...e: Your patch is similar to what I'd coded (and am testing, which means a couple of hours before I consider committing). Other than cosmetic changes and changing 'NULL' to '0' (it's an integer list, after all). This patch now causes new problems in the CellSPU backend (more stqd's and lqd's), so I have to investigate those before committing the patch. 'make test' is our friend. 'make test' is our friend. 'make test' is our friend. :-) -scooter On Thu, Feb 25, 2010 at 11:25 PM, <Kalle.Raiskila at nokia.com> wrote: > > Scott M...

No, I wasn't having a management lobotomy moment. If the target's registers have no subregisters, SubUsed is false and the assert gets tripped. Ok, back to the original question: What was the original intent in this code (lines 186-193 in lib/CodeGen/RegisterScavenging.cpp)? -scooter On Thu, Feb 25, 2010 at 7:00 PM, Scott Michel <scooter.phd at gmail.com> wrote: > Ugh.
