Hello Daniel, thanks for the patch. On 06/11/14 16:36, Daniel Hellstrom wrote: > Recent support for mcpu=leon3v7 and muser-mode were added > to GCC.

I compiled the RTEMS testsuite with this compiler and run it on an NGMP board. The results are all right.

Fine with me. Does spatc-elf need a refresh on its multilibs? --joel
Hi, Thanks for review and testing! Then I will apply it. Thanks for bringing up the sparc-elf. I think we would want the LEON3 in the t-elf, however I have to verify the LEON newlib C state and mflat etc. before activating that.
