gcov: reuse kbasename helper

2013-11-13T03:09:34Z

To get name of the file from a pathname let's use kbasename() helper. Signed-off-by: Andy Shevchenko Cc: Jingoo Han Cc: Peter Oberparleiter Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

gcov: add support for gcc 4.7 gcov format

2013-11-13T03:09:34Z

The gcov in-memory format changed in gcc 4.7. The biggest change, which requires this special implementation, is that gcov_info no longer contains array of counters for each counter type for all functions and gcov_fn_info is not used for mapping of function's counters to these arrays(offset). Now each gcov_fn_info contans it's counters, which makes things a little bit easier. This is heavily based on the previous gcc_3_4.c implementation and patches provided by Peter Oberparleiter. Specially the buffer gcda implementation for iterator.

gcov: move gcov structs definitions to a gcc version specific file

2013-11-13T03:09:34Z

Since also the gcov structures(gcov_info, gcov_fn_info, gcov_ctr_info) can change between gcc releases, as shown in gcc 4.7, they cannot be defined in a common header and need to be moved to a specific gcc implemention file. This also requires to make the gcov_info structure opaque for the common code and to introduce simple helpers for accessing data inside gcov_info.

kernel: replace strict_strto() with kstrto()

2013-09-12T22:38:03Z

The usage of strict_strto*() is not preferred, because strict_strto*() is obsolete. Thus, kstrto*() should be used. Signed-off-by: Jingoo Han Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

kernel/gcov: remove depends on CONFIG_EXPERIMENTAL

2013-01-11T19:39:33Z

The CONFIG_EXPERIMENTAL config item has not carried much meaning for a while now and is almost always enabled by default. As agreed during the Linux kernel summit, remove it from any "depends on" lines in Kconfigs. Cc: WANG Cong Signed-off-by: Kees Cook Acked-by: Peter Oberparleiter

gcov: disable CONSTRUCTORS for UML

2011-07-26T23:49:45Z

Selecting GCOV for UML causing configuration mismatch: warning: (GCOV_KERNEL) selects CONSTRUCTORS which has unmet direct dependencies (!UML) Constructors are not needed for UML.

gcov: disable CONFIG_CONSTRUCTORS when not needed by CONFIG_GCOV_KERNEL

2011-06-16T03:04:01Z

CONFIG_CONSTRUCTORS controls support for running constructor functions at kernel init time. According to commit b99b87f70c7785ab ("kernel: constructor support"), gcov (CONFIG_GCOV_KERNEL) needs this. However, CONFIG_CONSTRUCTORS currently defaults to y, with no option to disable it, and CONFIG_GCOV_KERNEL depends on it. Instead, default it to n and have CONFIG_GCOV_KERNEL select it, so that the normal case of CONFIG_GCOV_KERNEL=n will result in CONFIG_CONSTRUCTORS=n. Observed in the short list of =y values in a minimal kernel configuration.
