1997-03-20 01:49 Ulrich Drepper <drepper@cygnus.com> * sysdeps/libm-ieee754/s_tanhl.c (__tanhl): Correct handling of -inf. * Makeconfig: (rpath-link): Add math/ directory. (math-objdir): New variable. (link-extra-lib): Define to special version when $(common-objpfx)!=$(objpfx) to allow libraries outside $(common-objpfx) be linked to the application. * math/Makefile: Add rules to build and run test programs. * math/libm-test.c (_GNU_SOURCE): Define only if still undefined. (check_equal): Correct check for error. (ceil_test): Fix typo. (log_test): Fix typo. (floor_test): Fix typo. (pow_test): Fix typos. (log10_test): Allow slight incorrectness for `log10(e)'. (modf_test): New functions to test `modf' et.al. (hypot_test): Rewrite test completely. Patch partly by Andreas Jaeger. * math/test-double.h (__NO_MATH_INLINES): Define only if not already defined. * math/test-float.h: Likewise. * math/test-logdouble.h: Likewise. * setjmp/setjmp.h: Change references of ANSI C to ISO C. * setjmp/tst-setjmp.c: Correct and extend test suite. * sysdeps/i386/__longjmp.S: Update copyright. * sysdeps/i386/bsd-_setjmp.S: Correct fatal bug in jump to `__sigsetjmp' in PIC code. * sysdeps/i386/bsd-setjmp.S: Likewise. * sysdeps/libm-i387/e_pow.S: Correct recognition of mantissa overflow. * sysdeps/libm-i387/e_powf.S: Likewise. * sysdeps/libm-i387/s_expm1.S: Handle x == +-0 as a special case since expm1(-0) == -0. * sysdeps/libm-i387/s_expm1f.S: Likewise. * sysdeps/libm-i387/s_expm1l.S: Likewise. * sysdeps/libm-ieee754/s_modf.c: Optimize code by avoiding unneeded access to FP number. * sysdeps/libm-ieee754/s_modff.c: Likewise. * sysdeps/libm-ieee754/s_modfl.c: Correct former completely bogus code. It never worked correctly. * sysdeps/libm-ieee754/s_tanh.c: Handle x == +-0 as a special case since tanh(-0) == -0. * sysdeps/libm-ieee754/s_tanhf.c: Likewise. 1997-03-19 21:13 Ulrich Drepper <drepper@cygnus.com> * stdlib/strtod.c (STRTOL): Use wchar_t as type for `decimal' and `thousands' to support systems with sizeof(wchar_t) != sizeof(wint_t). Blargh. * sysdeps/unix/sysv/linux/socketbits.h: Remove definition of SOL_IP, SOL_TCP, SOL_UDP, and SOL_IPX as they are defined in appropriate headers. * sysdeps/unix/sysv/linux/writev.c: Don't use MAX_IOVEC. Test for UIO_FASTIOV and set to 8 if not available. * sysdeps/unix/sysv/linux/readv.c: Likewise. Patch by HJ Lu. * sysdeps/unix/sysv/linux/xstat.c: Include <kernel_stat.h>, not "kernel_stat.h". * sysdeps/unix/sysv/linux/lxstat.c: Likewise. * sysdeps/unix/sysv/linux/fxstat.c: Likewise. Reported by fabsoft@fabsoft2.zarm.uni-bremen.de.
