While looking through the code for the CYGPKG_HAL_ARM_XSCALE_CORE package I noticed that it exports some header files to cyg/hal in the install tree. In particular, it exports hal_cache.h which contains some cache size definitions and such. Furthermore, some of the generic ARM platform HAL packages such as the CYGPKG_HAL_ARM_AEB export hal_cache.h to the same directory. Now, granted since the generic ARM targets won't include the XScale package there won't be a conflict, but out of curiousity if I did export a hal_cache.h from an XScale variant HAL package is there any guarantee as to which hal_cache.h would end up in the install tree under include/cyg/hal, i.e. the one from CYGPKG_HAL_ARM_XSCALE_CORE or the one from my XScale variant HAL package?
In a nutshell, if I export the same header file to the same directory from two different packages, which one wins out or is it undefined behavior?
