| * Merge pull request #43 from AbsInt/standard-headersXavier Leroy2015-06-083-2/+9
| |\ | | | | | | | | | | | | | | | | | | | | | | | | | | | Merge of the "standard-headers" branch. This provides CompCert-compatible implementations of the following standard headers: float.h, stdarg.h, stdbool.h, stddef.h, varargs.h. These are the headers that are provided by GCC, Clang, and TCC. Other standard headers are provided by Glibc and similar C standard libraries. So far in CompCert we rely on the headers provided by whatever C compiler is installed on the host platform. This causes some difficulties that this branch addresses: 1- Diab C's stdarg.h is not compatible with CompCert 2- On IA32 and PowerPC, CompCert's "long double" type differs from the "long double" type specified by the ABI. Hence, the platform's float.h gives "long double" parameters that do not match CompCert.
| | * Provide and use compiler-dependent standard headers.Xavier Leroy2015-04-253-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This branch provides implementations of the following standard headers: <float.h> <stdarg.h> <stdbool.h> <stddef.h> <varargs.h> These are the headers that are provided by GCC and Clang, as opposed to being provided by Glibc and similar C standard libraries. Configuration flag "-no-standard-headers" deactivates the installation and use of these headers. Lightly tested so far (IA32 Linux).
| * | Represent external worlds by a coinductive type rather than an inductive type.Xavier Leroy2015-06-071-1/+1
| | | | | | | | | | | | As noticed by R. Krebbers, an inductive type for external worlds implies that all sequences of program-world interactions are finite, which is not the case.

| * | ABI compatibility for struct/union function arguments passed by value.Xavier Leroy2015-01-272-1/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The passing of struct/union arguments by value implemented in the verified part of CompCert is not compatible with the ARM, PowerPC and x86 ABI. Here we enrich the StructReturn source-to-source emulation pass so that it implements the calling conventions defined in these ABIs. Plus: for x86, implement the returning of struct/union results by value in a way compatible with the ABI.

* Revised translation of '&&' and '||' to Clight.Xavier Leroy2014-10-131-1/+1
| | | | | | | | | | | The previous translation (in SimplExpr) produced references to the same temporary variable with two different types (bool and int), which is not nice if we want to typecheck the generated Clight. The new translation avoids this and also gets rid of the double cast to bool then to int. The trick is to change Eparen (in CompCert C expressions) to take two types: the type to which the argument must be converted, and the type with which the resulting expression is seen.
