llvm-link and clang both have a -o option with similar meaning, but the help text describes it differently.
llvm-link describes it as:
and clang describes it as
with no ‘=’ between the option and the parameter.
When I try using the command line options library, it comes out the same way as llvm-link, with no apparent method of getting it to come out the other way. This might be just a minor cosmetic question, but I’ve a feeling it actually points to a significant gap in my understanding of the command line options library, because when I tried checking the clang source code for the answer, the only relevant reference I could find was in some configuration or DSL file whose syntax and function I’m not familiar with.
How exactly is clang getting that effect?
