- Update to version 0.4.39:
- Security: Fix error message printing buffer overflow leading
to possible code execution in orcc with specific input files
(CVE-2024-40897). This only affects developers and CI
environments using orcc, not users of liborc (boo#1228184)
- div255w: fix off-by-one error in the implementations
- x86: only run AVX detection if xgetbv is available
- x86: fix AVX detection by implementing the check recommended
by Intel
- Only enable JIT compilation on Apple arm64 if running on macOS,
fixes crashes on iOS
- Fix potential crash in emulation mode if logging is enabled
- Handle undefined TARGET_OS_OSX correctly
- orconce: Fix typo in GCC __sync-based implementation
- orconce: Fix usage of __STDC_NO_ATOMICS__
- Fix build with MSVC 17.10 + C11
- Support stack unwinding on Windows
- Major opcode and instruction set code clean-ups and refactoring
- Refactor allocation and chunk initialization of code regions
- Fall back to emulation on Linux if JIT support is not
available, e.g. because of SELinux sandboxing or noexec
mounting)

- Update to version 0.4.29:
+ PowerPC: Support ELFv2 ABI (A. Wilcox) and ppc64le.
+ Mips backend: only enable if the DSPr2 ASE is present.
+ Windows and MSVC build fixes.
+ orccpu-arm: Allow 'cpuinfo' fallback on non-android.
+ pkg-config file for orc-test library.
+ orcc: add --decorator command line argument to add function
decorators in header files.
+ meson:
- Make orcc detectable from other subprojects.
- Add options to disable tests, docs, benchmarks, examples,
tools, etc.
- Misc. other fixes.
- Pass orc-test=disabled, examples=disabled and tests=disabled to
meson, and drop meson_tests. Tests consistantly fails on the
buildservice and consistantly succedes when building locally,
hence trying to build them on the obs is pointless.
