-If you wish to build the toolchain yourself, beware that this process can get
-pretty tedious unless you have a powerful enough computer with plenty of
-threads to spare. A system with at least 4 to 8 total threads or more is
-recommended. You may have better success building the toolchain in ArchLinux
-especially if you want to build the most recent versions of GCC. Debian
-Buster however, may have about the same chance of success in building as
-using ArchLinux.
-
-It is recommended to stick with GCC 7.4.0 and Binutils 2.31 as this is the
-version PSn00bSDK is most tested with. Though generally, it doesn't hurt to
-try out newer versions and has been known to work flawlessly without issue.
-
-These instructions are only for Linux, though they can be adapted for
-building in Windows using MSys2 or Cygwin64. Beware that libgcc cannot
-be built under Windows as the libgcc build process depends on symlinks
-which is not supported by the operating system and is not wrapped by Msys2
-and Cygwin64. The only workaround is to first build GCC in Linux then copy
-the libgcc.a library from it to the Windows build.
-
-
-Make sure the following packages are installed prior to building:
-* make
-* build-essential or build-essentials, if you don't have GCC installed yet
-  (a host toolchain is required to build the rest of the SDK anyway).
-
-
-Building binutils:
-
-Binutils must be built first as GCC depends on binutils built for the same
-target architecture. In this case, building binutils and GCC to target
-mipsel-unknown-elf.
-
-* Download binutils source files at ftp://ftp.gnu.org. Choose a version you
-  wish to use with PSn00bSDK. The reference version that PSn00bSDK is tested
-  with most is 2.31.
-  
-* Extract the contents of the archive, preferably in a directory named
-  "toolchain" (or whatever).
-  
-* Create a directory named binutils-build inside the toolchain directory. Do
-  not create it inside the binutils directory with the source files.
-  
-* Enter the binutils-build directory and configure binutils from there
-  with the following command line:
-
-../binutils-<version>/configure --prefix=/usr/local/mipsel-unknown-elf \
---target=mipsel-unknown-elf --disable-docs --disable-nls --with-float=soft
-
-Replace <version> with the version of binutils you wish to use. You may also
-want to change the prefix argument to a path you prefer to have the toolchain
-installed to (ie. somewhere within your home directory so you wouldn't need
-root privileges to install).
-
-* Run `make -j 4` to compile binutils (-j specifies how many simultaneous
-  jobs to spawn at once, set it equal to the number of cores/threads your
-  system has available to speed up compiling).
-  
-* Run `make install-strip` to install binutils to the path specified by the
-  --prefix argument (root privileges are required if the prefix points to
-  /usr/local).
-
-
-Building gcc:
-
-With binutils built it should be possible to build the GCC toolchain. Since
-GCC is considerably larger than binutils, compile time is going to be much
-longer so it's going to take a longer while to build this.
-
-* Download gcc source files at ftp://ftp.gnu.org and choose the version you
-  wish to use with PSn00bSDK. The reference version that PSn00bSDK is tested
-  with most is 7.4.0.
-
-* Extract it to the same toolchain directory you extracted binutils in.
-
-* Enter the extracted "gcc-<version>" folder and run the following command
-  from there to download the required dependencies:
-
-./contrib/download_prerequisites
-
-* Go back and create a directory named gcc-build inside the toolchain
-  directory.
-
-* Enter the gcc-build directory and configure gcc from there with the
-  following command line:
-
-../gcc-<version>/configure --prefix=/usr/local/mipsel-unknown-elf \
---target=mipsel-unknown-elf --disable-docs --disable-nls --disable-libada \
---disable-libssp --disable-libquadmath --disable-libstdc++-v3 \
---with-float=soft --enable-languages=c,c++ --with-gnu-as --with-gnu-ld
-
-Replace <version> with the version of gcc you downloaded. The prefix path
-must match to what you've specified for binutils earlier, if you've decided
-to use a different prefix path for binutils.
-
-When building under Windows you must additionally specify --disable-libgcc,
-as libgcc cannot be built under Windows as it needs symlinks which are not
-supported by the operating system.
-
-* Run make in the same manner you built binutils with.
-
-* Run `make install-strip` to install gcc to the path specified by --prefix
-  (root privileges are required if the prefix points to /usr/local).
-  
-* Add a path to the bin directory of the toolchain into your PATH environment
-  variable by adding the following line in your .bashrc or .bash_profile file:
-  
-export PATH=$PATH:/usr/local/mipsel-unknown-elf/bin
-
-Under Windows, you'll have to add the path to the PATH environment variable
-through System Properties.
-
-
-Note regarding C++ support:
-
-C++ support in PSn00bSDK, besides compile-time features like constexpr, only
-goes as far as basic classes, namespaces and the ability to dynamically create
-and delete class objects at any point of the program. The required dependencies
-are supplied by libc of libpsn00b.
-
-Standard C++ libraries are not implemented and likely never going to be
-implemented due to bloat concerns that it may introduce. Besides, the official
-SDK lacks full C++ support as well.
-
-If you're trying to compile with C++ code and you get a linker error about
-undefined vtables, try specifying --fno-rtti to the g++ command line.
-
------------------------------------------------------------------------------
-Updating the ldscript (NO LONGER REQUIRED as PSn00bSDK now ships with its own
-linker scripts, the section below is only kept for reference):
-
-The following changes used to be required in order for basic C++ functionality
-to work in older PSn00bSDK versions. The changes define the constructor and
-deconstructor sections which are required for the relevant support functions
-in PSn00bSDK's libc library to be linked properly for C++.
-
-* Go to mipsel-unknown-elf/lib/ldscripts in the toolchain directory.
-  
-* Open elf32elmip.x in any text editor.
-
-* Locate the .text definition (with the {} brackets) and add the following
-  inside the bracket block:
-
-__CTOR_LIST__ = .;
-___CTOR_LIST__ = .;
-LONG (((__CTOR_END__ - __CTOR_LIST__) / 4) - 2)
-KEEP (*(SORT (.ctors.*)))
-KEEP (*(.ctors))
-LONG (0x00000000)
-__CTOR_END__ = .;
-. = ALIGN (0x10);
-
-__DTOR_LIST__ = .;
-___DTOR_LIST__ = .;
-LONG (((__DTOR_END__ - __DTOR_LIST__) / 4) - 2)
-KEEP (*(SORT (.dtors.*)))
-KEEP (*(.dtors))
-LONG (0x00000000)
-__DTOR_END__ = .;
-. = ALIGN (0x10);
-
-* Save script changes.
-
-Since there's no known way (at least to me -Lameguy64) to configure GCC such
-that it uses the modified ldscript as the default, you must specify the
-modified script during the linking stage of your projects with the -T
-argument, when invoking mipsel-unknown-elf-ld.
-
-Alternatively, you can make a copy of the ldscript file and modify it within
-your project directory. This is especially useful if your project uses code
-overlays.
