-** 29K COFF Declarations **
-** **
-** **
-** This file contains the declarations required to define **
-** the COFF format as proposed for use by AMD for the 29K **
-** family of RISC microprocessors. **
-** **
-** No attempt is made here to describe in detail those portions **
-** of COFF which have not been modified or extended. Pertinent **
-** #define's and struct's are included for completeness. Those **
-** declarations are distributed in several System V headers. **
-** **
-** For a better and more complete description of COFF with **
-** general and 29K Family specific clarifications, see the **
-** AMD's "Programmer's Guide to the Common Object File Format **
-** (COFF) for the Am29000" Application Note, order number 11963.**
-** **
-** For non-29K-Family specific COFF information, consult AT&T **
-** UNIX System V Release 3, Programmer's Guide, Chapter 11 **
-** (Manual 307-225, Issue 1). **
-** **
-** **
-** Revision history: **
-** **
-** 0.01 JG - first published **
-** 0.02 JG - added relocation type R_IFAR and renumbered **
-** 0.03 RC - COFF spec now compiles without error **
-** 0.04 RC - removed R_IPAIR and R_IFAR and renumbered **
-** 0.05 RC - added R_HWORD relocation type **
-** 0.06 RC - section types **
-** changed value of STYP_BSSREG **
-** replaced STYP_RDATA and STYP_IDATA **
-** with STYP_LIT, STYP_ABS, and STYP_ENVIR **
-** - relocation types **
-** added R_IABS **
-** replaced R_IBYTE with R_BYTE and renumbered **
-** - changed comments and removed comments **
-** 0.07 RC - relocation types **
-** Added R_IHCONST to support relocation offsets **
-** for CONSTH instruction. Added commentary, **
-** and renumbered to make room for R_IHCONST, **
-** putting the (as yet unused) global reloc **
-** types at the end. **
-** - bug fix (typo) **
-** Added slash to terminate comment field on **
-** C_EXT so now C_STAT is defined. **
-** 0.08 RC - official magic numbers assigned by AT&T. **
-** 0.09 RC - support multiple address spaces by adding magic **
-** a.out header numbers SASMAGIC and MASMAGIC. **
-** 0.10 RC - No changes. Just added the comments below and **
-** corrected comments on tsize, dsize, and bsize. **
-** - All portions of the COFF file described as C **
-** structs must use Host Endian byte ordering. **
-** Files created on a machine with a byte **
-** ordering different from the host may be **
-** converted using the UNIX conv(1) command. **
-** - Assemblers and compilers must create section **
-** headers for .text, .data, and .bss (in that **
-** order) even if they are 0 length. **
-** - tsize, dsize, and bsize are the size of .text, **
-** .data, and .bss respectively. Other sections **
-** of type STYP_TEXT, STYP_DATA, and STYP_BSS **
-** are not included in the byte count. **
-** - Assemblers and compilers must create output **
-** sections to the exact byte length (and not **
-** round them up). The linker will take care **
-** of rounding. **
-** 2.1.01 - Added C_STARTOF storage class for support of **
-** assembler $startof(sect_name) and **
-** $sizeof(sect_name) operators. **
-** 2.1.02 - Added a few more defines for completeness. **
-** 2.1.03 - Added more magic numbers for completeness. **
