The short answer: Yes.
The slightly longer version is this: Writing A Compiler In Go is the sequel to Writing An Interpreter In Go and starts right where the other one stopped.
It also uses the code from the first book — the lexer, the parser, the AST, the object system — and extends it..
Go programs, like C and C++ programs, are fully-compiled so they require no run-time engine and no run-time translation.
In practical terms, this means that Go programs will typically run much faster than Python or JavaScript programs, especially if your program makes heavy use of the system CPU or RAM..
There are three Go compiler implementations supported by the Go team.
These are gc , the default compiler, gccgo , which uses the GCC back end, and a somewhat less mature gollvm , which uses the LLVM infrastructure..
Go programs are compiled ahead of time to native machine code (or JavaScript or WebAssembly, for some variant implementations)..
In the first phase of compilation, source code is tokenized (lexical analysis), parsed (syntax analysis), and a syntax tree is constructed for each source file.
Once tokenized, that will be parsed and used to build a syntax tree.Sep 7, 2019.

Golang doesn't rely on a virtual machine for code compilation and is directly compiled from the binary file.
That's why it is much faster than Java when it comes to application development.
Golang's automatic garbage collection also contributes to its speed and makes it much faster than Java..
“Go has excellent characteristics for scalability and services written using it typically have very small memory footprints.
Because code is compiled into a single static binary, services can also be containerised with ease, making it much simpler to build and deploy..
Go has at least two compilers, gc and gccgo .
The former was written in C, but is now written in Go itself.
While the latter is a gcc frontend written mainly in C++.
Go's libraries are written in Go..
The Go version of GCC supports automatically generating Go declarations from C code.
The facility is rather awkward, and most users should use the cgo program with the -gccgo option instead.
Compile your C code as usual, and add the option -fdump-go-spec= FILENAME ..

Go's libraries are written in Go..
Go is a compiled language.
This means we must run our source code files through a compiler, which reads source code and generates a binary, or executable, file that is used to run the program..
Executables are installed in the directory named by the GOBIN environment variable, which defaults to $GOPATH/bin or $HOME/go/bin if the GOPATH environment variable is not set.
Executables in $GOROOT are installed in $GOROOT/bin or $GOTOOLDIR instead of $GOBIN..

From the command line in the hello directory, run the go build command to compile the code into an executable.
From the command line in the hello directory, run the new hello executable to confirm that the code works.
Note that your result might differ depending on whether you changed your greetings.go code after testing it.
The Go language is small, compiles really fast, and as a result it lets your mind focus on the actual problem and less on the tool you are using to solve it.
Code, test, debug cycles are so quick that you forget you are not working with an interpreted language.
Looking at our code, you see less boilerplate and more business logic. " .
A compiler front-end for Golang implemented using Python Lex and YACC (PLY) that handles the switch and loop constructs of Golang Packing temporaries (removing all unnecesary temp variables from TAC) src/lexer.py - Generates Lex tokens from the input source file .
While the go run command is a useful shortcut for compiling and running a program when you're making frequent changes, it doesn't generate a binary executable.
The go build command compiles the packages, along with their dependencies, but it doesn't install the results.
The go install command compiles and installs the packages.
