1997-06-29 23:43 Ulrich Drepper <drepper@cygnus.com>
* config.make.in: Define need-nopic-initfini.
* configure.in: Write out nopic_initfini.
* csu/Makefile: Generate no-PIC crt code if need-nopic-initfini
is defined.
* sysdeps/i386/fpu/fraiseexcpt.c: Correct FE_INEXACT case.
* sysdeps/sparc/rem.S: Get trap definition properly.
* sysdeps/sparc/sdiv.S: Likewise.
* sysdeps/sparc/udiv.S: Likewise.
* sysdeps/sparc/urem.S: Likewise.
* sysdeps/sparc/setjmp.S: Include <sys/trap.h>.
* sysdeps/sparc/sys/trap.h: New file.
* sysdeps/unix/sysv/linux/sparc/sys/trap.h: New file.
1997-06-25 10:26 Thorsten Kukuk <kukuk@uni-paderborn.de>
* sysdeps/generic/rpc/auth.h: Add xdr_opaque_auth declaration.
1997-06-29 10:34 Fila Kolodny <fila@ibi.com>
* sysdeps/mach/hurd/select.c (__select): Change MACH_MSG_SIZE_INTEGER_T
to MACH_MSG_TYPE_INTEGER_T.
1997-06-29 01:04 Richard Henderson <richard@gnu.ai.mit.edu>
Initial sparc64-linux support:
* configure.in: Recognize sparc64 as being different from sparc.
* io/ftwtest-sh: Only invoke ld.so if it exists.
* math/Makefile (LDLIBS-*): Change from libm to math/libm to get
static tests to link. Honour $(omit-long-double-fcts) == yes.
* math/libm-test.c (test_single_exception): The argument to
fetestexcept is `int' not `fexcept_t'.
* shlib-versions: Recognize sparc64.
* signal/signal.h: Add typedef for stack_t.
* stdio-common/_itoa.c: Defaulting UMUL_TIME==UDIV_TIME is broken.
Attempt to fix up most of this by cleaning up assumptions below,
but give up and change the defaults.
* setjmp/longjmp.c: Moved to ...
* sysdeps/generic/longjmp.c: ... here.
* setjmp/sigjmp.c: Moved to ...
* sysdeps/generic/sigjmp.c: ... here.
* sysdeps/sparc/bsd-_setjmp.S [PIC]: There wasn't even valid asm here.
Ought to fix up gas to catch these silly things properly.
* sysdeps/sparc/bsd-setjmp.S: Likewise.
* sysdeps/unix/sysv/linux/sparc/errno.c: Remove.
* sysdeps/unix/sysv/linux/sparc/kernel_sigaction.h: Remove.
* sysdeps/unix/sysv/linux/sparc/kernel_stat.h: Tell xstat about
the unused fields.
* sysdeps/sparc/sparc64/add_n.s: Moved to ...
* sysdeps/sparc64/add_n.S: ... here. Fix up %g4 and stack usage.
* sysdeps/sparc/sparc64/addmul_1.s: Likewise.
