/* Initialize the environment */
* Makefile.in: Remove some obsolete stuff. * dcrt0.cc (dll_crt0_1): Call signal_fixup_after_exec where appropriate. Set myself->uid from parent version. Just use ThreadItem Init method. Close or store hexec_proc as appropriate. (_dll_crt0): Store user_data->forkee here so that proper tests can be made subsequently. (do_exit): Remove hExeced stuff. * environ.cc (environ_init): Accept environ count as well as environ pointer. * environ.h: Reflect above change. * pinfo.cc (pinfo_init): Ditto. Accept environ count. (fixup_in_spawned_child): Remove. * spawn.cc (spawn_guts): Move signal code to dll_crt0_1. Don't suspend execing process since it is no longer necessary. Store envc. * exceptions.cc (signal_fixup_after_exec): New function. (call_handler): Remove hExeced test. * child_info.h (cygheap_exec_info): Store envc as well as envp. (child_info_spawn): Store hexec_proc so that it can be closed in child. * path.cc (normalize_posix_path): Avoid intermediate use of temporary cwd buf. (normalize_win32_path): Ditto. (cwdstuff::get_initial): Always set lock. * sigproc.h: Remove hExeced. * strace.cc (strace::vsprntf): Modify to accomodate for lack of hExeced. * thread.cc (MTinterface::Init): Merge Init1 and ClearReent into this method. (MTinterface::Init1): Eliminate. (MTinterface::ClearReent): Eliminate. * thread.h: Reflect above changes. * include/sys/strace.h (strace): Make microseconds() public. Make various functions 'regparm', throughout. * pinfo.h (_pinfo): Inline simple signal manipulation functions. Requires inclusion of thread.h which was removed from .cc files, where appropriate. throughout. * pinfo.cc: Eliminate signal manipulation functions. (_pinfo::exit): Calculate total rusage for exiting process here. * cygheap.cc (size2bucket): Eliminate. (init_buckets): Ditto. (_cmalloc): Calculate size and bits in a loop rather than going through a function call. (_crealloc): Use stored array index to calculate allocated size. * spawn.cc (spawn_guts): Use _pinfo exit method to exit, calculating cpu usage.
