The clang integrated assembler fails to build one file with a complex asm instruction: arch/arm/mach-omap1/ams-delta-fiq-handler.S:249:2: error: invalid instruction, any one of the following would fix this: mov r10, #(1 << (((NR_IRQS_LEGACY + 12) - NR_IRQS_LEGACY) % 32)) @ set deferred_fiq bit ^ arch/arm/mach-omap1/ams-delta-fiq-handler.S:249:2: note: instruction requires: armv6t2 mov r10, #(1 << (((NR_IRQS_LEGACY + 12) - NR_IRQS_LEGACY) % 32)) @ set deferred_fiq bit ^ arch/arm/mach-omap1/ams-delta-fiq-handler.S:249:2: note: instruction requires: thumb2 mov r10, #(1 << (((NR_IRQS_LEGACY + 12) - NR_IRQS_LEGACY) % 32)) @ set deferred_fiq bit ^ The problem is that 'NR_IRQS_LEGACY' is not defined here. Apparently gas does not care because we first add and then subtract this number, leading to the immediate value to be the same regardless of the specific definition of NR_IRQS_LEGACY. Neither the way that 'gas' just silently builds this file, nor the way that clang IAS makes nonsensical suggestions for how to fix it is great. Fortunately there is an easy fix, which is to #include the header that contains the definition.

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.
