Paul Brook writes:
The attached patch adds support for compiling arm uClibc as pure Thumb code.
This is needed because some recent ARM codes do not implement traditional ARM
mode. Specifically:
* Cortex-M1 - An extremely minimal FPGA based core that only implements
Thumb-1 (aka ARMv6-M).
* Cortex-M3 - A Thumb-2 only ARMv7-M core.
Most of uClibc already builds in Thumb mode, all that is left are a handful of
assembly bits.
Tested on arm-uclinuxeabi.
