[PATCH v3 0/3] sim: riscv: Compressed instruction simulation and semi-hosting support

[<jaydeep.patil@imgtec.com>]

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

Hi Andrew,

Addressed review comments.

The compressed instructions can be tested without the need for GDB test
and semi-hosting support. Simulator specific tests are added in
sim/testsuite/riscv/c-ext.s file.

I have now combined the semi-hosting support in one patch (v3-0003-*). This is
based on semi-hosting calls generated by newlib (--specs=semihost.specs option)
and picolibc libraries.

  [sim/riscv] Fix crash during instruction decoding
  [sim/riscv] Add support for compressed integer instruction set simulation
  [sim/riscv] Add semi-hosting support
