|

* Pascal calling convention, 'type' is one of 'regs', 'word' or

|

* For register functions, the arguments are ignored, but they are still
|
|
* removed from the stack upon return.

*
|
|
* A special variant of the callback function is generated by the function
|

* profile "t_long_". This is used by the Win95 16->32 thunk
|
|
* functions C16ThkSL and C16ThkSL01 and is implemented as follows:
|
|
* On entry, the EBX register is set up to contain a flat pointer to the

|
* 16-bit stack such that EBX+22 points to the first argument.
|
|
* Then, the entry point is called, while EBP is set up to point
|
|
* to the return address (on the 32-bit stack).
|
|
* The called function returns with CX set to the number of bytes
|
|
* to be popped of the caller's stack.
|
|
*
|
|
* Stack layout upon entry to the callback function:
|
|
* ... ...
|
|
* (sp+18) word first 16-bit arg
|
|
* (sp+16) word cs
|
|
* (sp+14) word ip
|
|
* (sp+12) word bp
|
|
* (sp+8) long 32-bit entry point (used to store edx)
|
|
* (sp+6) word high word of cs (always 0, used to store es)
|
|
* (sp+4) word low word of cs of 16-bit entry point
|
|
* (sp+2) word high word of ip (always 0, used to store ds)
|
|
* (sp) word low word of ip of 16-bit entry point
|
|
*
|
|
* Added on the stack:
|
|
* (sp-2) word saved fs
|
|
* (sp-4) word buffer for Win16Mutex recursion count
|
|
* (sp-8) long ebp

|
|
* BuildCallTo32CBClient
|
|
*
|
|
* Call a CBClient relay stub from 32-bit code (KERNEL.620).
|
|
*
|
|
* Since the relay stub is itself 32-bit, this should not be a problem;
|
|
* unfortunately, the relay stubs are expected to switch back to a
|
|
* 16-bit stack (and 16-bit code) after completion :-(
|
|
*
|
|
* This would conflict with our 16- vs. 32-bit stack handling, so
|
|
* we simply switch *back* to our 32-bit stack before returning to
|
|
* the caller ...
|
|
*
|
|
* The CBClient relay stub expects to be called with:
|
|
* - ebp pointing to the 16-bit stack at ss:bp
|
|
* - ebx pointing to a buffer containing the saved 16-bit ss:sp
|
|
*
|
|
* After completion, the stub will load ss:sp from the buffer at ebx
|
|
* and perform a far return to 16-bit code.
|
|
*
|
|
* To trick the relay stub into returning to us, we push a 16-bit
|
|
* cs:ip pair pointing to out return entry point onto the 16-bit stack,
|
|
* followed by a ss:sp pair pointing to *that* cs:ip pair.
|
|
* Our return stub thus called will then reload the 32-bit ss:esp and
|
|
* return to 32-bit code (by using and ss:esp value that we have also
|
|
* pushed onto the 16-bit stack before and a cs:eip values found at
|
|
* that position on the 32-bit stack). The layout of our
|
|
* temporary area used on the 16-bit stack is thus as follows:
|
|
*
|
|
* (ebx+12) 32-bit ss (flat)
|
|
* (ebx+8) 32-bit sp (32-bit stack pointer)
|
|
* (ebx+6) 16-bit cs (this segment)
|
|
* (ebx+4) 16-bit ip ('16-bit' return entry point)
|
|
* (ebx+2) 16-bit ss (16-bit stack segment)
|
|
* (ebx+0) 16-bit sp (points to ebx+4)
|
|
*
|
|
* The stack layout of this function:
|
|
* (ebp+12) arg ebp value to be set for relay stub
|
|
* (ebp+8) func CBClient relay stub address
|
|
* (ebp+4) ret addr
|
|
* (ebp) ebp
