| Abbreviation | RF | |
| Arguments | A file name enclosed in parentheses. | |
| Default | None. | |
| µVision | Options — C166 — Global Register Coloring. | |
| Description | The REGFILE directive instructs the compiler to use a register definition file for global register optimization. The register definition file specifies the registers used by external functions. Using this information, the compiler can optimize the use of the general purpose registers. This feature enables global program-wide register optimization. | |
| Example |
C166 SAMPLE.C REGFILE(sample.reg) #pragma REGFILE(sample.reg) |
