Bug ID: 366413
Summary: s390x: New z13 instructions not implemented
Product: valgrind
Version: 3.12 SVN
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: vex
Assignee: jsew...@acm.org
Reporter: ar...@linux.vnet.ibm.com
Valgrind currently lacks support for the new z/Architecture instructions
that were first implemented with z13. In particular:
- load and zero rightmost byte (LZRF, LZRG);
- load logical and zero rightmost byte (LLZRGF);
- load halfword high immediate on condition (LOCHHI);
- load halfword immediate on condition (LOCHI, LOCGHI);
- load high on condition (LOCFHR, LOCFH);
- store high on condition (STOCFH);
- perform pseudorandom number operation (PPNO), with the functions
PPNO-Query and PPNO-SHA-512-DRNG;
- all vector facility instructions described in chapters 21-24 of the
z/Architecture Principles of Operations, eleventh edition (March, 2015):
- vector facility support instructions (chapter 21);
- vector facility integer instructions (chapter 22);
- vector facility string instructions (chapter 23);
- vector facility floating point instructions. (chapter 24);
- load count to block boundary (LCBB).
Supporting the new vector facility instructions requires modelling the new
z/Architecture vector registers.
Reproducible: Always
