2010-10-19Shrink MachineOperand from 40 to 32 bytes on 64-bit hosts.Jakob Stoklund Olesen
Pull an unsigned out of the Contents union such that it has the same size as two pointers and no padding. Arrange members such that the Contents union and all pointers can be 8-byte aligned without padding. This speeds up code generation by 0.8% on a 64-bit host. 32-bit hosts should be unaffected. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@116857 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-19Change AliasAnalysis and its clients to use uint64_t instead of unsignedDan Gohman
for representing object sizes, for consistency with other parts of LLVM. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@116831 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-19Get rid of static constructors for pass registration. Instead, every pass ↵Owen Anderson
exposes an initializeMyPassFunction(), which must be called in the pass's constructor. This function uses static dependency declarations to recursively initialize the pass's dependencies. Clients that only create passes through the createFooPass() APIs will require no changes. Clients that want to use the CommandLine options for passes will need to manually call the appropriate initialization functions in PassInitialization.h before parsing commandline arguments. I have tested this with all standard configurations of clang and llvm-gcc on Darwin. It is possible that there are problems with the static dependencies that will only be visible with non-standard options. If you encounter any crash in pass registration/creation, please send the testcase to me directly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@116820 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-19- Add a hook for target to determine whether an instruction def isEvan Cheng
"long latency" enough to hoist even if it may increase spilling. Reloading a value from spill slot is often cheaper than performing an expensive computation in the loop. For X86, that means machine LICM will hoist SQRT, DIV, etc. ARM will be somewhat aggressive with VFP and NEON instructions. - Enable register pressure aware machine LICM by default. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@116781 91177308-0d34-0410-b5e6-96231b3b80d8
