This patch updates tests using llvm-readobj and llvm-readelf, because soon reading from stdin will be achievable only via a '-' as described here: https://bugs.llvm.org/show_bug.cgi?id=46400. Patch with changes to llvm-readobj behavior is here: https://reviews.llvm.org/D83704 Differential Revision: https://reviews.llvm.org/D83912 Reviewed by: jhenderson, MaskRay, grimar

# Check that a relocation is not emitted for a symbol difference which has
|
|
# been folded to a fixup with an absolute value. This can happen when a
|
|
# difference expression refers to two symbols, at least one of which is
|
|
# not defined at the point it is referenced. Then during *assembler*
|
|
# relaxation when both symbols have become defined the difference may be folded
|
|
# down to a fixup simply containing the absolute value. We want to ensure that
|
|
# we don't force a relocation to be emitted for this absolute value even
|
|
# when linker relaxation is enabled. The reason for this is that one instance
|
|
# where this pattern appears in in the .eh_frame section (the CIE 'length'
|
|
# field), and the .eh_frame section cannot be parsed by the linker unless the
|
|
# fixup has been resolved to a concrete value instead of a relocation.
