Subject: [Qemu-devel] [PATCH] target-ppc: add integer Altivec instructions, take 2
Date: Tue, 30 Dec 2008 19:09:42 -0800 [thread overview]
Message-ID: <1230693022-18380-1-git-send-email-froydnj@codesourcery.com> (raw)
This is a follow-on to:
http://lists.gnu.org/archive/html/qemu-devel/2008-12/msg01000.html
as Aurelien asked me to modify the notation for defining instructions in
target-ppc/translate.c. Since that change touched nearly every patch in
the series, I figured I would also take the opportunity to eliminate the
VECTOR_FOR macros that my patch used as well. I also fixed up various
TCG errors that turned up under DEBUG_TCG.
I did, however, leave the VECTOR_FOR_INORDER_I macros in place; I think
they are the clearest way to indicate that vectors are being iterated
over in target-endian order. Better than `#if defined(WORDS_BIGENDIAN)'
all over the code, IMHO.
As the message in:
http://lists.gnu.org/archive/html/qemu-devel/2008-12/msg01106.html
indicated, m{f,t}vscr seems to be broken in some way; the code looks
correct to me, but I can't seem to puzzle out what's wrong with it. All
other instructions have been tested against an Altivec hardware
implementation. Except for the VSCR issue above, the simulated
instructions perform identically to their hardware-implemented versions.
