Split the build program in several files. Renamed it 'winebuild' to avoid possible conflicts. Cleaned up command-line parsing. Make it understand -fPIC instead of -pic. Merged call16.s and call32.s generated files.

Specific ordinal +declarations are optional, but the default handler will print an error +message. + +"mode" specifies whether it is the spec file for a dll or the main exe. +This is only valid for Win32 spec files. + +"heap" is the size of the module local heap (only valid for Win16 +modules); default is no local heap. + +"file" gives the name of the Windows file that is replaced by the +builtin. <name>.DLL is assumed if none is given. (This is important +for kernel, which lives in the Windows file KRNL386.EXE). + +"init" specifies a function which will be called when this dll +is loaded. This is only valid for Win32 modules. + +"import" names a module that this one depends on (only for Win32 +modules at the present). The import declaration can be present several +times. + +"rsrc" specifies the prefix for the resource directory name. + +Lines whose first character is a '#' will be ignored as comments. + + +Variable ordinals: +================== + + This type defines data storage at the ordinal specified. You may +store items as bytes, 16-bit words, or 32-bit words. + "ORDINAL" is replaced by the ordinal number corresponding to the +variable. "VARTYPE" should be "byte", "word" or "long" for 8, 16, or +32 bits respectively. "EXPORTNAME" will be the name available for +dynamic linking. "DATA" can be a decimal number or a hex number preceeded +by "0x". The following example defines the variable "VariableA" at +ordinal 2 and containing 4 bytes: + + 2 byte VariableA(-1 0xff 0 0) + +Function ordinals: +================== + + This type defines a function entry point. The prototype defined by +"EXPORTNAME ([ARGTYPE [ARGTYPE [...]]])" specifies the name available for +dynamic linking and the format of the arguments. "ORDINAL" is replaced +by the ordinal number corresponding to the function, or "@" for +automatic ordinal allocation (Win32 only). + +"FUNCTYPE" should be one of: +- "pascal16" for a Win16 function returning a 16-bit value +- "pascal" for a Win16 function returning a 32-bit value +- "register" for a function using CPU register to pass arguments +- "interrupt" for a Win16 interrupt handler routine +- "stdcall" for a normal Win32 function +- "cdecl" for a Win32 function using the C calling convention +- "varargs" for a Win32 function taking a variable number of arguments + +"ARGTYPE" should be one of: +- "word" +- "long" +- "ptr" (linear pointer) +- "str" (linear pointer to a null-terminated string) +- "s_word" (signed word) +- "segptr" (segmented pointer). +- "segstr" (segmented pointer to a null-terminated string) + +Only "ptr", "str" and "long" are valid for Win32 functions. + +"HANDLERNAME" is the name of the actual Wine function that will +process the request in 32-bit mode. + + This first example defines an entry point for the CreateWindow() +call (the ordinal 100 is just an example): + + 100 pascal CreateWindow(ptr ptr long s_word s_word s_word s_word + word word word ptr) + WIN_CreateWindow + + This second example defines an entry point for the GetFocus() +call (the ordinal 100 is just an example): + + 100 pascal GetFocus() WIN_GetFocus() + +To declare a function using a variable number of arguments in Win16, +specify the function as taking no arguments. The arguments are then +available with CURRENT_STACK16->args. In Win32, specify the function +as 'varargs' and declare it with a '...' parameter in the C file. See +the wsprintf* functions in user.spec and user32.spec for an example. + +Stub ordinals: +============== + + This type defines a stub function. It makes the name and ordinal +available for dynamic linking, but will terminate execution with an +error message if the function is ever called. + +Equate ordinals: +================ + + This type defines an ordinal as an absolute value. +"ORDINAL" is replaced by the ordinal number corresponding to the +variable. "EXPORTNAME" will be the name available for dynamic linking. +"DATA" can be a decimal number or a hex number preceeded by "0x". + +Extern ordinals: +================ + + This type defines an entry that simply maps to a Wine symbol +(variable or function); "EXPORTNAME" will point to the symbol +"SYMBOLNAME" that must be defined in C code. This type only works with +Win32. + +Forwarded ordinals: +=================== + + This type defines an entry that is forwarded to another entry +point (kind of a symbolic link). "EXPORTNAME" will forward to the +entry point "SYMBOLNAME" that must be of the form "DLL.Function". This +type only works with Win32. +

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?

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, 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.
