Hi all,

It looks like Zjpm v0.8 is almost frozen and we don't expect it change drastically anymore.
Compared to the original implementation with explicit base and mask CSRs, we now only have
several fixed options for number of masked bits which are set using existing CSRs.

Thanks

[previous:]

This series of patches intends to update RISC-V Pointer Masking implementation
to the latest Zjpm v0.6.1 version.
The Pointer Masking functionality is simplified compared to previous version
of spec.
The changes have been tested with handwritten assembly tests and LLVM HWASAN
test suite.

Thanks

Alexey Baturo (6):
  target/riscv: Remove obsolete pointer masking extension code.
  target/riscv: Add new CSR fields for S{sn,mn,m}pm extensions as part
    of Zjpm v0.8
  target/riscv: Add pointer masking tb flags
  target/riscv: Add functions to calculate current number of masked bits
    for pointer masking
  target/riscv: Update address modify functions to take into account
    pointer masking
  target/riscv: Enable updates for pointer masking variables and thus
    enable pointer masking extension
