Hello, I am still dreaming of a fast way of inline assembly code for fast addition of 64 bit variables with saturation control. (I need to write 0x7FFFFFF... to the result register, if overflow occurred).
For this purpose it would be necessary to access the BVS and BCS flags directly after addition of 2 register pairs in in line assembly (using conditional code / jump marks).
As compiler version is meanwhile 5 and I have lost a bit the survey on all the enhancements, has any one perhaps a proposal for this?
(In older versions it did not work, because first Thumb code was not allowed in inline assembly. This meanwhile seems to work, but I am frightened it is still not possible to use any sort of conditional statements within the inline assembly, is this correct?)
