I'm afraid that doesn't make a blind bit of difference to the kernel - it passes the relevent optimization flags to gcc which tell the compiler which instructions to use (based upon the CPU architecture) and how to schedule those instructions (based upon the CPU type(s) chosen in the kernel configuration.) All that an "optimized" toolchain is is a toolchain with a different default optimization selected. -- Russell King Linux kernel 2.6 ARM Linux - http://www.arm.linux.org.uk/ maintainer of: -- To unsubscribe from this list: send the line "unsubscribe linux-embedded" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
