For those leaf functions, they are likely to have no stack operations. Add is_jr_ra_ins() to determine whether jr ra has been touched before the frame_size is found. Without this patch, the get frame_size operation may be out of range and get the frame_size from the next nested function. There is no POOL32A format in uapi/asm/inst.h, so some bits here use the format of r_format instead. e.g. --------------------------------------------------------------------- | format | 31:26 | 25:21 | 20:16 | 15:6 | 5:0 | -----------------+---------+-------+-------+------------+------------ | pool32a_format | pool32a | rt | rs | jalrc | pool32axf | -----------------+---------+-------+-------+------------+------------ | r_format | opcode | rs | rt | rd:5, re:5 | func | --------------------------------------------------------------------- Signed-off-by: Jinyang He <hejinyang@loongson.cn> Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
