The -gformat option instructs the compiler to produce additional information, which can be used by
hardware tools to debug your program.
The support formats are tabulated below.
| Format | Debugging file format |
|---|---|
-gcoff |
COFF |
-gdwarf-3 |
ELF/Dwarf release 3 |
-ginhx32 |
Intel HEX with extended linear address records, allowing use of addresses beyond 64kB |
-ginhx032 |
INHX32 with initialization of upper address to zero |
By default, the compiler produces Dwarf release 3 files.
The compiler supports the use of this option with the optimizers enabled, making it possible to debug optimized code; however, the shortcuts taken by optimized code may occasionally produce surprising results, such as variables that do not exist and flow control that changes unexpectedly.
