| I cannot find in this patch where you add TARGET_ALLEGREX for ISA_HAS_ROR. |

...you scared me. i've just thought i really missed that and need to go through all the build process again. :-)

lol ! I just looked at the patch not at the result so i couldn't see it ;P. Well, globally this patch appears good.
I guess what it lacks is vfpu now. |

If you mean compiler intrinsics for VFPU like that is done for, say, SSE or AltiVec, then it's a damn load of work... I'm not sure even where to start.
But that'd be very nice to have, surely.

i don't think intrinsics (the biggest load of works, yes) are important. The only thing important is for gcc to be able to allocate vfpu registers in asm statements and for function arguments or results. With this minimal requirement, you can let gcc optimize through inline functions using allocation of those registers and asm statements. I already did that for psp-gcc 4.0, but i still had some troubles to mix vfpu scalar float and fpu float (i was forced to exclude one of both from arguments) and things like that.
I should probably retry it cleaner.
But I'm still not decided with which version to apply those changes : 2.1.0 or 2.3.0 ? |

I think 4.3.0 will be better. :-)

Fixed top message for truth. © :-)
UPD: I experience major slowdown when working with this version... For some reason it chews the disk for a few seconds and only then does the work... And that for each file being compiled. I'm not sure whether this is my cygwin installation's broken or the compiler is insane.
What about you?

getting the code to compile and link correctly is already a win to me. :-)
but indeed, we need some kind of a testbench. i'm not sure whether built-in testsuite will do since it's a cross-compiler we build.
