Hi,
This is a fix for a pretty serious regression in GCC 4.7 onwards where
GCC is likely to put out wrong alignment specifiers in case of the neon
intrinsics. These specifiers appear to be much larger than the alignment
specifiers allowed by the architecture for the memory sizes allowed by
the
Hello
The attached patch fixes a race condition in __cxa_guard_acquire, a regression
from 4.6. When the code was refactored to use the new atomic intrinsics, the
fact that __atomic_compare_exchange_n updates the expected variable with the
current value was missed.
That causes the loop to
Hello
I detected this issue as I was updating the patches to send to the mailing
list. I have not created a bug report.
When the CAS operation fails and expected == guard_bit, __cxa_guard_acquire
will return immediately indicating that the initialisation has already
succeeded. However, it's
Hello
The attached patch is a simple improvement to make a thread that failed to set
the waiting bit to exit the function earlier, if it detects that another
thread has successfully finished initialising. It matches the CAS code from a
few lines above.
The change from RELAXED to ACQUIRE is

Hi,
this is a new version of the patch which makes ipa analysis produce

simplest diamond and semi-diamond CFG subgraphs. This time I also

CFG edges, which means I
