From ef4e8ce1beb5b93aedda5a4c1b90bfd989c6791e Mon Sep 17 00:00:00 2001 From: David Gibson Date: Mon, 7 Jul 2008 10:10:48 +1000 Subject: dtc: Enable and fix -Wpointer-arith warnings This patch turns on the -Wpointer-arith option in the dtc Makefile, and fixes the resulting warnings due to using (void *) in pointer arithmetic. While convenient, pointer arithmetic on void * is not portable, so it's better that we avoid it, particularly in libfdt. Also add necessary definition of uintptr_t needed by David Gibson's changeset "dtc: Enable and fix -Wpointer-arith warnings" (the definition comes from stdint.h, which u-boot doesn't have). -- gvb Signed-off-by: David Gibson Signed-off-by: Gerald Van Baren --- include/libfdt_env.h | 12 ++++++++++++ 1 file changed, 12 insertions(+) (limited to 'include/libfdt_env.h') diff --git a/include/libfdt_env.h b/include/libfdt_env.h index a7fd2f8d9..671c3a898 100644 --- a/include/libfdt_env.h +++ b/include/libfdt_env.h @@ -38,4 +38,16 @@ extern struct fdt_header *working_fdt; /* Pointer to the working fdt */ #define fdt64_to_cpu(x) __be64_to_cpu(x) #define cpu_to_fdt64(x) __cpu_to_be64(x) +/* + * Types for `void *' pointers. + * + * Note: libfdt uses this definition from /usr/include/stdint.h. + * Define it here rather than pulling in all of stdint.h. + */ +#if __WORDSIZE == 64 +typedef unsigned long int uintptr_t; +#else +typedef unsigned int uintptr_t; +#endif + #endif /* _LIBFDT_ENV_H */ -- cgit v1.2.3
