| * Remove the 'realname' attribute on all modules and cc/cpu/os info files.lloyd2009-10-291-2/+0
| | | | | | | | | | Pretty much useless and unused, except for listing the module names in build.h and the short versions totally suffice for that.

|/ | | | | Seems binutils 2.20.51.0.2 breaks otherwise, and binutils maintainers claim it's not a bug. Meh.

* CPU-specific engines are now only loaded if something depends on them,lloyd2009-07-071-0/+1
| | | | | | | | | | | | and all CPU-specific implementations now depend on the appropriate engine module. The most common problem before with this was that the SSE2 module was built, but the sole SSE2 code (SHA-1) was not (for instance, on an i686). This would cause a compile warning about the unused request object. Preventing unused engines from being built will also (very slightly) speed up the lookup process on most system.
* Thomas Moschny passed along a request from the Fedora packagers which camelloyd2009-03-302-14/+18
| | | | | | | | | | | | | | | up during the Fedora submission review, that each source file include some text about the license. One handy Perl script later and each file now has the line Distributed under the terms of the Botan license after the copyright notices. While I was in there modifying every file anyway, I also stripped out the remainder of the block comments (lots of astericks before and after the text); this is stylistic thing I picked up when I was first learning C++ but in retrospect it is not a good style as the structure makes it harder to modify comments (with the result that comments become fewer, shorter and are less likely to be updated, which are not good things).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | to have been so! Change MDx_HashFunction::hash to a new compress_n which hashes an arbitrary number of blocks. I had a thought this might reduce a bit of loop overhead but the results were far better than I anticipated. Speedup across the board of about 2%, and very noticable (+10%) increases for MD4 and Tiger (probably b/c both of those have so few instructions in each iteration of the compression function). Before: SHA-1: amd64: 211.9 MiB/s core: 210.0 MiB/s sse2: 295.2 MiB/s MD4: 476.2 MiB/s MD5: 355.2 MiB/s SHA-256: 99.8 MiB/s SHA-512: 151.4 MiB/s RIPEMD-128: 326.9 MiB/s RIPEMD-160: 225.1 MiB/s Tiger: 214.8 MiB/s Whirlpool: 38.4 MiB/s After: SHA-1: amd64: 215.6 MiB/s core: 213.8 MiB/s sse2: 299.9 MiB/s MD4: 528.4 MiB/s MD5: 368.8 MiB/s SHA-256: 103.9 MiB/s SHA-512: 156.8 MiB/s RIPEMD-128: 334.8 MiB/s RIPEMD-160: 229.7 MiB/s Tiger: 240.7 MiB/s Whirlpool: 38.6 MiB/s
* Split asm_engine into three engines (ia32, amd64, sse2). This allowslloyd2008-11-111-0/+2

* Derive x86, x86-64, and SSE2 implementations of SHA-1 directly from SHA_160lloyd2008-09-293-35/+3

* Make asm implementations distinctly named objects, for instance MD5_IA32,lloyd2008-09-294-21/+58
| | | | | | | | | | | | | | | | | | | rather than silently replacing the C++ versions. Instead they are silently replaced (currently, at least) at the lookup level: we switch off the set of feature macros set to choose the best implementation in the current build configuration. So you can have (and benchmark) MD5 and MD5_IA32 directly against each other in the same program with no hassles, but if you ask for "MD5", you'll get maybe an MD5 or maybe MD5_IA32. Also make the canonical asm names (which aren't guarded by C++ namespaces) of the form botan_<algo>_<arch>_<func> as in botan_sha160_ia32_compress, to avoid namespace collisions. This change has another bonus that it should in many cases be possible to derive the asm specializations directly from the original implementation, saving some code (and of course logically SHA_160_IA32 is a SHA_160, just one with a faster implementation of the compression function, so this seems reasonable anyway).

* Split up asm modules into appropriate (topic-specific) modules, eglloyd2008-09-282-0/+310
hash/sha1_amd64 and cipher/serpent_ia32. Remaining code in asm/ dir is for BigInt, so rename to bigint/ in prep for all (or most) of BigInt being modularized.
