This PR enhances the existing ARM support in snappy-java by adding ARM-specific build optimizations and improving documentation clarity around ARM compatibility.
Background
The snappy-java project already has excellent ARM support with native libraries for multiple ARM architectures (AArch64, ARMv5, ARMv6, ARMv7) across Linux, macOS, Windows, and Android. However, the build system was missing ARM-specific compiler optimizations that could improve performance on ARM platforms.
Changes Made
Build Optimizations
Enhanced the Makefile to include ARM-specific compiler flags similar to the existing x86_64 SSE2 optimizations:
-march=armv8-afor optimal ARMv8-A instruction set targeting-march=armv7-a -mfpu=neonto enable NEON SIMD instructions for better performanceDocker Infrastructure
Added a new ARM-compatible Docker image (
Dockerfile.rockylinux8-multiarch) to replace older x86-only build environments:Documentation
Updated README.md to explicitly highlight ARM architecture support:
Performance Impact
These optimizations align ARM builds with the existing x86_64 optimization strategy, ensuring ARM users get comparable performance benefits from architecture-specific instruction sets and SIMD capabilities.
Testing
The project's comprehensive native library support means ARM users already have full functionality - these changes simply ensure they get optimal performance.
