| | * Continuing experiment: track the scopes of local variables via __builtin_debugXavier Leroy2015-09-212-39/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As observed by B. Schommer, it is not enough to track scopes for every source line, as blocks can occur on a single line (think macros). Hence: - Revert debug annotations of kind 1 to contain only line number info. Generate them only when the line number changes. - Use debug annotations of kind 6 to record the list of active scopes (as BA_int integer arguments to __builtin_annot). Generate them before every nontrivial statement, even if on the same line as others. - Remove the generation of "variable x is declared in scope N" debug annotations. This can be tracked separately and more efficiently.
| * | Record the scope structure during unblocking.Bernhard Schommer2015-09-2214-65/+173
| | | | | | | | | | | | | | | | | | Instead of creating separate annotations for the local variables we call the Debug.add_lvar_scope and we construct a mapping from function id + scope id to scope information.

| | * Experiment: track the scopes of local variables via __builtin_debug.Xavier Leroy2015-09-205-74/+181
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | C2C: the code that insert debug builtins with the line numbers is now in Unblock. Handle calls to __builtin_debug. Unblock: generate __builtin_debug(1) for line numbers, carrying the list of active scopes as extra arguments. Generate __builtin_debug(6) for local variable declarations, carrying the corresponding scope number as extra argument. Constprop: avoid duplicating debug arguments that are constants already. PrintAsmaux: show this extra debug info as comments.
| * | New version of adding scopes etc.Bernhard Schommer2015-09-204-16/+63
| | | | | | | | | | | | | | | Instead of reimplementing the whole scope handling in the debug information use the existing functionality and fill the scopes explicitly in the functions.
| * | Started implementing the scope for the Debug Informations.Bernhard Schommer2015-09-186-13/+109
| | | | | | | | | | | | | | | | | | Scopes will be handled by a stack of all open scopes. This stack then can also be used to generate the debug directives to track the scopes through the rest of the passes.
| * | First version with computation of dwarf info from debug info.Bernhard Schommer2015-09-1714-636/+370
| | | | | | | | | | | | | | | Introduced a new dwarf generation from the information collected in the DebugInformation and removed the old CtODwarf translation.
| * | Move more functionality in the new interface.Bernhard Schommer2015-09-1615-75/+120
| | | | | | | | | | | | | | | | | | Added functions to add more information to the debuging interface, like the struct layout with offsets, bitifiled layout and removed the no longer needed mapping from stamp to atom.
| * | Add the debug interface file.Bernhard Schommer2015-09-165-12/+177
| | | | | | | | | | | | | | | | | | | | | | | | The new file Debug.ml contains the interface for generating and printing debug information. In order to generate debug information the init function initializes the necessary functions depending on the -g flag. If the -g is not there all functions are dummy functions which do nothing.
| * | Further function to add debug information.Bernhard Schommer2015-09-151-31/+67
| | | | | | | | | | | | | | | Added the rest of the global declarations and started adding functions to fill in the missing information about struct and union fields etc.

| * | Implemented insert_type function and started implementing add declaration.Bernhard Schommer2015-09-141-13/+206
| | | | | | | | | | | | | | | | | | The insert_type function add types by adding their subtypes. Also currently the structs or unions are added as empty skeletopn and later during filled during the inserting of the declarations.
| * | Started implementing the typ insert methods.Bernhard Schommer2015-09-112-50/+99
| | | | | | | | | | | | | | | | | | In contrast to CtoDwarf this time we use the name to identify everything. To make this work we print the full identifier with stamp to avoid the problems with anonymous structs and unions.

| | | | | | | | | | | | | | | | | | Added a new file debug/Debug.ml which will be the interface between for generating and printing the debuging information. Currently it contains only the code for the line directived.

| * | | | | Removed usage of bne and removed duplicated code for return values of atomics.Bernhard Schommer2015-09-154-52/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of introducing a new bne instruction in Asm.v and the TargetPrinter.ml I use the equivalent bf instruction. The duplicated code is due to unused return values of builtins. Now we only emit the additional code for the return value if the return value is used instead of duplicating the whole emiting sequence.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to avoid clashes during register allocation etc. The builtins now use fixed registers and mark additional registers as destroyed for temporaries.

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

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

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