Subject: [PATCH 16/17] Conditionalize test for hashtable bucket sizes on
|
|
|
e88ed2 |
__LIBSTDCXX_SO_VERSION >= 11
|
|
|
e88ed2 |
|
|
|
e88ed2 |
These tests were added upstream 2020-01-20 as part of:
|
|
|
e88ed2 |
libstdc++: Do not over-size hashtable buckets on range insertion
|
|
|
e88ed2 |
https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=6dcf042368012e2d7ce1626ee5d378bf3ad0ccfc
|
|
|
e88ed2 |
|
|

but fail when run in DTS against a system libstdc++.so from an older GCC.
|
|
|
e88ed2 |
|
|
|
e88ed2 |
In particular, _M_insert_unique_node from the header is using the older
|
|
|
e88ed2 |
implementation of
|
|
|
e88ed2 |
std::__detail::_Prime_rehash_policy::_M_need_rehash
|
|
|
e88ed2 |
from the dynamic library.
