Runtime coverage analysis
Covered functions
403
Functions that are reachable but not covered
53
Reachable functions
216
Percentage of reachable functions covered
75.46%
NB:
The sum of
covered functions
and
functions that are reachable but not covered
need not be
Reachable functions
. This is because the reachability analysis is an approximation and thus at runtime some functions may be covered that are not included in the reachability analysis. This is a limitation our of our static analysis capabilities.
Warning:
The amount of covered functions are larger than the amount of reachable functions. This means the functions covered at runtime is larger than those extracted using static analysis. This is likely a result of the static analysis component failing to extract the right callgraph or the coverage runtime being compiled with sanitizerse in code that the static analysis has not analysed. This can happen if lto/gold is not used in all places that coverage instrumentation is used.

Runtime coverage analysis
Covered functions
6391
Functions that are reachable but not covered
443
Reachable functions
1500
Percentage of reachable functions covered
70.47%
NB:
The sum of
covered functions
and
functions that are reachable but not covered
need not be
Reachable functions
. This is because the reachability analysis is an approximation and thus at runtime some functions may be covered that are not included in the reachability analysis. This is a limitation our of our static analysis capabilities.
Warning:
The amount of covered functions are larger than the amount of reachable functions. This means the functions covered at runtime is larger than those extracted using static analysis. This is likely a result of the static analysis component failing to extract the right callgraph or the coverage runtime being compiled with sanitizerse in code that the static analysis has not analysed. This can happen if lto/gold is not used in all places that coverage instrumentation is used.

Runtime coverage analysis
Covered functions
286
Functions that are reachable but not covered
34
Reachable functions
167
Percentage of reachable functions covered
79.64%
NB:
The sum of
covered functions
and
functions that are reachable but not covered
need not be
Reachable functions
. This is because the reachability analysis is an approximation and thus at runtime some functions may be covered that are not included in the reachability analysis. This is a limitation our of our static analysis capabilities.
Warning:
The amount of covered functions are larger than the amount of reachable functions. This means the functions covered at runtime is larger than those extracted using static analysis. This is likely a result of the static analysis component failing to extract the right callgraph or the coverage runtime being compiled with sanitizerse in code that the static analysis has not analysed. This can happen if lto/gold is not used in all places that coverage instrumentation is used.

Runtime coverage analysis
Covered functions
2190
Functions that are reachable but not covered
70
Reachable functions
439
Percentage of reachable functions covered
84.05%
NB:
The sum of
covered functions
and
functions that are reachable but not covered
need not be
Reachable functions
. This is because the reachability analysis is an approximation and thus at runtime some functions may be covered that are not included in the reachability analysis. This is a limitation our of our static analysis capabilities.
Warning:
The amount of covered functions are larger than the amount of reachable functions. This means the functions covered at runtime is larger than those extracted using static analysis. This is likely a result of the static analysis component failing to extract the right callgraph or the coverage runtime being compiled with sanitizerse in code that the static analysis has not analysed. This can happen if lto/gold is not used in all places that coverage instrumentation is used.

Warning:
The amount of covered functions are larger than the amount of reachable functions. This means the functions covered at runtime is larger than those extracted using static analysis. This is likely a result of the static analysis component failing to extract the right callgraph or the coverage runtime being compiled with sanitizerse in code that the static analysis has not analysed.

Reachable functions

Percentage of reachable functions covered
86.11%
NB:
The sum of
covered functions
and
functions that are reachable but not covered
need not be
Reachable functions
. This is because the reachability analysis is an approximation and thus at runtime some functions may be covered that are not included in the reachability analysis. This is a limitation our of our static analysis capabilities.
Warning:
The amount of covered functions are larger than the amount of reachable functions. This means the functions covered at runtime is larger than those extracted using static analysis. This is likely a result of the static analysis component failing to extract the right callgraph or the coverage runtime being compiled with sanitizerse in code that the static analysis has not analysed. This can happen if lto/gold is not used in all places that coverage instrumentation is used.

