<!-- PowerPC EABI variant of the 32-bit ABI implemented for 64-bit code.
Matches the Freescale/NXP Embedded ABI convention used by MPC5500/MPC55xx/MPC56xx
and other embedded PowerPC parts: r2 holds _SDA2_BASE_ (read-only small data anchor)
and r13 holds _SDA_BASE_ (read-write small data anchor). Both are preserved across
calls so the decompiler must treat them as unaffected.
