* Keep track of the call instructions whose clobber lists were skipped during fastJakob Stoklund Olesen2010-06-041-0/+17
* Add support for partial redefs to the fast register allocator.Jakob Stoklund Olesen2010-05-191-20/+18
* Properly handle multiple definitions of a virtual register in the sameJakob Stoklund Olesen2010-05-181-21/+41

* Extract spill cost calculation to a new method, and use definePhysReg() to clearJakob Stoklund Olesen2010-05-171-86/+64
* Only use clairvoyance when defining a register, and then only if it has one use.Jakob Stoklund Olesen2010-05-171-16/+11
* Eliminate a hash table probe when killing virtual registers.Jakob Stoklund Olesen2010-05-171-15/+20
* Execute virtreg kills immediately instead of after processing all uses.Jakob Stoklund Olesen2010-05-171-19/+16
* Sprinkle superregister <imp-def> and <imp-kill> operands when dealing with su...Jakob Stoklund Olesen2010-05-171-10/+28
* Now that we don't keep live registers across calls, there is not reason to goJakob Stoklund Olesen2010-05-171-7/+12

* Don't bother spilling before a returnJakob Stoklund Olesen2010-05-141-4/+13
* Track allocatable instead of reserved regs, and never take an unallocatable h...Jakob Stoklund Olesen2010-05-141-8/+10
* Avoid scanning the long tail of physreg operands on callsJakob Stoklund Olesen2010-05-141-4/+9
* Count coalesced copiesJakob Stoklund Olesen2010-05-141-0/+2
* Allow virtreg redefines when verifying for RegAllocFastJakob Stoklund Olesen2010-05-141-1/+1
* When verifying two-address instructions, check the following:Jakob Stoklund Olesen2010-05-141-0/+5

* More asserts around physreg usesJakob Stoklund Olesen2010-05-131-1/+11
* Make sure to add kill flags to the last use of a virtreg when it is redefined.Jakob Stoklund Olesen2010-05-121-12/+22
* Avoid scoping issues, fix buildbotsJakob Stoklund Olesen2010-05-121-20/+21
* Make Clang happy.Daniel Dunbar2010-05-111-3/+3
* Store the Dirty bit in the LiveReg structure instead of a bit vector.Jakob Stoklund Olesen2010-05-111-34/+28
* Keep track of the last place a live virtreg was used.Jakob Stoklund Olesen2010-05-111-72/+118
