1044	* From TIS:
1045	* Type = 4bit fixup type. This value has the following definitions:
1046	* 0h Absolute. This is a NOP. The fixup is skipped.
1047	* 1h High. Add the high 16 bits of the delta to the 16 bit field at Offset.
1048	* The 16bit field represents the high value of a 32 bit word.
1049	* 2h Low. Add the low 16 bits of the delta to the 16 bit field at Offset.
1050	* The 16 bit field represents the low half value of a 32 bit word. This
1051	* fixup will only be emitted for a RISC machine when the image Object
1052	* Align isn't the default of 64K.
1053	* 3h Highlow. Apply the 32 bit delta to the 32 bit field at Offset.
1054	* 4h Highadjust. This fixup requires a full 32 bit value. The high 16 bits
1055	* is located at Offset, and the low 16 bits is located in the next Offset
1056	* array element (this array element is included in the Size field). The

2479	* Object Table
2480	*
2481	* VIRTUAL SIZE = DD Virtual memory size. This is the size of the object that will be
2482	* allocated when the object is loaded. The object data length must be less than or equal
2483	* to the total size of the pages in the EXE file for the object. This memory size must also
2484	* be large enough to contain all of the iterated data and uninitialized data in the EXE file.
2485	*
2486	* RELOC BASE ADDR = DD Relocation Base Address. The relocation base address the object is
2487	* currently relocated to. If the internal relocation fixups for the module have been removed,
2488	* this is the address the object will be allocated at by the loader.
2489	*
2490	* OBJECT FLAGS = DW Flag bits for the object. The object flag bits have the following definitions.
2491	*
2492	* 0001h = Readable Object.
2493	* 0002h = Writable Object.
2494	* 0004h = Executable Object. The readable, writable and executable flags provide support
2495	* for all possible protections. In systems where all of these protections are not
2496	* supported, the loader will be responsible for making the appropriate protection match
2497	* for the system.
2498	*
2499	* 0008h = Resource Object.
2500	* 0010h = Discardable Object.
2501	* 0020h = Object is Shared.
2502	* 0040h = Object has Preload Pages.
2503	* 0080h = Object has Invalid Pages.
2504	* 0100h = Object has Zero Filled Pages.
2505	* 0200h = Object is Resident (valid for VDDs, PDDs only).
2506	* 0300h = Object is Resident Contiguous (VDDs, PDDs only).
2507	* 0400h = Object is Resident 'long-lockable' (VDDs, PDDs only).
2508	* 0800h = Reserved for system use.
2509	* 1000h = 16
2510	* 2000h = Big/Default Bit Setting (80x86 Specific). The 'big/default' bit , for data
2511	* segments, controls the setting of the Big bit in the segment descriptor. (The Big
2512	* bit, or B-bit, determines whether ESP or SP is used as the stack pointer.) For code
2513	* segments, this bit controls the setting of the Default bit in the segment descriptor.
2514	* (The Default bit, or D-bit, determines whether the default word size is 32-bits or
2515	* 16-bits. It also affects the interpretation of the instruction stream.)
2516	*
2517	* 4000h = Object is conforming for code (80x86 Specific).
2518	* 8000h = Object I/O privilege level (80x86 Specific). Only used for 16
2519	*
2520	* PAGE TABLE INDEX = DD Object Page Table Index. This specifies the number of the first
2521	* object page table entry for this object. The object page table specifies where in the EXE
2522	* file a page can be found for a given object and specifies per-page attributes. The object
2523	* table entries are ordered by logical page in the object table. In other words the object
2524	* table entries are sorted based on the object page table index value.
2525	*
2526	* # PAGE TABLE ENTRIES = DD # of object page table entries for this object. Any logical
2527	* pages at the end of an object that do not have an entry in the object page table associated
2528	* with them are handled as zero filled or invalid pages by the loader. When the last logical
2529	* pages of an object are not specified with an object page table entry, they are treated as
2530	* either zero filled pages or invalid pages based on the last entry in the object page table
2531	* for that object. If the last entry was neither a zero filled or invalid page, then the
2532	* additional pages are treated as zero filled pages.
2533	*
2534	* RESERVED = DD Reserved for future use. Must be set to zero.
2535	*

