This is the third part of vector instruction support for s390x. It is based
on part 2, which is will send a pull-request for to Conny soon.
Part 1: Vector Support Instructions
Part 2: Vector Integer Instructions
Part 3: Vector String Instructions
Part 4: Vector Floating-Point Instructions
The current state can be found at (kept updated):
https://github.com/davidhildenbrand/qemu/tree/vx
With the current state I can boot Linux kernel + user space compiled with
SIMD support. This allows to boot distributions compiled exclusively for
z13, requiring SIMD support. Also, it is now possible to build a complete
kernel using rpmbuild as quite some issues have been sorted out.
In this part, all Vector String Instructions introduced with the
"Vector Facility" are added.
v1 -> v2:
- Use the fancy bit-tricks from Richard to rewrite most string instructions
- Create specialized variants for "VECTOR STRING RANGE COMPARE", so the
compiler can optimize out the rt/!rt handling code.
