• The Netwide Assembler (NASM) is an assembler and disassembler for the Intel x86 architecture. It can be used to write 16-bit, 32-bit and 64-bit programs.NASM is considered to be one of the most popular assemblers for Linux. NASM was originally written by Simon Tatham with assistance from Julian Hall. As of 2016, it is maintained by a small team led by H.
• Install MASM (Assembly language) on Windows 7. The good old legacy MASM 6.11 (DOS) is a 16-bit version, that unfortunately only works on Windows XP and earlier versions of Windows. However there is always some way to emulate the older softwares and run them without any compatibility issues.

The Microsoft Macro Assembler (MASM) is an x86 assembler for Microsoft Windows that uses the Intel syntax. The current versions of MASM exist in 2 flavors, the first one understands 16-bit and 32-bit assembly sources, the latter (ML64 is restricted to 64-bit sources. The Microsoft Macro Assembler (MASM) is an assembler for the x86 family of microprocessors, originally produced Microsoft MS-DOS operating system. The features of MASM are listed below: i.

SASM (SimpleASM) - simple Open Source crossplatform IDE for NASM, MASM, GAS, FASM assembly languages. SASM has syntax highlighting and debugger. The program works out of the box and is great for beginners to learn assembly language. SASM is translated into Russian, English, Turkish (thanks Ali Goren), Chinese (thanks Ahmed Zetao Yang), German (thanks Sebastian Fischer), Italian (thanks Carlo Dapor), Polish (thanks Krzysztof Rossa), Hebrew (thanks Elian Kamal), Spanish (thanks Mariano Cordoba). Licensed under the GNU GPL v3.0. Based on the Qt.

Download for Windows
Download for Linux

To load SASM for Linux choose your distribution in window 'Build Results' on the right.

Also you can build SASM from sources, placed in GitHub repository or download SASM in zip-archive for Windows.

If you are Mac user, this article about installing SASM on Mac may help you (thanks Brian R. Hall).

About the program

In SASM you can easily develop and execute programs, written in NASM, MASM, GAS or FASM assembly languages. Enter code in form and simply run your program. In Windows SASM can execute programs in separate window. Enter your input data in 'Input' docking field. In 'Output' field you can see the result of the execution of the program. Wherein all messages and compilation errors will be shown in the form on the bottom. You can save source or already compiled (exe) code of your program to file and load your programs from file.

SASM supports working with many opened projects – new files are opened and created in new tabs. At the exit from SASM current set of opened files saved. At the next start you can restore previous session. In settings you can set font, color scheme and initial text. SASM is translated into Russian, English, Turkish (thanks Ali Goren), Chinese (thanks Ahmed Zetao Yang), German (thanks Sebastian Fischer), Italian (thanks Carlo Dapor), Polish (thanks Krzysztof Rossa), Hebrew (thanks Elian Kamal), Spanish (thanks Mariano Cordoba). All dialog windows in SASM is docking - you can choose one of many positions of them position. Also it is possible to reassign the hotkeys.

Standard 'Edit' menu extended with abilities to comment/uncomment piece of source code and to create/delete indent with 4 spaces (Tab/Shift+Tab).

In my program you can debug programs using the interface to the debugger gdb. You can watch values of variables and registers. Also you can set breakpoints and move through debugged program. In additional it is possible to perform any gdb command and see its result in the log on the bottom part of window.

Masm Assembler Syntax Highlighter

SASM supports 4 working with assemblers - NASM, MASM, GAS and FASM in 2 modes - x64 and x86. You can choose mode in settings on 'Build' tab. Also there you can change assembler and linker options and choose programs for assembling and linking.

Troubleshooting

If you have something does not work (errors occur when compiling, debugging, etc.), please read the chapter 'Troubleshooting' in the help of the program (F1) or on the project Wiki on GitHub. Perhaps there you will find useful advice to solve your problems.

'io.inc' NASM macro library

SASM includes crossplatform input/output library 'io.inc' for NASM. It contains I/O macro and 2 additional macro: CMAIN - entry point and CEXTERN for invoking functions, located in C language libraries ('CEXTERN printf' for example).

Macro name	Description
PRINT_UDECsize, data PRINT_DEC size, data	Print number data in decimal representation. size – number, giving size of data in bytes - 1, 2, 4 or 8 (x64).data must be number or symbol constant, name of variable, register or address expression without size qualifier (byte[], etc.). PRINT_UDEC print number as unsigned, PRINT_DEC — as signed.
PRINT_HEXsize, data	Similarly previous, but data is printed in hexadecimal representation.
PRINT_CHARch	Print symbol ch. ch - number or symbol constant, name of variable, register or address expression without size qualifier (byte[], etc.).
PRINT_STRINGdata	Print null-terminated text string. data - string constant, name of variable or address expression without size qualifier (byte[], etc.).
NEWLINE	Print newline ('n').
GET_UDECsize, data GET_DECsize, data	Input number data in decimal representation from stdin. size – number, giving size of data in bytes - 1, 2, 4 or 8 (x64). data must be name of variable or register or address expression without size qualifier (byte[], etc.). GET_UDEC input number as unsigned, GET_DEC — as signed. It is not allowed to use esp register.
GET_HEXsize, data	Similarly previous, but data is entered in hexadecimal representation with 0x prefix.
GET_CHARdata	Similarly previous, but macro reads one symbol only.
GET_STRINGdata, maxsz	Input string with length less than maxsz. Reading stop on EOF or newline and 'n' writes in buffer. In the end of string 0 character is added to the end. data - name of variable or address expression without size qualifier (byte[], etc.). maxsz - register or number constant.

Implementation

Windows

As NASM assembler used nasm 2.11.02, as linker - gcc 4.6.2 from MinGW (gcc 4.8.1 from MinGW64 in x64 mode) or ld 2.22 from MinGW (ld 2.23.2 from MinGW64 in x64 mode).

SASM 3.0 and greater contains fasm 1.71.39 and gas 2.23.1 from MinGW (gas 2.23.2 from MinGW64).

Also SASM contains gdb debugger from MinGW and 'io.inc' macro library.

All assemblers (excluding MASM) are included in SASM and you can use they right away after their choice. MASM assembler can not be included in the assembly because of its license. To use it, you should install MASM on your computer from site https://www.masm32.com/ and specify path to MASM assembler (ml.exe, path usually 'C:/masm32/bin/ml.exe') and to MASM linker (link.exe, path usually 'C:/masm32/bin/link.exe') in according fields on 'Build' tab in settings.

On Windows SASM is ready for work immediately after installation.

Linux

For correct working on Linux must be installed next packages: nasm or gas (if you will use they, fasm already included in SASM), gcc, gdb (for debugging). MASM in Linux is not supported.

More information about SASM you can see on project Wiki on GitHub.
