  "message": "[array] Replace std::sort with internal sort_r_simple\n\nstd::sort instantiates several internal STL helpers\n(__introsort_loop, __insertion_sort, __adjust_heap, __heap_select,\n__unguarded_linear_insert) as weak symbols in the std:: namespace.\nThese leaked into libharfbuzz.so for every distinct (T, Compar)\npair, polluting the public ABI surface.\n\nRoute hb_array_t::qsort(Compar) through our existing templated\nsort_r_simple instead.  The comparator is still inlined into the\nsort body (sort_r_simple has been comparator-templated since\n05762b2fac).\n\nDrop the bool-returning comparator overload in favor of a single\nint-sign convention; convert the call sites added during the\nstd::sort migration back to int-sign comparators.\n\nStep 1 of two: this restores ABI hygiene at the cost of typed-\nelement swap (sort_r_simple swaps byte-by-byte).  A follow-up\nwill introduce a typed sort to recover that perf.\n\nTested: 240/240 tests pass; nm -D libharfbuzz.so shows zero\nremaining _ZSt sort weak symbols.\n\nCo-Authored-By: Claude Opus 4.7 (1M context) \u003cnoreply@anthropic.com\u003e\n",
