search for: copro

hi all, I am attempting to install centos 4.4 on an ebox 2300sx. I start with "i586 text" everything starts up and then I get: No coprocessor found and no math emulation present. How do I get math emulation? THanks Jerry

It's my impression that most DSPs have such "snazzy" addressing modes ;-) > I assume that you're planning on only > targetting the RISC core and not the vector copro? Right. It would be experemely hard to generate efficient code for the vector unit. - Volodya

...ot the standard > compiler. Ohhh, sounds great. From a brief look through their data sheets, it looks like it's a pretty RISCy processor, but has some snazzy addressing modes with pre/post in/decrements. I assume that you're planning on only targetting the RISC core and not the vector copro? -Chris -- http://llvm.cs.uiuc.edu/ http://www.nondot.org/~sabre/Projects/

...AArch64 system register and a AArch32 cp register. To try and reduce ifdeferry in common code I''ve introduced some macros which take the AArch64 name but which translate to the appropriate AArch32 cpreg access in the 32-bit hypervisor. A little bit of ifdeferry remains. Other uses of the coprocessors (e.g. cache/TLB flushing etc) are replaced with explicit instructions (again there''s mostly a 1-1 mapping). We had already wrapped most of these in a suitable inline function so it was easy enough to abstract away. Lastly, rather than switch internally from explicitly sized types t...

This round implements all of the review comments from V2 and all patches are now acked. Unless there are any objections I intend to apply later this morning. Ian.
