Ehsan Amiri	a538b0f023	Adding -verify-machineinstrs option to PowerPC tests ... Currently we have a number of tests that fail with -verify-machineinstrs. To detect this cases earlier we add the option to the testcases with the exception of tests that will currently fail with this option. PR 27456 keeps track of this failures.

Evan Cheng	44c0b4f754	Fix live variables issues: ... 1. If part of a register is re-defined, an implicit kill and an implicit def are added to denote read / mod / write. However, this should only be necessary if the register is actually read later. This is a performance issue. 2. If a sub-register is being defined, and it doesn't have a previous use, do not add a implicit kill to the last use of a super-register: = EAX, AX<imp-use,kill> ... AX = In this case, EAX is live but AX is killed, this is wrong and will cause the coalescer to do bad things. llvm-svn: 48521	2008-03-19 00:52:20 +00:00
