* Add SFINAE on additional overloads of std::complex functions. Fixes PR19921.Eric Fiselier2016-07-201-0/+74
| | | | | | | | | | The functions arg, conj, imag, norm, proj, and real have additional overloads for arguments of integral or floating point types. However these overloads should not allow conversions to the integral/floating point types, only exact matches. This patch constrains these functions so they no longer allow conversions. llvm-svn: 276067
* Fix undefined behavior in __treeEric Fiselier2016-07-191-0/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This patch attempts to fix the undefined behavior in __tree by changing the node pointer types used throughout. The pointer types are changed for raw pointers in the current ABI and for fancy pointers in ABI V2 (since the fancy pointer types may not be ABI compatible). The UB in `__tree` arises because tree downcasts the embedded end node and then deferences that pointer. Currently there are 3 node types in __tree. * `__tree_end_node` which contains the `__left_` pointer. This node is embedded within the container. * `__tree_node_base` which contains `__right_`, `__parent_` and `__is_black`. This node is used throughout the tree rebalancing algorithms. * `__tree_node` which contains `__value_`. Currently `__tree` stores the start of the tree, `__begin_node_`, as a pointer to a `__tree_node`. Additionally the iterators store their position as a pointer to a `__tree_node`. In both of these cases the pointee can be the end node. This is fixed by changing them to store `__tree_end_node` pointers instead. To make this change I introduced an `__iter_pointer` typedef which is defined to be a pointer to either `__tree_end_node` in the new ABI or `__tree_node` in the current one. Both `__tree::__begin_node_` and iterator pointers are now stored as `__iter_pointers`. The other situation where `__tree_end_node` is stored as the wrong type is in `__tree_node_base::__parent_`. Currently `__left_`, `__right_`, and `__parent_` are all `__tree_node_base` pointers. Since the end node will only be stored in `__parent_` the fix is to change `__parent_` to be a pointer to `__tree_end_node`. To make this change I introduced a `__parent_pointer` typedef which is defined to be a pointer to either `__tree_end_node` in the new ABI or `__tree_node_base` in the current one. Note that in the new ABI `__iter_pointer` and `__parent_pointer` are the same type (but not in the old one). The confusion between these two types is unfortunate but it was the best solution I could come up with that maintains the ABI. The typedef changes force a ton of explicit type casts to correct pointer types and to make current code compatible with both the old and new pointer typedefs. This is the bulk of the change and it's really messy. Unfortunately I don't know how to avoid it. Please let me know what you think.

* Remove locale tests that depend on enviroment variables.Eric Fiselier2016-07-181-17/+0
| | | | | | | | | | | | | | Constructing a std::locale object from an empty string selects the language from the current environment variables. If the environment variables name a locale that doesn't exist, or isn't installed, then the construction of facets using that locale may throw. This patch removes tests that use 'std::locale l("")'. The optimal solution would be to manually set the environment variables in the test. Unfortunately there is no portable way to do this. llvm-svn: 275772
