[Qemu-devel] [PATCH v2 00/68] target/arm: Convert aa32 base isa to decodetree
Posted by Richard Henderson 4 years, 8 months ago
This unifies the implementation of the actual instructions for
a32, t32, and t16.

This has been tested by running the debian 9 armhf installer,
which does a far amount of switching between arm and thumb modes.
I've also run Peter's ARM TFM image, and all of the existing
RISU tests that we have.  (Our RISU test cases are nowhere near
complete for 32-bit mode, but it did find 3 bugs, so not useless.)

Based-on: 20190819151743.17267-1-richard.henderson@linaro.org
"[PULL 0/3] decodetree improvements"

Changes from v1:
  * Lots of prep patches merged.
  * Lots of patches split into smaller bits.
    Which is why this patch set is larger than v1 despite the merge.
  * Do not use STREG_EXC_RET in Hyp mode (patch 3).
  * Map more UNPREDICTABLE to UNDEF in LDM/STM (patches 28-30).
  * Split gen_nop_hint (patch 59).
  * Do not move single-step check to gen_goto_tb, but do simplify
    gen_jmp by inlining gen_bx_im (patch 68).
