[llvm-dev] LLVM PDB Support

[Meena Jain via llvm-dev]

Dear Matt,

Thank you so much for providing me these details. 

These seems to be very helpful and enough to start with.

Between, I have a query in general,

I read somewhere that Microsoft linker generates the PDB file.

We have a proprietary compiler which generates windows compatible object code. We are using Microsoft linker only to generate the executable. Though we are able to generate PDB file using the linker /debug option but since it does not contain source information, we are not able to do the source level debugging. However, we are able to do assembly level debugging.

My doubt is, what role compiler plays which helps Microsoft linker to generate the PDB file with source level debugging information.

Thanks and Regards
Meena

I've made my resources on these topics publicly available -- perhaps they can be of some use or help:

Executable and object file formats (ELF, Mach-O, PE: EXE & DLL); debugging data formats (DWARF, PDB): articles, documentation, software, and talks.

In particular, here's the section on PDB:

Best regards,

Matt
