I can't help it, but it is our company name. Well, it used to be.
Tasking is now part of Altium. Tasking is still the product
name of the embedded tools that we have. We have been making
compilers and other tools for embedded software for about 20
years now. Maybe you want to have a look at http://www.tasking.com/
I know the word is confusing, and with a little irony I said
that I can't help it. We have been using these names for several
years now, and we've communicated them with some third party vendors.
Now, if everybody immediately connected the name "Tasking" with
embedded tools it would have been a different story.
It's OK with me if we change them to Altium names. And now with comments
as we have them in our dwarf.h. Ignore the fact that we have them as enums.
DW_TAG_ALTIUM_circ_type = 0x5101, /* ALTIUM DSP-C/Starcore __circ qualifier */
DW_TAG_ALTIUM_mwa_circ_type = 0x5102, /* ALTIUM Starcore __mwa_circ qualifier */
DW_TAG_ALTIUM_rev_carry_type = 0x5103, /* ALTIUM Starcore __rev_carry qualifier */
DW_TAG_ALTIUM_rom = 0x5111, /* ALTIUM M16 __rom qualifier */
DW_ATE_ALTIUM_fract = 0x80, /* ALTIUM __fract type */
DW_ATE_ALTIUM_accum = 0x81, /* ALTIUM __accum type */
DW_LANG_ALTIUM_Assembler = 0x9101,
DW_CC_ALTIUM_interrupt = 0x65, /* Function is an interrupt handler, return address on system stack */
DW_CC_ALTIUM_near_system_stack = 0x66, /* Near function model, return address on system stack */
DW_CC_ALTIUM_near_user_stack = 0x67, /* Near function model, return address on user stack */
DW_CC_ALTIUM_huge_user_stack = 0x68, /* Huge function model, return address on user stack */

It this the part that you refer to (section 7.1)?
"... conventionally use the form prefix_vendor_id_name, where vendor_id is some identifying
character sequence chosen so as to avoid conflicts with other vendors."
In that case there was nothing wrong with the original names, except that all other
vendor names are in allcaps.
Hope this clarifies it.
