Re: [Dwarf-Discuss] DW_AT values unknown to me.

Green Hills has never contacted us about DWARF implementation or 
submitted any proposals to the DWARF Committee.


Many years ago, I was on an ABI committee with Greg Davis, who I believe 
is Director of Engineering at GHS.  You might contact him for 
information about these attributes.  The last email I have for him is 
gda...@ghs.com.

TotalView supported their compiler on the BBN Butterfly in the early '90s, but 
that predated DWARF support. Maybe someone at Green Hills can tell you what 
they mean.

If anyone can come up with the proper spellings and let me know
what those are I would appreciate it.

Thanks in advance.

Would you potentially be interested in contributing some of the missing vendor 
extensions to LLVM's DWARF parser 
(https://github.com/llvm/llvm-project/blob/main/llvm/include/llvm/BinaryFormat/Dwarf.def
 
)?
 
The "system" dwarfdump on several platforms is derived from that file and it 
would be neat to have it understand more unknown attributes and avoid future 
collisions in the vendor space.

[Dwarf-Discuss] DW_AT values unknown to me.

2021-02-17 Thread David Anderson via Dwarf-Discuss 

I try to make the dwarf.h  file complete in its set of DW_AT values,
including non-standard entries I know nothing about.

I recently came across a few whose proper spelling is
completely unknown to me. So I made up names.
Browser searches revealed nothing so far.

/*  From DWARF2 DW_AT_producer GHS C 2012.5.4 [dual] */
#define DW_AT_GHS_unknown1 0x2083
#define DW_AT_GHS_unknown2 0x2087
#define DW_AT_GHS_unknown3 0x2085
#define DW_AT_GHS_unknown4 0x2086
#define DW_AT_GHS_unknown5 0x2092

If anyone can come up with the proper spellings and let me know
what those are I would appreciate it.

Thanks in advance.
