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-v7
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
v4:
* Fix wrong pc_save value for conditional jump in patch 4
* Fix tcg_cflags overwrite problem to make CF_PCREL really work in new patch 5
* Fix tb mis-matched problem in new patch 6
v5:
* use gen_get_target_pc to compute target address of auipc and successor
address of jalr in patch 4.
* separate tcg related fix patches(5, 6) from this patchset
v6:
* rename gen_get_target_pc as g in patch 3 and patch 4
* use gen_pc_plus_diff to compute successor address of jal in patch 4
* mov comments for patch 5 to patch 4
v7:
* separate support for PC-relative translation and pointer mask for instruction
fetch (patch 3~6) out of this patchset
