The same effect could be achieved using macros, for example #define DO_PRAGMA(x) _Pragma (#x) DO_PRAGMA (GCC dependency "parse.y") The standard is unclear on where a _Pragma operator can appear. From: George Necula - 2006-05-02 06:04:36 Indeed, CIL supports #pragmas only at global scope. https://ghc.haskell.org/trac/ghc/ticket/5401

This is in line with the STDC prefix on all pragmas defined by C99. Now I see the problem: cilly cannot parse pragmas inside a function only at "toplevel". >void foo() >{ >#pragma TCS_atomic > printf("hello\n"); >} This is a limitation of cilly's C-parser.

For backward compatibility, pragmas which were recognized by previous versions are still recognized without the GCC prefix, but that usage is deprecated. The function has a mechanism of indicating that it wants more input but it isn't doing it properly in this case.

We seem to both have good flow analyzers for C. In GCC version 3, all GNU-defined, supported pragmas have been given a GCC prefix. For example, #define strrchr rindex #pragma GCC poison rindex strrchr(some_string, 'h'); will not produce an error. #pragma GCC system_headerThis pragma takes no arguments. dig this Developer does not see priority in git Development Workflow being followed How difficult is it to practically detect a forgery in a cryptosystem?

Christoph L. It is destringized, by replacing all ‘\\’ with a single ‘\’ and all ‘\"’ with a ‘"’.

What happens if a pragma ends up in a structure definition or variable initialization? Universal Ctags member masatake commented Feb 3, 2015 @b4n, I agree. Other pragmas are meaningful to the C or C++ compilers. However, GCC does define a few pragmas of its own.

Adding still more breaks it again as soon as the 2048th byte is among the contents of the {-# #-}, so this is indeed an alignment issue. have a peek at these guys Join them; it only takes a minute: Sign up How to automatically insert pragmas in your program up vote 4 down vote favorite I need to write a tool that can Linked 1 How can insert pragmas above some functions in my C code 2 How can I get the function name as text not string in a macro?

For OP's specific task, he'd like write a source to source transform something like the following: rule decorate_function_definition_with_pragma(fh:function_head, b: block): declaration -> declaration = " \fh \b " -> " \fh To enforce this, you can poison the identifier with this pragma. #pragma GCC poison is followed by a list of identifiers to poison. this content Similarly, #pragma GCC error "message" issues an error message.

This lets you poison an identifier without worrying about system headers defining macros that use it. stylish-haskell owner jaspervdj commented Jul 7, 2016 Yes, agreed. If your intention is to automate permanent code changes, ROSE can make this hard: how will it retain comments in the resulting code, if it throws them away as it parses? DMS's C++ flow analysis is limited to control flow at the moment but we're pushing to dataflow; dunno if Rose does any C++ data flow. –Ira Baxter Jun 9 '12 at
