| * | | | | | Added builtin for atomic compare and exchange.Bernhard Schommer2015-09-104-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new __builtin_atomic_compare_exchange(int *ptr,int *exp,int *dsr); writes dsr into ptr if ptr is equal to exp and returns true if ptr is not equal to exp it writes ptr into exp and returns false.

| * | | | | | | Add builtin for atomic load.Bernhard Schommer2015-09-092-1/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement the new __builtin_atomic_load(int *a, int *b); which stores *a in *b. This differs from the atomic_load of the GCC, since the PPC ISA manual states that you must jump before the load again if it fails.
| * | | | | | | Added an builtin for the atomic exchange operation.Bernhard Schommer2015-09-095-7/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new builtin __builtin_atomic_exchange(int *a, int *b, int *c) stores *b in *a and sets *c to the old value of *a.

* | | | | | | Issue with ignoring the result of non-void builtin functions.Xavier Leroy2015-09-156-15/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In RTL and beyond, the result of a builtin function that has return type different from "void" must be BR, never BR_none. Otherwise, we get compile-time fatal errors, either in Asmexpand or in Lineartyping.

| | | | | | | | | | | | | | | | | | | | | | | | This builtins can be used to get the call frame address and the return address. To correctly compute the load address of the return address the allocframe is extended to contain the offset of the return address.

| | | | | | | | | | | | | | | | | | | | | | | | The debug printer now uses udata for member sizes since structs can have a size larger than 255 bytes. Also functions that are inlined no longer have an high and low pc in their abbreviation entry.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.
