SDCC Debug information!!! #2

Hi, Philipp!

I've recently added the result of my work on STVD-SDCC integration!

The toollset works well and able to build STVD project with SDCC.

Here are toolchain settings: stvd-settings

But when I try to start the debug session, I get an error box, stating, that "compiler vendor SDCC version 3.6.0 #9615 not supported"!

gdb_error

I think, that some SDCC debug info tweaks needed to go next steps :( Also we may need to patch GDB to make it recognize SDCCs frame format...

Regards!

I'm not familiar with the SDCC / GDB /STVD integration issues, as I mostly just work on SDCC. However, others might be able to help:

Peter Dons Tychsen (SourceForge username donpedro2). He worked on STVD integration and provided SDCC patches to make the SDCC DWARF info in ELF output suitable for STVD integration.
Åke Rehnman (SourceForge username arehnman). He works porting the STM8 support in GDB to a current GDB version (https://sourceforge.net/projects/stm8-binutils-gdb/).

Can I find them on SDCC ML?

spth commented 7 years ago

Probably yes, but I'm not sure.

However, from Peter Dons Tychsen:

You can still use STVD if you hack the compiler ID in SDCC to be a known compiler.

P.S.: There are still some issues with the DWARF debug info for stm8 in SDCC 3.6.0, in particular, there are some problems with the debug info for: On-stack variables, bool variables, long long variables. Some of the issues are already fixed in current svn, the others will probably be fixed soon.
