Editor's Notes
- #4: Mention General Purpose ARM JDK for Micro Server Market.
- #5: Mention that we¡¯re working on hard-float ABI implementations for ARMv7 (ARMv6 Eval).
- #6: Many OS,Toolchains and native apps are still running on Soft Float ABI. This means they can run on ARM bases systems with and without a VFPThose OS and toolchains supporting HardFP API only run on systems with VFP.
