An exe contains more information than just raw machine code. The OS reads this when loading it and can figure out how it should run. When you compile you generally set a target CPU, if you don't the compiler will pick your current CPU and will restrict itself to only choosing instructions that are common to your CPU and older versions of it.

Machine language is made up of binary bits 0 and 1. Machine language is also known as machine codes or object code. As machine language consists of only 0 and 1, that's why it is difficult to understand in raw form. Machine language cannot understood by humans. The CPU processes this machine code as input.

Without the source code and without adequate documentation, these tasks can be difficult to accomplish. This book outlines tools and techniques for attempting to convert the raw machine code of an executable file into equivalent code in assembly language and the high-level languages C and C++.

The code generation, which converts the Abstract Syntax Tree to machine code. Note: The packages we are going to be using (go/scanner, go/parser, go/token, go/ast, etc.) are not used by the Go compiler, but are mainly provided for use by tools to operate on Go source code. However, the actual Go compiler has very similar semantics.

9.6 Source and Machine Code. You can use the command info line to map source lines to program addresses (and vice versa), and the command disassemble to display a range of addresses as machine instructions. You can use the command set disassemble-next-line to set whether to disassemble next source line when execution stops. When run under …

Nothing stops you from writing machine code. Every good assembly manual should show the instruction encoding. Your compiler just has to write those instructions instead of writing assembly code. Don't forget that your executable file is not just machine code, it also has ELF headers saying which things go where in memory.

Example. The MIPS architecture provides a specific example for a machine code whose instructions are always 32 bits long. The general type of instruction is given by the op (operation) field, the highest 6 bits. J-type (jump) and I-type (immediate) instructions are fully specified by op.R-type (register) instructions include an additional field funct to …

You also hand code an assembler in machine code, might not be a full blown one but one that makes programming a little bit easier.
