New Revision: 133105
URL: http://llvm.org/viewvc/llvm-project?rev=133105&view=rev
Log:
Use set operations instead of plain lists to enumerate register classes.
This simplifies many of the target description files since it is common
for register classes to be related or contain sequences of numbered
registers.
I have verified that this doesn't change the files generated by TableGen
for ARM and X86. It alters the allocation order of MBlaze GPR and Mips
FGR32 registers, but I believe the change is benign.
