From febe0c54031b437f713716251d6788dd481d5229 Mon Sep 17 00:00:00 2001
From: sh <sh@138bc75d-0d04-0410-961f-82ee72b054a4>

Subject: [PATCH 3/3] RTEMS: Add e6500 multilibs for PowerPC
Use 32-bit instructions only since currently there is no demand for a
larger address space. Provide one multilib with FPU and AltiVec support
and one without.
gcc/ChangeLog
* config/rs6000/rtems.h (CPP_OS_RTEMS_SPEC): Define __PPC_CPU_E6500__
for -mcpu=e6500.
* config/rs6000/t-rtems: Add e6500 multilibs.
