I've confirmed that -mhard-float compiles and boots core-image-minimal with no floating point related issue. I've also compiled a program generating a floating point instruction and run it on the core I have in front of me (mpc8314e) The e300c2 does not have an fpu. Maybe it is just a copy and past error. 34515 1 dvhart 2013-07-11 13:59:20 +0000 When you say copy and paste error - where? Which document/file? What are you looking for as a resolution here? For a new machine definition with a tune file using -mhard-float? My ppc hardware is broken currently. Perhaps you would care to provide a patch and test results? 34523 2 1324 myopiate 2013-07-11 22:52:22 +0000 Created attachment 1324 proposed patch 34524 3 myopiate 2013-07-11 23:04:56 +0000 (In reply to comment #1) I apologize that my report wasn't detailed enough. > When you say copy and paste error - where? Which document/file? meta/conf/machine/include/tune-ppce300c2.inc . As I explained, the e300c2 core does not have an fpu, the e300c3 does. http://www.freescale.com/files/32bit/doc/ref_manual/e300coreRM.pdf > What are you looking for as a resolution here?

Patch proposed. 45848 4 bluelightning 2014-09-25 15:15:52 +0000 This seems to have slipped through the cracks. Kevin is this something you could check into? 45914 5 kexin.hao 2014-09-28 05:47:48 +0000 This issue has been fixed in 1.7 by the following commit: commit 3e528d3e4bc542ca2f654c54363c56af0fb9f61b Author: Mats Kärrman <Mats.Karrman@tritech.se> Date: Tue Apr 1 16:20:34 2014 +0000 Make ppce300c3 tune hard-float by default The tuning file for PowerPC e300c3 is soft-float. In OE-classic it was hard- float and it should be as the c3 has an fpu. I have modified the tuning file to include both a hard-float version (using the existing ppce300c3 name) and an optional soft-float version (called ppce300c3-nf). The following patch also passes a "--with-cpu=e300c3" argument to GLIBC. For this to have any effect the sqrt/sqrtf implementations added by the "glibc.fix_sqrt2.patch" are required and also an additional "Implies" file (added to the mentioned patch as a separate patch for eglibc_2.19). Tested with eglibc 2.19 on PowerPC MPC5125.
