* Refactor isNullOperand out of FwdAnalysis
* Improve isNullOperand
* Fix redundantAssignment FP with unsigned zero
* isNullValue check number
* Enhance isNullOperand to handle c++ casts
Also handle cast of NULL.
* cppcheck.cpp: Check for JSON error when parsing addon .json files
This fixes that errors in JSON files given via `--addon=*.json` are
silently ignored and maybe only a part of the JSON file is used.
Now the error message which picojson can return is checked and a
corresponding error message is returned again by getAddonInfo().
* naming.json: Fix missing comma
* CLI: Fix naming violations detected by addon naming.py via naming.json
* Addon naming: Add argument for validating names of constants
* LIB: Rename functions/variables so they are valid, loosen naming rules
* GUI: Fix naming violations
* #4241: Check for address of single character passed as string
Add a check that address of a single character is not passed as argument
to argument marked as strings (using strz). The check does not warn if
the address of a character with known value '\0'.
Since ValueFlow currently does not handle global constants (see #7597),
do not warn if the variable is global to avoid FPs when the address of
a global variable assigned to '\0' is passed to a function expecting a
string.
Remove comment in docs saying strz is unused.
* Change asdf to Hello world
* Add test of address to first element in string
* Add error reporting function to getErrorMessages
* Fix strings in test
* Add tests for log10{,f,l} valid arguments
* Add log2{,f,l} to checkfunctions
* Add log1p{,f,l} to checkfunctions
* checkfunctions: Simplify check for log function limit out of range
The conditions for negative and non-negative int and float were
identical so the call to isNegative can be removed and the if-statements
be simplified.
* Add tests for invalid ranges
* Refactor loadLibErrors
This reduces the amount of code slightly and will simplify adding
more tests.
* Handle empty valid field
Before this change, the sequence <valid></valid> in a config file would
result in a segmentation fault. Now an empty field results in the error
message:
cppcheck: Failed to load library configuration file 'mycfg.cfg'. Bad attribute value '""'
* Add support for valid for floating point arguments
Previously, it was not possible to add valid ranges to floating point
arguments since it only handled integers. This made ranges not work well
for floating point arguments since arguments were cast to integers
before the ranges were handled.
Fix this by using doubles instead of integers if the argument is a float.
Add some tests for this and make sure errors are printed with enough
precision (somewhat arbitrarily chosen).
Note that it is still only possible to add integer ranges (i.e. -1:1).
* Add support for floats in configuration valid range
Now that it is possible to handle decimal arguments, there is no reason
to not allow non-integer ranges. Take care to not allow broken
configurations.
* Move check to within if-clause
* Move asin{,f,l} and acos{,f,l} input checks to config file
