* | Refactoring of builtins and annotations in the back-end. | Xavier Leroy | 2015-08-21 | 1 | -118/+176 |
| | | | | | | | | | | | | | | | | | | | | | | | | Before, the back-end languages had distinct instructions - Iannot for annotations, taking structured expressions (annot_arg) as arguments, and producing no results' - Ibuiltin for other builtins, using simple pseudoregs/locations/registers as arguments and results. This branch enriches Ibuiltin instructions so that they take structured expressions (builtin_arg and builtin_res) as arguments and results. This way, - Annotations fit the general pattern of builtin functions, so Iannot instructions are removed. - EF_vload_global and EF_vstore_global become useless, as the same optimization can be achieved by EF_vload/vstore taking a structured argument of the "address of global" kind. - Better code can be generated for builtin_memcpy between stack locations, or volatile accesses to stack locations. Finally, this commit also introduces a new kind of external function, EF_debug, which is like EF_annot but produces no observable events. It will be used later to transport debug info through the back-end, without preventing optimizations. | ||||
* | Extend annotations so that they can keep track of global variables and local ↵ | Xavier Leroy | 2015-03-27 | 1 | -28/+81 |

Implementation is not complete yet. | ||||
* | Add Genv.public_symbol operation. | Xavier Leroy | 2014-11-24 | 1 | -10/+18 |
| | | | | | Restrict pointer event values to public global names. Update proofs accordingly. PowerPC and ARM need updating. | ||||
* | Updated ARM backend wrt new static analyses and optimizations. | xleroy | 2014-01-02 | 1 | -83/+93 |
| | | | | | | | | NeedOp, Deadcode: must have distinct needs per argument of an operator. This change remains to be propagated to IA32 and PPC. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2399 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e | ||||
