* seeing the binary in glTF .glb files at the same time as the .glTF I assume by “seeing… the glTF” you mean seeing the objects in a 3D scene, more or less rendered in their polygonal glory. Doesn’t sound like a good fit for DWARF. DWARF was designed to facilitate debugging of comp

[Dwarf-discuss] Aranges address entry alignment?

2024-07-13 Thread Vsevolod Alekseyev via Dwarf-discuss
In DWARF v3, section 7.20 deals with the structure of the debug_aranges section. Near the end, there is the following paragraph: "This header is followed by a series of tuples. Each tuple consists of an address and a length, each in the size appropriate for an address on the target architecture

[Dwarf-discuss] Expression opcode 0xD0

2024-04-07 Thread Vsevolod Alekseyev via Dwarf-discuss
Hi all, I've got a crash report that my DWARF expression parser crashed on the following expression blob: 09 03 D0 39 8C That looks like DW_OP_const1s with 3 as the argument, followed by a bogus opcode D0. It's not a valid opcode and not in the user extension area. Anyone ever encounter

Please help me interpret the DWARF spec regarding the DW_AT_frame_base. Quoted by spec v3, section 3.5.5, but similar wording in v4 and v5: "A subroutine or entry point entry may also have a DW_AT_frame_base attribute, whose value is a location description that computes the "frame base" for the

Greetings, I'm involved with a Python DWARF parser, Pyelftools ( https://github.com/eliben/pyelftools/ ). I have a question about DWARF5 and the newly indexed loclists/rnglists sections, please. In those sections, each CU gets a block. The block starts with a header, which starts with a 4/1
