I would like to request the assignment of a DW_LANG_ constant for the Netwide Assembler (NASM). Currently we are using 0x8001, DW_LANG_lo_user+1, which is documented in most tools as DW_LANG_Mips_Assember. This is clearly bogus, and fails to distinguish NASM from other kinds of assemblers.

Rather than "squatting" on a user code, having one officially assigned is always preferable.

The Netwide Assembler can be found at, and is widely used.

Many thanks.

2023-04-11: Accepted with modifications. We will allocate a language code for general assembly language code, but not for a specific assembler. Also added a DWARF v6 language name.

2023-04-19: New language codes (for v5 and v6):

DW_LANG_Assembly     0x0031
DW_LNAME_Assembly    0x001d
