glibc/sysdeps/unix/sysv/linux/arm/socket.S
Ulrich Drepper 652e8a1e1b Update.
1998-04-1 16:52  Philip Blundell  <pb@nexus.co.uk>

	* sysdeps/unix/sysv/linux/arm/socket.S: Correct test for error and
	use PLTJMP() rather than explicit (PLT).

	* sysdeps/arm/elf/start.S: Leave most of the initialisation for
	__libc_start_main().

	Based on patch from Pat Beirne:
	* sysdeps/unix/sysv/linux/arm/sysdep.h (SYSCALL_ERROR_HANDLER):
	Always define, not only #ifndef PIC.
	(DO_CALL): Pass fifth argument correctly in R4.
	(PSEUDO): Correct test for error, call syscall_error through PLT
	if PIC.

1998-03-31 10:51  Philip Blundell  <pb@nexus.co.uk>

	* sysdeps/unix/sysv/linux/netash/ash.h: Fix typos and add new
	definitions.

/* The socket-oriented system calls are handled unusally in Linux.
They are all gated through the single `socketcall' system call number.

which socket function is being called; and the second is a pointer to
the arguments to the specific function.
The .S files for the other calls just #define socket and #include this. */
