Linaro/Ubuntu ARM Package Porting
This blueprint defines goals and strategy for addressing ARM-related package porting issues within Linaro and Ubuntu
Long-term high-level goals:
* Eliminate all ARM-specific build and runtime failures.
* Eliminate all cases where non-default bulid flags are used for avoiding a build failure (particularly -marm).
* Eliminate need for -mimplicit-it (i.e., add IT blocks to inline assembler wherever required).
* Review packages which may have SMP safety issues (typically every package which implements an atomics or threading API), and fix as necessary. Port atomics to the GCC intrinsics where possible and ensure correct use of memory barriers.
* All fixes should be upstreamed in addition to fixing Ubuntu+Linaro.
* Spread the knowledge about how to address porting issues as widely as possible within Linaro+Ubuntu and the wider community.
We can't get to this stage all in one go: a staged plan needs to be defined.
