...s of usedPregSet. The attached Gcra includes code for this. It also moves the erasure of the subreg index out of the inner loop so that if a vreg appears multiple times in an instruction all subreg indexes will be cleared. - Lang.

...class as 'vreg'. The update adds a new variable, preg_op, to hold the subregister of preg that will be used for the operand currently being rewritten, and preg_op will be set to a subreg of preg where appropriate. - Lang.

My tst.bc is attached. I had to use ssh to copy it from my office machine to my home laptop. In case that corrupts it, I also put a copy here: http://pages.cs.wisc.edu/~horwitz/LANG/tst.bc I created the file like this: clang -emit-llvm -O0 -c tst.c -o tst.bc opt -mem2reg tst.bc > tst.mem2reg mv tst.mem2reg tst.bc Susan On 11/4/2012 3:27 PM, Lang Hames wrote: > Hi Susan, > > I tested the version of Gcra.cpp that I sent you on x86-64 systems &...

...lCodeGenComponents.h. (If you search for createRegAllocPBQP you'll see where to add the declarations). With that setup, running your allocator on the tst.c file you attached previously yielded a sane assembly file. Cheers, Lang.
