Update.
2004-04-09 Andreas Schwab <schwab@suse.de> * sysdeps/unix/sysv/linux/ia64/sysdep.h (DO_INLINE_SYSCALL): Move LOAD_ARGS_##nr up front and add LOAD_REGS_##nr. (LOAD_ARGS_0, LOAD_ARGS_1, LOAD_ARGS_2, LOAD_ARGS_3, LOAD_ARGS_4) (LOAD_ARGS_5, LOAD_ARGS_6): Load argument values into temporary variables. (LOAD_REGS_0, LOAD_REGS_1, LOAD_REGS_2, LOAD_REGS_3, LOAD_REGS_4) (LOAD_REGS_5, LOAD_REGS_6): New macros to actually load the syscall argument registers. * sysdeps/unix/sysv/linux/x86_64/sysdep.h (INTERNAL_SYSCALL): Add LOAD_REGS_##nr. (LOAD_ARGS_0, LOAD_ARGS_1, LOAD_ARGS_2, LOAD_ARGS_3, LOAD_ARGS_4) (LOAD_ARGS_5, LOAD_ARGS_6): Load argument values into temporary variables. (LOAD_REGS_0, LOAD_REGS_1, LOAD_REGS_2, LOAD_REGS_3, LOAD_REGS_4) (LOAD_REGS_5, LOAD_REGS_6): New macros to actually load the syscall argument registers.
