Then, the argument conversion routine - * is called; it gets passed the 32-bit entry point and a pointer to the - * 16-bit arguments (on the 16-bit stack) as parameters. (You can either - * use conversion routines automatically generated by BuildCallFrom16, - * or write your own for special purposes.) - * - * The conversion routine must call the 32-bit entry point, passing it - * the converted arguments, and return its return value to the core. - * After the conversion routine has returned, the core switches back - * to the 16-bit stack, converts the return value to the DX:AX format - * (CallFrom16Long), and returns to the 16-bit call stub.

- * 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 the following - * 16-bit stack layout, and with ebp and ebx pointing into the 16-bit - * stack at the designated places: - * - * ... - * (ebp+14) original arguments to the callback routine - * (ebp+10) far return address to original caller - * (ebp+6) Thunklet target address - * (ebp+2) Thunklet relay ID code - * (ebp) BP (saved by CBClientGlueSL) - * (ebp-2) SI (saved by CBClientGlueSL) - * (ebp-4) DI (saved by CBClientGlueSL) - * (ebp-6) DS (saved by CBClientGlueSL) - * - * ... buffer space used by the 16-bit side glue for temp copies - * - * (ebx+4) far return address to 16-bit side glue code - * (ebx) saved 16-bit ss:sp (pointing to ebx+4) - * - * The 32-bit side glue code accesses both the original arguments (via ebp) - * and the temporary copies prepared by the 16-bit side glue (via ebx). - * 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 replace the 16-bit - * return address to the glue code by a cs:ip pair pointing to our - * return entry point (the original return address is saved first). - * 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 ss:esp to be restored is - * found relative to the 16-bit stack pointer at: - * - * (ebx-4) ss (flat) - * (ebx-8) sp (32-bit stack pointer) - * - * The second variant of this routine, CALL32_CBClientEx, which is used - * to implement KERNEL.621, has to cope with yet another problem: Here, - * the 32-bit side directly returns to the caller of the CBClient thunklet, - * restoring registers saved by CBClientGlueSL and cleaning up the stack. - * As we have to return to our 32-bit code first, we have to adapt the - * layout of our temporary area so as to include values for the registers - * that are to be restored, and later (in the implementation of KERNEL.621) - * we *really* restore them. The return stub restores DS, DI, SI, and BP - * from the stack, skips the next 8 bytes (CBClient relay code / target), - * and then performs a lret NN, where NN is the number of arguments to be - * removed. Thus, we prepare our temporary area as follows: - * - * (ebx+22) 16-bit cs (this segment) - * (ebx+20) 16-bit ip ('16-bit' return entry point) - * (ebx+16) 32-bit ss (flat) - * (ebx+12) 32-bit sp (32-bit stack pointer) - * (ebx+10) 16-bit bp (points to ebx+24) - * (ebx+8) 16-bit si (ignored) - * (ebx+6) 16-bit di (ignored) - * (ebx+4) 16-bit ds (we actually use the flat DS here) - * (ebx+2) 16-bit ss (16-bit stack segment) - * (ebx+0) 16-bit sp (points to ebx+4) - * - * Note that we ensure that DS is not changed and remains the flat segment, - * and the 32-bit stack pointer our own return stub needs fits just - * perfectly into the 8 bytes that are skipped by the Windows stub. - * One problem is that we have to determine the number of removed arguments, - * as these have to be really removed in KERNEL.621. Thus, the BP value - * that we place in the temporary area to be restored, contains the value - * that SP would have if no arguments were removed. By comparing the actual - * value of SP with this value in our return stub we can compute the number - * of removed arguments. This is then returned to KERNEL.621. - * - * The stack layout of this function: - * (ebp+20) nArgs pointer to variable receiving nr. of args (Ex only) - * (ebp+16) esi pointer to caller's esi value - * (ebp+12) arg ebp value to be set for relay stub - * (ebp+8) func CBClient relay stub address - * (ebp+4) ret addr - * (ebp) ebp - */ -static void BuildCallTo32CBClient( FILE *outfile, BOOL isEx ) -{ - char *name = isEx?

The 16-bit code stub must push %bp, + * the 32-bit entry point to be called, and the argument conversion + * routine to be used (see stack layout below). + * + * The core routine completes the STACK16FRAME on the 16-bit stack and + * switches to the 32-bit stack. Then, the argument conversion routine + * is called; it gets passed the 32-bit entry point and a pointer to the + * 16-bit arguments (on the 16-bit stack) as parameters. (You can either + * use conversion routines automatically generated by BuildCallFrom16, + * or write your own for special purposes.) + * + * The conversion routine must call the 32-bit entry point, passing it + * the converted arguments, and return its return value to the core. + * After the conversion routine has returned, the core switches back + * to the 16-bit stack, converts the return value to the DX:AX format + * (CallFrom16Long), and returns to the 16-bit call stub. All parameters, + * including %bp, are popped off the stack. + * + * The 16-bit call stub now returns to the caller, popping the 16-bit + * arguments if necessary (pascal calling convention). + * + * In the case of a 'register' function, CallFrom16Register fills a + * CONTEXT86 structure with the values all registers had at the point + * the first instruction of the 16-bit call stub was about to be + * executed. A pointer to this CONTEXT86 is passed as third parameter + * to the argument conversion routine, which typically passes it on + * to the called 32-bit entry point. + * + * CallFrom16Thunk is a special variant used by the implementation of + * 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 core routine (STACK16FRAME): + * ... ... + * (sp+24) word first 16-bit arg + * (sp+22) word cs + * (sp+20) word ip + * (sp+18) word bp + * (sp+14) long 32-bit entry point (reused for Win16 mutex recursion count) + * (sp+12) word ip of actual entry point (necessary for relay debugging) + * (sp+8) long relay (argument conversion) function entry point + * (sp+4) long cs of 16-bit entry point + * (sp) long ip of 16-bit entry point + * + * Added on the stack: + * (sp-2) word saved gs + * (sp-4) word saved fs + * (sp-6) word saved es + * (sp-8) word saved ds + * (sp-12) long saved ebp + * (sp-16) long saved ecx + * (sp-20) long saved edx + * (sp-24) long saved previous stack + */ +static void BuildCallFrom16Core( FILE *outfile, int reg_func, int thunk, int short_ret ) +{ + char *name = thunk?
