No more backports, but the S390 fix for trunk is still in the queue. After it
gets the bug can be resolved.

Fixed on aarch64 for 6.3 as well. There's nothing more to do for aarch64 here.
Dominik, do you intend to do any backports of the s390 patches? Or can we close
this?

I see.
This test verifies that a negative "pos" is indeed rejected:

int g;
void foo(int64_t b)
{
if (b >> 65 & 1)
g = b;
}

Regarding the ARM patch:
+ {
+if (!IN_RANGE (INTVAL (operands[2]) + INTVAL (operands[3]),
+ 1, GET_MODE_BITSIZE (DImode) - 1))
+ FAIL;

Isn't this patch too simple? On s390x

Ah, so combine isn't really doing anything wrong here -- for the "plain"
shift it already only refuses it because the target does not allow it.
Some targets *do* allow shifting by amounts more than a

OK, to avoid the .gch includes, build with PRECOMPILE=0 REGENIE=1. I'm
attaching the result.

--- Comment #9 from Andrew Pinski ---
do the following to remove the PCH:
rm -rF ./obj/Release/emu.h.gch
and then rebuild the preprocessed source.
