In this topic, I'll update everyone with a list of things I've compiled and how it was done. A lot of these are very simple as long as you have a modern GCC version on your machine. Also, if you want to tackle most things, use --without-gnu-ld as the GNU linker is broken on IRIX.
Assume that I'm using gcc 4.7.1 in all of these. They are also built for Irisware. If you wish to build things for Irisware as well, make sure to use -O2 in your CFLAGS+CXXFLAGS.

Click "show" to see how to compile GCC 4.7.3
As far as I know, this is the first guide on compiling GCC 4.7.3 on IRIX. Hopefully this will be pretty useful! A lot of this guide is copy+pasted from the last one and then just changed and added to where needed. Most of the configure lines are different and there's even a patch that wasn't necessary with 4.7.1.

/var/tmp/gccbuild/gcc-objs/gcc/xgcc  version 4.7.3 (GCC)

Prerequisites
neko texinfo, neko m4, neko tar, neko wget and at least GCC 4.3.x (all available in Nekoware)

NOTE: I tested with GCC 4.7.1, so if you have trouble compiling with GCC 4.3.x, try doing this with 4.7.1.
A decently fast machine (4.7.1 took 16+ hours to compile on my 2x 250 MHz Octane, luckily I'm using Calcifer for compilation now...)

CFLAGS and CXXFLAGS
IRISWare requires the -O2 flag.

PATH stuff:
Obviously make sure the GCC version you're going to be compiling with is in your PATH.
Also, make sure to set LD_LIBRARY_PATH properly, e.g. if you're compiling with 4.7.1 configured for IRISWare and using csh/tcsh:

Code:

setenv LD_LIBRARY_PATH /opt/local/gcc47/lib:/opt/local/gcc47/lib64:/opt/local/gcc47/lib32

Getting stuff

Make a folder in /var/tmp called gccbuild. After making it, cd there.
Next, open up your favorite editor and save this, chmod +x it, and run it to download everything you need.

Code:

wget ftp://ftp.gmplib.org/pub/gmp-5.1.3/gmp-5.1.3.tar.bz2
wget ftp://ftp.gnu.org/gnu/binutils/binutils-2.23.2.tar.bz2
wget ftp://ftp.gnu.org/gnu/mpfr/mpfr-3.1.2.tar.bz2
wget ftp://ftp.gnu.org/gnu/mpc/mpc-1.0.1.tar.gz
wget ftp://ftp.gnu.org/gnu/gcc/gcc-4.7.3/gcc-4.7.3.tar.bz2
tar jxf gmp-5.1.3.tar.bz2 && tar jxf binutils-2.23.2.tar.bz2 && tar jxf mpfr-3.1.2.tar.bz2 && tar zxf mpc-1.0.1.tar.gz && tar jxf gcc-4.7.3.tar.bz2
rm *.tar.bz2 *.tar.gz

Building
Unless otherwise stated, to build each project, cd into the directory, run the configure line I've provided, and then make by the use of

Code:

gmake -j[amount of CPUs +1]

. For example, on my Octane I used

Code:

gmake -j3

. I've heard it's a good rule of thumb to use one more CPU than you have as it makes sure they stay fed. This most definitely applies to modern systems, and it won't really hurt here. Also, it is a good idea to run

Code:

gmake -j[amount of CPUs +1] check

after compiling gmp and binutils, but it is not absolutely necessary if you are willing to live on the edge and go without these checks.

Patches
libgomp must be patched in order to correctly detect the number of CPUs.
Create /opt/local/patches/gcc473-libgomp.patch with this inside:

Code:

diff -urnp libgomp-orig/config/posix/proc.c libgomp/config/posix/proc.c

<B>IMPORTANT NOTE:</B> There is an issue that rears its head when working with gcc compilation in IRIX which seems to be undocumented in other guides. The default IRIX environment space is only 20K, that that is too small for one of the commands gmake install needs to run to install gcc. You can remedy this by running

Code:

systune ncargs 65536

, which gives you 64K of argument/environment space.

Post-build cleanup
My GCC 4.7.1 has some info on how to clean up a bit after getting it all compiled, but I don't really recommend it as it gets rid of some stuff that are useful if you want to run checks and things like that.

Checking
It is a good idea to run some gcc testsuites. Be warned, though, that these can take quite a long time.

Code:

gmake check-gcc-c
gmake check-target-libgomp
gmake check-gcc-c++
gmake check-target-libstdc++-v3

Click "show" to see how to compile latest OpenSSL stable
NOTE: At time of writing, OpenSSL 1.1.0h was the latest stable release.
You need neko_perl from the beta repo for this.
OpenSSL still works perfectly on IRIX as far as I can see, the latest version compiled without a hitch like this:

Code:

./Configure irix64-mips4-gcc --prefix=/opt/local && gmake -j5 && gmake install

Click "show" to see how to compile latest Vim stable
NOTE: At time of writing, Vim 8.1 was the latest stable release.
Vim still works well on IRIX as far as I can see, however, if you're going to be using it on a server, you do not want X support as it causes vim to take a long time to start since it tries to hook to a nonexistent X server.

Code:

./configure --prefix=/opt/local --enable-gui=no --without-x && gmake -j5 && gmake install

Click "show" to see how to compile GCC 4.7.1 (soon to be outdated)
There was already a thread on Nekochan about compiling 4.6.3 on IRIX, there's also a Chinese webpage that details installing 4.7.1.
Since Nekochan is down, I figured I should make a thread on how to do it here. Also, there are a things I came across that none of those aforementioned guides mentioned. Also, we're going to be compiling this assuming it's going to be packaged for IRISWare.

Prerequisites
neko texinfo, neko m4, neko perl, neko tar, neko wget and at least gcc 4.3.x (all available in Nekoware)
A decently fast machine (took 16+ hours to compile on my 2x 250 MHz Octane)

IRISWare requires the -O2 flag.

PATH stuff
Obviously make sure the GCC version you're going to be compiling with is in your PATH.
Also, make sure to set LD_LIBRARY_PATH properly, e.g. if you're compiling with 4.3.x and using csh:

Code:

setenv LD_LIBRARY_PATH /usr/nekoware/gcc-4.3/lib:/usr/nekoware/gcc-4.3/lib32
