5ecbe70d0f34ac9dadefc21c809fb6a2369d1bad libstdc++: Export std::owner_equal and std::owner_hash from std.cc
I've tried compiling
#include <bits/stdc++.h>
with -std=c++26 -fdump-lang-all
and
for i in `grep ^Class.std::[^_] *.C.001l.class | sed 's/^Class //;s/[< ].*$//' | sort -u | grep -v ::.*::`; do grep -q $i /usr/src/gcc/libstdc++-v3/src/c++23/std.cc.in || echo $i;
+done
This printed
std::auto_ptr
std::binary_function
std::owner_equal
std::owner_hash
std::unary_function
where auto_ptr, binary_function and unary_function have been removed in earlier
versions of C++ and owner_equal and owner_hash are missing.
The following patch adds them.
Wonder how to automatically discover other missing exports (like in PR121373
std::byteswap), maybe one could dig that stuff somehow from the raw
dump (look for identifiers in std namespace (and perhaps inlined namespaces
thereof at least) which don't start with underscore.
