[Qemu-devel] [RISU RFC PATCH v2 00/14] Support for generating x86 MMX/SS

From: Jan Bobek
Subject: [Qemu-devel] [RISU RFC PATCH v2 00/14] Support for generating x86 MMX/SSE/AVX test images
Date: Mon, 1 Jul 2019 00:35:22 -0400

This is a v2 of the patch series first posted in [1]. This version also
implements the VEX prefix, hence all SIMD extensions up to AVX2 are
supported. Notable exceptions are LDMXCSR (cannot constrain memory
contents yet) and all forms of VGATHER (VSIB not implemented).

Note that this is still not the final version; I am planning to
implement randomization of VSIB to test VGATHER, and improve the way
registers are randomized (as discussed in e.g. [2]).

Changes since v1:
  - risugen_common: rewrote insnv to make it clearer, added a comment
    to randint_constr;
  - risugen_x86_asm: fixed a typo in rex_encode;
  - risugen_x86: use more than one opcode in write_mov_reg_imm to
    optimize space usage;
  - x86.risu: added all SIMD extensnions up to AVX2.
