前面介紹了分析腳本類的聲明，下面來仔細地分析它的實現代碼，理解它的實現過程，也就理解了腳本代碼的編譯過程，如下：

?

返回生成的代碼大小為 0.

#001 ? S32 LLScriptScript::getSize()

#002 ? {

#003 ? ?? return 0;

#004 ? }

#005 ?

?

腳本類的構造函數，主要進行初始化的工作。

#006 ? LLScriptScript::LLScriptScript(LLScritpGlobalStorage *globals,

#007 ? ?????????????????????????? ??? LLScriptState *states) :

#008 ????? LLScriptFilePosition(0, 0),

#009 ? ?? mStates(states), mGlobalScope(NULL), mGlobals(NULL), mGlobalFunctions(NULL), mGodLike(FALSE)

#010 ? {

?

設置缺省生成字節碼的文件名稱。

#011 ? ?? const char DEFAULT_BYTECODE_FILENAME[] = "lscript.lso";

#012 ? ?? strncpy(mBytecodeDest, DEFAULT_BYTECODE_FILENAME, sizeof(mBytecodeDest) -1); /*Flawfinder: ignore*/

#013 ? ?? mBytecodeDest[MAX_STRING-1] = '/0';

?

下面開始分析全局變量和全局函數的保存位置。

#014 ? ?? LLScriptGlobalVariable ? *tvar;

#015 ? ?? LLScriptGlobalFunctions *tfunc;

#016 ? ?? LLScritpGlobalStorage *temp;

#017 ?

#018 ? ?? temp = globals;

#019 ? ?? while(temp)

#020 ? ?? {

#021 ? ?????? if (temp->mbGlobalFunction)

#022 ? ?????? {

#023 ? ?????????? if (!mGlobalFunctions)

#024 ? ?????????? {

#025 ? ?????????????? mGlobalFunctions = (LLScriptGlobalFunctions *)temp->mGlobal;

#026 ? ?????????? }

#027 ? ?????????? else

#028 ? ?????????? {

#029 ? ?????????????? tfunc = mGlobalFunctions;

#030 ? ?????????????? while(tfunc->mNextp)

#031 ? ?????????????? {

#032 ? ?????????????????? tfunc = tfunc->mNextp;

#033 ? ?????????????? }

#034 ? ?????????????? tfunc->mNextp = (LLScriptGlobalFunctions *)temp->mGlobal;

#035 ? ?????????? }

#036 ? ?????? }

#037 ? ?????? else

#038 ? ?????? {

#039 ? ?????????? if (!mGlobals)

#040 ? ?????????? {

#041 ? ?????????????? mGlobals = (LLScriptGlobalVariable *)temp->mGlobal;

#042 ? ?????????? }

#043 ? ?????????? else

#044 ? ?????????? {

#045 ? ?????????????? tvar = mGlobals;

#046 ? ?????????????? while(tvar->mNextp)

#047 ? ?????????????? {

#048 ? ?????????????????? tvar = tvar->mNextp;

#049 ? ?????????????? }

#050 ? ?????????????? tvar->mNextp = (LLScriptGlobalVariable *)temp->mGlobal;

#051 ? ?????????? }

#052 ? ?????? }

#053 ? ?????? temp = temp->mNextp;

#054 ? ?? }

#055 ? }

#056 ?

?

這個函數主要實現設置字節碼保存的文件名稱。

#057 ? void LLScriptScript::setBytecodeDest(const char* dst_filename)

#058 ? {

#059 ? ?? strncpy(mBytecodeDest, dst_filename, MAX_STRING); ? /*Flawfinder: ignore*/

#060 ? ?? mBytecodeDest[MAX_STRING-1] = '/0';

#061 ? }

#062 ?

?

#063 ? void print_cil_globals(FILE* fp, LLScriptGlobalVariable* global)

#064 ? {

#065 ? ?? fprintf(fp, ".field private ");

#066 ? ?? print_cil_type(fp, global->mType->mType);

#067 ? ?? fprintf(fp, " ");

#068 ? ?? fprintf(fp, global->mIdentifier->mName); ??????? /*Flawfinder: ignore*/

#069 ? ?? fprintf(fp, "/n");

#070 ? ?? if(NULL != global->mNextp)

#071 ? ?? {

#072 ? ?????? print_cil_globals(fp, global->mNextp);

#073 ? ?? }

#074 ? }

#075

?

