64compat" ?
Andy,
At some point since I filed this ticket, the original ''TODO'' comment
vanished. So the original rationale for this ticket is largely gone.
Grepping the repository, the only reference to `--64compat` I could find
was in ''./docs/pdds/pdd13_bytecode.pod'' in a section on Packfiles:
{{{
So we relax pointer alignment strictness on Sparc64, but may add a
"--64compat" option to parrot in the future to produce 8-byte
aligned
data. Operations on aligned pointers are much faster than on un-
aligned pointers.
}}}
> I do see this puzzling note in auto/alignptrs.pm:
>
> # On 8-byte ptr_alignment we cannot read 4-byte pbc's. Warn the user
about it.
>
This comment has also disappeared.
So I propose we close this ticket and open a new one to discuss any
related issues.
If there is no objection, I'll do so in 2-3 days.
Thank you very much.[[BR]]
