Jakob Stoklund Olesen ead06be02f Use readsWritesVirtualRegister instead of counting uses and defs when inserting ... spills and reloads. This means that a partial define of a register causes a reload so the other parts of the register are preserved. The reload can be prevented by adding an <imp-def> operand for the full register. This is already done by the coalescer and live interval analysis where relevant. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@105369 91177308-0d34-0410-b5e6-96231b3b80d8		2010-06-03 00:07:47 +00:00

Analysis	Fix the noalias checking so that it doesn't worry about	2010-06-01 20:51:40 +00:00
Archive	Eliminate some unnessary Path::exists() calls.	2010-05-27 20:51:54 +00:00
AsmParser	Eliminate the restriction that the array size in an alloca must be i32.	2010-05-28 01:14:11 +00:00
Bitcode	Speedup bitcode writer. Do not walk all values for all functions to emit function local metadata. In one testcase, probably worst case scenario, the 70x speed up is seen.	2010-06-02 23:05:04 +00:00
