# This test verifies that an empty range list in the .debug_ranges section
 |

# doesn't crash llvm-dsymutil. As clang does not produce this kind of debug
 | 
						|
# info anymore, we used this hand-crafted assembly file to produce a testcase
 |

# Compile with:
 | 
						|
#        llvm-mc -triple x86_64-apple-darwin -filetype=obj -o 1.o empty_range.o
 | 
						|
 | 
						|
# RUN: llvm-dsymutil -f -y %p/dummy-debug-map.map -oso-prepend-path %p/../Inputs/empty_range -o - | llvm-dwarfdump -debug-dump=info - | FileCheck %s
