2015-03-13tcg: Change translator-side labels to a pointerRichard Henderson
This is improved type checking for the translators -- it's no longer possible to accidentally swap arguments to the branch functions. Note that the code generating backends still manipulate labels as int. With notable exceptions, the scope of the change is just a few lines for each target, so it's not worth building extra machinery to do this change in per-target increments.

2015-01-26target-tricore: split up suov32 into suov32_pos and suov32_negBastian Koppelmann
suov checks unsigned for an overflow and an underflow, after some arithmetic operations and saturates the result to either max_uint32 or 0. So far we handled this by expanding to the next bigger data type and compare whether the result is > max_uint32 or < 0. However this approach can fail for an 32 bit multiplication, if both operands of the multiplication are 0x80000000. This sets the sign bit of the 64 bit integer and would result in a false saturation to 0. Since unsigned operations, e.g add, sub, mul always result in either a positive or negative overflow, we split the functions for suov32 up into two functions (suov32_pos, suov32_neg) for each case.
