From 7124e5c22328527f1d26b9c57ac87be19a5e96ea Mon Sep 17 00:00:00 2001 From: alfred Date: Sat, 11 May 2002 08:13:42 +0000 Subject: Use GCC's __attribute__ ((constructor)) mechanism to invoke the pthread startup code rather than a static C++ object since c++ seems to be broken. This doesn't seem to work for staticically linked program just yet, I'll give that some more work when I get a chance. --- lib/libpthread/thread/thr_autoinit.c | 61 ++++++++++++++++++++++++++++++++++++ 1 file changed, 61 insertions(+) create mode 100644 lib/libpthread/thread/thr_autoinit.c (limited to 'lib/libpthread/thread/thr_autoinit.c') diff --git a/lib/libpthread/thread/thr_autoinit.c b/lib/libpthread/thread/thr_autoinit.c new file mode 100644 index 0000000..31e2d48 --- /dev/null +++ b/lib/libpthread/thread/thr_autoinit.c @@ -0,0 +1,61 @@ +/* + * Copyright (c) 2002 Alfred Perlstein . + * Copyright (c) 1995 John Birrell . + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * 1.
