* Add a couple more heuristics to neuter machine cse some more.Evan Cheng2010-03-101-13/+57
| | | | | | | | | | | 1. Be careful with cse "cheap" expressions. e.g. constant materialization. Only cse them when the common expression is local or in a direct predecessor. We don't want cse of cheap instruction causing other expressions to be spilled. 2. Watch out for the case where the expression doesn't itself uses a virtual register. e.g. lea of frame object. If the common expression itself is used by copies (common for passing addresses to function calls), don't perform the cse. Since these expressions do not use a register, it creates a live range but doesn't close any, we want to be very careful with increasing register pressure. Note these are heuristics so machine cse doesn't make register allocator unhappy. Once we have proper live range splitting and re-materialization support in place, these should be evaluated again. Now machine cse is almost always a win on llvm nightly tests on x86 and x86_64. llvm-svn: 98121

* Try to keep the cached inliner costs around for a bit longer for big functions.Jakob Stoklund Olesen2010-03-096-6/+63
| | | | | | | | | | | | | | | The Caller cost info would be reset everytime a callee was inlined. If the caller has lots of calls and there is some mutual recursion going on, the caller cost info could be calculated many times. This patch reduces inliner runtime from 240s to 0.5s for a function with 20000 small function calls. This is a more conservative version of r98089 that doesn't break the clang test CodeGenCXX/temp-order.cpp. That test relies on rather extreme inlining for constant folding. llvm-svn: 98099

* The ARM EH experiment worked!Bill Wendling2010-03-094-50/+78
| | | | | | | | | | | | Place the LSDA into the TEXT section for ARM platforms. This involves making the encoding indirect, pcrel, and sdata4 instead of an absolute pointer. The references to the type infos are then non-lazy pointers. Revision 98019 changed the encoding of non-lazy pointers to add the symbol to the non-lazy pointer definition if it's a local symbol (otherwise, it's external and set to '0' so that the loader can adjust it to the real value). This paved the way for this change to work on ARM. llvm-svn: 98068
