1997-03-27 02:28 Ulrich Drepper <drepper@cygnus.com> * gmon/gmon.c (monstartup): Mark all messages. (write_call_graph): Rewrite to use larger I/O vector for writev call to reduce syscall overhead. (write_bb_counts): Simplify writev handling. * inet/rexec.c: Make string parameters `const'. * resolv/netdb.h: Add prototypes for rcmd, rexec, ruserok, and rresvport. * math/Makefile: Don't define CFLAGS-* macros to prevent inlining in libm-test. * math/libm-test.c (this_does_nothing): Remove functions. It's notuseful on any platform but ix86. (inverse_func_pair_test): Don't use this_does_nothing. Use memory reference. (identities1_test): Likewise. (identities2_test): Likewise. (identities3_test): Likewise. (basic_test): Likewise. Patch by Andreas Schwab. (BUILD_COMPLEX): New macro. Create complex number from real and imaginary parts. This works around bugs/inefficiencies in current gcc. (cexp_test): Use BUILD_COMPLEX. Add more tests. * nss/nsswitch.c: Fix typo. * posix/glob.h: Add declaration for glob_pattern_p. * posix/glob.c: Rename glob_pattern_p to __glob_pattern_p and make glob_pattern_p a weak alias. This function is used in other packages (e.g. bash). * signal/Makefile (routines): Add sigisempty, sigandset, and sigorset. * signal/signal.h: Add prototypes for sigisempty, sigandset, and sigorset. * signal/sigisempty.c: New file. * signal/sigandset.c: New file. * signal/sigorset.c: New file. * sysdeps/generic/sigset.h: Define __sigisemptyset, __sigandset, and __sigorset. * sysdeps/unix/sysv/linux/sigset.h: Likewise. * stdlib/strtod.c: Handle `n-char-sequence' in NaN parsing. It determines the bits in the mantissa part of the NaN. * stdlib/strtof.c: Define SET_MANTISSA for float type. * wcsmbs/wcstof.c: Define SET_MANTISSA for float type. * stdlib/strtold.c: Define SET_MANTISSA for long double type. * wcsmbs/wcstold.c: Define SET_MANTISSA for long double type. * sysdeps/libm-ieee754/s_cexp.c: Use explicit assignment to complex number components. Some more corrects for special cases. * sysdeps/libm-ieee754/s_cexpf.c: Likewise. * sysdeps/libm-ieee754/s_cexpl.c: Likewise. * sysdeps/sparc/elf/start.S: Remove as per request of Miguel de Icaza. * sysdeps/unix/sysv/linux/netinet/icmp.h: Remove since we have ip_icmp.h. Reported by HJ Lu. 1997-03-25 03:50 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * sysdeps/m68k/Makefile (CFLAGS-rtld.c): Add -Wno-unused. * sysdeps/m68k/dl-machine.h (elf_machine_rela): Rewritten as for i386. (elf_machine_lookup_noexec_p, elf_machine_lookup_noplt_p, ELF_MACHINE_RELOC_NOPLT): Define. 1997-03-25 03:48 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * grp/grp.h: Include <stddef.h> only once. 1997-03-25 09:38 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * sysdeps/unix/sysv/linux/termbits.h (OXTABS): Don't define. * sysdeps/unix/sysv/linux/alpha/termbits.h (OXTABS): Likewise. * termios/sys/ttydefaults.h (TTYDEF_OFLAG): Use either OXTABS or TAB3, if one of them is defined. 1997-03-26 04:53 Ulrich Drepper <drepper@cygnus.com> * posix/glob.c (next_brace_sub): Decrement depth counter when '}' is found. Patch by Dennis Henriksen <opus@flamingo.osrl.dk>. 1997-03-25 16:25 Thorsten Kukuk <kukuk@vt.uni-paderborn.de> * sunrpc/Makefile: Comment gccwarn out. * sunrpc/auth_none.c: Fix prototypes and parameters for compiling with enabled warnings. * sunrpc/auth_unix.c: Likewise. * sunrpc/authuxprot.c: Likewise. * sunrpc/bindrsvprt.c: Likewise. * sunrpc/clnt_gen.c: Likewise. * sunrpc/clnt_perr.c: Likewise. * sunrpc/clnt_raw.c: Likewise. * sunrpc/clnt_simp.c: Likewise. * sunrpc/clnt_tcp.c: Likewise. * sunrpc/clnt_udp.c: Likewise. * sunrpc/get_myaddr.c: Likewise. * sunrpc/getrpcport.c: Likewise. * sunrpc/pm_getmaps.c: Likewise. * sunrpc/pm_getport.c: Likewise. * sunrpc/pmap_clnt.c: Likewise. * sunrpc/pmap_prot.c: Likewise. * sunrpc/pmap_prot2.c: Likewise. * sunrpc/pmap_rmt.c: Likewise. * sunrpc/rpc/auth.h: Likewise. * sunrpc/rpc/clnt.h: Likewise. * sunrpc/rpc/pmap_clnt.h: Likewise. * sunrpc/rpc/svc.h: Likewise. * sunrpc/rpc/svc_auth.h: Likewise. * sunrpc/rpc/types.h: Likewise. * sunrpc/rpc/xdr.h: Likewise. * sunrpc/rpc_clntout.c: Likewise. * sunrpc/rpc_cmsg.c: Likewise. * sunrpc/rpc_dtable.c: Likewise. * sunrpc/rpc_prot.c: Likewise. * sunrpc/svc.c: Likewise. * sunrpc/svc_auth.c: Likewise. * sunrpc/svc_authux.c: Likewise. * sunrpc/svc_raw.c: Likewise. * sunrpc/svc_run.c: Likewise. * sunrpc/svc_simple.c: Likewise. * sunrpc/svc_tcp.c: Likewise. * sunrpc/svc_udp.c: Likewise. * sunrpc/xdr.c: Likewise. * sunrpc/xdr_array.c: Likewise. * sunrpc/xdr_mem.c: Likewise. * sunrpc/xdr_rec.c: Likewise. * sunrpc/xdr_ref.c: Likewise. * sunrpc/xdr_stdio.c: Likewise. 1997-03-25 13:39 Ulrich Drepper <drepper@cygnus.com> * math/libm-test.c (log2_test): Compile this function and call it. (exp2_test): Likewise, but check whether function really exists before testing. * math/Makefile (libm-calls): Add s_log2 and s_exp2. 1997-03-25 04:50 Ulrich Drepper <drepper@cygnus.com> Implement exp2 function. * sysdeps/libm-i387/s_exp2.S: New file. * sysdeps/libm-i387/s_exp2f.S: New file. * sysdeps/libm-i387/s_exp2l.S: New file.
