Bug #: 52496
Summary: avr-specific built-ins missing memory barrier
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: gjl@gcc.gnu.org
Target: avr
avr-specific built-in functions like
__builtin_avr_sei
__builtin_avr_cli
__builtin_avr_wdr
__builtin_avr_sleep
__builtin_avr_delay_cycles
are missing memory barriers to avoid reordering against memory accesses.
