Re: [Ltib] gcc + uclibc for e300 core

[Steve Papacharalambous]

Hi Ryan,

You are using the correct toolchain rpm for a uClibc system.  However
this has been configured and built as a classic PowerPC architecture
toolchain which should work on an e300c3 core.

If you need a toolchain that you can optimize the output for e300c3
cores then you need to use the glibc toolchain:

http://www.bitshrine.org/gpp/freescale-powerpc-linux-gnu-4.2-187.i686.rpm

The flag: "-mcpu=e300c3" should be used,

Best regards,

Steve
