This is recommit of llvm/llvm-project#92660, reverted in llvm/llvm-project#94424. Original commit message is below. After commit1792852f86([symbolizer] Change reaction on invalid input) llvm-symbolizer issues an error on malformed command instead of echoing it to the standard output, as in previous versions. It turns out this behavior broke a use case when echoing was used to check if llvm-symbolizer is working (1792852f86 (commitcomment-142161925)). With this change an empty line as input is not considered as an error anymore and does not produce any output on stderr. llvm-symbolizer still respond on empty line with line not found, this is consistent with GNU addr2line.
