Bug ID: 60808 Summary: Typo in definition of ATxmega256A3BU Product: gcc Version: 4.9.0 Status: UNCONFIRMED Severity: critical Priority: P3 Component: target Assignee: unassigned at gcc dot gnu.org Reporter: vonzeng at ibr dot cs.tu-bs.de Created attachment 32579 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=32579&action=edit typo fix There is a typo in gcc/config/avr/avr-mcus.de. The mmcpu definition of the ATxmega256A3BU is __AVR_ATxmega258A3BU__. This leads to errors while compiling the avr-libc, this is way I marked the bug critical. Attached is the very easy patch to fix it.
