1725 * 'T'=segmented pointer to null-terminated string).
1727 * The generated routines fetch the arguments from the 16-bit stack (pointed

1729 * according to the calling convention and the argument types. Then, the
1730 * 32-bit entry point is called with these arguments.
1732 * For register functions, the arguments (if present) are converted just
1733 * the same as for normal functions, but in addition the CONTEXT86 pointer
1734 * filled with the current register values is passed to the 32-bit routine.
1735 * (An 'intr' interrupt handler routine is treated exactly like a register
1736 * routine, except that upon return, the flags word pushed onto the stack
1737 * by the interrupt is removed by the 16-bit call stub.)

1924 * This routine builds the core routines used in 16->32 thunks:
1925 * CallFrom16Word, CallFrom16Long, CallFrom16Register, and CallFrom16Thunk.
1927 * These routines are intended to be called via a far call (with 32-bit
1928 * operand size) from 16-bit code. The 16-bit code stub must push %bp,
1929 * the 32-bit entry point to be called, and the argument conversion
1930 * routine to be used (see stack layout below).
1932 * The core routine completes the STACK16FRAME on the 16-bit stack and
1933 * switches to the 32-bit stack. Then, the argument conversion routine
1934 * is called; it gets passed the 32-bit entry point and a pointer to the
1935 * 16-bit arguments (on the 16-bit stack) as parameters. (You can either
1936 * use conversion routines automatically generated by BuildCallFrom16,
1937 * or write your own for special purposes.)
1939 * The conversion routine must call the 32-bit entry point, passing it
1940 * the converted arguments, and return its return value to the core.
1941 * After the conversion routine has returned, the core switches back
1942 * to the 16-bit stack, converts the return value to the DX:AX format
1943 * (CallFrom16Long), and returns to the 16-bit call stub. All parameters,
1944 * including %bp, are popped off the stack.
1946 * The 16-bit call stub now returns to the caller, popping the 16-bit
1947 * arguments if necessary (pascal calling convention).
1949 * In the case of a 'register' function, CallFrom16Register fills a
1950 * CONTEXT86 structure with the values all registers had at the point
1951 * the first instruction of the 16-bit call stub was about to be
1952 * executed. A pointer to this CONTEXT86 is passed as third parameter
1953 * to the argument conversion routine, which typically passes it on
1954 * to the called 32-bit entry point.
1956 * CallFrom16Thunk is a special variant used by the implementation of
1957 * the Win95 16->32 thunk functions C16ThkSL and C16ThkSL01 and is
1958 * implemented as follows:
1959 * On entry, the EBX register is set up to contain a flat pointer to the
1960 * 16-bit stack such that EBX+22 points to the first argument.
1961 * Then, the entry point is called, while EBP is set up to point
1962 * to the return address (on the 32-bit stack).
1963 * The called function returns with CX set to the number of bytes
1964 * to be popped of the caller's stack.
1966 * Stack layout upon entry to the core routine (STACK16FRAME):
1968 * (sp+24) word first 16-bit arg
1972 * (sp+14) long 32-bit entry point (reused for Win16 mutex recursion count)
1973 * (sp+12) word ip of actual entry point (necessary for relay debugging)
1974 * (sp+8) long relay (argument conversion) function entry point
1975 * (sp+4) long cs of 16-bit entry point
1976 * (sp) long ip of 16-bit entry point
1978 * Added on the stack:
1979 * (sp-2) word saved gs
1980 * (sp-4) word saved fs
1981 * (sp-6) word saved es
1982 * (sp-8) word saved ds

