From 105f2ed368ed61785a0a63ddb47fc62b89b58e0d Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Thu, 28 Mar 2019 19:14:04 +0000 Subject: math: Use wordsize-64 version for s_logb - The resulting binary difference on 32 bits architecture is minimum. On i686-linux-gnu (with architecture optimization routine removed) there is no different using logb benchtests - It helps wordsize-64 architectures that use ldbl-opt. - It add some code simplification with reduction of duplicated implementations. Checked on powerpc-linux-gnu (built without --with-cpu, with --with-cpu=power4 and with --with-cpu=power5+ and --disable-multi-arch), powerpc64-linux-gnu (built without --with-cp and with --with-cpu=power5+ and --disable-multi-arch). * sysdeps/ieee754/dbl-64/wordsize-64/s_logb.c: Move to ... * sysdeps/ieee754/dbl-64/s_logb.c: ... here. Add work around for powerpc32 integer 0 converting to -0. Reviewed-by: Gabriel F. T.
