Hi,
Currently GCC is happy to use LDRD to perform a 64bit load on ARMv7-R,
as shown by the testcase on this patch. However, LDRD is only atomic
when LPAE extensions is available, which they are not for ARMv7-R. This
commit solve the issue by introducing a new feature bit to distinguish
LPAE extensions instead of deducing it from div instruction
availability.
Ok but with the testsuite fix that I just approved, please also fix
in gcc-5 branch.
The backport already contains it. I haven't asked for gcc-5 branch yet because
testing is still ongoing. Will send a separate mail once testing is done.
Best regards,
Thomas
