4.6.5.2 G: Produce Debugging Information Option
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 64 KB. |
-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.
