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.
