# llvm-locstats-13(1)

calculate statistics on DWARF debug location

## NAME

llvm-locstats - calculate statistics on DWARF debug location

## SYNOPSIS

**llvm-locstats** \[*options*\] \[*filename*\]

## DESCRIPTION

**llvm-locstats** works like a wrapper around **llvm-dwarfdump**. It parses **llvm-dwarfdump** statistics regarding debug location by pretty printing it in a more human readable way.

The line 0% shows the number and the percentage of DIEs with no location information, but the line 100% shows the information for DIEs where there is location information in all code section bytes (where the variable or parameter is in the scope). The line \[50%,60%) shows the number and the percentage of DIEs where the location information is between 50 and 60 percentage of its scope covered.

## OPTIONS

- **--only-variables**

  calculate the location statistics only for local variables

- **--only-formal-parameters**

  calculate the location statistics only for formal parameters

- **--ignore-debug-entry-values**

  ignore the location statistics on locations containing the debug entry values DWARF operation

- **--draw-plot**

  make histogram of location buckets generated (requires matplotlib)

- **--compare**

  compare the debug location coverage on two files provided, and draw a plot showing the difference (requires matplotlib)

## EXIT STATUS

**llvm-locstats** returns 0 if the input file were parsed successfully. Otherwise, it returns 1.

## EXAMPLE 1

Pretty print the location coverage on the standard output.

```
llvm-locstats a.out

## EXAMPLE 2

Generate a plot as an image file.

```
llvm-locstats --draw-plot file1.out
```

\[image\]

## EXAMPLE 3

Generate a plot as an image file showing the difference in the debug location coverage.

```
llvm-locstats --compare file1.out file1.withentryvals.out
```

\[image\]
