What is register scavenging?
Hi, I would like to know what register scavenging is, but reading RegisterScavenging.h [1] and googling don't help too much. Could someone explain it a little bit (what it is and when we need it), or point me to some nice link, I will be very appreciated. :-) [1] http://llvm.org/docs/doxygen/html/RegisterScavenging_8h_source.html Regards, chenwj -- Wei-Ren Chen (陳韋任) Homepage:
