...ELECT_CC and BR_CC in the usual way, mostly following the ARM implementation. In particular the target cmp instruction is created and glued to a target conditional instruction, such as a conditional branch, or a conditional select. The generated code may look like this: add R0, R1, R2 cmp R0, #0 breq Label This works fine, but now I would want to go one step further: As part of the SETCC and SELECT_CC lowering, I can determine if the conditions are met in my architecture to avoid generating a ‘cmp’ instruction at all. For example, if the left operand of the SETCC is an ‘addition', the rig...

Hello The current crypto_engine support only ahash and ablkcipher. My first patch which try to add skcipher was Nacked, it will add too many functions and adding other algs(aead, asymetric_key) will make the situation worst. This patchset remove all algs specific stuff and now only process generic crypto_async_request. The requests handler function pointer are now moved out of struct engine and
