1997-06-15 00:43 Ulrich Drepper <drepper@cygnus.com> * Makeconfig: Define libc-map here. * Makefile: And remove definition here. * Makerules (load-map-file): Handle case where map file is in other directory. (build-shlib): Likewise. * libc.map: Add more symbols. * resolv/libresolv.map: Likewise. * db/libdb.map: Add __dbopen. Patch by HJ Lu. * libio/stdio.h: Remove "optmizations" for vfscanf and vsscanf. * locale/programs/localedef.c: Add normalize_codeset function. We don't want to use the _nl_normalize_codeset functions from libc. * sysdeps/libm-i387/s_asinh.S: Handle +-Inf and NaN correctly. * sysdeps/libm-i387/s_asinhf.S: Likewise. * sysdeps/libm-i387/s_asinhl.S: Likewise. * sysdeps/libm-i387/s_nearbyint.S: Correctly leave function. * sysdeps/libm-i387/s_nearbyintf.S: Likewise. * sysdeps/libm-i387/s_nearbyintl.S: Likewise. 1997-06-14 12:45 Thorsten Kukuk <kukuk@vt.uni-paderborn.de> * nis/nss_nis/nis-ethers.c: Add static to internal_nis_setetherent. * nis/nss_nis/nis-proto.c: Add static to internal_nis_setprotoent. * nis/nss_nisplus/nisplus-hosts.c: Rewrite parser and fix _nss_nisplus_gethostbyaddr_r interface. * nis/libnsl.map: Add all GLOBAL functions. 1997-06-13 18:32 Andreas Jaeger <aj@arthur.rhein-neckar.de> * libm-test.c (main): Call new tests, reorder tests. (fmod_test): Test function fmod. (nearbyint_test): Test function nearbyint. (acos_test): Add more test cases. (signbit_test): Test macro signbit. (output_result_bool): Output result if test fails. (asin_test): Add another test case. (atan2_test): Add more tests. (asinh_test): Add more tests. (atanh_test): Add more tests. (hypot_test): Add more tests. (isfinite_test): Test macro isfinite. (isnormal_test): Test macro isnormal. (sincos_test): Tests for sincos. (main): Enable remquo_test since the tests are correct (according to ANSI/IEEE 754-1985). (remquo_test): Corrected tests cases and added more tests. (remainder_test): Tests for remainder. (check_int): New Function to compare int values. (check_isnan_exc_ext): New function. (sqrt_test): Add some extra tests for sqrt. (erf_test): Tests for erf. (erfc_test): Tests for erfc. (gamma_test): Tests for gamma. (lgamma_test): Tests for lgamma. 1997-06-08 10:54 H.J. Lu <hjl@gnu.ai.mit.edu> * sysdeps/unix/sysv/linux/configure.in: Try to generate stdio_lim.h using the target C preprocessor and mk-stdiolim.c. * sysdeps/unix/sysv/linux/stdio_lim.h.in: New, template for stdio_lim.h. * sysdeps/unix/sysv/linux/mk-stdiolim.c: New, used by the target C preprocessor to extract OPEN_MAX and PATH_MAX. 1997-06-14 17:32 Andreas Jaeger <aj@arthur.rhein-neckar.de> * math/libm.map: Add inline functions, global variables.
