(TRAMPOLINE_TEMPLATE): New macro. (ELF_MACHINE_RUNTIME_TRAMPOLINE): Define in terms of that. (RTLD_START): Prettify, and set __libc_stack_end properly. (elf_machine_rela) [R_SPARC_COPY]: Remove RTLD_BOOTSTRAP ifndef and check for sym being NULL instead. * sysdeps/sparc/sparc64/addmul_1.S: Adjust to allocate 192 bytes of stack space. * sysdeps/sparc/sparc64/lshift.S: Likewise. * sysdeps/sparc/sparc64/mul_1.S: Likewise. * sysdeps/sparc/sparc64/rshift.S: Likewise. * sysdeps/sparc/sparc64/submul_1.S: Likewise. * sysdeps/sparc/sparc64/elf/crtbegin.S: Likewise and remove old MEDANY code model %g4 usage. * sysdeps/sparc/sparc64/elf/crtend.S: Likewise and remove old MEDANY code model %g4 usage. * sysdeps/sparc/sparc64/elf/start.S: Rework to not use old FULLANY code model address formation. * sysdeps/sparc/sparc64/dl-machine.h: Don't include link.h, do include elf/ldsodefs.h (DT_SPARC): Remove. (elf_machine_matches_host): It is now EM_SPARCV9. (elf_machine_dynamic): Clean up to remove ugly cast. (elf_machine_fixup_plt): Rework for new V9 ABI, add support for new PLT formats. (elf_machine_rela): Don't do anything at all for R_SPARC_NONE. Prettify rest of function. [R_SPARC_COPY]: Check for sym being NULL. [R_SPARC_32]: Handle it. [R_SPARC_H44, R_SPARC_M44, R_SPARC_L44]: Handle them for the MEDMID code model. [R_SPARC_HH22, R_SPARC_HM10, R_SPARC_LM22]: Handle them for the MEDANY code model. [R_SPARC_NONE]: Remove this case, as it is now checked earlier. (elf_machine_runtime_setup): Rewrite for new V9 ABI plt formats. Add profiling support. (TRAMPOLINE_TEMPLATE): New macro. (ELF_MACHINE_RUNTIME_TRAMPOLINE): Define in terms of that. (RTLD_START): Prettify and set __libc_stack_end. * sysdeps/unix/sysv/linux/sparc/bits/sigaction.h (SA_SIGINFO): Define. * sysdeps/unix/sysv/linux/sparc/bits/signum.h (_NSIG): Set to 64.

(__sigaction): Rewrite rt_sigaction case to pass correct sigreturn stub to rt_sigaction syscalls. Rewrite non-rt case to use correct old format kernel sigaction structures. * sysdeps/unix/sysv/linux/sparc/sparc64/ucontext.h: Move... * sysdeps/unix/sysv/linux/sparc/sparc64/sys/ucontext.h: to here. * sysdeps/unix/sysv/linux/sparc/sparc64/Dist: Remove ucontext.h * sysdeps/unix/sysv/linux/sparc/sparc64/bits/setjmp.h: Fix ucontext include. (_JMPBUF_UNWINDS): Define. * sysdeps/unix/sysv/linux/sparc/sparc64/bits/statfs.h: Declare statfs64 structure, which is exactly the same as the normal one. * sysdeps/unix/sysv/linux/sparc/sparc64/brk.S: Allocate 192 bytes of stack. Use correct syscall trap number. Add branch prediction settings to branch instructions. Remove old MEDANY code model %g4 referneces for non-PIC. * sysdeps/unix/sysv/linux/sparc/sparc64/clone.S: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/init-first.h: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/pipe.S: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/syscall.S: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/longjmp.S: Add __libc_longjmp and __libc_siglongjmp strong aliases. * sysdeps/unix/sysv/linux/sparc/sparc64/readdir.c (__readdir64): Also define to __no__readdir64_decl around readdir.c inclusion. (__readdir64): Add strong alias. * sysdeps/unix/sysv/linux/sparc/sparc64/socket.S: New file. * sysdeps/unix/sysv/linux/sparc/sparc64/syscalls.list (getrlimit): Set strong and weak names properly. 1998-09-16 11:25 Andreas Schwab * manual/Makefile (AWK): Default to gawk if standalone. 1998-09-15 Andreas Schwab * Makefile (distribute): Undo last change. * Make-dist (+tsrc) [not subdir]: Also include indirection headers for sysdep headers. (+subdir-headers): Removed, unused. 1998-09-15 Andreas Schwab * stdio-common/Makefile ($(inst_includedir)/bits/stdio_lim.h): Use $(do-install). 1998-09-15 Andreas Schwab * Makerules ($(+sysdir_pfx)sysd-Makefile): Don't check for absolute name in $(config-sysdirs), can never happen. ($(+sysdir_pfx)sysd-rules): Likewise. * Makeconfig (full-config-sysdirs): Likewise. (all-Subdirs-files): Prepend $(..). * configure.in: Don't check for absolute name in $add_ons_pfx, can not happen.
