K 10 svn:author V 8 jhibbits K 8 svn:date V 27 2016-03-11T20:43:02.422448Z K 7 svn:log V 517 Introduce SPE ABI for PowerPC Book-E Changes include: * New MACHINE_ARCH (powerpcspe) * Makefile changes to support the new MACHINE_ARCH * libc changes for fp* and setjmp * lim changes for fenv.h. * Hard-coded the SPEFSCR SPR definition (512), to avoid #include-ing machine/spr.h * Toolchain changes to enable the ABI. There is currently one gotcha -- when using -mspe, -mcpu=8540 is required, else an internal compiler error is generated in gcc. This ABI is incompatible with the standard 32-bit PowerPC ABI. END
