File gcc12-fixes.patch of Package xen
References: bsc#1196545 Compiling against gcc12. Many of the failures are -Werror=array-bounds where macros from mm.h are being used. Common Examples are, include/asm/mm.h:528:61: error: array subscript 0 is outside array bounds of 'long unsigned int[0]' [-Werror=array-bounds] include/xen/mm.h:287:21: error: array subscript [0, 288230376151711743] is outside array bounds of 'struct page_info[0]' [-Werror=array-bounds] There are also several other headers that generate array-bounds macro failures. The pragmas to override are mostly in '.c' files with the exception of, xen/arch/x86/mm/shadow/private.h xen/include/asm-x86/paging.h --- a/xen/drivers/passthrough/amd/iommu_intr.c +++ b/xen/drivers/passthrough/amd/iommu_intr.c @@ -23,6 +23,10 @@ #include "iommu.h" +#if __GNUC__ >= 12 +#pragma GCC diagnostic ignored "-Warray-bounds" +#endif + union irte32 { uint32_t raw;
