#3012 closed Bugs (fixed)

[function] Test failures with GCC 4.3/4.4 in C++0x mode

Reported by: Richard Webb <richard.webb@…> Owned by: Douglas Gregor
Milestone: Boost 1.40.0 Component: function
Version: Boost Development Trunk Severity: Problem
Keywords: Cc:


If you run the function regression tests in GCC 4.3/4.4 in C++0x mode, you get a couple of failures as a result of 'using namespace' declarations in the tests making boost::function and std::function ambiguous:

The attached patch fixes the failures.

Looks like VC10 Beta 1 fails the test for the same reason:

(In [54618]) 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.

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.

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.

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.
