We use a negative ID number to link together the doloop_begin and
doloop_end instructions. This negative ID number is setup within
doloop_begin, at this point the ID is stored into the loop end
instruction (doloop_end_i) and placed into the doloop_begin_i
instruction.
In arc.c (arc_reorg) we extract the ID from the doloop_end_i
instruction in order to find the matching doloop_begin_i instruction,
though the ID is only used in some cases.
Currently in arc_reorg when we extract the ID we negate it. This
negation is invalid. The ID stored in both doloop_end_i and
doloop_begin_i is already negative, the negation in arc_reorg means
that if we need to use the ID to find the doloop_begin_i then we will
never find it (as the IDs will never match).
This commit removes the unneeded negation, moves the extraction of the
ID into a more appropriately scoped block and adds a new test for this
issue.
gcc/ChangeLog:
* config/arc/arc.c (arc_reorg): Move loop_end_id into a more local
block, and do not negate it, the stored id is already negative.

* gcc.target/arc/loop-1.c: New file.

The old ARC assembler would accept expressions like 'LABEL-(.&-4)'
which would calculate the offset from the PCL to LABEL. The new ARC
assembler does not accept these expressions, instead there's an @pcl
synax, used like LABEL@pcl which gives the offset from PCL to LABEL.
Most of the use of the old expression syntax have been removed,
however, this one got missed.
gcc/ChangeLog:
* config/arc/arc.md (doloop_begin_i): Use @pcl assembler syntax.
