Thanks, I need to update GCC and test. Up to version 12, the line table was still version 3. In the meantime, you will need to compile/link with the "-gdwarf-4" option.

compuphase commented 4 months ago

Can you give me more information on the command line options for GCC?

I use GCC 13.2.1 (like you), and a build a sample program with this:

arm-none-eabi-gcc -gdwarf-5 -mcpu=cortex-m3 -mthumb -o blinky.elf blinky.c -nostartfiles -Wl,-T,STM32F103x8.ld

With objdump, I can confirm that the symbolic information is in DWARF version 5:

arm-none-eabi-objdump --dwarf=info blinky.elf
blinky.elf:     file format elf32-littlearm

Contents of the .debug_info section:

However, the line number table (.debug_line) still uses version 3 in my case:

arm-none-eabi-objdump --dwarf=rawline blinky.elf
blinky.elf:     file format elf32-littlearm

Raw dump of debug contents of section .debug_line:

I have tried compiling in C++ mode, but with the same result (.debug_line table still in version 3). So there appears to be a compiler option that causes GCC to emit the .debug_line table in version 5. I am running these tests on Windows, by the way.

compuphase commented 4 months ago

I found a way to create a version 5 .debug_line table: add the option -Wa,-gdwarf-5. It turns out that the .debug_line table is often created by the assembler.

compuphase commented 4 months ago

Support for DWARF version 5 is added in commit 67feb1954b3f9b8586104c6fc6f75db6ade88161.
