Syntax

Linux and Mac OS X:

-vec-report[n]

Windows:

/Qvec-report[n]

Arguments

n

Is a value denoting which diagnostic messages to report. Possible values are:

0	Tells the vectorizer to report no diagnostic information.
1	Tells the vectorizer to report on vectorized loops.
2	Tells the vectorizer to report on vectorized and non-vectorized loops.
3	Tells the vectorizer to report on vectorized and non-vectorized loops and any proven or assumed data dependences.
4	Tells the vectorizer to report on non-vectorized loops.
5	Tells the vectorizer to report on non-vectorized loops and the reason why they were not vectorized.

Default

-vec-report1
or/Qvec-report1

If the vectorizer has been enabled and you do not specify n, the compiler reports diagnostics on vectorized loops. If you do not specify the option on the command line, the default is to display no messages.

Description

This option controls the diagnostic information reported by the vectorizer. The vectorizer report is sent to stdout.

If you do not specify n, it is the same as specifying -vec-report1 (Linux and Mac OS X) or /Qvec-report1 (Windows).

Alternate Options

None
