Date: Wed, 13 Dec 2017 10:04:00 -0000 [thread overview] Message-ID: <20171213100415.68426.qmail@sourceware.org> (raw) https://sourceware.org/git/gitweb.cgi?p=newlib-cygwin.git;h=c338bc22554fcddf64f12148785d07c1a4021160 commit c338bc22554fcddf64f12148785d07c1a4021160 Author: Jim Wilson <jimw@sifive.com> Date: Tue Dec 12 11:38:01 2017 -0800 Don't call double rint from float powf. Updated patch to use 0.0f in addition to calling rintf. Tested same way as before, with a testcase that triggers the code and make check. OK? newlib/ * libm/math/wf_pow.c (powf): Call rintf instead of rint. Use 0.0f for compare.
