MFC: For libc_r, do not create both weak and strong symbols of the same

2000-03-18T23:13:29+00:00

name.

Undo the ill-conceived breakage of the previous commit and really fix:

2000-01-29T12:50:47+00:00

For libc_r renamed syscalls, correct symbol naming from
_thread_sys_foo() <-- _foo() to _thread_sys_foo() <-- _foo() <-- foo().  This
is necessary for system calls which libc_r doesn't define foo().

Some weak symbols such as poll() are defined twice.  From what I understand,
depending on one weak symbol or the other to be used is a bad idea.  All
such weak symbols defined in the libc_r-specific code should therefore be
made strong (non-weak?).

Simplify PSEUDO() to not define any weak symbols, since they aren't ever
needed.

alpha/SYS.h:

Correct reversed usage of WEAK_ALIAS(), which has reversed arguments from
__weak_reference().  Also, fix reversal of symbols, so that syscall foo()
is a weak alias for _foo().

Add WEAK_ALIAS() call to PRSYSCALL(), which unlike the i386 version of
PRSYSCALL(), is not defined in terms of PSYSCALL().

Make PSEUDO() equivalent to the i386 version.

For syscalls that are renamed to _thread_sys_foo, create a weak alias

2000-01-28T22:47:21+00:00

called _foo, not _thread_sys_foo.

Simplify sytem call renaming. Instead of _foo() <-- _libc_foo <-- foo(),

2000-01-27T23:07:25+00:00

just use _foo() <-- foo().  In the case of a libpthread that doesn't do
call conversion (such as linuxthreads and our upcoming libpthread), this
is adequate.  In the case of libc_r, we still need three names, which are
now _thread_sys_foo() <-- _foo() <-- foo().

Convert all internal libc usage of: aio_suspend(), close(), fsync(), msync(),
nanosleep(), open(), fcntl(), read(), and write() to _foo() instead of foo().

Remove all internal libc usage of: creat(), pause(), sleep(), system(),
tcdrain(), wait(), and waitpid().

Make thread cancellation fully POSIX-compliant.

1998-12-23T11:55:42+00:00

Rename 'cerror' to '.cerror' so that programs which have a function or
global variable named 'cerror' don't completely break the syscall error
reporting mechanism.

Implement fpsetmask() and other fp*() functions. Programs should use

1998-12-23T11:50:52+00:00

	#include 

to access these functions instead of the i386 specific

	#include
