Extend the set of "__attribute__" shortcut macros, and remove identical (and now superfluous) definitions from a couple of source files. based on a page at robert love's blog: http://rlove.org/log/2005102601 extend the set of shortcut macros defined in compiler-gcc.h with the following: #define __packed __attribute__((packed)) #define __weak __attribute__((weak)) #define __naked __attribute__((naked)) #define __noreturn __attribute__((noreturn)) #define __pure __attribute__((pure)) #define __aligned(x) __attribute__((aligned(x))) #define __printf(a,b) __attribute__((format(printf,a,b))) Once these are in place, it's up to subsystem maintainers to decide if they want to take advantage of them. there is already a strong precedent for using shortcuts like this in the source tree. The ones that might give people pause are "__aligned" and "__printf", but shortcuts for both of those are already in use, and in some ways very confusingly. note the two very different definitions for a macro named "ALIGNED": drivers/net/sgiseeq.c:#define ALIGNED(x) ((((unsigned long)(x)) + 0xf) & ~(0xf)) drivers/scsi/ultrastor.c:#define ALIGNED(x) __attribute__((aligned(x))) also: include/acpi/platform/acgcc.h: #define ACPI_PRINTF_LIKE(c) __attribute__ ((__format__ (__printf__, c, c+1))) Given the precedent, then, it seems logical to at least standardize on a consistent set of these macros.
