RUN: llvm-dwp %p/../Inputs/compress/a.dwo -o %t RUN: llvm-dwarfdump %t | FileCheck %s REQUIRES: zlib Simple test built from this input which produces DWARF long enough to be compressed in the .[z]debug_info section: void f(int a, int b, int c, int d) { } Since the compression is pretty orthogonal, we're not trying to test that the compression library functioned correctly, just that dwp used it to decompress the section - so test a few simple features and be done with it.
