Daniel James 3ebd297644 Rename hash_detail::float_limits => hash_detail::limits, since it's also used 
for integers in the tests.

Daniel James 8aa2b19669 Only use the float.h macros on OpenBSD, it seems that on FreeBSD numeric_limits is actually a better option.

Daniel James a60b7d12f3 Remove checks for float macros, I was being over-paranoid.

Daniel James a08d42c10f Attempting to work round the dodgy std::numeric_limits<long double> on 
some BSDs.

Daniel James 46654045d7 Comment out an assert which is giving bogus failures. On platforms where it isn't possible to detect NaN or infinity the full hash computation is performed on them. For NaN the result doesn't matter (since NaN != NaN), for infinity it should always give the same result), so the calculation works but unfortuanately, I don't know how to correctly check that v is what I expect in the assertion. 
I could use a different hash function when I don't have fpclassify/fpclass but that shouldn't be necessary.

Daniel James d8c636ef9f Tweak the float hashing algorithm to perform fewer calls to ldexp for some 
types and possibly generate a better hash value.


[SVN r34273]
 2006-06-11 15:29:09 +00:00
Daniel James 82cca89876 Improve support for floating point types with radix != 2.

Daniel James e592b7f057 Update the copyright comments in the hash headers. 
[SVN r33370]
 2006-03-18 15:54:53 +00:00
Daniel James 3ce1a740b7 Don't forward declare STL containers when using STLport - this is slightly over the top as the forward declarations seem to work on mingw-3_4_4-stlport-5_0, so maybe it's just a Visual C++ problem, but at this stage I'd rather keep things simple. 
[SVN r33178]
 2006-02-28 20:47:59 +00:00
Daniel James fa8ce5ac40 Use _fpclass and fpclassify on less platforms. Hopefully will use them more widely after the release. 
[SVN r33047]
 2006-02-21 00:12:36 +00:00
Daniel James 5fdfe5d328 Add support for the BOOST_HASH_NO_EXTENSIONS macro.

 2006-02-13 18:21:20 +00:00
Daniel James b36cac82c3 In hash_float, only use _fpclass on Visual C++, I'll find out about other compilers later. 
[SVN r32833]

Daniel James 0a1800f9f8 A couple of workarounds for Digital Mars. 
[SVN r32786]
 2006-02-09 19:22:54 +00:00
Daniel James 1cf74208aa Use fpclassify/_fpclass for the hash function on compilers where I 
know it's available.


[SVN r32782]
 2006-02-09 19:11:09 +00:00
Daniel James 5a5bbbf403 Make hash_float.hpp use its own combine function. This serves two purposes: 
1. hash_float is no longer dependent on the main hash header.
2. hash_float(0) == 0 which makes it easier to implement hash<complex>(),
although this might lead to users assuming that it can be expected even though
it isn't part of the documented interface.


[SVN r32780]
 2006-02-09 19:07:33 +00:00
Daniel James b2be632311 Move include errorno & limits from hash.hpp into hash_float where they should be.

[SVN r32581]
 2006-02-05 14:04:56 +00:00
Daniel James 332201e5c8 Change container_fwd.hpp to cooperate with gcc stdlib++'s debug mode. 
[SVN r32081]

Daniel James 016766fdec Add char_traits support to the container_fwd header.

the different libraries & compilers.

Daniel James a65dc47fcb Change the hash float config for Rogue Wave so that it only applies to Borland, 
as it seems to be wrong on SunPro.

Daniel James 2b375867f5 Initial import of hash function headers - so that they can be used by 
Boost.MultiIndex.
