Syntax
Linux and Mac OS X: | -inline-factor=n -no-inline-factor |
Windows: | /Qinline-factor=n /Qinline-factor- |
Arguments
n |
Is a positive integer specifying the percentage value. The default value is 100 (a factor of 1). |
Default
-no-inline-factor |
The compiler uses default heuristics for inline routine expansion. |
Description
This option specifies the percentage multiplier that should be applied to all inlining options that define upper limits:
-inline-max-size and /Qinline-max-size
-inline-max-total-size and /Qinline-max-total-size
-inline-max-per-routine and /Qinline-max-per-routine
-inline-max-per-compile and /Qinline-max-per-compile
This option takes the default value for each of the above options and multiplies it by n divided by 100. For example, if 200 is specified, all inlining options that define upper limits are multiplied by a factor of 2. This option is useful if you do not want to individually increase each option limit.
If you specify -no-inline-factor (Linux and Mac OS X) or /Qinline-factor- (Windows), the following occurs:
Every function is considered to be a small or medium function; there are no large functions.
There is no limit to the size a routine may grow when inline expansion is performed.
There is no limit to the number of times some routine may be inlined into a particular routine.
There is no limit to the number of times inlining can be applied to a compilation unit.
To see compiler values for important inlining limits, specify compiler option -opt-report (Linux and Mac OS X) or /Qopt-report (Windows).
Caution
When you use this option to increase default limits, the compiler may do so much additional inlining that it runs out of memory and terminates with an "out of memory" message.
