M-Lint and mlint Enhancements and Changes

The M-Lint code analyzer is now built into the Editor/Debugger where it continuously

checks your code for problems and recommends modifications to maximize performance

and maintainability. For details, see “M-Lint Automatic Code Analyzer Checks for

Problems and Suggests Improvements” on page 22-7.

Compatibility Considerations

The mlint function has changed slightly to support its use in the Editor/Debugger.

Specifically, the results returned from mlint with the -id option are of a different

form than for previous versions. If you rely on the exact values, you need to make

modifications.

For example, this is the form of a message returned in R2006a: L 22 (C 1-9)

2:AssignmentNotUsed : The value assigned here to variable

'nothandle' might never be used.

This is the form of the message from R14SP3: 22 (C 1-9)

InefficientUsage:AssignmentNotUsed : The value assigned here to

variable 'nothandle' might never be used.

There is now a numeric identifier, followed by the category, for example:

2:AssignmentNotUsed.

If you do rely on the exact values, note that there have been very few changes to the

message text itself. For example, both R14SP3 and R2006a use the same text: The

value assigned here to variable 'nothandle' might never be used.

Because of improvements being made to mlint, the values returned using the -id option

are expected to change in the next version as well, particularly the numeric identifier and

category form. Do not rely on the exact values returned using mlint with the -id option

or you will probably need to make modifications.

Profiling Enhancements

nohistory Option Added to profile Function

Use the new profile -nohistory option after having previously set the -history

option to disable further recording of history (exact sequence of function calls). All other

profiling statistics continue to accumulate.
