Subject: [PATCH] Add support of ARC
|
||
|
|
|
||
|
|
Synopsys DesignWare ARC Processors are a family of 32-bit CPUs
|
||
|
|
which in some configurations may run Linux kernel and full stack
|
||
|
|
of applications on top of it. Among other things is Python.
|
||
|
|
|
||
|
|
With that change we allow building and usage of Numpy on ARC.
|
||
|
