Enables or disables optimizations for specific functions.
#pragma optimize("", on|off) |
The compiler ignores first argument values. Valid second arguments for optimize are given below.
off |
disables optimization |
on |
enables optimization |
The optimize pragma is used to enable or disable optimizations for specific functions. Specifying #pragma optimize("", off) disables optimization until either the compiler finds a matching #pragma optimize("", on) statement or until the compiler reaches the end of the translation unit.
Example 1: Disabling optimization for a single function using the #pragma optimize
In the following example, optimizations are disabled for the alpha() function but not for omega().
#pragma optimize("", off)
alpha() {
...
}
#pragma optimize("", on)
omega() {
...
}
Example 2: Disabling optimization for all functions using the #pragma optimize
In the following example, optimizations are disabled for both the alpha() and omega() functions.
#pragma optimize("", off)
alpha() {
...
}
omega() {
...
}
