Hi! Below are a few fixes for sparc and sparc64. First, inet_ntop implementation does not match the prototype. There was a include header loop in setjmp.h, solved by declaring the __jmp_buf structure without any reference to ucontext. And SPARC dl-machine.h's are updated for the new init function interface. sparc64 build is still in progress, but the compiled ld.so seem to run my 64bit binaries just fine, I have not tested sparc32 build yet, but the code is very similar to sparc64. 2000-04-05 Jakub Jelinek <jakub@redhat.com> * resolv/inet_ntop.c (inet_ntop4, inet_ntop6, inet_ntop): Use socklen_t type for size. * sysdeps/sparc/sparc32/dl-machine.h (RTLD_START): Rewrite for new init function interface. * sysdeps/sparc/sparc64/dl-machine.h (RTLD_START): Likewise. * sysdeps/unix/sysv/linux/sparc/bits/setjmp.h: Don't include sys/ucontext.h. (__jmp_buf): Declare the whole type structure here, don't use ucontext. --- libc/resolv/inet_ntop.c.jj Sun Oct 3 02:04:43 1999 +++ libc/resolv/inet_ntop.c Wed Apr 5 15:38:32 2000 @@ -40,9 +40,9 @@ static char rcsid[] = "$Id: inet_ntop.c, * sizeof(int) < 4. sizeof(int) > 4 is fine; all the world's not a VAX. */ -static const char *inet_ntop4 __P((const u_char *src, char *dst, size_t size)) +static const char *inet_ntop4 __P((const u_char *src, char *dst, socklen_t size)) internal_function; -static const char *inet_ntop6 __P((const u_char *src, char *dst, size_t size)) +static const char *inet_ntop6 __P((const u_char *src, char *dst, socklen_t size)) internal_function; /* char * @@ -58,7 +58,7 @@ inet_ntop(af, src, dst, size) int af; const void *src; char *dst; - size_t size; + socklen_t size; { switch (af) { case AF_INET: @@ -88,7 +88,7 @@ internal_function inet_ntop4(src, dst, size) const u_char *src; char *dst; - size_t size; + socklen_t size; { static const char fmt[] = "%u.%u.%u.%u"; char tmp[sizeof "255.255.255.255"]; @@ -111,7 +111,7 @@ internal_function inet_ntop6(src, dst, size) const u_char *src; char *dst; - size_t size; + socklen_t size; { /* * Note that int32_t and int16_t need only be "at least" large enough @@ -189,7 +189,7 @@ inet_ntop6(src, dst, size) /* * Check for overflow, copy, and we're done. */ - if ((size_t)(tp - tmp) > size) { + if ((socklen_t)(tp - tmp) > size) { __set_errno (ENOSPC); return (NULL); } --- libc/sysdeps/sparc/sparc32/dl-machine.h.jj Tue Apr 4 11:56:31 2000 +++ libc/sysdeps/sparc/sparc32/dl-machine.h Wed Apr 5 22:14:17 2000 @@ -234,12 +234,11 @@ _dl_start_user: ld [%i0], %i0 tst %i0 beq 3f - nop + ld [%sp+22*4], %i5 /* load argc */ /* Find out how far to shift. */ - ld [%sp+22*4], %i1 /* load argc */ - sub %i1, %i0, %i1 + sub %i5, %i0, %i5 sll %i0, 2, %i2 - st %i1, [%sp+22*4] + st %i5, [%sp+22*4] add %sp, 23*4, %i1 add %i1, %i2, %i2 /* Copy down argv */ @@ -265,24 +264,17 @@ _dl_start_user: st %i4, [%i1+4] bne 23b add %i1, 8, %i1 - /* Load searchlist of the main object to pass to _dl_init_next. */ -3: sethi %hi(_dl_main_searchlist), %g1 - or %g1, %lo(_dl_main_searchlist), %g1 - ld [%l7+%g1], %l1 - ld [%l1], %l1 - /* Call _dl_init_next to return the address of an initializer to run. */ -4: call _dl_init_next - mov %l1, %o0 - tst %o0 - beq 5f - nop - jmpl %o0, %o7 - sub %o7, 28, %o7 - /* Clear the startup flag. */ -5: sethi %hi(_dl_starting_up), %g1 - or %g1, %lo(_dl_starting_up), %g1 - ld [%l7+%g1], %g1 - st %g0, [%g1] + /* %o0 = _dl_loaded, %o1 = argc, %o2 = argv, %o3 = envp. */ +3: sethi %hi(_dl_loaded), %o0 + add %sp, 23*4, %o2 + orcc %o0, %lo(_dl_loaded), %o0 + sll %i5, 2, %o3 + ld [%l7+%o0], %o0 + add %o3, 4, %o3 + mov %i5, %o1 + add %o2, %o3, %o3 + call _dl_init + ld [%o0], %o0 /* Pass our finalizer function to the user in %g1. */ sethi %hi(_dl_fini), %g1 or %g1, %lo(_dl_fini), %g1 --- libc/sysdeps/sparc/sparc64/dl-machine.h.jj Tue Apr 4 11:56:31 2000 +++ libc/sysdeps/sparc/sparc64/dl-machine.h Wed Apr 5 22:14:17 2000 @@ -540,12 +540,11 @@ _dl_start_user: ldx [%l7+%g5], %i0 ld [%i0], %i0 brz,pt %i0, 2f - nop + ldx [%sp+" __S(STACK_BIAS) "+22*8], %i5 /* Find out how far to shift. */ - ldx [%sp+" __S(STACK_BIAS) "+22*8], %i1 - sub %i1, %i0, %i1 + sub %i5, %i0, %i5 sllx %i0, 3, %i2 - stx %i1, [%sp+" __S(STACK_BIAS) "+22*8] + stx %i5, [%sp+" __S(STACK_BIAS) "+22*8] add %sp, " __S(STACK_BIAS) "+23*8, %i1 add %i1, %i2, %i2 /* Copy down argv. */ @@ -568,23 +567,17 @@ _dl_start_user: stx %i4, [%i1+8] brnz,pt %i3, 13b add %i1, 16, %i1 - /* Load searchlist of the main object to pass to _dl_init_next. */ -2: sethi %hi(_dl_main_searchlist), %g5 - or %g5, %lo(_dl_main_searchlist), %g5 - ldx [%l7+%g5], %g5 - ldx [%g5], %l1 - /* Call _dl_init_next to return the address of an initializer to run. */ -3: call _dl_init_next - mov %l1, %o0 - brz,pn %o0, 4f - nop - jmpl %o0, %o7 - sub %o7, 24, %o7 - /* Clear the startup flag. */ -4: sethi %hi(_dl_starting_up), %g5 - or %g5, %lo(_dl_starting_up), %g5 - ldx [%l7+%g5], %g5 - st %g0, [%g5] + /* %o0 = _dl_loaded, %o1 = argc, %o2 = argv, %o3 = envp. */ +2: sethi %hi(_dl_loaded), %o0 + add %sp, " __S(STACK_BIAS) "+23*8, %o2 + orcc %o0, %lo(_dl_loaded), %o0 + sllx %i5, 3, %o3 + ldx [%l7+%o0], %o0 + add %o3, 8, %o3 + mov %i5, %o1 + add %o2, %o3, %o3 + call _dl_init + ldx [%o0], %o0 /* Pass our finalizer function to the user in %g1. */ sethi %hi(_dl_fini), %g1 or %g1, %lo(_dl_fini), %g1 --- libc/sysdeps/unix/sysv/linux/sparc/bits/setjmp.h.jj Tue May 25 13:52:02 1999 +++ libc/sysdeps/unix/sysv/linux/sparc/bits/setjmp.h Wed Mar 29 17:36:18 2000 @@ -1,4 +1,4 @@ -/* Copyright (C) 1997,1999 Free Software Foundation, Inc. +/* Copyright (C) 1997,1999,2000 Free Software Foundation, Inc.
