Extending GCC with pragma directive

Hi, May you point me out some sources about writing new #pragma directives in GCC. I looked at the internet for something to start from but unfortunately I could not find anything. Thanks, Ferad Zyulkyarov -- Ferad Zyulkyarov Barcelona Supercomputing Center

Help with traversing block statements in pragma handler

win it will not work.. What I mean is if you have gcc compiled to be hosted in linux it will not work under win and vice versa. For more details you can refer to the configuration documentation of gcc - http://gcc.gnu.org/install/configure.html. Hope it was useful, Ferad Zyulkyarov

Re: Getting declaration tree node using func. name

Re: Creating a variable declaration of custom type.

Hi again, I think that the type of type_node is missing. Try to add TREE_TYPE (type_node); For example TREE_TYPE (type_node) = integer_type_node. (if MyType is int). "MyType" is a struct (of other again coumpound types) and will not work with already existing type nodes like integer_type_node

Re: Creating a variable declaration of custom type.

Getting a tree node for a field of a variable

Re: Getting a tree node for a field of a variable

Re: Getting a tree node for a field of a variable
