*)上面的指令防止了該函數(shù)使用的內(nèi)存區(qū)被其他函數(shù)覆蓋。如果該函數(shù)中調(diào)用了其他函數(shù),而這些被調(diào)用在程序中其他地方也被調(diào)用,你可能會(huì)需要也將這些函數(shù)排除在覆蓋分析(overlay analysis)之外。這種OVERLAY 指令能使編譯器除去上述警告信息。如果函數(shù)可以在其執(zhí)行時(shí)被調(diào)用,則情況會(huì)變得更復(fù)雜一些。這時(shí)可以采用以下幾種方法：1.主程序調(diào)用該函數(shù)時(shí)禁止中斷,可以在該函數(shù)被調(diào)用時(shí)用#pragmadisable 語(yǔ)句來(lái)實(shí)現(xiàn)禁止中斷的目的。必須使用OVERLAY 指令將該函數(shù)從覆蓋分析中除去。2.復(fù)制兩份該函數(shù)的代碼,一份到主程序中,另一份復(fù)制到中斷服務(wù)程序中。3.將該函數(shù)設(shè)為重入型。例如：void myfunc(void) reentrant {...}這種設(shè)置將會(huì)產(chǎn)生一個(gè)可重入堆棧,該堆棧被被用于存儲(chǔ)函數(shù)值和局部變量,用這種方法時(shí)重入堆棧必須在STARTUP.A51 文件中配置。這種方法消耗更多的RAM 并會(huì)降低重入函數(shù)的執(zhí)行速度。11. *** WARNING L16: UNCALLED SEGMENT, IGNORED FOR OVERLAY PROCESSSEGMENT: ?PR?_COMPARE?TESTLCD說(shuō)明：程序中有些函數(shù)（或片段）以前（調(diào)試過(guò)程中）從未被調(diào)用過(guò),或者根本沒(méi)有調(diào)用它的語(yǔ)句。這條警告信息前應(yīng)該還有一條信息指示出是哪個(gè)函數(shù)導(dǎo)致了這一問(wèn)題。只要做點(diǎn)簡(jiǎn)單的調(diào)整就可以。不理它也沒(méi)什么大不了的。解決方法:去掉COMPARE()函數(shù)或利用條件編譯#if …..#endif,可保留該函數(shù)并不編譯。C 編譯器錯(cuò)誤信息中文翻譯Ambiguous operators needparentheses不明確的運(yùn)算需要用括號(hào)括起Ambiguous symbol ``xxx``不明確的符號(hào)Argument list syntax error參數(shù)表語(yǔ)法錯(cuò)誤Array bounds missing丟失數(shù)組界限符Array size toolarge數(shù)組尺寸太大Bad character in paramenters參數(shù)中有不適當(dāng)?shù)淖址鸅ad file name format in includedirective包含命令中文件名格式不正確Bad ifdef directive synatax編譯預(yù)處理ifdef 有語(yǔ)法錯(cuò)Bad undef directive syntax編譯預(yù)處理undef 有語(yǔ)法錯(cuò)Bit field too large位字段太長(zhǎng)Call of non-function調(diào)用未定義的函數(shù)Call to function with noprototype調(diào)用函數(shù)時(shí)沒(méi)有函數(shù)的說(shuō)明Cannot modify a const object不允許修改常量對(duì)象Case outside of switch漏掉了case 語(yǔ)句Case syntax errorCase 語(yǔ)法錯(cuò)誤Code has no effect代碼不可述不可能執(zhí)行到Compound statement missing{分程序漏掉"{"Conflicting type modifiers不明確的類(lèi)型說(shuō)明符Constant expression required要求常量表達(dá)式Constant out of range incomparison在比較中常量超出范圍Conversion may losesignificant digits轉(zhuǎn)換時(shí)會(huì)丟失意義的數(shù)字Conversion of near pointer notallowed不允許轉(zhuǎn)換近指針Could not find file ``xxx``找不到XXX 文件Declaration missing ;說(shuō)明缺少"；"Declaration syntax error說(shuō)明中出現(xiàn)語(yǔ)法錯(cuò)誤Default outside of switchDefault 出現(xiàn)在switch 語(yǔ)句之外Define directive needs anidentifier定義編譯預(yù)處理需要標(biāo)識(shí)符Division by zero用零作除數(shù)Do statement must have whileDo-while 語(yǔ)句中缺少while 部分Enum syntax error枚舉類(lèi)型語(yǔ)法錯(cuò)誤Enumeration constant syntaxerror枚舉常數(shù)語(yǔ)法錯(cuò)誤Error directive :xxx錯(cuò)誤的編譯預(yù)處理命令Error writing output file寫(xiě)輸出文件錯(cuò)誤Expression syntax error表達(dá)式語(yǔ)法錯(cuò)誤Extra parameter in call調(diào)用時(shí)出現(xiàn)多余錯(cuò)誤File name too long文件名太長(zhǎng)Function call missing )函數(shù)調(diào)用缺少右括號(hào)Fuction definition out of place函數(shù)定義位置錯(cuò)誤Fuction should return a value函數(shù)必需返回一個(gè)值Goto statement missing labelGoto 語(yǔ)句沒(méi)有標(biāo)號(hào)Hexadecimal or octal constanttoo large16 進(jìn)制或8 進(jìn)制常數(shù)太大Illegal character ``x``非法字符xIllegal initialization非法的初始化Illegal octal digit非法的8 進(jìn)制數(shù)字Illegal pointer subtraction非法的指針相減Illegal structure operation非法的結(jié)構(gòu)體操作Illegal use of floating point非法的浮點(diǎn)運(yùn)算Illegal use of pointer指針使用非法Improper use of atypedefsymbol類(lèi)型定義符號(hào)使用不恰當(dāng)In-line assembly not allowed不允許使用行間匯編Incompatible storage class存儲(chǔ)類(lèi)別不相容Incompatible type conversion不相容的類(lèi)型轉(zhuǎn)換Incorrect number format錯(cuò)誤的數(shù)據(jù)格式Incorrect use of defaultDefault 使用不當(dāng)Invalid indirection無(wú)效的間接運(yùn)算Invalid pointer addition指針相加無(wú)效Irreducible expression tree無(wú)法執(zhí)行的表達(dá)式運(yùn)算Lvalue required需要邏輯值0 或非0 值Macro argument syntax error宏參數(shù)語(yǔ)法錯(cuò)誤Macro expansion too long宏的擴(kuò)展以后太長(zhǎng)Mismatched number ofparameters in definition定義中參數(shù)個(gè)數(shù)不匹配Misplaced break此處不應(yīng)出現(xiàn)break 語(yǔ)句Misplaced continue此處不應(yīng)出現(xiàn)continue 語(yǔ)句Misplaced decimal point此處不應(yīng)出現(xiàn)小數(shù)點(diǎn)Misplaced elif directive不應(yīng)編譯預(yù)處理elifMisplaced else此處不應(yīng)出現(xiàn)elseMisplaced else directive此處不應(yīng)出現(xiàn)編譯預(yù)處理elseMisplaced endif directive此處不應(yīng)出現(xiàn)編譯預(yù)處理endifMust be addressable必須是可以編址的Must take address of
