PATCHES - Thorium — ContextQMD

List of patches/changes/features included in Thorium

Compiler modifications include SSE4.2, AVX, AES, and CFLAGS, LTO flags, and import_instr_limit flags set to /03, 3, and 30, respectively.
NEW > Added some LLVM LOOP optimizations as -mllvm flags. See here > https://github.com/RobRich999/Chromium_Clang/issues/26#issuecomment-976883814

FTP Support - Thorium is the only current browser that still supports ftp:// sites. See the patch I use. See https://www.vogons.org/viewtopic.php?t=66653 for fun FTP sites.

.desktop files are created for Thorium itself and content-shell (named thorium-shell).

There are also additional desktop actions: when right clicking the Thorium launcher it gives three additional desktop actions, one to open thorium-shell, another to open in Safe Mode which disables any flags one has set in chrome://flags until the next launch, and lastly to open in Dark Mode which appends the --force-dark-mode flag.
