SPM does not control the swift driver invocation in all cases #6575
Description
Description
When building without the integrated swift driver and without swift module emission separated, SPM will rely on the LLBuild hardcoded swift driver invocation which does not take into account any of the flags when building code.
The generated command invocation is embedded into LLBuild statically and does not evolve with SPM. As per @dmbryson this should not be relied upon.
Expected behavior
SPM would be able to control the formulation of the command line
Actual behavior
The command line is encoded into the LLBuild codebase.
