compiler: introduce used and maybe_unused

2007-05-09T19:30:56+00:00

__used is defined to be __attribute__((unused)) for all pre-3.3 gcc compilers to suppress warnings for unused functions because perhaps they are referenced only in inline assembly. It is defined to be __attribute__((used)) for gcc 3.3 and later so that the code is still emitted for such functions. __maybe_unused is defined to be __attribute__((unused)) for both function and variable use if it could possibly be unreferenced due to the evaluation of preprocessor macros. Function prototypes shall be marked with __maybe_unused if the actual definition of the function is dependant on preprocessor macros. No update to compiler-intel.h is necessary because ICC supports both __attribute__((used)) and __attribute__((unused)) as specified by the gcc manual. __attribute_used__ is deprecated and will be removed once all current code is converted to using __used.

[PATCH] Add const to pointer qualifiers for __chk_user_ptr and __chk_io_ptr.

2007-03-26T21:23:52+00:00

Change prototypes for __chk_user_ptr and __chk_io_ptr to take const void* instead of void*, so that code can pass "const void *" to them. (Right now sparse does not warn about passing const void* to void* functions, but that is a separate bug that I believe Josh is working on, and once sparse does check this, the changed prototypes will be necessary.)

include/linux/compiler.h: reject gcc 3 < gcc 3.2

The kernel doesn't compile with GCC <3.2, do not allow it to succeed if GCC 3.0.x or 3.1.x are used. Signed-off-by: Alistair John Strachan Signed-off-by: Adrian Bunk

[PATCH] Pass sparse the lock expression given to lock annotations

2006-10-01T07:39:26+00:00

The lock annotation macros __acquires, __releases, __acquire, and __release all currently throw away the lock expression passed as an argument. Now that sparse can parse __context__ and __attribute__((context)) with a context expression, pass the lock expression down to sparse as the context expression. This requires a version of sparse from GIT commit 37475a6c1c3e66219e68d912d5eb833f4098fd72 or later. Signed-off-by: Josh Triplett Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] Pass a lock expression to __cond_lock, like acquire and release

2006-09-29T16:18:20+00:00

Currently, __acquire and __release take a lock expression, but __cond_lock takes only a condition, not the lock acquired if the expression evaluates to true. Change __cond_lock to accept a lock expression, and change all the callers to pass in a lock expression. Signed-off-by: Josh Triplett Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] Abandon gcc-2.95.x

2006-01-09T04:14:02+00:00

There's one scsi driver which doesn't compile due to weird __VA_ARGS__ tricks and the rather useful scsi/sd.c is currently getting an ICE. None of the new SAS code compiles, due to extensive use of anonymous unions. The V4L guys are very good at exploiting the gcc-2.95.x macro expansion bug (_why_ does each driver need to implement its own debug macros?) and various people keep on sneaking in anonymous unions, which are rather nice. Plus anonymous unions are rather useful. Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
