Seemingly, the patch which caused this made it now to GCC 10;
at least it fails now with offloading on the OG10 branch, after
merging the trunk into that branch.
Hence, I committed this to GCC 10 to avoid this ICE. It occurs
here for libgomp.c/../libgomp.c-c++-common/reduction-16.c when

Hi,
Previously, the machine description patterns for vst1q accepted a generic memory
operand for the destination, which could lead to an unrecognised builtin when
expanding vst1q* intrinsics. This change fixes the pattern to only accept MVE
memory operands.

This patch improves the code generated on PA-RISC for DImode
(double word) left shifts by small constants (1-31). This target
has a very cool shd instruction that can be recognized by combine
for simple shifts, but relying on combine is fragile for more
complicated functions. This patch tweaks

this could be also something for the trunk, matching C/C++

These tests do not actually require TBB, because they only inspect the
feature test macros present in the headers. However, if TBB is installed
then its headers will be included, and the version will be checked. If

Hi Palmer,
The 64-bit RISC-V Linux port has a minimum of 39-bit virtual addresses, so it
should be 1<<36 for 64-bit targets. In the implementation of address sanitizer,
we need a shadow memory that is 1/8th of the memory size, which is
where the 36 comes from. I don't think the choice of this
