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.
