## Check that the --debug-vars option works for simple register locations, when
## using DWARF4 debug info, with multiple functions in one section. Check that
## the live-range lines are rendered correctly when using the --no-show-raw-insn,
## --line-numbers and --source options. These do not affect the DWARF parsing
## used by --debug-vars, but do add extra lines or columns to the output, so we
## test to make sure the live ranges are still displayed correctly.
## Generated with this compile command, with the source code in Inputs/debug.c:
## clang --target=arm--none-eabi -march=armv7-a -c debug.c -O1 -gdwarf-4 -S -o -

# RUN: llvm-objdump - -d --debug-vars | \
# RUN: FileCheck %s --check-prefix=RAW --strict-whitespace
## Check that passing the default value for --debug-vars-indent (40) makes no
## change to the output.

## An optional argument to the --debug-vars= option can be used to switch
## between unicode and ascii output (with unicode being the default).

## Note that llvm-objdump emits tab characters in the disassembly, assuming an
## 8-byte tab stop, so these might not look aligned in a text editor.
