Hi Uros,
With your new fix that add if-then-else splitting for memory operand I
got expected performance speed-up - +6.7% for Atom and +8.4% for SNB.
We need to do all testing this weekend and I will get you our final
feedback on Monday.
Thanks ahead for all your help.
Yuri.

Honza left an ICE when we cannot compute number_of_iterations_exit

Hi,
below are two variants for PR 55355, one for trunk and for 4.7, the
second one, without dumping, for 4.6. On 4.6 they fix an ICE for a

I've changed the s390_extzv_shift_ok function and have added extzv

Hi all,
here is another attempt to make gfortran support user-requested backtraces.
A patch in this direction was already proposed by FX in March, but did
not make it in so far. It was last discussed in June, cf.

My understanding of shifts of constants in Go has improved. This patch
more accurately reflects the language spec when it comes to reporting
errors for invalid shifts. Bootstrapped and ran Go testsuite on
x86_64-unknown-linux-gnu. Committed to mainline.

In this bug, when we see the invalid initializer we changed the type of
x to be error_mark_node. But we had already built an ARRAY_REF to it
using the incomplete type. Then the back end gets confused by this
invalid expression wrapped in a valid one.
Fixed by not messing with the type of x.

Hi Rong,

This would allow optimizations like mapping the hot code alone to huge

This is useful to help understand and tune how the compiler will use

Yes, I didn't take enhancements in google branches into account while
