Hi,
I decided to look at how difficult it would be to get the
recently released parrot 1.0.0 going on NetBSD/macppc 4.0.
The answer turned out to be "not very". :) Cheers for good
portability! (But there's another bug report on the way
about a non-portable use of the == operator to the "test"
program...)
I had to make a few minor adjustments to the code, due to the
following differences between the Linux/ppc and NetBSD/macppc
(or generally NetBSD/powerpc) targets:
1) The assembler on NetBSD/macppc insists that powerpc registers
must be named with a % prefix. I have verified that Linux/ppc
accepts that syntax as well.
2) There is some strange difference going on with respect to
whether externally visible symbols in assembly should have
a leading underscore or not, apparently. This affects the
minimal assembly fragment for saving the non-volatile
registers. Since the assembly code is apparently passed
through the preprocessor, a simple #ifdef cured this problem.
3) A couple of ELF-related PPC preprocessor symbols are named
differently in NetBSD. I'm not entirely sure where the
correct place is for that workaround -- feel free to relocate
to a more appropriate spot.
I've attached my local changes to deal with these three issues.
With these in place, my build completed, and a "make test"
succeeded with
All tests successful, 17 tests and 580 subtests skipped.
Files=398, Tests=11569, 584 wallclock secs (429.43 cusr + 106.05 csys =
535.48 CPU)
Your already tracked issue for OpenBSD at
http://rt.perl.org/rt3//Public/Bug/Display.html?id=40959
should also be fixed by this particular bugfix.
I'll also note that during the build a number of warnings are
emitted, similar to this:
src/ops/core_ops_switch.c
src/ops/core.ops: In function 'switch_core':
src/ops/core.ops:165: warning: cast increases required alignment of target
type
src/ops/core.ops:191: warning: cast increases required alignment of target
type
src/ops/core.ops:204: warning: cast increases required alignment of target
type
src/ops/core.ops:212: warning: cast increases required alignment of target
type
src/ops/core.ops:236: warning: cast increases required alignment of target
type
(the list goes on, also for several other files...) The first
one of these appears to be (from src/ops/core_ops_switch.c:
case 8: /* load_bytecode_s */ {
#line 165 "src/ops/core.ops"
Parrot_load_bytecode(interp, (*(STRING **)OP_AS_OFFS(1)));
