debug_line-relative_path.s 2.08 KB
# This tests handling of debug info with fully relative paths, such as those
# produced by "clang -fdebug-compilation-dir <something-relative>". This is one
# of the techniques used to produce "relocatable" debug info.

# REQUIRES: x86

# RUN: llvm-mc -filetype=obj -triple x86_64-pc-linux -o %t %s
# RUN: %lldb %t -o "image dump line-table t.c" | FileCheck %s

# CHECK: 0x0000000000000000: {{q[\\/]w[\\/]e[\\/]r[\\/]t}}.c:1
