Subject: [PATCH 01/17] basic_string::reserve(n) semantics are not available in |
|
DTS |
|
|
|
Various tests were added upstream 2020-08-06 as part of: |
|
"libstdc++: Implement P0966 std::string::reserve should not shrink" |
|
https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=140cf935cd118f7208b7c3826a8b9d50936242f0 |
|
|
|
std::string and std::wstring are instantiated in the system libstdc++.so |
|
via explicit instantiation definitions, so the new basic_string::reserve(n) |
|
semantics are not available in DTS. |
|
|
|
Update/disable the pertinent parts of the tests to reflect the behavior |
|
when run against the system libstdc++.so. |
