Special builds of Thorium for SSE3, etc.
THIS REPO NOW ONLY HOSTS SPECIAL BUILDS. SSE3, AVX, and AVX2 RELEASES ARE ALL IN THE SAME REPO FOR A GIVEN OS.
For MacOS, Android, and Raspberry Pi, I have made new repositories for each one as per https://github.com/Alex313031/Thorium-Special/releases/tag/migrate-final Please find links in there.
This repo is for running Thorium on systems with CPUs that lack AVX. This generally includes CPUs older than the year 2012.
-- Simply a seperate repo for builds of Thorium https://github.com/Alex313031/Thorium that have modified compiler flags flags or args.gn flags for specific processors or use cases. I will sometimes put builds that don't need AVX here.
- NEW: Thorium Special now has builds for MacOS. Both x64 and ARM64 (for M1 Macs) are available. Kudos to @midzer for building them on his M1 Mac.
- NEW: Thorium Special now has ARM64 Raspberry Pi builds for the Pi 3B+ and Pi 4 The name will have ARM64 in the name.
- NEW: Thorium Special now has Android Builds (ARM64 and ARM32)
– Windows builds are here > https://github.com/Alex313031/Thorium-Win
– AVX2 builds are here > https://github.com/Alex313031/Thorium-AVX2/ 
Releases will have the architecture name in the name and the .deb package to differentiate them.
Clone and do everything in https://github.com/Alex313031/Thorium except before building, copy the contents of one of the build.gn files in this repo to //chromium/build/config/compiler/, and modify as per below.
You can modify BUILD.gn (which goes in //chromium/build/config/compiler/) to suit your system by referring to the list of microarchitectures and associated -march flags here > https://gcc.gnu.org/onlinedocs/gcc/x86-Options.html You can use the contents of ICELAKE.gn, BULLDOZER.gn, HASWELL.gn, MSSE4.2.gn, MSSE4.0.gn, or MSSE3.gn. Theoretically, any CPU supporting at least SSE3 can have their -march dialed in to specifically target them for best performance.
You could modify args.gn by referencing the args.list file (also in the regular Thorium repo).
Thanks for using Thorium!
