Go Toolchains - The Go Programming Language
The go and toolchain lines can be thought of as specifying the version requirements for the module’s dependency on the Go toolchain itself, just as the require lines in go.mod specify the version requirements for dependencies on other modules. The go get command manages the Go toolchain dependency just as it manages dependencies on other modules.

The toolchain is simply tools to build software (compiler, assembler, linker, libraries, and a few useful utilities).

In this case the important part is host-independent - that is independent of the tools downloaded.

There are several reasons why you might want to rebuild the tools:

  • It is harder to sneak in backdoors (though not impossible)
  • Compile parameters can be tweaked to fit your system and not just being a general binary.
  • You get the newest version of the tools.

LFS rebuilds the toolchain (i.e. the compiler, the linker, the assembler, and the libraries used by all of them) three times:

  • The first time uses the toolchain of the host system to build a new toolchain (gcc, ld, binutils, glibc, etc)on the target system. These tools will be linked to shared libraries on the host system, which would not be present were you to boot into your target system at this time. So...
  • The second time the toolchain is built against the libraries installed on the target machine. This means the toolchain will work if you boot into the target system, but there is still some possibility things may be linked against the host system, and regardless the toolchain was still compiled with optimizations targeted at the host system, not the target system. So...
  • The third time is the charm, and this time the toolchain will be completely "sanitized" of any links or attachments to your host system, and optimized for your target system.

This is perhaps the single most important part of building an LFS system, and it's very important to pay close attention to the instructions. In all of the LFS systems I've built (four to-date), this has been the one section where I've run into problems. Sometimes those problems didn't show up until much later, which as you can imagine is very frustrating.

I have always used some predefined toolchains that I didn’t create. So now I want to understand, create and modify different aspects of the toolchain - using ARM GCC and CMake, to be specific.

Toolchain
The main toolchains in software development are collections of tools used for building and compiling code into executable programs, libraries, and more. These toolchains vary by the programming languages they support, the target platforms they are designed for, and the specific tasks they excel at, such as optimization for performance or size.
