-rw-r--r-- 1169 saferewrite-20211125/src/encode_761xfreeze3/README2021.09.03 tests with pip version of angr:

   * avx gives warning-unrollerror with clang -O1 and gcc -O3 since
     Iop_QNarrowBin16Sto8Sx16 isn't supported in angr.

   * ref gives warning-unrollerror with gcc -O3 since
     Iop_QNarrowBin32Sto16Ux8 isn't supported in angr.

   * ref with clang -O1 works fine, but of course isn't sufficient for
     avx-vs.-ref tests.

2021.09.04 tests with angr-dev: Unrolling now works fine thanks to
https://github.com/angr/angr/pull/2887. avx=ref with both compilers,
ref=ref across compilers.
