4c3296960d Remove the dual-callback scheme for numeric and pointer thread IDs, 
deprecate the original (numeric-only) scheme, and replace with the
CRYPTO_THREADID object. This hides the platform-specifics and should reduce
the possibility for programming errors (where failing to explicitly check
both thread ID forms could create subtle, platform-specific bugs).

Thanks to Bodo, for invaluable review and feedback.

830b8877ba Takanori Yanagisawa has shown how to correctly use pre-computed values.

BN_nist_mod_224 yet].

f7ccba3edf There was a need to support thread ID types that couldn't be reliably cast 
to 'unsigned long' (ie. odd platforms/compilers), so a pointer-typed
version was added but it required portable code to check *both* modes to
determine equality. This commit maintains the availability of both thread
ID types, but deprecates the type-specific accessor APIs that invoke the
callbacks - instead a single type-independent API is used.  This simplifies
software that calls into this interface, and should also make it less
error-prone - as forgetting to call and compare *both* thread ID accessors
could have led to hard-to-debug/infrequent bugs (that might only affect
certain platforms or thread implementations). As the CHANGES note says,
there were corresponding deprecations and replacements in the
thread-related functions for BN_BLINDING and ERR too.

7a5dbeb782 Minor sparcv9 clean-ups. 2005-12-27 21:27:39 +00:00
Andy Polyakov
3b4a0225e2 As SPARCV9 CPU flavor is [expected to be] detected at run-time, we can 
afford to relax SPARCV9/8+ compiler command line and produce "unversal"
binaries as we used to.

a00e414faf Unify sparcv9 assembler naming and build rules among 32- and 64-bit builds. 
Engage run-time switch between bn_mul_mont_fpu and bn_mul_mont_int.

68ea60683a Add IALU-only bn_mul_mont for SPARCv9. See commentary section for details. 2005-12-15 22:43:33 +00:00

6df8c74d5b Switch 64-bit sparcv9 platforms from bn(64,64) to bn(64,32). This doesn't 
have impact on performance, because amount of multiplications does not
increase with this switch, not on sparcv9 that is. On the contrary, it
actually improves performance, because it spares a load of instructions
used to chase carries. Not to mention that BN assembler modules can be
shared more freely between 32- and 64-bit builts.
