[PATCH v4 0/2] sim: riscv: Compressed instruction simulation

[<jaydeep.patil@imgtec.com>]

From: Jaydeep Patil <jaydeep.patil@imgtec.com>

Hi Mike, Andrew,

Addressed review comments.
 - Fixed riscv opcodes for NULL match_func
 - Added models for C extension
 - Using RA and SP from sim_riscv_regnum

I have removed the support for semi-hosting from this patch series, will push it
later once the spec is clear.

Jaydeep Patil (2):
  [sim/riscv] Fix crash during instruction decoding
  [sim/riscv] Add support for compressed integer instructions
