Summary of Changes

Hello @waruqi, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request addresses an issue related to how configuration flags are applied within the build system. It specifically reorders the timing of when user-defined configuration flags are incorporated into both the compilation and linking processes. By moving the application of these flags to a later stage, the change aims to ensure correct precedence and behavior, preventing earlier-defined flags from being inadvertently overridden or applied out of sequence.

Highlights

  • Compiler Flag Application Order: The application of user configuration flags in the compiler.lua module has been reordered to occur at a later stage in the compilation flag generation process.
  • Linker Flag Application Order: Similarly, the application of user configuration flags in the linker.lua module has been reordered to occur at a later stage in the linking flag generation process.
  • Flag Precedence: This reordering ensures that user-defined configuration flags are applied after target-specific and argument-based flags, potentially resolving issues related to flag precedence or unexpected overrides, as indicated by the linked issue.

Code Review

This pull request modifies the order in which compiler and linker flags are applied, ensuring that global configuration flags have the highest priority. The changes in compiler.lua and linker.lua move the application of user-configured flags to be last in the flag processing sequence, just before preprocessing. This correctly allows global flags set via xmake config to override any other flags defined in targets or toolchains. The implementation is straightforward, consistent across both files, and effectively addresses the intended goal. The changes look correct and well-implemented.
