# This test checks that source code location is shown correctly
# when single split file debug information is used (when .dwo sections are in .o files).
#
# single-file-split-dwarf.yaml and single-file-split-dwarf.o.yaml are
# reduced yaml files produces from the object file and the corresponding executable.
#
# The following code was used initially:
# int main() {
#   return 0;
# }
# 
# void foo() {
# }
#
# Invocation used to produce .o file was:
# clang test.cpp -gdwarf-5 -gsplit-dwarf=single -c -o test.o -v
#
# The full invocation used to produce the executable was:
# "/usr/local/bin/ld" -z relro --hash-style=gnu --eh-frame-hdr -m elf_x86_64 -dynamic-linker
#  /lib64/ld-linux-x86-64.so.2 -o test /usr/lib/gcc/x86_64-linux-gnu/7.3.0/../../../x86_64-linux-gnu/crt1.o
