Bug 19724 – Regression: wrong order of linker arguments, again: -L-l before -L--start-group

When explicitly specifying libraries to be passed to the linker, they are reordered to the end. That's bad, because it breaks -L=--start-group and -L=--end-group. Linker groups define a set of libraries that are evaluated circularly until all symbols are resolved. Repro: touch test.d dmd -L=--start-group -L=-lfoo -L=--end-group Expected: cc -Xlinker --start-group -lfoo -Xlinker --end-group Actual: cc -Xlinker --start-group -Xlinker --end-group -lfoo This is obviously quite useless.

@FeepingCreature created dlang/dmd pull request #9426 "Fix Issue 19724: wrong order of linker flags, take 2" fixing this issue: - Fix Issue 19724. On Linux, don't reorder -L-l flags to be before other -L flags. Only reorder -L-L. This keeps -L-l libs and linker flags that may affect the interpretation of -l flags such as --start-group ordered correctly. https://github.com/dlang/dmd/pull/9426
