Illegal Instruction On PPC e500mc CPU Compile

[ctassell]

Hello,

I'm trying to compile the master branch on a machine with an e500mc CPU, but I get the following error:
$ make ppc
make[1]: Entering directory /home/fsiot/v8ppc/out' ACTION tools_gyp_v8_gyp_v8_snapshot_target_run_mksnapshot /home/fsiot/v8ppc/out/ppc.release/obj.target/v8_snapshot/geni/snapshot.cc Illegal instruction make[1]: *** [/home/fsiot/v8ppc/out/ppc.release/obj.target/v8_snapshot/geni/snapshot.cc] Error 132 make[1]: Leaving directory/home/fsiot/v8ppc/out'
make: *** [ppc.release] Error 2

Any ideas as to what is wrong? Here is a bit more detail on the CPU:

Sorry, this got lost in the shuffle - thus the delayed reply.

This is effectively a duplicate of issue #99 and issue #100.

Unless you're a skilled and motivated developer who can write assembly, you'll be out of luck for now.

Personally I'd like to see these freescale CPUs go, but V8 makes use of FPU instructions which on these processors are different enough that the code won't work without significant changes.
