=head1 NAME
examples/benchmarks/boolean.pir: Manipulate the Boolean PMC
=head1 SYNOPSIS
parrot examples/benchmarks/boolean.pir
=head1 DESCRIPTION
This benchmark operates on the Boolean PMC, allocating new ones, setting them,
and performing logical operations on them.
=cut
.const num iterations = 10e6 # Number of iterations.
.sub main :main
.local num start_time, end_time
.local int counter
.local pmc a, b, c, result
print "Perform "
print iterations
say " iterations of various Boolean operations"
a = new 'Boolean', 1
start_time = time
counter = iterations
LOOP:
b = new 'Boolean'
b = 1
c = new 'Boolean', b
result = not a
result = and result, b
result = or result, c
not result
if result goto TRUE
a = 0
goto NEXT
TRUE:
a = 1
NEXT:
dec counter
if counter > 0 goto LOOP
end_time = time
end_time = end_time - start_time
end_time = end_time / iterations
print "Elapsed time per iteration: "
say end_time