開始遞歸處理所有腳本樹。

#076 ? void LLScriptScript::recurse(FILE *fp, S32 tabs, S32 tabsize, LSCRIPTCompilePass pass, LSCRIPTPruneType ptype, BOOL &prunearg, LLScriptScope *scope, LSCRIPTType &type,

#077 ? LSCRIPTType basetype, U64 &count, LLScriptByteCodeChunk *chunk, LLScriptByteCodeChunk *heap, S32 stacksize, LLScriptScopeEntry *entry, S32 entrycount, LLScriptLibData **ldata)

#078 ? {

?

如果分析有出錯，就不再處理。

#079 ? ?? if (gErrorToText.getErrors())

#080 ? ?? {

#081 ? ?????? return;

#082 ? ?? }

?

根據不同的編譯遍來作不同的樹遍歷處理。

#083 ? ?? switch(pass)

#084 ? ?? {

?

輸出合適的說明文字。

#085 ? ?? case LSCP_PRETTY_PRINT:

#086 ? ?????? if (mGlobals)

#087 ? ?????? {

#088 ? ?????????? fdotabs(fp, tabs, tabsize);

#089 ? ?????????? mGlobals->recurse(fp, tabs, tabsize, pass, ptype, prunearg, scope, type, basetype, count, chunk, heap, stacksize, entry, entrycount,

#090 ? NULL);

#091 ? ?????? }

#092 ?

#093 ? ?????? if (mGlobalFunctions)

#094 ? ?????? {

#095 ? ?????????? fdotabs(fp, tabs, tabsize);

#096 ? ?????????? mGlobalFunctions->recurse(fp, tabs, tabsize, pass, ptype, prunearg, scope, type, basetype, count, chunk, heap, stacksize, entry,

#097 ? entrycount, NULL);

#098 ? ?????? }

#099 ?

#100 ? ?????? fdotabs(fp, tabs, tabsize);

#101 ? ?????? mStates->recurse(fp, tabs, tabsize, pass, ptype, prunearg, scope, type, basetype, count, chunk, heap, stacksize, entry, entrycount, NULL);

#102 ? ?????? break;

?

進行代碼優化，主要刪除不需要的代碼。

#103 ? ?? case LSCP_PRUNE:

#104 ? ?????? if (mGlobalFunctions)

#105 ? ?????? {

#106 ? ?????????? mGlobalFunctions->recurse(fp, tabs, tabsize, pass, ptype, prunearg, scope, type, basetype, count, chunk, heap, stacksize, entry,

#107 ? entrycount, NULL);

#108 ? ?????? }

#109 ? ?????? mStates->recurse(fp, tabs, tabsize, pass, ptype, prunearg, scope, type, basetype, count, chunk, heap, stacksize, entry, entrycount, NULL);

#110 ? ?????? break;

?

全局的作用域檢查。

#111 ? ?? case LSCP_SCOPE_PASS1:

#112 ? ?????? {

#114 ? ?????????? // zeroth, add library functions to global scope

#115 ? ?????????? S32 i;

#116 ? ?????????? char *arg;

#117 ? ?????????? LLScriptScopeEntry *sentry;

#118 ? ?????????? for (i = 0; i < gScriptLibrary.mNextNumber; i++)

#119 ? ?????????? {

#120 ? ?????????????? // First, check to make sure this isn't a god only function, or that the viewer's agent is a god.

#121 ? ?????????????? if (!gScriptLibrary.mFunctions[i]->mGodOnly || mGodLike)

#122 ? ?????????????? {

#123 ? ?????????????????? if (gScriptLibrary.mFunctions[i]->mReturnType)

#124 ? ?????????????????????? sentry = mGlobalScope->addEntry(gScriptLibrary.mFunctions[i]->mName,

#153 ? entrycount, NULL);

#154 ? ?????????? break;

#155 ? ?????? }

?

第二次作用域檢查，主要檢查跳轉、函數調用和狀態轉換。

#156 ? ?? case LSCP_SCOPE_PASS2:

#157 ? ?????? // now we're checking jumps, function calls, and state transitions

#158 ? ?????? if (mGlobalFunctions)

#159 ? ?????????? mGlobalFunctions->recurse(fp, tabs, tabsize, pass, ptype, prunearg, mGlobalScope, type, basetype, count, chunk, heap, stacksize, entry,

#162 ? ?????? break;

?

對腳本的類型進行檢查。

#163 ? ?? case LSCP_TYPE:

#164 ? ?????? // first we need to check global variables

#165 ? ?????? if (mGlobals)

#172 ? ?????? mStates->recurse(fp, tabs, tabsize, pass, ptype, prunearg, scope, type, basetype, count, chunk, heap, stacksize, entry, entrycount, NULL);

#173 ? ?????? break;

確定所有腳本需的資源大小。
