* c_parser: support parenthesized compounds (#423)Jordan Yates2021-07-071-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * c_parser: support parenthesized compounds Support parenthesized compound statements as described here: https://gcc.gnu.org/onlinedocs/gcc/Statement-Exprs.html Signed-off-by: Jordan Yates <jordan.yates@data61.csiro.au> * test_c_parser: support additional initializers Add support to `expand_init` for additional `c_ast` types. If a type is not explicitly handled, return the type name instead of `None`. Signed-off-by: Jordan Yates <jordan.yates@data61.csiro.au> * test_c_parser: test parenthesized compounds Add parsing tests for various situations of parenthesized compound statements. The complete tree generated by the test string is: ``` FileAST: FuncDef: Decl: foo, [], [], [] FuncDecl: TypeDecl: foo, [] IdentifierType: ['void'] Compound: Decl: a, [], [], [] TypeDecl: a, [] IdentifierType: ['int'] Compound: Compound: Constant: int, 1 Compound: Constant: int, 1 Constant: int, 2 Decl: b, [], [], [] TypeDecl: b, [] IdentifierType: ['int'] Compound: Constant: int, 1 Decl: c, [], [], [] TypeDecl: c, [] IdentifierType: ['int'] Decl: d, [], [], [] TypeDecl: d, [] IdentifierType: ['int'] Compound: Decl: x, [], [], [] TypeDecl: x, [] IdentifierType: ['int'] Constant: int, 1 BinaryOp: + ID: x Constant: int, 2 Assignment: = ID: a Compound: Decl: x, [], [], [] TypeDecl: x, [] IdentifierType: ['int'] Constant: int, 1 BinaryOp: * Constant: int, 2 ID: x ``` Signed-off-by: Jordan Yates <jordan.yates@data61.csiro.au>
* Added flattening of abundant parenthesis in CGenerator (#394)Julian2020-10-051-0/+1

* Fix issues #378, #379, #385 (#387)Zecong Hu2020-07-181-5/+7
| | | | | | | | | | | | * Fix #385: generate code with nested sizeofs * Fix #378: replace assertion with check Only the assertion inside `_build_function_definition` is replaced. The assertion is not appropriate because there are possible inputs that would trigger the assertion, they're just grammatically incorrect. Thus, it is replaced with a check that raises `ParseError` on failure. * Fix #379: parse struct with nested enum
* Fix #363 incorrect AST when parsing offsetof (#364)Zecong Hu2020-03-031-2/+1

* Recognize integer multicharacter constants like 'ABCD' (#350)yaroslav-o2019-09-251-0/+1
| | | | | | | | | | | | | Recognize integer multicharacter constants like 'ABCD' The feature I am adding is defined here - 5th case. https://en.cppreference.com/w/c/language/character_constant Also here: 6.4.4.4.10 of C99. Put simply, pycparser thought a statement like this is an error: int a = 'ABCD'; However it is not. It is likely possible to just modify char_const regular expression in c_lexer.py:240 to allow longer characters, but the way it is done in this PR - multicharacter constants are clearly separated. I am also limiting the length of multicharacter const integers to 4 characters - this matches VS compiler behavior (gcc allows any length with a warning) and lets pycparser NOT consider lengthy single-quoted strings as integers - these would be nonsensical anyway.

* Correct Parsing of Floating Point Literals, issue #253 (#277)Robbert Harms2018-08-311-1/+11
| | | | | | * Corrects the type attribute of a constant node when parsing doubles. This sets the type attribute to either 'float', 'long double' or 'double' depending on if 'f|F', 'l|L' or '' is specified at the end of the constant definition. * Add tests for previous changes.

* Add support for #pragmaJulian Hammer2015-10-201-2/+13
| | | | | | | | | | | | Preprocessor pragmas and their arguments are tokenized (as PPPRAGMA and PPPRAGMASTR) and included in the AST as a pppragma directive with the argument as value. If no argument was given the string will be empty. Unit test of the lexer, parser and generator have been modified and added accordingly. The previous behavior, that #pragma lines would be ignored, is henceforth obsolete.
