=head1 NAME
t/native_pbc/number.t - Native Floating-Point Numbers
=head1 SYNOPSIS
% prove t/native_pbc/number.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 on 4 different machines.
=head1 PLATFORMS
The id consists of ptrsize in byte, numvalsize in bytes and le/be for
little/big-endian.
4_8_le: i386 32 bit opcode_t, 4 byte intval, 8 byte double
(linux-gcc-i386, freebsd-gcc, cygwin, ...)
4_8_be: PPC BE 32 bit opcode_t, 4 byte intval, 8 byte double
(darwin-ppc or sparc32)
8_8_le: x86_64 64 bit opcode_t, 8 byte intval, 8 byte double
(linux-gcc-x86_64 resp. amd64, solaris-cc-64int)
8_8_be: big-endian 64 bit opcode_t, 8 byte intval, 8 byte double
(Sparc64/Solaris, MIPS irix or similar)
4_12_le: i386 32 bit opcode_t, 4 byte intval, 12 byte long double
(linux-gcc-i386 or cygwin with --floatval="long double")
8_16_le: x86_64 64 bit opcode_t, 8 byte intval, 16 byte long double
(linux-gcc-x86_64, solaris-cc-64int --floatval="long double")
8_16_be: big-endian 64 bit opcode_t, 8 byte intval, 16 byte long double
(Sparc64/Solaris --floatval="long double")
4_4_le: i386 32 bit opcode_t, 4 byte intval, 4 byte single float
(linux-gcc-i386 or cygwin with --floatval="float")
4_4_be: big-endian 32 bit opcode_t, 4 byte intval, 4 byte single float
(darwin or debian/ppc with --floatval="float")

# These are PBC files generated from F<t/native_pbc/testdata/number.pasm> with
# different architectures.
# If your wordsize/floattype/endianess is not covered here
# please add it:
$ ./parrot -o n.pbc t/native_pbc/testdata/number.pasm
$ make pbc_dump
$ ./pbc_dump -h n.pbc
$ mv n.pbc t/native_pbc/number_$(id).pbc
# then
# - increase number of tests
# - include the pbc_dump header info for reference
# - put the file into MANIFEST
# - then add the file with "git add" and commit it
# thanks -leo and reini
On test failures please add the output of
$ ./pbc_dump -h t/native_pbc/number_${id}.pbc
into your report. We need your wordsize/floattype/endianess.
