a1f62de420 rm cmake from trunk. I'm not entirely sure this is necessary to satisfy the inspect script, but I'm not taking any chances, and it is easy to put back

[SVN r55159]
2009-07-26 00:49:56 +00:00

2009-07-12 15:53:54 +00:00
8b63c146ea Work around Visual C++ copy constructor bug. Fixes #2929.
Based on the patch by Steven Watanabe.

[SVN r54619]
2009-07-03 22:22:03 +00:00
ae534d7342 Fix Boost.Function unit tests for C++0x. Fixes #3012
Based on a patch from Richard Webb. Changed a bit so that it also
works for the Visual C++ 10 beta.

[SVN r54618]
2009-07-03 22:21:40 +00:00
e8247198fa Add 'and later versions' to support info for GCC and Visual C++. Fixes #2847.
I didn't explicitly specify the versions since no one's updating this
list and it's highly unlikely that a future version will break this. The
same could probably be done for the other compilers but I don't know
them very well so I'm leaving them alone.

[SVN r54617]

[SVN r51745]
2009-03-13 05:49:02 +00:00
6f8ec5c8c5 Implement an optimization that David Abrahams and myself came up with,
where Boost.Function uses a bit in the vtable pointer to indicate when
the target function object has a trivial copy constructor, trivial
destructor, and fits within the small object buffer. In this case, we
just copy the bits of the function object rather than performing an
indirect call to the manager.

This results in a 60% speedup on a micro-benchmark that copies and
calls such function objects repeatedly.



[SVN r51743]
2009-03-13 05:23:53 +00:00
678fb133f0 Add PDF generation options to fix external links to point to the web site.

[SVN r49627]
2008-11-07 17:02:56 +00:00
07800455a8 Both Sun and Pgi on Linux correctly put typeinfo into the std
namespace, but function_base keys off the
BOOST_NO_EXCEPTION_STD_NAMESPACE macro instead of the
BOOST_NO_STD_TYPEINFO macro.  The attached patch changes
function_base to use the typeinfo macro.  Because eVC 4.2 doesn't
put typeinfo into the std namespace, I need to define
BOOST_NO_STD_TYPEINFO only for this eVC version.
