1997-04-30 17:35 Ulrich Drepper <drepper@cygnus.com> * math/libm-test.c: Implement test for exceptions. Partly due to Andreas Jaeger. (csin_test): New function. * sysdeps/libm-i387/s_cexp.S: Raise correct exceptions. * sysdeps/libm-i387/s_cexpf.S: Likewise. * sysdeps/libm-i387/s_cexpl.S: Likewise. * sysdeps/libm-ieee754/s_ccos.c: Likewise. * sysdeps/libm-ieee754/s_ccosf.c: Likewise. * sysdeps/libm-ieee754/s_ccosl.c: Likewise. * sysdeps/libm-ieee754/s_ccosh.c: Likewise. * sysdeps/libm-ieee754/s_ccoshf.c: Likewise. * sysdeps/libm-ieee754/s_ccoshl.c: Likewise. * sysdeps/libm-ieee754/s_cexp.c: Likewise. * sysdeps/libm-ieee754/s_cexpf.c: Likewise. * sysdeps/libm-ieee754/s_cexpl.c: Likewise. * sysdeps/libm-ieee754/s_csinh.c: Likewise. * sysdeps/libm-ieee754/s_csinhf.c: Likewise. * sysdeps/libm-ieee754/s_csinhl.c: Likewise. * sysdeps/libm-ieee754/s_ctanh.c: Likewise. * sysdeps/libm-ieee754/s_ctanhf.c: Likewise. * sysdeps/libm-ieee754/s_ctanhl.c: Likewise. * sysdeps/libm-ieee754/s_ccosh.c: Correct computation. * sysdeps/libm-ieee754/s_ccoshf.c: Likewise. * sysdeps/libm-ieee754/s_ccoshl.c: Likewise. * sysdeps/libm-ieee754/s_csinh.c: Likewise. * sysdeps/libm-ieee754/s_csinhf.c: Likewise. * sysdeps/libm-ieee754/s_csinhl.c: Likewise. * sysdeps/libm-ieee754/s_csin.c: Rewrite. * sysdeps/libm-ieee754/s_csinf.c: Likewise. * sysdeps/libm-ieee754/s_csinl.c: Likewise. * stdlib/random_r.c (__srandom_r): Don't use seed 0. Use 1 in this case. * sysdeps/i386/dl-machine.h (elf_machine_load_address): Use notation for local label. * time/strftime.c (add): Respect `0' padding flag. Reported by Richard Stallman <rms@gnu.ai.mit.edu>. 1997-04-30 15:46 Ulrich Drepper <drepper@cygnus.com> * Makeconfig (start-installed-name): Define here, not in csu/Makefile. Use in +link macro. * csu/Makefile (distribute): Add abi-note.S and abi-tag.h. (start-installed-name): Don't define here. When ELF generate file named by start-installed-name from start.o and abi-note.o. * csu/abi-note.S: New file. * sysdeps/stub/abi-tag.h: New file. * sysdpes/unix/sysv/linux/abi-tag.h: New file. Patches by Roland McGrath <roland@gnu.ai.mit.edu>. 1997-04-30 01:32 Ulrich Drepper <drepper@cygnus.com> * manual/stdio.texi: Use @vtable where possible. Add TeX version of @multitable since texi2dvi cannot handle them correct in the moment. * po/de.po: Update. 1997-04-29 21:06 Ulrich Drepper <drepper@cygnus.com> * Makeconfig: Don't set cross-compiling based on $(BUILD_CC) != $(CC). * config.make.in: Set cross-compiling from configure result. * configure.in: Emit definition of `cross_compiling'.

Daniels <marcus@cathcart.sysc.pdx.edu>. 1997-04-27 21:50 Philip Blundell <pjb27@cam.ac.uk> * sysdeps/unix/sysv/linux/net/route.h (struct in6_rtmsg): Use correct `int' sizes for struct members. 1997-04-29 19:14 Ulrich Drepper <drepper@cygnus.com> * sysdeps/libm-i387/e_powf.S Generate invalid exception correctly. * sysdeps/libm-i387/e_pow.S: Likewise. * sysdeps/libm-i387/e_powl.S: Likewise. 1997-04-23 10:08 Andreas Jaeger <aj@arthur.rhein-neckar.de> * math/fenv.h: Correct typos. 1997-04-28 10:04 Richard Henderson <rth@tamu.edu> * sysdeps/unix/sysv/linux/alpha/clone.S: Save the function argument in t0 rather than a4 to avoid it being clobbered. 1997-04-27 23:52 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * manual/summary.awk: Recognize @defmumblex. * manual/signal.texi (Miscellaneous Signals): Use @deftypevrx for second description header. 1997-04-27 23:29 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * manual/arith.texi (Floating-Point Classes): Don't indent text, makeinfo doesn't like that. 1997-04-27 20:52 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * malloc/obstack.h (obstack_specify_allocation_with_arg, obstack_chunkfun, obstack_freefun): Fix casts. 1997-04-27 18:21 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * manual/xtract-typefun.awk: Allow names with only one character. 1997-04-26 14:16 Ulrich Drepper <drepper@cygnus.com> * sysdeps/unix/sysv/linux/netinet/ip_fw.h: Use <netinet/ip_icmp.h> not <netinet/icmp.h>.
