                                CROSS COMPILER TOOLCHAINS - README

This branch contains some of the latest cross compiler toolchains I've built for Android kernel development, it contains the following:

  • "Linaro GCC 4.9.3-2014.12 Toolchains" include Linaro GCC 4.9-2014.12 (4.9.3) and Linaro GDB 7.8-2014.09

You can find other zipped toolchain builds on my Mediafire folder, please take a look at the original thread on XDA Developers forum at this link: http://forum.xda-developers.com/showthread.php?t=2098133

  • The toolchains with "arm-cortex_a15-linux-gnueabi" prefix are optimized for Cortex-A15 cpu with Neon-VFPv4 technology support
  • The toolchains with "arm-cortex_a9-linux-gnueabi" prefix are optimized for Cortex-A9 cpu with Neon-VFPv3 technology support
  • The toolchains with "arm-cortex_a8-linux-gnueabi" prefix are optimized for Cortex-A8 cpu with Neon-VFPv3 technology support (like Qualcomm Snapdragon Scorpion cpu mounted on Samsung S Plus I9001)
  • The toolchains with "arm-linux-gnueabi" prefix are built for generic Cortex-A cpu and configured with similar settings to those of the latest Linaro toolchains

I hope you find them useful... Let me know. Thanks!
