LLVM-LOCSTATS(1) LLVM LLVM-LOCSTATS(1)

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 50-59% shows the number and the percentage of DIEs where the location information is between 50 and 59 percentage of its scope covered.

OPTIONS

Calculate the location statistics only for local variables.

Calculate the location statistics only for formal parameters.

Ignore the location statistics on locations containing the debug entry values DWARF operation.

EXIT STATUS

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