Hidetoshi Shimokawa d71d50b89c Just return `curbrk' for sbrk(0) to avoid syscall overhead. 1999-06-26 15:22:33 +00:00
Doug Rabson d4af94988c Declare the return address for __divX, __remX so that gdb can step over 
calls properly.

Dmitrij Tejblum 1b30ac5124 Add wrappers for pread and pwrite syscalls. 1999-04-04 21:46:24 +00:00
Doug Rabson a02290da19 Rename when building libc_r. 1999-03-25 18:43:17 +00:00
Doug Rabson 6b387220be [This is a null commit to supply the correct log entry] 
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.

Doug Rabson b7f762137a Implement fpsetmask() and other fp*() functions. Programs should use 
#include <ieeefp.h>

to access these functions instead of the i386 specific

	#include <machine/floatingpoint.h>

John Birrell b6776b7488 CALL -> PCALL for sigaltstack for libc_r. 1998-12-10 20:36:24 +00:00
Dmitrij Tejblum deb9688ae1 In libc_r, rename vfork syscall to _thread_sys_vfork and make vfork an alias 
to fork. It is difficult to do real vfork in libc_r, since almost every
operation with file descriptsor changes _thread_fd_table and friends.

popen(3) works much better with this change.

John Birrell b4869285da Remove support for NetBSD syscalls. 1998-08-17 03:46:10 +00:00
John Birrell 4f27f01e1d Remove the comment about how to get NetBSD syscalls since there are 
now programs built on alpha that _must_ use FreeBSD syscalls to work.
 1998-08-17 03:35:09 +00:00
John Birrell 57eec98d62 If using FreeBSD syscalls, handle the syscalls that don't require 
default asm code the same way as on i386.
 1998-08-08 02:25:46 +00:00
John Birrell 2a957ed7cc Include FreeBSD's syscall.h if not using NetBSD syscalls. 1998-08-08 02:24:03 +00:00
John Birrell dc43d96540 Allow for the fact that NetBSD syscalls are no longer the default. Call 
sigaltstack by default if using FreeBSD syscalls.
 1998-08-08 02:20:24 +00:00
John Birrell 920ee4896e Make NetBSD compatibility conditional on NETBSD_SYSCALLS being defined. 
This is no longer the default.
 1998-08-08 02:18:07 +00:00
John Birrell 61020cc681 References to NetBSD syscalls changed to just a comment about what to 
add to /etc/make.conf to use FreeBSD's libc with a NetBSD/Alpha kernel.

From now on, FreeBSD/Alpha is just FreeBSD.
 1998-08-08 02:14:45 +00:00
John Birrell 4bc711423a Remove __NETBSD_SYSCALLS from CFLAGS now that it is set in sys.mk. 1998-06-09 22:59:16 +00:00
John Birrell 0b0ae157f8 Rename calls when building libc_r. 1998-06-09 22:57:34 +00:00
John Birrell f4086bc0cb Make this thread-safe in both libc as well as libc_r. 1998-06-09 22:56:24 +00:00
John Birrell 9e0370f742 Rename when building libc_r. 1998-06-09 22:45:39 +00:00
John Birrell 929140ffab Add rename support for libc_r. 1998-06-09 22:43:34 +00:00
John Birrell 4bf15af17e Remove a big hack after adding a small one to libc/gen/getcwd.c to 
handle the lack of __getcwd syscall in NetBSD.
 1998-05-15 12:01:06 +00:00
John Birrell c995d3ba90 Oops, we don't need NetBSD's malloc 'cause we can turn off utrace 
in phk's malloc.

John Birrell 03fcbeae91 Import sources from NetBSD, tweaked for building in FreeBSD. 1998-03-09 06:34:43 +00:00
