Abstract syntax tree
Types in this module represent various pieces a C program can contain after preprocessing phase. They mostly follow C11 grammar naming conventions.
References to C11 standard given in parenthesis refer to the ISO/IEC 9899:201x draft published on April 12, 2011.
A number of GNU extensions to the standard C are included here. Types, struct fields or enum variants specific to GNU are marked as “GNU extension” with a link to the relevant section of gcc documentation. Supported extensions are:
- attributes in various positions
- inline assembly statements and asm labels
- extensions to the initializer list syntax
- statement expressions
