register_coloring
Description:
Controls whether the use of register coloring.
Compatibility:
This pragma is compatible with the following platform targets:
Prototype:
#pragma register_coloring on | off | reset
Remarks:
When this pragma is on, the compiler uses a single register to hold the value of more than one variable if those variables are never used in the same statement to improve a program's performance.
TIP
Turn this option off when debugging a program.
This pragma corresponds to the Register Coloring option in the x86 Codegen panel. To check whether this option is on, use __option (register_coloring), described in "Checking Options."
See also "no_register_coloring."
