* TBAA: handle scalar TBAA format and struct-path aware TBAA format.Manman Ren2013-09-271-2/+2
| | | | | | | | | | | | | | | | | Remove the command line argument "struct-path-tbaa" since we should not depend on command line argument to decide which format the IR file is using. Instead, we check the first operand of the tbaa tag node, if it is a MDNode, we treat it as struct-path aware TBAA format, otherwise, we treat it as scalar TBAA format. When clang starts to use struct-path aware TBAA format no matter whether struct-path-tbaa is no, and we can auto-upgrade existing bc files, the support for scalar TBAA format can be dropped. Existing testing cases are updated to use the struct-path aware TBAA format. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191538 91177308-0d34-0410-b5e6-96231b3b80d8

* Make jump threading substantially more powerful, in the following ways:Chris Lattner2008-11-271-0/+34
1. Make it fold blocks separated by an unconditional branch. This enables jump threading to see a broader scope. 2. Make jump threading able to eliminate locally redundant loads when they feed the branch condition of a block. This frequently occurs due to reg2mem running. 3. Make jump threading able to eliminate *partially redundant* loads when they feed the branch condition of a block. This is common in code with lots of loads and stores like C++ code and 255.vortex. This implements thread-loads.ll and rdar://6402033. Per the fixme's, several pieces of this should be moved into Transforms/Utils. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60148 91177308-0d34-0410-b5e6-96231b3b80d8
