|\ | | | | Added the _Noreturn keyword.
| * Added the _Noreturn keyword.Bernhard Schommer2016-03-238-25/+68
| | | | | | | | | | | | | | | | CompCert now recognizes the C11 _Noreturn function specifier and emits a simple warning for functions declared _Noreturn containing a return statement. Also the stdnoreturn header and additionally the stdalign header are added. Bug 18541
* | Compatibility with newer ocaml versions. Bug 18313.Bernhard Schommer2016-03-312-3/+3

* Fix a bug in the pre-parser.Jacques-Henri Jourdan2016-03-231-0/+1

* Deactivate warning 27 and added back removed code.Bernhard Schommer2016-03-1514-139/+139
| | | | | | The code was mostly there for documentation effort. So warning 27 is deactivated again. Bug 18349
* Upgrade ocaml version needed and enable more warnings.Bernhard Schommer2016-03-101-3/+3
| | | | | | | | | | | Since the menhir version we use requires ocaml>4.02 we can also upgrade the required ocaml version to >4.02 and remove the deprecate String functions. Also we now activate all warnings except for 4,9 und 27 for regular code plus a bunch of warnings for the generated code. 4 and 9 are not really usefull and 27 is deactivated since until the usage string is printed in a way that requires no newline. Bug 18394.
* Code cleanup.Bernhard Schommer2016-03-1016-230/+194
| | | | | | Removed some unused variables, functions etc. and resolved some problems which occur if all warnings except 3,4,9 and 29 are active. Bug 18394.
* Fixed typo in equal types.Bernhard Schommer2016-03-101-1/+1
| | | | | | Compare the underlying array types, otherwise we end up in a endless recursion. Bug 18374
* Make void always incomplete and exit on void members.Bernhard Schommer2016-02-022-2/+8
| | | | | | Since we cannot construct a default initializer for void types we need to exit earlier. Bug 18004.
* Do test for wrap around on singed ocaml integers.Bernhard Schommer2016-01-281-1/+1
| | | | | | In parse_int it was not tested if the value of v is smaller than zero. This allowed it that certain large integers were accepted due to wrap around.
* Allow adding of attributes in valid_assignment_attr.Bernhard Schommer2016-01-281-2/+2
| | | | | Implementing the same behavior as gcc anc clang. Bug 18004
* Enum is compatible to its integer type.Bernhard Schommer2015-12-171-0/+3
| | | | | | The C standard specifies that an enum type should be compatible to some integer type (ISO/IEC 9899:TC3 §6.7.2.2p4). Fix 16692
* More gcc/newlib compatibility code.Bernhard Schommer2015-12-111-1/+8
| | | | | | | | | | Some newlib headers use the __extension__ keyword which suppresses warnings for gcc extensions in strict mode. CompCert now ignores this keyword for the gnu backends. Also it seems that stddef of the gcc defines wint_t even though it should not. However some libs rely on this. So wint_t is now defined in CompCert's stddef header. Bug 17613.
* Revise and simplify the -fstruct-return and -fstruct-passing options.Xavier Leroy2015-12-081-2/+2
| | | | | | - Rename '-fstruct-return' into '-fstruct-passing', because this emulation affects both function result passing and function argument passing. Keep '-fstruct-return' as a deprecated synonymous for '-fstruct-passing' - Remove the ability to change the ABI for struct passing via the '-fstruct-passing=<abi>' and '-fstruct-return=<abi>' command-line flags. This was more confusing than useful. - Produce an error if a struct/union is passed as function argument and '-fstruct-passing' is not set. This used to be supported, using CompCert's default ABI for passing struct arguments. However, this default ABI does not match any of the standard ABIs of our target platforms, so it is better to reject than to silently produce ABI-incompatible code.
* Fixed regression introduce by merge of PR#69.Bernhard Schommer2015-12-031-4/+1
| | | | | | | Since the identifier of a function definition and of its declaration are equal we only should remove functions if the function iteself is removed. Bug 17724.
* Open files in binary mode.Bernhard Schommer2015-11-301-1/+1
| | | | | | On windows opening files in text mode can result in errors due to non-windows compatible input. Thus open files only in binary mode. Bug 17664

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove "&" which was a typo and did not make sense. Use "command -v" instead of "which" (more efficient). Use "=" instead of ":=" (more efficient).
* | | | | Handle large static initializers for global arraysXavier Leroy2015-11-095-5/+5

|/ / / | | | | | | | | | | | | | | | | | | Debug statements introduced during the translation result in warnings when they are introduced at the head of the switch. Since they are not used and the warning is not necessary we can remove them before. Fix 17580.

* | Set [ErrorReports.debug] to [false].François Pottier2015-10-281-1/+1
| | | | | | | | | | | | When [debug] is [false], there are a few places where we silently ignore an error. This should not make any difference if everything works as planned.
