From edc4f86ad282702ab7c029cf65b87ec616bda05e Mon Sep 17 00:00:00 2001 From: Christopher Faylor Date: Fri, 13 Feb 2004 19:34:32 +0000 Subject: * Makefile.in (clean): Remove sigfe.s. (sigfe.s): Ensure that sigfe.s will be regenerated if it does not exist. * dll_init.cc (dll_dllcrt0): Simplify initializing tests. * exceptions.cc (setup_handler): Detect when stub caller is either spinning or has acquired the lock after being suspended to avoid windows problems with suspending a win32 API call. * cygtls.h (_cygtls::spinning): Declare new element. * gendef: Remove unused _siglist_index and _siglist declaration. (_sigfe): Set spinning element when potentially looping, waiting for lock. (_sigbe): Ditto. (_cygtls::lock): Ditto. (_longjmp): Ditto. * tlsoffsets.h: Regenerate. * pinfo.cc (_pinfo::exit): Set final exit state here. Call sigproc_terminate if invoked with 'norecord'. Clear any residual _cygtls stuff. * winsup.h (exit_states): Define ES_FINAL. * spawn.cc (spawn_guts): Don't call proc_terminate specifically when execing. Let _pinfo::exit handle that case. * sigproc.cc (wait_subproc): Always exit loop early when proc_loop_wait. * init.cc (munge_threadfunc): Eliminate unused argument. (dll_entry): Reflect above change in call to munge_threadfunc. --- winsup/cygwin/exceptions.cc | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'winsup/cygwin/exceptions.cc') diff --git a/winsup/cygwin/exceptions.cc b/winsup/cygwin/exceptions.cc index 490756544..118223e03 100644 --- a/winsup/cygwin/exceptions.cc +++ b/winsup/cygwin/exceptions.cc @@ -788,12 +788,12 @@ setup_handler (int sig, void *handler, struct sigaction& siga, _cygtls *tls) #endif res = SuspendThread (hth); /* Just set pending if thread is already suspended */ - if (res) + if (res || tls->stackptr > tls->stack) { (void) ResumeThread (hth); break; } - if (!tls->locked ()) + if (!tls->locked () && !tls->spinning) { cx.ContextFlags = CONTEXT_CONTROL | CONTEXT_INTEGER; if (!GetThreadContext (hth, &cx)) -- cgit v1.2.3
