llvm-locstats - calculate statistics on DWARF debug location
============================================================
.. program:: llvm-locstats
SYNOPSIS
--------
:program:`llvm-locstats` [*options*] [*filename*]
DESCRIPTION
-----------
:program:`llvm-locstats` works like a wrapper around :program:`llvm-dwarfdump`.
It parses :program:`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 50-59% shows the number and the percentage of DIEs
where the location information is between 50 and 59 percentage of its scope
covered.
OPTIONS
-------
.. option:: -only-variables
Calculate the location statistics only for local variables.
.. option:: -only-formal-parameters
Calculate the location statistics only for formal parameters.
.. option:: -ignore-debug-entry-values
Ignore the location statistics on locations containing the
debug entry values DWARF operation.
EXIT STATUS
-----------
:program:`llvm-locstats` returns 0 if the input file were parsed
successfully. Otherwise, it returns 1.
OUTPUT EXAMPLE
--------------
.. code-block:: none
