Hi Andrew,

Addressed review comments. Simulator specific tests are added in sim/testsuite/riscv/c-ext.s file.

This is a collection of patches that add simulation of compressed integer instruction set ("c") and semi-hosting support to the RISC-V simulator. Two tests are added in gdb.arch to test basic semi-hosting and then the simulation of compressed integer instructions.

Patch #1 adds basic semi-hosting support (OPEN, EXIT and GET_CMDLINE) and gdb.arch/riscv-exit-getcmd.c test

Patch #2 adds support for compressed integer instruction set ("c") and gdb.arch/riscv-insn-simulation.c and sim/testsuite/riscv/c-ext.s tests

Patch #3 adds support for remaining semi-hosting calls
