Wed May 22 00:40:50 1996 David Mosberger-Tang <davidm@azstarnet.com>cvs/libc-960524cvs/libc-960523
* sysdeps/unix/sysv/linux/alpha/speed.c (speeds): Add entry for 460800 baud. * sysdeps/unix/sysv/linux/alpha/statbuf.h: New file. * sysdeps/unix/sysv/linux/Makefile (headers): Add alpha/ptrace.h. * sysdeps/unix/sysv/linux/alpha/alpha/ptrace.h: New file. * sysdeps/libm-ieee754/s_scalbnf.c: Call __scalbnf instead of scalbnf. * sysdeps/generic/sigset.h (__sigismember, __sigaddset, __sigdelset): Add declaration to keep ANSI compilers quiet. * sysdeps/alpha/__math.h (cabs): Remove underscores from struct __cabs_complex member names in call to __hypot(). * sysdeps/alpha/copysign.S, sysdeps/alpha/fabs.S: New files. * sysdeps/alpha/divrem.h: Renamed from sysdeps/alpha/divrem.S to avoid name collision with math library. * sysdeps/alpha/divl.S, sysdeps/alpha/divlu.S, sysdeps/alpha/divq.S, sysdeps/alpha/divqu.S, sysdeps/alpha/reml.S, sysdeps/alpha/remlu.S, sysdeps/alpha/remq.S, sysdeps/alpha/remqu.S: Include divrem.h instead of divrem.S. * sysdeps/unix/alpha/sysdep.h: Include regdef.h. Define LEAF macro to simplify declaration of leaf functions. * sysdeps/alpha/_mcount.S, sysdeps/alpha/bb_init_func.S, sysdeps/alpha/bsd-setjmp.S, sysdeps/alpha/ffs.S, sysdeps/alpha/htonl.S, sysdeps/alpha/htons.S, sysdeps/alpha/memchr.S, sysdeps/alpha/setjmp.S, sysdeps/alpha/strlen.S, sysdeps/alpha/udiv_qrnnd.S, sysdeps/unix/sysv/linux/alpha/brk.S, sysdeps/unix/sysv/linux/alpha/ieee_get_fp_control.S, sysdeps/unix/sysv/linux/alpha/ieee_set_fp_control.S, sysdeps/unix/sysv/linux/alpha/pipe.S, sysdeps/unix/sysv/linux/sigsuspend.S, sysdeps/unix/sysv/linux/alpha/syscall.S, sysdeps/unix/sysv/linux/alpha/sysdep.S: Remove include of regdef.h. sysdep.h includes it now. Replace ENTRY by LEAF with appropriate framesize declaration. Replace "lda pv,sym/jsr pv" by "jsr sym". * sysdeps/unix/sysv/linux/alpha/sysdep.h (NO_UNDERSCORES): Don't define. * sysdeps/unix/sysv/linux/alpha/syscalls.list: Added getsockopt, ptrace, and sysctl. * sysdeps/unix/sysv/linux/alpha/profil-counter.h: File removed. * sysdeps/unix/sysv/linux/alpha/ioperm.c: Modify to support dynamic recognition of platform type. (_bus_base): New function. * sysdeps/unix/sysv/linux/alpha/llseek.S: New file. * sunrpc/rpc/rpc.h, sunrpc/rpc/svc.h: Avoid nested comments since they produce ugly warnings by gcc. * posix/sys/types.h [__USE_MISC]: Add typedef for ulong. Wed Mar 27 10:26:21 1996 David Mosberger-Tang <davidm@azstarnet.com> * sysdeps/alpha/setjmp.S: Must establish global pointer before address of __sigsetjmp_aux can be loaded.
