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.

I try to make the dwarf.h  file complete in its set of DW_AT values,

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.
