=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 DOD 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:
SArray: Entry not an integer!
=cut
# How can I get to the command line args?
#set I10, P5
#lt I10, 2, noarg
#set I11, P5[1]
set I11, 0
noarg:
set I0, 100
new P0, 'ResizablePMCArray'
ol: bsr 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'
l2:
new P1, 'Integer'
set P3[0], P1
dec I0
if I0, l2
interpinfo I1, 2
print "A total of "
print I1
print " DOD runs were made\n"
interpinfo I1, 4
print I1
print " active PMCs\n"
interpinfo I1, 6
print I1
print " total PMCs\n"
end
# Our inner loop, 10000 times
buildarray:
set I1, 10000
new P1, 'ResizablePMCArray'
loop1: new P9, 'Integer'
set P9, I1
set P1[I1], P9
dec I1
if I1, loop1
