undertaker(1)

Coverage Options:

-O: specify the output mode of generated configurations

kconfig
generated partial kconfig configuration (default)
stdout
print on stdout the found configurations
cpp
print on stdout cpp -D command line arguments
exec:cmd
pipe file for every configuration to cmd
model
print all options which are in the configuration space
all
dump every assigned symbol (both items and code blocks)

-C: specify coverage algorithm

simple

- relative simple and fast algorithm (default)

min

- slow but generates less configuration sets

Specifying Files:

You can specify one or many files (the format is according to the job (-j) which should be done. If you specify - as file, undertaker will load models and whitelist and read files from stdin (interactive).

please specify a file to scan or a worklist

`undertaker' analyzes conditional C code with #ifdefs.

Usage: undertaker [OPTIONS] <file..>

-V

print version information

-v

increase the log level (more verbose)

-q

decrease the log level (less verbose)

-m

specify the model(s) (directory or file)

-M

specify the main model

-w

specify a whitelist

-b

specify a worklist (batch mode)

-t

specify count of parallel processes

-I

add an include path for #include directives

-j

specify the jobs which should be done
dead
dead/undead file analysis (default)
coverage
coverage file analysis
cpppc
CPP Preconditions for whole file
blockpc: Block precondition (format: <file>:<line>
<column>)
symbolpc
Symbol precondition (format <symbol>)
checkexpr
Find a configuration that satisfies expression
interesting
Find related items (negated items are not in the model)
