* Teach getCastOpcode about element-by-element vector casts. For example, "trunc"Duncan Sands2011-05-181-0/+8
| | | | | | | | | | | | | | can be used to turn a <4 x i64> into a <4 x i32> but getCastOpcode would assert if you passed these types to it. Note that this strictly extends the previous functionality: if getCastOpcode previously accepted two vector types (i.e. didn't assert) then it still will and returns the same opcode (BitCast). That's because before it would only accept vectors with the same bitwidth, and the new code only touches vectors with the same length. However if two vectors have both the same bitwidth and the same length then their element types have the same bitwidth, so the new logic will return BitCast as before. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@131530 91177308-0d34-0410-b5e6-96231b3b80d8

* First step in fixing PR8927:Rafael Espindola2011-01-081-0/+20
| | | | | | | | | | | | | | | | | | | Add a unnamed_addr bit to global variables and functions. This will be used to indicate that the address is not significant and therefore the constant or function can be merged with others. If an optimization pass can show that an address is not used, it can set this. Examples of things that can have this set by the FE are globals created to hold string literals and C++ constructors. Adding unnamed_addr to a non-const global should have no effect unless an optimization can transform that global into a constant. Aliases are not allowed to have unnamed_addr since I couldn't figure out any use for it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@123063 91177308-0d34-0410-b5e6-96231b3b80d8

* Get rid of static constructors for pass registration. Instead, every pass ↵Owen Anderson2010-10-191-8/+29
| | | | | | | | | | | | | | | | | | 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
