Does eglibc's own libm testsuite pass on your platform? I wonder if
oe-core is accidentally building eglibc without "big" libm for yo

I expect the standard response from upstream here would be that
floating point mathematics isn't exact and if you want exact answers

Hello,
I just want to point out that this looks very similar to a qemuppc
machine bug we've seen before with libm and floor() call:
https://bugzilla.yoctoproject.org/show_bug.cgi?id=4854
It was fixed with:

Hi,
I face a problem with libm. With my Dora build the following assertion doesn't
hold:
sqrt( pow( sqrt( 2.0 ), 4.0 ) ) == 2.0
1) With my old OE-classic / glibc-2.9 / PowerPC-hf it holds.
2) With my Debian desktop PC / glibc-2.17 / amd64 it holds.
3) With my new OE-core Dora / eglibc-2.18 / Po
14 matches
