coccinelle: misc: semantic patch to delete overly complex return code processing

2014-09-26T11:42:31Z

This semantic patch simplifies cases where the effect of the processing of a function call's return code is just to return the result of the function directly. It may also delete a local return flag variable, if this is no longer used. This was proposed by Uwe Kleine-König. Signed-off-by: Julia Lawall Signed-off-by: Michal Marek

Coccinelle: Script to replace if and BUG with BUG_ON

2014-08-06T10:10:17Z

This script detects cases where BUG() follows an if condition on an expression and replaces the if condition and BUG() with a BUG_ON having the conditional expression of the if statement as argument. Signed-off-by: Himangi Saraogi Acked-by: Julia Lawall Signed-off-by: Michal Marek

Coccinelle: Script to detect incorrect argument to sizeof

2014-08-06T10:10:17Z

This makes an effort to find cases where the argument to sizeof is wrong in memory allocation functions by checking the type of the allocated memory when it is a double pointer and ensuring the sizeof argument takes a pointer to the the memory being allocated. There are false positives in cases the sizeof argument is not used in constructing the return value. Signed-off-by: Himangi Saraogi Acked-by: Julia Lawall Signed-off-by: Michal Marek

Coccinelle: Script to use ARRAY_SIZE instead of division of two sizeofs

2014-08-06T10:10:17Z

This script detects cases where ARRAY_SIZE can be used such as where there is a division of sizeof the array by the sizeof its first element or by any indexed element or the element type. It replaces the division of the two sizeofs by ARRAY_SIZE. Signed-off-by: Himangi Saraogi Acked-by: Julia Lawall Signed-off-by: Michal Marek

coccicheck: Add unneeded return variable test

2014-06-10T12:36:30Z

This semantic patch looks for variables that are initialized with a constant, are never updated, and are only used as parameter of return. Return the constant instead of using a variable. Signed-off-by: Peter Senna Tschudin Signed-off-by: Michal Marek

coccinelle: Check for missing NULL terminators in of_device_id tables

2014-06-09T21:39:16Z

Failure to terminate an of_device_id table can lead to confusing failures depending on where the compiler places the array. Add a check to make sure these tables are terminated. Thanks to Mitchel Humpherys for coming up with the pattern initially.

Coccicheck: Remove memcpy to struct assignment test

2014-03-29T20:35:09Z

The Coccinelle script scripts/coccinelle/misc/memcpy-assign.cocci look for opportunities to replace a call to memcpy by a struct assignment. This patch removes memcpy-assign.cocci as it is not clear that this convention has an impact on the generated code. Signed-off-by: Peter Senna Tschudin Signed-off-by: Michal Marek

coccinelle: replace 0/1 with false/true in functions returning bool

2013-08-13T20:43:41Z

This semantic patch replaces "return {0,1};" with "return {false,true};" in functions returning bool. Signed-off-by: Rasmus Villemoes Acked-by: Julia Lawall Signed-off-by: Michal Marek

Coccinelle: Update the options used to the new option scheme

2013-07-03T20:58:13Z

spatch has changed its option scheme. E.g., --no_show_diff is now --no-show-diff This patch updates: - scripts/coccicheck - Semantic patches under scripts/coccinelle/ Signed-off-by: Nicolas Palix Signed-off-by: Michal Marek

scripts/coccinelle: find constant additions that could be bit ors

2013-02-22T13:26:00Z

Semantic patch (http://coccinelle.lip6.fr/) to check for constants that are added but are used elsewhere as bitmasks. Signed-off-by: Julia Lawall Signed-off-by: Michal Marek
