I'm going to re-issue the outstanding 'future' patches as separate threads
under this message.
Compared to the original V4 patches, I have tried to break the larger patches
(particularly #4) into smaller chunks.
One of the V4 patches that I submitted was wrong, and this series of patches
corrects the issue (the issue was I used PC-relative offsets to add to a
register, and the current instruction definition does not support that). The
code modified dealt with vector extracts where the vector has a PC-relative
address, but the insn I added also broke normal switch statements.
This series of patches only adds one new constraint (em) that matches any
memory operand that does not use prefixed addressing (including PC-relative
addressing). In some of the previous V4 patches, I added two constraints.
I adjusted the code to address several of the previous comments:
* Eliminate having a TARGET_<xxx> test before calling a function that does
the same test;
* Fixing vector moves instruction length.
There are currently 15 patches in this set (as of this writing).
* Patches 1-10 provide the necessary functionality;
* Patch 11 sets the default for Linux 64-bit to use PC-relative and prefixed
instructions.
* Patches 12-14 are the tests to the test suite.
* Patch 15 is a patch to change how @pcrel is emitted to prevent some mixups
(like I had).
I had originally posted a patch to support PCREL_OPT in the V3 series. Given
your comments, I plan to re-implement it, so it is not part of this patch set.
