it looks like the register alligator is eating integers in this code:
.const int TESTS = 2
.sub 'main' :main
load_bytecode 'Test/More.pir'
.local pmc exp, test_ns
test_ns = get_namespace ['Test::More']
exp = new 'Exporter'
exp.'source'(test_ns)
exp.'import'('plan ok is diag isa_ok' :named('globals'))
plan(TESTS)
.local pmc attrs
attrs = new 'Hash'
.local pmc red, green, blue
attrs['name'] = 'Red'
red = new 'Role', attrs
attrs['name'] = 'Green'
green = new 'Role', attrs
attrs['name'] = 'Blue'
blue = new 'Role', attrs
green.'add_role'( blue )
.local pmc color
color = new 'Class'
$S0 = 'Red'
$I0 = color.'does'($S0)
is($I0, 0, 'does not Red')
color.'add_role'( red )
$I0 = color.'does'($S0)
is($I0, 1, 'does Red')
.end
which produces:
1..2
ok 1 - does not Red
not ok 2 - does Red
# Received: -888
# Expected: 1
either something's fishy in the PCCRETURN code, or the register
allocator. the -888 is a dead giveaway that an integer register has
been eaten. it's possible it's isolated in code called from the
'add_role' method in the Class PMC... this bug is preventing me from
testing that code.
