Apparently the AIX and Darwin JIT fixes have broken the Linux PPC build,
which
doesn't pick up the appropriate hints file. I tried a couple of ways to
force
it to do so to no avail. Someone who knows what he's doing will have to
do it.

The selection of the missing helper file should be done by "jitcpuarch"
and not by IIRC platform. As it's a JIT only thingy, the proper place to
include that file is in jit.pl.

Alright, poking around blindly for an hour, I made the changes in the
attached patch (not for applying) and came up with a different breakage:
as -o src/platform_asm.o src/platform_asm.s
src/platform_asm.s: Assembler messages:
src/platform_asm.s:3: Error: Unrecognized opcode: `this'
src/platform_asm.s:4: Error: Unrecognized opcode: `rather'
src/platform_asm.s:5: Error: syntax error; found `i' but expected `,'
src/platform_asm.s:5: Error: junk at end of line: `is not
currently configurable in the Parrot makefiles'
src/platform_asm.s:7: Error: unexpected end of file in macro
definition
make: *** [src/platform_asm.o] Error 1
Running 'gcc' or 'cc' on the file produces the same error, as you'd
expect.

the expected t/library/streams.t failure present with make test too).
The attached file works as the eventual src/platform_asm.s file, at
least on my architecture. I'm not sure how to plug it in to the
generated fileset cleanly, but that's a lot easier than trying to debug
assembly code on a platform you don't have.
Leo, what do you suggest to connect the dots here?

He he, great.

Well, we need a more generic way to include such files.
* platform_asm.s is just one file and depends on $platform.
But we have as $jitarchname:
ppc-darwin
ppc-aix
ppc-linux # AFAIK
This file is common for all PPC JIT architectures.
OTOH there is a config dispatch on $cpu in config/gen/cpu, but that is
for C files.
But as this "asm.s" is JIT-specific and needed for PPC it should be
included by jit.pl.
Where are the config hackers ;)

Here's a patch that's only a little bit ugly but makes things work
automatically for me again.
