target-xtensa: implement disas_xtensa_insn Set up disas_xtensa_insn switch structure, mark required options on high level groups. Implement arithmetic/bit logic/jump/call0. Implement code generation loop with single step/breakpoint checking. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

target-xtensa: implement exceptions - mark privileged opcodes with ring check; - make debug exception on exception handler entry. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

target-xtensa: implement shifts (ST1 and RST1 groups) - ST1: SAR (shift amount special register) manipulation, NSA(U); - RST1: shifts, 16-bit multiplication. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

target-xtensa: implement windowed registers See ISA, 4.7.1 for details. Physical registers and currently visible window are separate fields in CPUEnv. Only current window is accessible to TCG. On operations that change window base helpers copy current window to and from physical registers. Window overflow check described in 4.7.1.3 is in separate patch.

target-xtensa: implement loop option See ISA, 4.3.2 for details. Operations that change LEND SR value invalidate TBs at the old and at the new LEND. LEND value at TB compilation time is considered constant and loop instruction is generated based on this value. Invalidation may be avoided for the TB at the old LEND address, since looping code verifies actual LEND value. Invalidation may be avoided for the TB at the new LEND address if there's a way to associate LEND address with TB at compilation time and later verify that it doesn't change.

target-xtensa: implement SIMCALL Tensilica iss provides support for applications running in freestanding environment through SIMCALL command. It is used by Tensilica libc to access argc/argv, for file I/O, etc. Note that simcalls that accept buffer addresses expect virtual addresses.
