Hi,
this patch fixes BUILT_IN_UNREACHABLE declaration of C frontned. The function
is also pure (so DSE can do its job). As a special case ECF flags for
CONST NORETURN also add looping, so this declaration is correct.
The implicit declaration of the builtin is already set this way.

Hi,
Quite a few tests fail for big-endian multilibs which use VFP
instructions at present. One reason for many of these is glaringly
obvious once you notice it: for D registers interpreted as two S
registers, the lower-numbered register is always the less-significant
part of the value, and the

Hi,
this patch fixes heuristic on decide_unroll_constant_iterations to take into
account the profile: even when the loop is known to have constant loop
iteration bound, it doesn't need to really iterate many times. So use profile
and loop_max to double check that this is the case.

The patch was fully tested on x86_64-suse-linux, where it removes half of
the useless stores in the original testcase for PR rtl-optimization/54315,
and manually tested for arm-linux-gnueabi (for now), where it also removes
stores for small structures. Comments?
