Stack is implemented by the LMEM register file. Unaligned accesses to LMEM are not allowed. Accesses also have to be 4B wide. To support stack we need to make sure offsets of pointers are known at translation time (for now) and perform correct load/mask/shift operations. Since we can access first 64B of LMEM without much effort support only stacks not bigger than 64B. Following commits will extend the possible sizes beyond that.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