2603	*
2604	* The Object page table provides information about a logical page in an object. A logical page
2605	* may be an enumerated page, a pseudo page or an iterated page. The structure of the object
2606	* page table in conjunction with the structure of the object table allows for efficient access
2607	* of a page when a page fault occurs, while still allowing the physical page data to be
2608	* located in the preload page, demand load page or iterated data page sections in the linear
2609	* EXE module. The logical page entries in the Object Page Table are numbered starting from one.
2610	* The Object Page Table is parallel to the Fixup Page Table as they are both indexed by the
2611	* logical page number. Each Object Page Table entry has the following format:
2612	*
2613	* 63 32 31 16 15 0

2618	* Object Page Table Entry
2619	*
2620	* PAGE DATA OFFSET = DD Offset to the page data in the EXE file. This field, when bit
2621	* shifted left by the PAGE OFFSET SHIFT from the module header, specifies the offset from
2622	* the beginning of the Preload Page section of the physical page data in the EXE file that
2623	* corresponds to this logical page entry. The page data may reside in the Preload Pages,
2624	* Demand Load Pages or the Iterated Data Pages sections. A page might not start at the next
2625	* available alignment boundary. Extra padding is acceptable between pages as long as each
2626	* page starts on an alignment boundary. For example, several alignment boundarys may be
2627	* skipped in order to start a frequently accessed page on a sector boundary. If the FLAGS
2628	* field specifies that this is a Zero-Filled page then the PAGE DATA OFFSET field will
2629	* contain a 0. If the logical page is specified as an iterated data page, as indicated by
2630	* the FLAGS field, then this field specifies the offset into the Iterated Data Pages section.
2631	* The logical page number (Object Page Table index), is used to index the Fixup Page Table to
2632	* find any fixups associated with the logical page.
2633	*
2634	* DATA SIZE = DW Number of bytes of data for this page. This field specifies the actual
2635	* number of bytes that represent the page in the file. If the PAGE SIZE field from the
2636	* module header is greater than the value of this field and the FLAGS field indicates a Legal
2637	* Physical Page, the remaining bytes are to be filled with zeros. If the FLAGS field
2638	* indicates an Iterated Data Page, the iterated data records will completely fill out the
2639	* remainder.

4455	* contains the module name. These tables are used to translate a procedure name string into
4456	* an ordinal number by searching for a matching name string. The ordinal number is used to
4457	* locate the entry point information in the entry table. The resident name table is kept
4458	* resident in system memory while the module is loaded. It is intended to contain the

4764	*
4765	* RESERVED = DW 0 This field is reserved for future use.
4766	*
4767	* FLAGS = DB Forwarder flags. These are the flags for this entry point. They have the
4768	* following definition.
4769	* 01h = Import by ordinal.
4770	* F7h = Reserved for future use; should be zero.
4771	*
4772	* MOD ORD# = DW Module Ordinal Number This is the index into the Import Module Name Table
4773	* for this forwarder.
4774	*
4775	* OFFSET / ORDNUM = DD Procedure Name Offset or Import Ordinal Number If the FLAGS field
4776	* indicates import by ordinal, then this field is the ordinal number into the Entry Table
4777	* of the target module, otherwise this field is the offset into the Procedure Names Table
4778	* of the (?)target(?) module.
4779	*
4780	* A Forwarder entry (type = 4) is an entry point whose value is an imported reference. When a
4781	* load time fixup occurs whose target is a forwarder, the loader obtains the address imported
4782	* by the forwarder and uses that imported address to resolve the fixup.
4783	*
4784	* A forwarder may refer to an entry point in another module which is itself a forwarder, so there
4785	* can be a chain of forwarders. The loader will traverse the chain until it finds a non-forwarded
4786	* entry point which terminates the chain , and use this to resolve the original fixup. Circular
4787	* chains are detected by the loader and result in a load time error. A maximum of 1024
4788	* forwarders is allowed in a chain; more than this results in a load time error.
4789	*
4790	* Forwarders are useful for merging and recombining API calls into different sets of libraries,
4791	* while maintaining compatibility with applications. For example, if one wanted to combine
4792	* MONCALLS, MOUCALLS, and VIOCALLS into a single libraries, one could provide entry points
4793	* for the three libraries that are forwarders pointing to the common implementation.
4794	*
4795	* ---------------
4796	*
4797	* Forwarder makes some minor difficulties concerning function names.
4798	* We then have to
4799	* 1) Allways convert entries before imports (fixups).
4800	* 2) When forwarders are present makeFixups can't be called without calling makeExports first.
4801	* 3) initEntries will clean up import variables too if fForwarders is set.
