Thanks David and Richard for the explanations. This really helps. Looks like I need to re-read my language manual ;) Rainer 2016-01-27 18:09 GMT+01:00 Richard via cfe-users : > > [Please reply *only* to the list and do not include my email directly > in the To: or Cc: of your reply; ot

Re: [cfe-users] [cfe-dev] Issues Running Scan-build

hey Jon, i can say things a few words about the `scan-build-py`, because was my commit in the repo. :) first of all, it is an initial commit. not yet a complete replacement of the `scan-build` (the one written in Perl). that's the reason why it is not installed by any build target... but if you tr

Re: [cfe-users] [cfe-dev] Issues Running Scan-build

hey Jon, as i mentioned earlier, the `scan-build-py` is not installed by any target. so, it will stay in your source/checkout repository. (and it will be change in the future when the implementation will be mature enough to release.) at this moment it's self contained and not depend on anything, s

[cfe-users] Clang support of C++14 on Centos

Hi, I have been using Clang 3.4.2 on CentOS for a while and everything is working fine. When I try to turn on c++14 support by setting the ­std=c++11y flag, I get compilation errors like: .. In file included from /usr/bin/../lib/gcc/x86_64-redhat-linux/4.8.2/../../../../include/c++/4.

[cfe-users] Memory accesses to struct variables in LLVM IR

Hi, I'm using clang 3.4 to generate the bitcode of a C source file. The source file is the following: typedef struct __attribute__ ((__packed__)) { float x, y; } myType; myType make_float2(float x, float y) { myType f = { x, y }; return f; } int main(int argc, char* argv[]) { myType myVa

[cfe-users] CFG that accurately reflects constructor elision

I am building a standalone tool (based on LibTooling) that needs accurate information about where constructors and implicit destructors are called in C++ code. Building a CFG with options AddImplicitDtors and AddTemporaryDtors set to true seems like a good strategy for this. However, that CFG

[cfe-users] Using Clang static analysis plugins with Clang-tidy

Is it currently possible to use Clang static analysis plugins and dynamically loaded checkers with Clang-tidy? I'm attempting to setup a build system for a new project that will run the Clang-tidy checkers, the static analysis checkers, and one or more custom checkers all at once (for example the c

Re: [cfe-users] Using Clang static analysis plugins with Clang-tidy

Hi, As far as I know Clang-tidy currently does not support loading checkers from a shared library. I do not know why the patch was abandoned. We are developing a tool CodeChecker (https://github.com/Ericsson/codechecker) which can run multiple static analyzers. Currently it supports Clang Static
