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 =

Sorry, I just wrote that code as pseudo-code off the top of my
head without attending to all of the necessary details.

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 stubs
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, C
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.
Baseline (OPENSSL_sparcv9cap=0):
type 16 bytes 64 bytes256 bytes 1024 byte
On a SPARC-T4, with AES opcodes disabled (OPENSSL_sparcv9cap=0):
