How to see result of MASM directives such as PROC, .SETFRAME. .PUSHREG
MASM (Microsoft Macro Assembler) directives such as PROC
, .SETFRAME
, and .PUSHREG
are used for defining procedures, setting up stack frames, and preserving registers, respectively. These directives are primarily used during assembly to generate the corresponding machine code instructions.
To see the result of these MASM directives, you need to disassemble the assembled binary code. Here's an example of how you can disassemble a compiled MASM program to view the machine code instructions:
Assemble your MASM source code using MASM or another compatible assembler. For example, if your MASM source code is in a file called
program.asm
, you can use the following command to assemble it:shellml /c /Zi program.asm
This command will generate an object file (
program.obj
) containing the compiled machine code.Link the object file to create an executable. Use the following command:
shelllink /debug program.obj
This will generate an executable file (
program.exe
) with debug information.Use a disassembler tool, such as
dumpbin
orobjdump
, to view the disassembled machine code. For example, to usedumpbin
on Windows, run the following command:shelldumpbin /disasm program.exe
This will display the disassembled machine code instructions, including the instructions generated by MASM directives like
PROC
,.SETFRAME
, and.PUSHREG
.
By disassembling the compiled binary code, you can observe the machine code instructions that correspond to the MASM directives you used in your source code. This allows you to analyze how the directives are translated into actual machine code instructions by the assembler.
Note that the disassembly output will depend on the specific processor architecture and the version of the assembler tool you are using. Make sure to consult the documentation for the disassembler tool you are using to understand the disassembly output format and interpret the machine code instructions correctly.
