Clang integration?

[infinigon]

Are there any plans for integrating Code::Blocks with Clang? I've only looked over it briefly, but it looks to integrate much more tightly with IDE's, like aiding with static code analysis and transformation
http://clang.llvm.org/features.html#applications

Also, I don't know whether Clang's AST could benefit Code::Blocks' code-completion redesign?

Not sure How hard to integrate Clang to codeblocks. 

Currently, clang is divided into the following libraries and tool:

    * libsupport - Basic support library, from LLVM.
    * libsystem - System abstraction library, from LLVM.
    * libbasic - Diagnostics, SourceLocations, SourceBuffer abstraction, file system caching for input source files.
    * libast - Provides classes to represent the C AST, the C type system, builtin functions, and various helpers for analyzing and manipulating the AST (visitors, pretty printers, etc).
    * liblex - Lexing and preprocessing, identifier hash table, pragma handling, tokens, and macro expansion.
    * libparse - Parsing. This library invokes coarse-grained 'Actions' provided by the client (e.g. libsema builds ASTs) but knows nothing about ASTs or other client-specific data structures.
    * libsema - Semantic Analysis. This provides a set of parser actions to build a standardized AST for programs.
    * libcodegen - Lower the AST to LLVM IR for optimization & code generation.
    * librewrite - Editing of text buffers (important for code rewriting transformation, like refactoring).
    * libanalysis - Static analysis support.
    * libindex - Cross-translation-unit infrastructure and indexing support.
    * clang - A driver program, client of the libraries at various levels.

seems: librewrite can support code refactoring.

Eh, I just found this from about a year ago:

Sorry about the redundancy (note to self: GIYF), but still, this would be useful to have, especially for the future as Clang becomes more mature and capable.

made a build of llvm/llvm-gcc svn and binutils.

includes native python and gdb.

ftp://90.184.233.166:21/LLVM.7z

can be used with msys also if you add the folder to fstab instead of the normal mingw.
like so C:/LLVM. /mingw

for msys autotool based builds you might have to tell the autotools what C and C++ compilers to use like this CC=llvm-gcc CXX=llvm-g++

mingw32-make is not included but the one from mingw site works just fine.

only handles c/c++ and fortran atm. ada cannot be built with gcc-4.5.1 i use to bootstrap as the version of gcc from llvm is a rather ancient one 4.2.1

So, this is a full package that can replace the mingw-gcc ??

Edit: it was 120M + .... to big...

BTW:
the link should be fixed to:

ftp://90.184.233.166:21/LLVM.7z

yep noticed fixed the link

if you only need c/c++ or fortran support it can replace the standard mingw.

there are a few quirks to get codeblocks running with it for one gcc and g++ are prefixed with llvm- so need to tell it that. the same goes for gfortran.

sorry about the size ill see if i can hammer it down some but this is mostly a test build.

Did you enable optimization ?
Otherwise, you create a debug-build and that's mauch larger (and slower).

There is switch for the configure-script, I don't know exactly how it is named (not on my system), but I guess it was --enable-optimization.
Search for it with ./configure --help .

If you use makefiles directly, the switch is named ENABLE_OPTIMIZED=1 .

aye was set as debug compiling a release version now should be up in some hours unless i run into problems.

For those of you who don't know ... Clang has successfully compiled the Linux Kernel ... hmmm ...

great compiler!!!

I have one glance on the source code of clang's lexer and parser. it was quite (too) complex. All the lexer/ parser was hand-written. and their hand-written lexer doesn't distinguish with any identifiers and keyword. instead, they use an identifier hash table, once the lexer get a general identifier, it will be looked up in the identifier table to see if it was a keyword or a macro definition or a new real identifier...

the code snippet of parsing a function declaration was more than 800 lines. :shock:

its good but a major pain in the beep beep! to compile.

the gcc to bootstrap it has neither thread nor exception support so im bootstrapping my version with gcc-4.5.1 and while it does seem to work for c/c++ and fortran ada barfs loudly because the ada compiler changed a lot from the 4.2 version (bad casing of NUL) error.

also bootstrapping the gcc 4.2 compiler seems to run out of stack space (pthread bug i suspect) so can only make a none bootstrapped gcc for the moment.

theres been some work to use gcc's plugin system with a plugin called dragonegg to use the llvm compiler with unmodified gcc 4.5. unfortunatly its linux/mac only atm so were stuck with the old gcc for the moment.

Please keep in mind, that this is the C::B forum, not the clang/llvm forum.

[reckless]

ofc. jens sorry about that.

still building so ill post when theres a new release for those who want to try it with cb.

ok new version up, same download link.

ok new version up, same download link.

strange, when I click on the ftp link, it opened a folder... (windows firefox)
