2019-11-15	arch: teach sparse about -fshort-wchar	Luc Van Oostenryck	1	-0/+6
	This is useful in cgcc for supporting Cygwin which doesn't use a 32-bit type for wchar_t. Signed-off-by: Luc Van Oostenryck <luc.vanoostenryck@gmail.com>
2019-10-30	arch: add an option to specify the desired arch: --arch=<arch>	Luc Van Oostenryck	4	-0/+106
	Sparse is universal in the sense that the same executable can be used for all architectures. For this, most arch-specific setting can be set with an option and the default values are taken from the host machine. This is working nicely for native targets. However, for cross- compilation, while seeming to work relatively well (thanks to the kernel build system using -m32/-m64 for all archs, for example) things can never work 100% correctly. For example, in the case an X86-64 host machine is used for an ARM target, the kernel build system will call sparse with -m32, Sparse will 'autodetect' the target arch as i386 (x86-64 + -m32) and will then predefine the macro __i386__. Most of the time this is not a problem (at least for the kernel) unless, of course, if the code contains something like: #ifdef __i386__ ... #elif __arm__ ... So, add an option --arch=<arch> to specify the target architecture. The native arch is still used if no such flag is given.
