1997-04-15 03:14 Ulrich Drepper <drepper@cygnus.com> * wcsmbs/wcsstr.c: Add weak alias wcswcs for Unix98 compliance. * math/Makefile (libm-calls): Add s_sincos and s_cproj. * math/mathcalls.h: Add prototype for sincos. * sysdeps/i386/fpu/__math.h: Warn about restriction on arguments to inlined sin and cos function. Define functions new in ISO C 9X when __USE_ISOC9X is defined. Add optimized version of finite. Rewrite sincos function to handle too large arguments. * sysdeps/libm-i387/s_cos.S: Better code alignment. * sysdeps/libm-i387/s_cosl.S: Likewise. * sysdeps/libm-i387/s_sin.S: Likewise. * sysdeps/libm-i387/s_sinl.S: Likewise. * sysdeps/libm-i387/s_finite.S: Yet better code. * sysdeps/libm-i387/s_finitef.S: Likewise. * sysdeps/libm-i387/s_sincos.S: New file. * sysdeps/libm-i387/s_sincosf.S: New file. * sysdeps/libm-i387/s_sincosl.S: New file. * sysdeps/libm-ieee754/s_sincos.c: New file. * sysdeps/libm-ieee754/s_sincosf.c: New file. * sysdeps/libm-ieee754/s_sincosl.c: New file. * sysdeps/libm-ieee754/s_ccosh.c: Change to use sincos function. * 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_ctan.c: Likewise. * sysdeps/libm-ieee754/s_ctanf.c: Likewise. * sysdeps/libm-ieee754/s_ctanl.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_cosl.c: Correct check for range. * sysdeps/libm-ieee754/s_sinl.c: Likewise. * sysdeps/libm-ieee754/s_roundtol.c: Fix typos. * sysdeps/libm-ieee754/s_roundtoll.c: Likewise. * nis/Makefile (services): Mention nisplus before compat. * nis/nis_call.c (__do_niscall): Change type of variable server_len to prevent warning. * nis/nss_compat/compat-grp.c (getgrent_next_file_plusgroup): Add cast to prevent warning. * nis/nss_compat/compat-pwd.c (getpwent_next_file_plususer): Likewise. * nis/nss_compat/compat-spwd.c (getspent_next_file_plususer): Likewise. * nis/nss_nisplus/nisplus-hosts.c (_nss_nisplus_parse_hostent): Change type of variable `i' to prevent warning. * nis/nss_nisplus/nisplus-network.c (_nss_nisplus_parse_netent): Likewise. * nis/nss_nisplus/nisplus-proto.c (_nss_nisplus_parse_protoent): Likewise. * nis/nss_nisplus/nisplus-rpc.c (_nss_nisplus_parse_rpcent): Likewise. * nis/nss_nisplus/nisplus-service.c (_nss_nisplus_parse_servent): Likewise. * sysdeps/generic/Dist: Remove old math implementation files. * sysdeps/generic/mathimpl.h: Removed. * sysdeps/generic/trig.h: Removed. * sysdeps/generic/sincos.c: Removed. * sysdeps/generic/asincos.c: Removed. * sysdeps/generic/exp__E.c: Removed. * sysdeps/generic/log__L.c: Removed. 1997-04-13 17:18 Wolfram Gloger <wmglo@dent.med.uni-muenchen.de> * malloc/malloc.c (fREe): Small optimization. Before returning, add fast check whether the heap containing top can go away. 1997-04-11 16:46 Wolfram Gloger <wmglo@dent.med.uni-muenchen.de> * malloc/malloc.c (mALLOc, rEALLOc, cALLOc, mEMALIGn): When failing to allocate a new chunk, also try the main_arena. It may be that we are only running out of mmapped regions, and other arenas cannot be enlarged sufficiently. (new_heap, malloc_extend_top): Handle top_pad more consistently, i.e. only in new_heap(). 1997-04-13 21:10 Philip Blundell <pjb27@cl.cam.ac.uk> * sysdeps/posix/Makefile: Don't try to build and run mk-stdiolim if cross-compiling. * configure.in: Recognise "...linuxaout" OS names and turn off ELF. * configure.in: Add ARM support. * sysdeps/arm/Implies: New file. * sysdeps/arm/__longjmp.S: New file. * sysdeps/arm/bsd-_setjmp: New file. * sysdeps/arm/bsd-setjmp: New file. * sysdeps/arm/bytesex.h: New file. * sysdeps/arm/fpu_control.h: New file. * sysdeps/arm/jmp_buf.h: New file. * sysdeps/arm/setjmp.h: New file. * sysdeps/arm/sysdep.h: New file. * sysdeps/unix/arm/config.h: New file. 1997-04-14 04:03 Ulrich Drepper <drepper@cygnus.com> * sysdeps/libm-ieee754/s_cproj.c: New file. * sysdeps/libm-ieee754/s_cprojf.c: New file. * sysdeps/libm-ieee754/s_cprojl.c: New file.
