Saigo allows us to get rid of PNaCl limitations (like old C++14 from Clang 3.6) before doing a bigger jump to Wasm, here are some discussions on the topic:

• Consider updating NaCl as an alternative to WebAssembly DaemonEngine/Daemon#795
• Compiling Freetype and Lua as submodules for nexe/wasm cgame/sgame #3189

Roadmap:

• Add support for Saigo into the CMake build configuration
  • Early support of the Saigo toolchain DaemonEngine/Daemon#981
  • Early support of the Saigo toolchain #2862
• Make possible to build Lua and Freetype with Saigo
  • Lua and FreeType submodule #3195
  • FreeType submodule DaemonEngine/Daemon#1446
• Provide c/sgame dependencies as submodules
  • Clone Lua repository
  • Add Lua as submodule
  • Clone Freetype repository
  • Add Freetype as submodule
• Provide Saigo in external_deps
  • Find a way to build Saigo compiler
  • Find a way to package Saigo compiler
  • Find a way to build Saigo binutils
  • Find a way to package Saigo binutils
  • Find a way to fetch Saigo libc/libc++
  • Find a way to package Saigo libc/libc++
  • Package all of that in external_deps
• Fix bugs uncovered by Saigo or Clang 19+
  • Model bug with Clang 19 DaemonEngine/Daemon#1312
• Fix bugs only happening with Saigo
  • Don't use a C++ exception when parsing numbers #3196
  • System: use nacl_minidump header from libs/, Saigo doesn't ship it unlike PNaCl DaemonEngine/Daemon#1501
  • The Saigo-built arm nexe crashes #3297
    cmake: build Saigo arm nexe with -O0 to avoid a bug DaemonEngine/Daemon#1516
  • Workarounds for Saigo Clang 21 DaemonEngine/Daemon#1878
