Rely on the compiler to be correctly set up to generate
|
|
appropriate code for the target variant.
|
|
|
|
This exposes the Thumb option, as it is no longer auto-selected.
|
|
The "Use BX" no longer depends on supported CPU to be selected,
|
|
so it now defaults to 'n' as it shall work by default on CPUs
|
|
that do not have BX.

|
|
- This is the processor type of your CPU. This information is used for
|
|
- optimizing purposes. To build a library that will run on all ARMCPU
|
|
- types (albeit not optimally fast), you can specify "Generic Arm" here.
|
|
- If you pick anything other than "Generic Arm", there is no guarantee
|
|
- that uClibc will even run on anything other than the selected
|
|
- processor type.
|
|
-
|
|
- Here are the settings recommended for greatest speed:
|
|
- - "Generic Arm" select this if your compiler is already setup to
|
|
- optimize things properly, or if you want to run on pretty much
|
|
- everything, or you just don't much care.
|
|
- - For anything else, pick the ARM core type that best matches the
|
|
- cpu you will be using on your device.
|
|
-
|
|
- If you don't know what to do, choose "Generic Arm".
