You mentioned Montgomery BN.
Here are how the instructions work.
The basic model is that there is a range of sizes supported by the
instruction, and all of the data is loaded into a combination of
the floating point registers and all of the register windows of
the cpu.
Ouch!
...
Provide these so that the assembler users can be oblivious about
whether this is PIC or non-PIC, 64-bit or 32-bit, etc.
It is important to use a real call and return to implement the
obtaining of the %pc as part of the PIC sequence. Sequences
such as:
call. + 8
mov
Attached are patches for 1.0.0 and 0.9.8.

Attached are patches for 1.0.0 and 0.9.8.
Note, I updated the original change to retain compatibility with
existing behaviour as far as possible. See:

Hi Steve.
I saw your update (to 1.0.2 and HEAD), and I did start looking at
backporting it into my 1.0.1/1.0.0/0.9.8 patches.
ssl_get_server_send_pkey() is not available in 1.0.1 and earlier, so the
t1_lib.c patch would have to be something like...
+ X509 *x;
+ x =

Easiest solution is to also backport ssl_get_server_send_pkey see:
http://cvs.openssl.org/chngview?cn=22840
I didn't think of that. Thanks!
I'll prepare patches to backport 22840 to 1.0.0

No, before thinking about 32-bit mode, I quickly ask what's with save-s
without arguments?
Sorry, I just wrote that code as pseudo-code off the top of my
head without attending to all of the necessary details.

I'll handle this, but differently. Specifically I won't go through GOT,
but directly to variable, something like this:
I would like to politely request that you don't go down this road.

Here is a more detailed reply specifically about generating
correct and optimal Sparc PIC sequences.
Let's get the non-PIC static case out of the way, we should
always use:
set symbol, %reg! 32-bit
setxsymbol, %tmp_reg, %reg ! 64-bit
Using calls to PIC
This builds on top of the 7 patch series I sent the other day which
laid the foundation for sparc crypto opcode support.
The first patch plugs in optimized versions of key expansion and
AES_{decrypt,encrypt}()
The second patch is modelled on the AESNI support and explicitly
optimizes ECB, CBC,
Currently AES_encrypt, AES_decrypt, and the key expansion are
optimized. Direct support for CBC, ECB, CTR, etc. will come
in subsequent changes.
The following measurements were taken on a SPARC-T4.
