The code generated by -mcmodel=medany is defined to be
position-independent, but is not guarnteed to function correctly when
linked into position-independent executables or libraries. See the
recent discussion at the psABI specification [1] for more details.
[1]: https://github.com/riscv-non-isa/
Restrict negative offset computation only to dynamic object sizes, where
size expressions are accurate and not a maximum/minimum estimate and in
cases where negative offsets definitely mean an underflow, e.g. in
MEM_REF of the whole object with negative ofset in addr_object_size.

The cprop_hardreg pass is built around the assumption that accessing a
register in a narrower mode is the same as accessing the lowpart of
the register. This unfortunately is not true for vector registers on
IBM Z. This caused a miscompile of LLVM with GCC 8.5. The problem
could not be reproduced

At some point during the development of this patch series, it appeared

These tests are derived from the one provided in the PR: there is a
compile-only test because I did not have access to anything that could

Variable indexing of a __builtin_shufflevector result is broken because
we fail to properly mark the TARGET_EXPR decl as addressable.
Bootstrapped and tested on x86_64-unknown-linux-gnu, OK?

A quick addition to range ops for
LHS = OP1 >> OP2
if OP1 and OP2 are both >= 0, then we can register the relation LHS
<= OP1 and all the expected good things happen.
Bootstrapped on x86_64-pc-linux-gnu with no regressions.
OK for trunk?

Better
for (gfc_omp_namelist *n = *head; n; n = n->next)
as we are in C++ and n isn't used after the loop.

Updated patch: this version fixes some missed cases of malloc in the
