCs, and then prints out some statistics indicating:
=over 4
=item * the total number of GC runs made
=item * the number of active PMCs
=item * the total number of PMC created
=back
Note that a command-line argument of 1 is supposed to cause the PMCs to
be destroyed before a 2nd loop is run. However, this seems to be broken
at the moment:
FixedPMCArray: Entry not an integer!
=cut
.pcc_sub :main main:
# How can I get to the command line args?
#set I10, P5
#lt I10, 2, noarg
#set I11, P5[1]
set I11, 0
new P10, 'ResizableIntegerArray'
noarg:
set I0, 100
new P0, 'ResizablePMCArray'
ol: local_branch P10, buildarray
set P0[I0], P1
dec I0
if I0, ol
# now check reusage, destroy them depending on I11
unless I11, no_dest
new P0, 'Undef'
no_dest:
set I0, 5000000
new P3, 'ResizablePMCArray'
