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