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
