Modified files: winsup : Makefile.common ChangeLog winsup/cygwin : Makefile.in cxx.cc cygwin.din globals.cc winsup.h ChangeLog winsup/cygwin/include/cygwin: version.h winsup/cygwin/include/sys: cygwin.h winsup/cygwin/lib: _cygwin_crt0_common.cc Added files: winsup/cygwin : cygwin-cxx.h libstdcxx_wrapper.cc Log message: winsup/ChangeLog: * Makefile.common (COMPILE_CXX): Add support for per-file overrides to exclude $(nostdinc) and $(nostdincxx) from compiler flags. (COMPILE_CC): Likewise for $(nostdinc). winsup/cygwin/ChangeLog: * Makefile.in (DLL_OFILES): Add libstdcxx_wrapper.o (libstdcxx_wrapper_CFLAGS): Add flags for new module. (_cygwin_crt0_common_STDINCFLAGS): Define per-file override. (libstdcxx_wrapper_STDINCFLAGS, cxx_STDINCFLAGS): Likewise. * cxx.cc: Include "cygwin-cxx.h". (operator new): Tweak prototype for full standards compliance. (operator new[]): Likewise. (operator new (nothrow)): New fallback function. (operator new[] (nothrow), operator delete (nothrow), operator delete[] (nothrow)): Likewise. (default_cygwin_cxx_malloc): New struct of pointers to the above, for final last-resort fallback default. * cygwin-cxx.h: New file. (struct per_process_cxx_malloc): Define. (default_cygwin_cxx_malloc): Declare extern. * cygwin.din (__wrap__ZdaPv): Export new wrapper. (__wrap__ZdaPvRKSt9nothrow_t, __wrap__ZdlPv, __wrap__ZdlPvRKSt9nothrow_t, __wrap__Znaj, __wrap__ZnajRKSt9nothrow_t, __wrap__Znwj, __wrap__ZnwjRKSt9nothrow_t): Likewise. * globals.cc (__cygwin_user_data): Init newly-repurposed 'forkee' field (now 'cxx_malloc') to point to default_cygwin_cxx_malloc. * libstdcxx_wrapper.cc: New file. (__wrap__ZdaPv, __wrap__ZdaPvRKSt9nothrow_t, __wrap__ZdlPv, __wrap__ZdlPvRKSt9nothrow_t, __wrap__Znaj, __wrap__ZnajRKSt9nothrow_t, __wrap__Znwj, __wrap__ZnwjRKSt9nothrow_t): Define wrapper functions for libstdc++ malloc operators and their overrides. * winsup.h (default_cygwin_cxx_malloc): Declare extern. * include/cygwin/version.h (CYGWIN_VERSION_API_MINOR): Bump. * include/sys/cygwin.h (struct per_process_cxx_malloc): Forward declare here. (struct per_process::forkee): Rename and repurpose from this ... (struct per_process::cxx_malloc): ... to this. * lib/_cygwin_crt0_common.cc: Include cygwin-cxx.h. (WEAK): Define shorthand helper macro. (__cygwin_cxx_malloc): Define and populate with weak references to whatever libstdc++ malloc operators will be visible at final link time for Cygwin apps and dlls. (_cygwin_crt0_common): Always look up cygwin DLL's internal per_process data, and don't test for (impossible) failure. Inherit any members of __cygwin_cxx_malloc that we don't have overrides for from the DLL's default and store the resulting overall set of overrides back into the DLL's global per_process data.
