Technical tradeoffs

  • • Backporting the patch ensures stability for the 2.46 release, but it may introduce unforeseen regressions.
  • • The fix is limited to Linux/x86-64 and Linux/aarch64 due to test dependencies.
  • • The patch might increase the complexity of the linker code.

[2.46 PATCH]: ld: Maintain the input file order

This patch backports a fix from the master branch to the binutils 2.46 branch to address an issue where the linker (ld) reorders input files when linking with Link-Time Optimization (LTO) and linker scripts. Specifically, when libraries are included via the GROUP command in a linker script (e.g., -lm pulling in /usr/lib64/libm.a), the order of archive members can be changed during LTO rescan. This is important for maintaining the correct symbol resolution order and preventing unexpected linking errors.
