  • _arch_mem_top variable representing top of memory, along with related kernel tweaks and macros
  • Example memory-testing program demonstrating use of new 32MB features
  • Patches for GCC 4.7.4 and 9.3.0 (including Apple Silicon patch) supporting stack changes
  • Patches for GCC 4.7.4 and 9.3.0 adding builtin defines KOS_GCC_PATCHED, KOS_GCC_PATCHLEVEL, and KOS_GCC_32MB.
