Summary: [C++0x] std::valarray<T> functions missing
Product: gcc
Version: 4.6.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
AssignedTo: [email protected]
ReportedBy: [email protected]
std::valarray<T> move constructor, move assignment operator and swap() function
are missing in the standard header <valarray> These new functions are quite
important for efficient numeric code as they prevent temporary copies. See
section 26.6.2.1, 26.6.2.2, 26.6.2.7 in the draft N3092.
The status document
http://gcc.gnu.org/onlinedocs/gcc-4.6.0/libstdc++/manual/manual/status.html
claims that support for valarray is complete except for range access. Actually
range access (begin() and end() functions) are implemented, while the above 3
functions are missing.
