Version v2.1.2

[wtdcode]

2.1.2 is a patch release to mainly resolve the stability issue of the 2.1.0 release series and fix a few distribution issues. All users of Unicorn are expected to upgrade.

Highlights

• macOS arm64 no longer provides binary wheels due to a feature missing from Github Action runners.
• py3.8 support is brought back, python2 wheels are built and test as well and we migrate to cibuildwheel! @Antelox
• Several polish to python bindings and implement new API. @elicn @droe
• Revert previous break changes that return UC_ERR_ARG for non-existing registers. Now this prints a warning. We urge all users relying on this behavior to fix code as soon as possible.
• Fix several segment faults, including a few long-standing random segfault issues.
• Revive previous unicorn 1 test suite and related refactoring. @elicn @Antelox
• Optimize memory handling and notdirty writes for faster memory access and snapshots, especially useful for fuzzing. @PhilippTakacs
• RISC-V API updates. @apparentlymart
• fix UC_HOOK_MEM_READ on aarch64. @glennsec
• Support UC_TCG_OP_FLAG_CMP for ARM @dotCirill
• An alternative tag prefixed with "v" is added for golang compatibility.

Fix & Improvements

• Implement UC_ARM64_REG_WSP
• Several fixes on arm64 macos @tbodt
• reg_read_batch and reg_write_batch @hsa1as
• Fix pc sync issue for SPARC, MIPS, x86. This also fixes PC sync issue within UC_HOOK_BLOCK hooks.
• Allow cmake to install files on Windows and allow cmake not to generate Unicorn 1 style all-in-one objects archive
• Make i386 instructions RDTSC and RDTSCP hookable @t0rr3sp3dr0
• Allow Statically Linking in Go @t0rr3sp3dr0
• Rust bindings improvements @Sanae6
• Patch multiple UC_HOOK_MEM callbacks for unaligned access @Michael-c0de
• Fix UC_MEM_FETCH_PROT for data read
• Remove more Unicorn 1 hacks to improve performance.
• Docs & unit test updates. @saicao
• Allow uc_ctl_set_page_size() for arm64 @droe
• Musl builds @clan
• mips16 fix @ZakDanger
• Fix UC_HOOK_MEM on arm32 @xndcn

Full Changelog: 2.1.1...2.1.2

As usual, thanks to all contributors and sorry if I missed your name here (please tell me @wtdcode !).

Lastly and personally, I would like to express my big thanks to @Antelox @elicn and @PhilippTakacs for spending lots of time improving Unicorn Engine. Also, there are a few big pull requests adding new architectures (RH850, TCI, LoongArch64, AVR) and I will actively push them to 2.2.0.
