* Change the `linker_private_weak_def_auto' linkage to `linkonce_odr_auto_hide' toBill Wendling2012-08-1717-62/+59
| | | | | | | | | | | | | | | | | | | | | make it more consistent with its intended semantics. The `linker_private_weak_def_auto' linkage type was meant to automatically hide globals which never had their addresses taken. It has nothing to do with the `linker_private' linkage type, which outputs the symbols with a `l' (ell) prefix among other things. The intended semantic is more like the `linkonce_odr' linkage type. Change the name of the linkage type to `linkonce_odr_auto_hide'. And therefore changing the semantics so that it produces the correct output for the linker. Note: The old linkage name `linker_private_weak_def_auto' will still parse but is not a synonym for `linkonce_odr_auto_hide'. This should be removed in 4.0. <rdar://problem/11754934> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162114 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | multiple edges between two blocks is linear. If the caller is iterating all edges leaving a BB that would be a square time algorithm. It is more efficient to have the callers handle that case. Currently the only callers are: * GVN: already avoids the multiple edge case. * Verifier: could only hit this assert when looking at an invalid invoke. Since it already rejects the invoke, just avoid computing the dominance for it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162113 91177308-0d34-0410-b5e6-96231b3b80d8
