From: Joseph Myers Date: Mon, 14 Sep 2015 22:40:05 +0000 (+0000) Subject: Fix i386 exp missing underflows (bug 18961). X-Git-Tag: glibc-2.23~491 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=de5e81691c80468ff97c5260b4020aeaecfe418d;p=thirdparty%2Fglibc.git Fix i386 exp missing underflows (bug 18961). On i386, the double version of exp can miss underflow exceptions if the result is in the subnormal range for double but the last 11 bits of the 64-bit extended-precision mantissa happen to be zero. This patch forces the exception in a similar way to previous fixes. As with the exp2 fixes, the expf changes may in fact not be needed to ensure underflow exceptions, but are included for consistency and to fix the exp part of bug 18875 by ensuring that excess range and precision is removed from underflowing return values. Tested for x86_64 and x86. [BZ #18875] [BZ #18961] * sysdeps/i386/fpu/e_exp.S (dbl_min): New object. (MO): New macro.
