* Fix exp2 spurious underflows (bug 16560).Joseph Myers2015-02-121-0/+9
| | | | | | | | | | | | | | | | | | | | | | This patch fixes the remaining part of bug 16560, spurious underflows from exp2 of arguments close to 0 (when the result is close to 1, so should not underflow), by just using 1+x instead of a more complicated calculation when the argument is sufficiently small. Tested for x86_64, x86 and mips64. [BZ #16560] * math/e_exp2l.c [LDBL_MANT_DIG == 106] (LDBL_EPSILON): Undefine and redefine. (__ieee754_exp2l): Do not multiply small fractional parts by M_LN2l. * sysdeps/i386/fpu/e_exp2l.S (__ieee754_exp2l): Just add 1 to small argument. * sysdeps/ieee754/dbl-64/e_exp2.c (__ieee754_exp2): Likewise. * sysdeps/ieee754/flt-32/e_exp2f.c (__ieee754_exp2f): Likewise. * sysdeps/x86_64/fpu/e_exp2l.S (__ieee754_exp2l): Likewise. * math/auto-libm-test-in: Add more tests of exp2. * math/auto-libm-test-out: Regenerated.

* Optimize libmUlrich Drepper2011-10-121-0/+1
| | | | | libm is now somewhat integrated with gcc's -ffinite-math-only option and lots of the wrapper functions have been optimized.

* * Makerules ($(+sysdir_pfx)sysd-rules): Emit pattern rules to installRoland McGrath2006-01-171-8/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | into $(inst_includedir)/%.h from sysdirs. [headers]: Change static pattern rule for installing $(headers) to do only those not matching %.h. ($(inst_includedir)/%.h: $(objpfx)%.h): Add this pattern rule instead. ($(inst_includedir)/%.h: %.h): Likewise. ($(inst_includedir)/%.h: $(..)include/%.h): Likewise. * Makefile ($(inst_includedir)/gnu/stubs.h): Add $(make-target-directory). * stdlib/Makefile (headers): Restore headers removed in last change. 2006-01-16 Jakub Jelinek <jakub@redhat.com> * math/e_exp2l.c: Don't include stdio.h, errno.h, stub-tag.h, include math_private.h. (__ieee754_exp2l): Compute for now as expl (M_LN2l * x) instead of failing. (exp2l): Remove stub_warning. 2006-01-15 Jakub Jelinek <jakub@redhat.com> * io/tst-faccessat.c (do_test): Don't fail if geteuid () == 0.
