* New builtin for dcbz instruction.Bernhard Schommer2015-09-031-0/+2
| | | | | | 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.
* Added builtin for the icbtls instruction.Bernhard Schommer2015-09-021-0/+2
| | | | This commit adds a builtin for the icbtls instruction.
* Added builtin for dcbtlsBernhard Schommer2015-09-021-0/+2
| | | | | | 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 Schommer2015-09-011-0/+2
| | | | | | 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.
* Adapt the PowerPC port to the new builtin representation.Xavier Leroy2015-08-211-1/+6
| | | | | | | __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.
