Note on binary architectures
CPU architecture labels used by Intel and others can be confusing and have changed over time. Here's a summary of the labels and directory names commonly used:
- 32, ia32, x86
- legacy 32-bit x86 generations up to Pentium 4 and Intel Core.
- em64t, intel64, Intel-64, x86_64, AMD-64
- 64-bit generations of the Xeon branded CPUs, and the Core 2 generation, mostly compatible with AMD's Opteron and later.
- 64, ia64, Itanium
- Itanium – limited ia32 support, but none for x86_64; not used on Carbon.
