This is the final part of vector instruction support for s390x.
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
It is based on:
- [PATCH v2 0/5] s390x/tcg: Vector Instruction Support Part 3
- [PATCH v1 0/2] s390x: Fix vector register alignment
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.
While the current state works fine for me with RHEL 8, I am experiencing
some issues with newer userspace versions. I already found and fixed
some stack overflow protection issues (stfle instruction). I still see
random rpm database corruptions and rpmbuild doesn't work correctly
(looks like another stack protection issue).
In this part, all Vector Floating-Point Instructions introduced with the
"Vector Facility" are added. Also, the "qemu" model is changed to a
z13 machine.
v1 -> v2:
- get rid of make_float64() and float64_val().
- fixed two cc calculation issues (thanks Richard)
- Rework "VECTOR FP COMPARE (EQUAL|HIGH|HIGH OR EQUAL)"
- Rework "VECTOR FP MULTIPLY AND (ADD|SUBTRACT)"
- Use gvec expansion in "s390x/tcg: Implement VECTOR FP PERFORM SIGN
OPERATION"
