The test-case was already self-contained and had little context-sensitiveness
due to the line-oriented nature, so I didn't expect you to need this.

This is a bit worrying. Surely you didn't think this would ever be needed, for
a test-case where the nature of the failure is that it emits a subroutine call
to link_error()? Again, the regression is a missing optimization of sincos for
a soft-float target, as already mentioned in the summary and description.
Anyway, one reduced test-case coming up.
