This is now the case for RC5.
As a side effect, the OPTIONS in the Makefile will usually look a
little different now, but they are essentially only for information
anyway.
Idea is to provide unified "fall-down" case for all rare platforms out
there. ./config is free to enable some optimizations, such as endianness
specification, specific -mcpu flags...
apparently impossible to compose blended code with would perform
satisfactory on all x86 and x86_64 cores, an extra RC4_CHAR
code-path is introduced and P4 core is detected at run-time. This
way we keep original performance on non-P4 implementations and
turbo-charge P4 performance by factor of 2.8x (on 32-bit core).
COFF and a.out targets [similar to ELF targets]. You might notice some
rudementary support for shared mingw builds under cygwin. It works (it
produces cryptoeay32.dll and ssleay32.dll with everything exported by
name), but it's primarily for testing/debugging purposes, at least for
now...
is to have a placeholder to small routines, which can be written only
in assembler. In IA-32 case this includes processor capability
identification and access to Time-Stamp Counter. As discussed earlier
OPENSSL_ia32cap is introduced to control recently added SSE2 code
pathes (see docs/crypto/OPENSSL_ia32cap.pod). For the moment the
code is operational on ELF platforms only. I haven't checked it yet,
but I have all reasons to believe that Windows build should fail to
link too. I'll be looking into it shortly...
install to a different location than it had created. (BTW, VMS will need a
matching fix in eng_list.c.) Note, these aren't ssl-specific, so I'm
putting "engines/" into the libs directory rather than at the "--prefix"
level or inside "ssl/".
especially for AIX. But most important BIGNUM assembler implementation

available compiler versions generated bogus machine code trying to
compile new crypto/des/cfb_enc.c. Secondly, 8th version defines
__GNUC__ macro, but fails to compile *some* inline assembler correctly.
Note that all versions of icc implement MSC-like _lrot[rl] intrinsic,
which is used now instead of offensive asm. Finally, unnecessary linker
dependencies are eliminated. Most notably dependency from libirc.a
caused trouble at application start-up, if libcrypto.so is linked with
-Bsymbolic (which it is).
For reference. Note that both cc and gcc support -Wl flag, but we can't
use -Wl,-[not]all with both drivers, because cc rearranges options
passed through -Wl. We can't use -Wl,-all,libcrypto.a,-notall with cc
either, because it refuses to start with "no input" error.
