Daniel Marjamäki 5e9b7a6749 Cleanup AST tests. The best would be if 'operators' in declarations was not included at all in the AST. 2019-05-04 07:31:59 +02:00
Rikard Falkeborn c7d7f8738c Optimize astStringVerbose() for large arrays (#1815)
Change the astStringVerbose() recursion to extend a string instead of
returning one. This has the benefit that for tokens where the recursion
runs deep (typically large arrays), the time savings can be substantial
(see comments on benchmarks further down).

The reason is that previously, for each token, the astString of its
operands was constructed, and then appended to this tokens astString.
This led to a lot of unnecessary string copying (and with that
allocations). Instead, by passing the string by reference, the number
of temporary strings is greatly reduced.

Another way of seeing it is that previously, the string was constructed
from end to beginning, but now it is constructed from the beginning to
end. There was no notable speedup by preallocating the entire string
using string::reserve() (at least not on Linux).

To benchmark, the changes and master were tested on Linux using the
commands:

	make
	time cppcheck --debug --verbose $file >/dev/null

i.e., the cppcheck binary was compiled with the settings in the
Makefile. Printing the output to screen or file will of course take
longer time.

In Trac ticket #8355 which triggered this change, an example file from the
Wine repository was attached. Running the above cppcheck on master took
24 minutes and with the changes in this commmit, took 22 seconds.

Another test made was on lib/tokenlist.cpp in the cppcheck repo, which is
more "normal" file. On that file there was no measurable time difference.

A synthetic benchmark was generated to illustrate the effects on dumping
the ast for arrays of different sizes. The generate code looked as
follows:

	const int array[] = {...};

with different number of elements. The results are as follows (times are
in seconds):

	N	master optimized
	10	0.1    0.1
	100	0.1    0.1
	1000	2.8    0.7
	2000	19     1.8
	3000	53     3.8
	5000	350    10
	10000	3215   38

As we can see, for small arrays, there is no time difference, but for
large arrays the time savings are substantial.

Paul Fultz II a90caa7e5a Fix issue 9006: False positive: Return value of function std::move() is not used.
This is trying to fix the issue by fixing the ast and symbol database. First, the ast nodes will be created for the init list and the symbol database will not mark it as a scope. I am not sure if this is the correct approach as I dont really understand how the AST part works.

It did change the AST for `try {} catch (...) {}` but that is because it incorrectly treats `try {}` as an initializer list.

Rikard Falkeborn 6a3dd9a185 Handle concatenated string and char literals
This handles concatenated strings and characters from simplecpp.
Previously, L'c' would be preprocessed to the tokens  "L" and "'c'".
cppcheck would then remove the "L" token and set "'c'" to be a wide
character literal. Now, it needs to remove the prefix instead.

When doing this, add handling of utf32 encoded literals (U) and UTF-8
encoded literals (u8).

- Fixed simplifyStaticConst() to handle more patterns. It did not work at the beginning of the token list and for function arguments
- Reimplemented Tokenizer::simplifyStdType()
-> properly support all possible ways to declare integers as requested by the standard, instead of only a few common permutations of "unsigned|signed", "short|char|long|int"
-> Fixed parsing of _Complex/complex types
