* | | Merge pull request #43 from AbsInt/standard-headers | Xavier Leroy | 2015-06-08 | 11 | -13/+339 | |
|\ \ | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. | |||||

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Leroy | 2015-06-07 | 2 | -2/+2 | |
| | | | | | | | | | | | | 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. | |||||

* | | | Ctyping: better typing of conditional expressions. | Xavier Leroy | 2015-05-21 | 4 | -52/+202 | |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ctyping: define a typechecker for whole programs. Csyntax: introduce the type "pre-program" (non-dependent). C2C: use Ctyping.econdition instead of Ctyping.econdition'. Note: Ctyping.typecheck_program could be used as the first step in the verified compilation pipeline. Then, retyping would no longer be performed in C2C. We keep it this way (for the time being) because retyping errors are reported more precisely in C2C than in Ctyping. | |||||

* | | | Extended inline asm: revised treatment of clobbered registers. | Xavier Leroy | 2015-05-09 | 17 | -110/+147 | |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Treat clobbered registers as being destroyed by EF_inline_asm builtins (which is the truth, semantically). - To enable the above, represent clobbers as Coq strings rather than idents and move register_by_name from Machregsaux.ml to Machregs.v. - Side benefit: more efficient implementation of Machregsaux.name_of_register. -# Please enter the commit message for your changes.

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GCC-style extended inline asm. The subset implemented is: - zero or one output - output constraints "=r" (to register) or "=m" (to memory) - zero, one or several inputs - input constraints "r" (in register), "m" (in memory), "i" and "n" (compile-time integer constant) - clobbered registers (the 3rd argument) - both anonymous (%3) and named (%[name]) operands - modifiers %R and %Q to refer to the most significant / least significant part of a register pair holding a 64-bit integer. (Undocumented GCC ARM feature.) All asm statements are treated as "volatile", possibly modifying memory and condition codes. | |||||
