=head1 NAME
t/native_pbc/integer.t - Integers
=head1 SYNOPSIS
% prove t/native_pbc/integer.t
=head1 DESCRIPTION
Tests word-size/float-type/endian-ness for different architectures.
These tests usually only work on updated native pbc test files.
See F<tools/dev/mk_native_pbc> to create the platform-specific
native pbcs.
=head1 PLATFORMS
_1 (4_le) i386 32 bit opcode_t, 4 byte intval, 8 byte double
(linux-gcc-i386, freebsd-gcc, cygwin, ...)
_2 (4_le) i386 32 bit opcode_t, 4 byte intval, 12 byte long double
(linux-gcc-i386 or cygwin with --floatval="long double")
_3 (4_be) PPC BE 32 bit opcode_t, 4 byte intval, 8 byte double
(darwin-ppc or sparc32)
_4 (8_le) x86_64 64 bit opcode_t, 8 byte intval, 8 byte double

(Sparc64/Solaris --floatval="long double")
_8 (4_le) i386 32 bit opcode_t, 4 byte intval, 4 byte single float
(linux-gcc-i386 or cygwin with --floatval="float")

=begin comment
See t/native_pbc/number.t for additional comments.
See tools/dev/mk_native_pbc to create the platform-specific native pbcs.
Test files on different architectures are generated by:
$ parrot -o i.pbc -a - <<EOF
print 0x10203040
end
EOF
$ mv i.pbc t/native_pbc/integer_${N}.pbc
The output of
$ pbc_dump -h i.pbc
should be included for reference.
On test failures please add the output of
$ ./pbc_dump -h t/native_pbc/number_${N}.pbc
into your report. We need your wordsize/floattype/endianess.
