# REQUIRES: x86-registered-target

## Test that the relative names option to llvm-symbolizer works properly.
## See llvm/docs/CommandGuide/llvm-symbolizer.rst for commands
## that would produce this test case

# RUN: llvm-mc %s -filetype obj -triple x86_64-pc-linux -o %t.o

# RUN: llvm-symbolizer 0 --relativenames --obj=%t.o \
# RUN:    | FileCheck %s -DDIR=%p --check-prefix=RELATIVENAMES

## A basic correctness check for default.
# RUN: llvm-symbolizer 0 --obj=%t.o \
# RUN:    | FileCheck %s -DDIR=%p --check-prefix=ABSOLUTENAMES

## Ensure last option wins.
# RUN: llvm-symbolizer 0 --basenames --relativenames --obj=%t.o \
# RUN:    | FileCheck %s -DDIR=%p --check-prefix=RELATIVENAMES
# RUN: llvm-symbolizer 0 --relativenames --basenames --obj=%t.o \
# RUN:    | FileCheck %s --check-prefix=BASENAMES

# ABSOLUTENAMES: {{\\|/}}tmp{{\\|/}}foo{{\\|/}}relativenames.s:4
# RELATIVENAMES: {{^}}foo{{\\|/}}relativenames.s:4
# BASENAMES: {{^}}relativenames.s:4

##  Provide just enough info in debug info for the symbolizer