2593 * BuildCallTo32CBClient
2595 * Call a CBClient relay stub from 32-bit code (KERNEL.620).
2597 * Since the relay stub is itself 32-bit, this should not be a problem;
2598 * unfortunately, the relay stubs are expected to switch back to a
2599 * 16-bit stack (and 16-bit code) after completion :-(
2601 * This would conflict with our 16- vs. 32-bit stack handling, so
2602 * we simply switch *back* to our 32-bit stack before returning to
2605 * The CBClient relay stub expects to be called with the following
2606 * 16-bit stack layout, and with ebp and ebx pointing into the 16-bit
2607 * stack at the designated places:
2610 * (ebp+14) original arguments to the callback routine
2611 * (ebp+10) far return address to original caller
2612 * (ebp+6) Thunklet target address
2613 * (ebp+2) Thunklet relay ID code
2614 * (ebp) BP (saved by CBClientGlueSL)
2615 * (ebp-2) SI (saved by CBClientGlueSL)
2616 * (ebp-4) DI (saved by CBClientGlueSL)
2617 * (ebp-6) DS (saved by CBClientGlueSL)
2619 * ... buffer space used by the 16-bit side glue for temp copies
2621 * (ebx+4) far return address to 16-bit side glue code
2622 * (ebx) saved 16-bit ss:sp (pointing to ebx+4)
2624 * The 32-bit side glue code accesses both the original arguments (via ebp)
2625 * and the temporary copies prepared by the 16-bit side glue (via ebx).
2626 * After completion, the stub will load ss:sp from the buffer at ebx
2627 * and perform a far return to 16-bit code.
2629 * To trick the relay stub into returning to us, we replace the 16-bit
2630 * return address to the glue code by a cs:ip pair pointing to our
2631 * return entry point (the original return address is saved first).
2632 * Our return stub thus called will then reload the 32-bit ss:esp and
2633 * return to 32-bit code (by using and ss:esp value that we have also
2634 * pushed onto the 16-bit stack before and a cs:eip values found at
2635 * that position on the 32-bit stack). The ss:esp to be restored is
2636 * found relative to the 16-bit stack pointer at:
2639 * (ebx-8) sp (32-bit stack pointer)
2641 * The second variant of this routine, CALL32_CBClientEx, which is used
2642 * to implement KERNEL.621, has to cope with yet another problem: Here,
2643 * the 32-bit side directly returns to the caller of the CBClient thunklet,
2644 * restoring registers saved by CBClientGlueSL and cleaning up the stack.
2645 * As we have to return to our 32-bit code first, we have to adapt the
2646 * layout of our temporary area so as to include values for the registers
2647 * that are to be restored, and later (in the implementation of KERNEL.621)
2648 * we *really* restore them. The return stub restores DS, DI, SI, and BP
2649 * from the stack, skips the next 8 bytes (CBClient relay code / target),
2650 * and then performs a lret NN, where NN is the number of arguments to be
2651 * removed. Thus, we prepare our temporary area as follows:
2653 * (ebx+22) 16-bit cs (this segment)
2654 * (ebx+20) 16-bit ip ('16-bit' return entry point)
2655 * (ebx+16) 32-bit ss (flat)
2656 * (ebx+12) 32-bit sp (32-bit stack pointer)
2657 * (ebx+10) 16-bit bp (points to ebx+24)
2658 * (ebx+8) 16-bit si (ignored)
2659 * (ebx+6) 16-bit di (ignored)
2660 * (ebx+4) 16-bit ds (we actually use the flat DS here)
2661 * (ebx+2) 16-bit ss (16-bit stack segment)
2662 * (ebx+0) 16-bit sp (points to ebx+4)
2664 * Note that we ensure that DS is not changed and remains the flat segment,
2665 * and the 32-bit stack pointer our own return stub needs fits just
2666 * perfectly into the 8 bytes that are skipped by the Windows stub.
2667 * One problem is that we have to determine the number of removed arguments,
2668 * as these have to be really removed in KERNEL.621. Thus, the BP value
2669 * that we place in the temporary area to be restored, contains the value
2670 * that SP would have if no arguments were removed. By comparing the actual
2671 * value of SP with this value in our return stub we can compute the number
2672 * of removed arguments. This is then returned to KERNEL.621.
2674 * The stack layout of this function:
2675 * (ebp+20) nArgs pointer to variable receiving nr. of args (Ex only)
2676 * (ebp+16) esi pointer to caller's esi value
2677 * (ebp+12) arg ebp value to be set for relay stub
2678 * (ebp+8) func CBClient relay stub address
