b (Limit-optimizations)
Limits optimizations.
b
size
size
is a positive decimal integer.
Default
Having more than 2500 intermediate language statements in a function
causes the compiler to disable some global optimizations.
Discussion
As function size increases, the compiler slows. The b (Limit-
optimizations) option allows you to alter the threshold at which
optimizations are scaled back when functions are too large to compile
quickly.
Example
In the following example, the b (Limit-optimizations) option forces
suppression of global optimization for functions in
proto.c larger than
2000 intermediate language statements.
