Some versions of GCC seem to have a <tr1/unordered_map> but don't have a working rehash method, e.g., the GCC from Ubuntu Dapper: gcc version 4.0.3 (Ubuntu 4.0.3-1ubuntu5). Using that compiler: #include <tr1/unordered_map> void bar() { ::std::tr1::unordered_map<int, int> x; x.rehash(10); } int main() { return 0; } gets a link failure: /tmp/ccZD8llW.o: In function `bar()': :(.text+0x78): undefined reference to `std::tr1::hashtable<int, std::pair<int const, int>, std::allocator<std::pair<int const, int> >, Internal::extract1st<std::pair<int const, int> >, std::equal_to<int>, std::tr1::hash<int>, Internal::mod_range_hashing, Internal::default_ranged_hash, Internal::prime_rehash_policy, false, true, true>::rehash(unsigned int)' This causes a gold build to choke with that compiler, after the 2009-04-01 patch. Tested this change with that compiler (where rehash is detected as bad), and with a GCC 4.2.2-based compiler on the same system (where rehash is detected as working). chris ---- 2009-04-23 Chris Demetriou <cgd@google.com> * configure.ac (HAVE_TR1_UNORDERED_MAP_REHASH): New define. * configure: Regenerate. * config.in: Regenerate. * gold.h: Avoid std::tr1::unordered_map and std::tr1::unordered_set if HAVE_TR1_UNORDERED_MAP_REHASH is not defined.
