# llvm-mc normally emits an empty .text section into every object file. Since
|
|
# nothing actually refers to it via a relocation, it doesn't have any associated
|
|
# symbols (thus nor can anything refer to it via a relocation, making it safe to
|
|
# merge with the empty section in the other input file). Here we check that the
|
|
# only two sections merged are the two empty sections and the sections with only
|
|
# STB_LOCAL or STV_HIDDEN symbols. The dynsym entries should have prevented
|
|
# anything else from being merged.
