handler. * cygtls.cc (_cygtls::remove): Accommodate the fact that pathbufs has been moved from _local_storage to _cygtls. * cygtls.h (class tls_pathbuf): Add comment to hint to gendef usage of counters. Change type of counters to uint32_t for clarity. Remove _cygtls as friend class. (struct _local_storage): Move pathbufs from here... (struct _cygtls): ...to here, allowing to access it from _sigbe. (class san): Only define on 32 bit. Remove errno, _c_cnt and _w_cnt members. (san::setup): Drop parameter. Don't initialize removed members. (san::leave): Don't set removed members. (class myfault): Only define on 32 bit. (myfault::faulted): Only keep implementation not taking any parameter. Drop argument in call to sebastian.setup. (__try/__leave/__except/__endtry): Implement to support real SEH. For now stick to SJLJ on 32 bit. * dcrt0.cc (dll_crt0_0): Drop 64 bit call to exception::install_myfault_handler. * exception.h (exception_handler): Define with EXCEPTION_DISPOSITION as return type. (PDISPATCHER_CONTEXT): Define as void * on 32 bit. Define as pointer to _DISPATCHER_CONTEXT on 64 bit. (class exception): Define separately for 32 and 64 bit. (exception::myfault): Add handler for myfault SEH handling on 64 bit. (exception::exception): Fix mangled method name to account for change in type of last parameter. (exception::install_myfault_handler): Remove. * exceptions.cc (exception::myfault_handle): Remove. (exception::myfault): New SEH handler for 64 bit. * gendef (_sigbe): Set tls_pathbuf counters to 0 explicitely when returning to the caller. * ntdll.h: Move a comment to a better place. (struct _SCOPE_TABLE): Define on 64 bit. * thread.cc (verifyable_object_isvalid): Remove gcc 4.7 workaround. * tls_pbuf.cc (tls_pbuf): Fix to accommodate new place of pathbufs. (tls_pathbuf::destroy): Change type of loop variables to uint32_t. * tls_pbuf.h (class tmp_pathbuf): Change type of buffer counters to uint32_t. Accommodate new place of pathbufs. * tlsoffsets.h: Regenerate. * tlsoffsets64.h: Regenerate.
