* Change the way the debug sections are printed.Bernhard Schommer2015-09-282-67/+50
| | | | | | If a user uses the #pragma use_section for functions the diab linker requires a separate debug_info section for each entry. This commit adds functionality to emulate this behavior.
* Added location for the formal parameters and move the end of allBernhard Schommer2015-09-281-2/+8
| | | | scopes before the last statement.
* Added back again the emitting of the debuging annotations for debugingBernhard Schommer2015-09-271-3/+4
| | | | purpose.
* Added printing the reference address for the LocRef and started refactoring oldBernhard Schommer2015-09-271-12/+0
| | | | | | | | Debuging code. The old functions to store the symbol for the Global variables and retrive this is no longer needed since the atom is stored in DebugInformation. Also the Debug.Abbrev module is no longer needed.
* Added translation of the range lists to location entries.Bernhard Schommer2015-09-251-1/+1
|
* Added support for the locations of stack allocated local variables.Bernhard Schommer2015-09-253-42/+77
| | | | | This commit adds furher support for location information for local variables and starts with the implementation of the debug_loc section.
* Added placing labels for live ranges etc.Bernhard Schommer2015-09-241-6/+103
| | | | | In order to avoid the usage of too many labels we replace the debug statements during the Asmexpand phase.
* Added support for printing local variables and fixed issue with .textBernhard Schommer2015-09-231-3/+6
| | | | | | Local variables are now added with bogus lexical scopes to reflect the actually lexical scopes. Also this commit fixes assembler problems of the das when a user section with the name ".text" is defined.
* Record the scope structure during unblocking.Bernhard Schommer2015-09-221-0/+8
| | | | | | 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.

| * Added builtin for isel.Bernhard Schommer2015-09-085-1/+13
| | | | | | | | | | The builtin_isel function takes a _Bool as first argument and returns either the second or the third depending on the value of the _Bool.
| * Added builtins for call frame and return address.Bernhard Schommer2015-09-076-9/+29
| | | | | | | | | | | | 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.

| * Simplified generation of builtins for cache instructions.Bernhard Schommer2015-09-072-60/+21
| | | | | | | | | | | | The cache instructions need no special constraint on the address argument. Therefore also the generation of the address is no longer needed.
* | First version with computation of dwarf info from debug info.Bernhard Schommer2015-09-171-3/+4
| | | | | | | | | | Introduced a new dwarf generation from the information collected in the DebugInformation and removed the old CtODwarf translation.
* | Revert "Startet implementation of new Debug interface."Bernhard Schommer2015-09-101-3/+2
| | | | | | | | This reverts commit 861292a6c5e58b4f78bef207c717b801b3fc1fed.
* | Startet implementation of new Debug interface.Bernhard Schommer2015-09-061-2/+3
| | | | | | | | | | | | 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.

| * New builtin for dcbz instruction.Bernhard Schommer2015-09-035-24/+33
| | | | | | | | | | | | This commit adds a builtin for the dcbz instructions. Additionally the dcbt,dcbtst,dcbtls and icbtls instruction are changed to their actually form all taking one additional register in Asm.v.

| | | | | | | | | | The dcbtls instruction allows only the values 0 and 2 according to the PPC Isa.

| * Added builtin for dcbtlsBernhard Schommer2015-09-026-13/+63
| | | | | | | | | | | | THis commit adds a builtin function for the dcbtls instruction. Additionaly it changes the printing of the dcbt and dcbtst instruction to embedded mode and adds support for different address variants.
| * Added the gcc builtin prefetch.Bernhard Schommer2015-09-016-0/+25
| | | | | | | | | | | | This commit implements the gcc __builtin_prefetch in a form with all arguments for the powerpc architecture. The resulting instructions are the dcbt and dcbtst instructions in Server Category.

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

| |_|/ |/| | | | | | | | | | | | | | 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.
