* Renamed pedantic to implicit-int.Bernhard Schommer2016-09-223-8/+9
| | | | | | | | The only case where compcert raise a pedantic warning was for implicit int parameters. This is the behavior of clang. However since not all other pedantic warnings are supported the behavior of gcc is adopted. Bug 19872.
* Reverted noisy change.Bernhard Schommer2016-09-221-1/+1
| | | | | | In order to empty declarations it is necessary to distinguish between forward declarations and empty declarations. Bug 19859

| * Fix minor issues in some proofs and tactics.Maxime Dénès2016-09-211-0/+1
| | | | | | | | | | These minor problems were revealed by porting CompCert to Coq 8.6, where they trigger errors.

* | Added conformance warning.Bernhard Schommer2016-08-313-0/+4
| | | | | | | | | | | | This warning should be triggered if a feature is used that is not part of the code CompCert C language. Bug 18004

* | Reworded errors/warnings in Elab.Bernhard Schommer2016-08-311-60/+76
| | | | | | | | | | | | | | | | Some old errors/warnings messages were better before and are now rephrased. Furthermore some formulations are rephrased to match the used formulations of the ISO C stanard, e.g. storage class is replaced with storage-class. Bug 18004

| * | Pass the environment of k&r param elaboration.Bernhard Schommer2016-08-291-8/+10
| | | | | | | | | | | | | | | | | | The environment where the types are inserted is passed back to allow introducing structs in k&r parameters. Bug 19668

| * | Use old scope in after parameter parsing.Bernhard Schommer2016-08-261-1/+1
| | | | | | | | | | | | | | | | | | Not decrementing the scopes again after a parameter parsing lead to other scoping problems. Bug 19656.
| * | Reuse types from parameters in function definitonsBernhard Schommer2016-08-253-41/+47
| | | | | | | | | | | | | | | | | | In order to allow introducing structs in parameter definitions the environment must keep the type information. Bug 19602

| | | | | | | | | | | | | | | | | | If a declaration of a composite is encountered it is also tested if the kind is equal. Bug 19630.

| | * | | Implement support for big endian arm targets.Bernhard Schommer2016-08-052-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds support for the big endian arm targets by making the target endianess flag configurable, adding support for the big endian calling conventions, rewriting memory access patterns and adding big endian versions of the runtime functions.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since some incomplete types are allowed in initialization just test whether the default initilization exists. Bug 19601

| | | | | | | | | | | | | | | | | | | | | Instead of a warning for an empty union CompCert reports an error and exits. This avoids problems during the generation of initializers for these. Bug 19565.

|/ | | | | | | | | | Now each warning either has a name and can be turned on/off, made into an error,etc. or is a warning that always will be triggered. The message of the warnings are similar to the ones emited by gcc/clang and all fit into one line. Furthermore the diagnostics are now colored if colored output is available. Bug 18004
