[Qemu-devel] [PATCH 00/15] target/xtensa: preparation for FLIX support

[Max Filippov <jcmvbkbc@gmail.com>]

Hello,

this series prepares target/xtensa for FLIX (flexible length instruction
extensions) support. FLIX allows bundling multiple existing opcodes in a
single instruction, so this series separates generation of per-instruction
code (such as raising exceptions and terminating TB) from per-opcode code.

Max Filippov (15):
  target/xtensa: extract test for an illegal instruction
  target/xtensa: extract test for privileged instruction
  target/xtensa: extract test for syscall instruction
  target/xtensa: extract test for debug exception
  target/xtensa: extract test for window overflow exception
  target/xtensa: extract test for window underflow exception
  target/xtensa: extract test for alloca exception
  target/xtensa: extract test for cpdisabled exception
  target/xtensa: extract test for division by zero
  target/xtensa: extract unconditional TB termination
  target/xtensa: change SR number checks to assertions
  target/xtensa: always end TB on CCOUNT access/CCOMPARE write
  target/xtensa: extract unconditional TB termination via slot 0
  target/xtensa: make rsr/wsr helpers return void
  target/xtensa: extract gen_check_interrupts call
