FYI, with these patches applied and selecting GZIP method, I get linker errors. I've been unable to track down what's going on, but it appears to be a libgcc issue. In spite of the decompressor being built as an EABI object, gcc seems to be issuing calls to __umodsi3, which isn't in the EABI libgcc (they're called something different - don't ask.) So I think these patches need further testing and evaluation on ARM before they can be merged. Moreover, I'd like to see some comparisons between the _current_ gzip method, the new gzip method and the lzo method on ARM. I was going to get those numbers, but the platform I was going to run the tests on has died on me today. -- 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
