| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SimplLocals: - record locations of stack-allocated variables with annotations (of kind 5) at the beginning of the function; - mark every assignment to non-stack-allocated variables with an annotation of kind 2. Debugvar: (new pass!) - perform availability analysis for debug annotations of kind 2 - insert "start of live range" and "end of live range" annotations (kind 3 and 4) to delimit intervals of PCs where the location of a local variable is known. | |||||

| | | | | | | | | | | | | | | | | | | | | | | | | Use EF_debug instead of EF_annot for line number annotations. Introduce PrintAsmaux.print_debug_info (very incomplete). powerpc/Asmexpand: revise expand_memcpy_small. | |||||

| | | | | | | | | | | | | | | | | | | | | | __builtin_get_spr() and __builtin_set_spr() work, but horrible error message if the SPR argument is not a constant. powerpc/AsmToJSON.ml needs updating. | |||||

| | * | | Refactoring of builtins and annotations in the back-end. | Xavier Leroy | 2015-08-21 | 64 | -2044/+2181 | |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. | |||||

| | | | | | | | | | | | | | | | | | | | | | | | | operations with undefined behaviors. Consider (x ^ 1) ^ 1 where x is a intptr_t containing a pointer value. "x ^ 1" evaluates to Vundef in the CompCert semantics, hence the value analysis, in strict mode, gives abstract result Ifptr Pbot (= any number but not a pointer). In relaxed mode, we now give abstract result Ifptr (poffset p) where p is the abstraction of the pointer, thus keeping track of the actual leak of the pointer value. | |||||
