Assembly 如何扩展TASM宏
有没有办法用Borland的TASM扩展宏? 我想转换一个与TASM兼容的.ASM文件,以查看其所有宏的扩展。Assembly 如何扩展TASM宏,assembly,macros,tasm,Assembly,Macros,Tasm,有没有办法用Borland的TASM扩展宏? 我想转换一个与TASM兼容的.ASM文件,以查看其所有宏的扩展。 找不到任何选项来执行此操作。使用TASM的命令行选项/la生成扩展列表。从这个清单中,您可以看到高级和低级扩展。这项功能适用于所有版本的TASM,直到1988年首次发布 例如,假设您有以下TASM宏: OUTPUTMESSAGE MACRO hConsole,stringval LOCAL msg .data msg db '&stringval',0 .c
找不到任何选项来执行此操作。使用TASM的命令行选项/la生成扩展列表。从这个清单中,您可以看到高级和低级扩展。这项功能适用于所有版本的TASM,直到1988年首次发布 例如,假设您有以下TASM宏:
OUTPUTMESSAGE MACRO hConsole,stringval
LOCAL msg
.data
msg db '&stringval',0
.code
call outputString ,hConsole,OFFSET msg
ENDM ;OUTPUTMESSAGE
您希望看到以下源是如何展开的:
OUTPUTMESSAGE hConsole,<This app was assembled with TASM version >
OUTPUTMESSAGE hConsole,%??version
如果TASM没有提供一种方法(我不知道),如果值得的话,您可能需要编译源代码并将二进制文件返回到文本中。@byteprt谢谢,关于如何过滤除源代码以外的所有内容的任何想法?在您的情况下,打开或关闭列可能会很有用,但是TASM(甚至MASM)的列表文件并不是非常灵活。您也不能依赖深度列等于特定值来获取最低级别的源,因为这个数字会根据指令/宏的类型而波动,如上所示。正如@Ped7g所建议的那样,我认为您最好的选择是拆解生成的模块以获得源代码。如果您需要了解某个特定宏,列表文件至少在这方面是有用的。尽管如此,如果您编写了一个解析器脚本,只提取行中也包含[machine code]列中的值的源行,这将只提供所有扩展之后的最低级别的程序集源代码,这听起来像是您所追求的。请注意,这种技术无法可靠地再现原始数据,因为您可能会错过指令之间的转换,例如在指令之间切换数据和.code(如上所示)。再一次,你似乎回到了原点,需要使用反汇编程序。

[depth] - indicates the level of nesting of Include files and macros within your
listing file.
[line#] - is the number of the line in the listing file (not including header
and title lines). Line numbers are particularly useful when the
cross-reference feature of Turbo Assembler, which refers to lines by
line number, is used. Be aware that the line numbers in [line#] are
not the source module line numbers. For example, if a macro is
expanded or a file is included, the line-number field will continue to
advance, even though the current line in the source module stays the
same. To translate a line number (for example, one that the
cross-referencer produced) back to the source file, you must look up
the line number in the listing file, and then find that same line (by
eye, not by number) in the source file.
[offset] - is the offset in the current segment of the start of the machine code
generated by the associated assembler source line.
[machine_code] - is the actual sequence of hexadecimal byte and word values that
is assembled from the associated assembler source line.
[source] - is simply the original assembler line, comments and all. Some
assembler lines, such as those that contain only comments, don't
generate any machine code; these lines have no [offset] or [machine_
code] fields, but do have a line number.
