Nit: here and below. The more common style we use in newer llvm-readobj tests is as suggested. The idea being that the `| \` at the end of the first line indicates a new command follows on the next line, while the indentation of the second indicates it's a continuation of a chain from the previous line.
```suggestion
# RUN:   --sframe=.sframe_6b --sframe=.sframe_header %t.1 2>&1 | \
# RUN:   FileCheck %s --strict-whitespace --match-full-lines \
