This patchset tries to fix some problem in current implementation for pointer
mask, and add support for pointer mask of instruction fetch.
The port is available here:
https://github.com/plctlab/plct-qemu/tree/plct-pm-fix-v2
v2:
* drop some error patchs
* Add patch 2 and 3 to fix the new problems
* Add patch 4 and 5 to use PC-relative translation for pointer mask for
instruction fetch
v3:
* use target_pc temp instead of cpu_pc to store into badaddr in patch 3
* use dest_gpr instead of tcg_temp_new() for succ_pc in patch 4
* enable CF_PCREL for system mode in seperate patch 5
Weiwei Li (6):
target/riscv: Fix pointer mask transformation for vector address
target/riscv: Update cur_pmmask/base when xl changes
target/riscv: Fix target address to update badaddr
target/riscv: Add support for PC-relative translation
target/riscv: Enable PC-relative translation in system mode
target/riscv: Add pointer mask support for instruction fetch
