--- Comment #6 from Roland Illig <roland.illig at gmx dot de> --- (In reply to Maciej W. Rozycki from comment #4) > The flag enables the use of the conditional-move operations even with > hardware that has no support for such operations, hence unconditionally. Thank you for your explanation, that made the intention much clearer to me. There's a problem with the wording though. On a platform that doesn't support conditional-move operations, it's not possible to _use_ conditional-move operations. Period. It's only possible to _emulate_ the behavior of these operations. I'm not sure how consistently the words 'operation' and 'instruction' are used in the GCC code base and documentation, but I mixed them up in my mind when I tried to translate this option. > if someone has > a better proposal, then please feel free to submit a patch. Or would: > > Enable conditional-move operations unconditionally. > > be preferable? No. Above, you wrote that the branchless instructions would be selected _if_ they are cheaper than the equivalent branch instructions. This is a condition, thus the word 'unconditionally' doesn't fit. What about this? > Prefer branchless move instructions where cheaper.