Runtime coverage analysis
Covered functions
1123
Functions that are reachable but not covered
23
Reachable functions
187
Percentage of reachable functions covered
87.7%
NB:
The sum of
covered functions
and
functions that are reachable but not covered
need not be
Reachable functions
. This is because the reachability analysis is an approximation and thus at runtime some functions may be covered that are not included in the reachability analysis. This is a limitation our of our static analysis capabilities.
Warning:
The amount of covered functions are larger than the amount of reachable functions. This means the functions covered at runtime is larger than those extracted using static analysis. This is likely a result of the static analysis component failing to extract the right callgraph or the coverage runtime being compiled with sanitizerse in code that the static analysis has not analysed. This can happen if lto/gold is not used in all places that coverage instrumentation is used.

Runtime coverage analysis
Covered functions
752
Functions that are reachable but not covered
82
Reachable functions
433
Percentage of reachable functions covered
81.06%
NB:
The sum of
covered functions
and
functions that are reachable but not covered
need not be
Reachable functions
. This is because the reachability analysis is an approximation and thus at runtime some functions may be covered that are not included in the reachability analysis. This is a limitation our of our static analysis capabilities.
Warning:
The amount of covered functions are larger than the amount of reachable functions. This means the functions covered at runtime is larger than those extracted using static analysis. This is likely a result of the static analysis component failing to extract the right callgraph or the coverage runtime being compiled with sanitizerse in code that the static analysis has not analysed. This can happen if lto/gold is not used in all places that coverage instrumentation is used.

The following is the call tree with color coding for whichfunctions are hit/not hit. This info is based on the coverageachieved of all fuzzers together and not just this specificfuzzer. This should change in the future to be per-fuzzer-basis.

Reachable functions

Percentage of reachable functions covered
81.82%
NB:
The sum of
covered functions
and
functions that are reachable but not covered
need not be
Reachable functions
. This is because the reachability analysis is an approximation and thus at runtime some functions may be covered that are not included in the reachability analysis. This is a limitation our of our static analysis capabilities.
Warning:
The amount of covered functions are larger than the amount of reachable functions. This means the functions covered at runtime is larger than those extracted using static analysis. This is likely a result of the static analysis component failing to extract the right callgraph or the coverage runtime being compiled with sanitizerse in code that the static analysis has not analysed. This can happen if lto/gold is not used in all places that coverage instrumentation is used.

Runtime coverage analysis

Reachable functions
274
Percentage of reachable functions covered
82.85%
NB:
The sum of

and
functions that are reachable but not covered
need not be
Reachable functions
. This is because the reachability analysis is an approximation and thus at runtime some functions may be covered that are not included in the reachability analysis. This is a limitation our of our static analysis capabilities.
Warning:
The amount of covered functions are larger than the amount of reachable functions. This means the functions covered at runtime is larger than those extracted using static analysis. This is likely a result of the static analysis component failing to extract the right callgraph or the coverage runtime being compiled with sanitizerse in code that the static analysis has not analysed. This can happen if lto/gold is not used in all places that coverage instrumentation is used.

Analyses and suggestions
Optimal target analysis
Remaining optimal interesting functions
The following table shows a list of functions that are optimal targets. Optimal targets are identified by finding the functions that in combination reaches a high amount of code coverage.
| Func name | Functions filename | Arg count | Args | Function depth | hitcount | instr count | bb count | cyclomatic complexity | Reachable functions | Incoming references | total cyclomatic complexity | Unreached complexity |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
JS::GlobalObject::initialize_global_object()

Implementing fuzzers that target the above functions will improve reachability such that it becomes:
Functions statically reachable by fuzzers
6946/40922
Cyclomatic complexity statically reachable by fuzzers
28618 / 136492
All functions overview
The status of all functions in the project will be as follows if you implement fuzzers for these functions
| Func name | Functions filename | Args | Function call depth | Reached by Fuzzers | Fuzzers runtime hit | Func lines hit % | I Count | BB Count | Cyclomatic complexity | Functions reached | Reached by functions | Accumulated cyclomatic complexity | Undiscovered complexity |
