When configuring CMake builds, carefully select compiler and linker flags that optimize for performance while maintaining cross-platform compatibility. Performance-oriented flags can significantly impact runtime speed, binary size, and resource utilization, but must be applied conditionally based on the target platform and compiler.

Reviewer Prompt

When configuring CMake builds, carefully select compiler and linker flags that optimize for performance while maintaining cross-platform compatibility. Performance-oriented flags can significantly impact runtime speed, binary size, and resource utilization, but must be applied conditionally based on the target platform and compiler.

Key practices:

  • Research the performance implications of compilation flags before applying them (e.g., DYNAMIC_EXECUTION=0 may slow down WebAssembly bindings)
  • Use conditional compilation to apply platform-specific optimizations (e.g., --gc-sections for GCC/Clang vs --dead_strip for AppleClang)
  • Enable standard performance flags like CMAKE_POSITION_INDEPENDENT_CODE ON for better code generation
  • Consider alternative optimization strategies when default flags cause performance regressions

Example of conditional linker optimization:

target_link_options(yoga PRIVATE
    # Discard unused sections
    $<$<CONFIG:RELEASE>:$<$<CXX_COMPILER_ID:Clang,GNU>:-Wl,--gc-sections>>
    $<$<CONFIG:RELEASE>:$<$<CXX_COMPILER_ID:AppleClang>:-Wl,-dead_strip>>)

This approach ensures optimal performance across different build environments while avoiding platform-specific build failures.
