* Allow the source module to be materialized during the linking process.Tanya Lattner2011-10-14

* Make it possible to use the linker without destroying the source module. ↵Tanya Lattner2011-10-11
| | | | | | | | | | | | | | | This is so the source module can be linked to multiple other destination modules. For all that used LinkModules() before, they will continue to destroy the source module as before.

* Rewrite the CMake build to use explicit dependencies between libraries,Chandler Carruth2011-07-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | specified in the same file that the library itself is created. This is more idiomatic for CMake builds, and also allows us to correctly specify dependencies that are missed due to bugs in the GenLibDeps perl script, or change from compiler to compiler. On Linux, this returns CMake to a place where it can relably rebuild several targets of LLVM. I have tried not to change the dependencies from the ones in the current auto-generated file. The only places I've really diverged are in places where I was seeing link failures, and added a dependency. The goal of this patch is not to start changing the dependencies, merely to move them into the correct location, and an explicit form that we can control and change when necessary. This also removes a serialization point in the build because we don't have to scan all the libraries before we begin building various tools. We no longer have a step of the build that regenerates a file inside the source tree. A few other associated cleanups fall out of this. This isn't really finished yet though. After talking to dgregor he urged switching to a single CMake macro to construct libraries with both sources and dependencies in the arguments. Migrating from the two macros to that style will be a follow-up patch. Also, llvm-config is still generated with GenLibDeps.pl, which means it still has slightly buggy dependencies. The internal CMake 'llvm-config-like' macro uses the correct explicitly specified dependencies however. A future patch will switch llvm-config generation (when using CMake) to be based on these deps as well. This may well break Windows. I'm getting a machine set up now to dig into any failures there. If anyone can chime in with problems they see or ideas of how to solve them for Windows, much appreciated. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136433 91177308-0d34-0410-b5e6-96231b3b80d8

* Land the long talked about "type system rewrite" patch. ThisChris Lattner2011-07-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | patch brings numerous advantages to LLVM. One way to look at it is through diffstat: 109 files changed, 3005 insertions(+), 5906 deletions(-) Removing almost 3K lines of code is a good thing. Other advantages include: 1. Value::getType() is a simple load that can be CSE'd, not a mutating union-find operation. 2. Types a uniqued and never move once created, defining away PATypeHolder. 3. Structs can be "named" now, and their name is part of the identity that uniques them. This means that the compiler doesn't merge them structurally which makes the IR much less confusing. 4. Now that there is no way to get a cycle in a type graph without a named struct type, "upreferences" go away. 5. Type refinement is completely gone, which should make LTO much MUCH faster in some common cases with C++ code. 6. Types are now generally immutable, so we can use "Type *" instead "const Type *" everywhere. Downsides of this patch are that it removes some functions from the C API, so people using those will have to upgrade to (not yet added) new API. "LLVM 3.0" is the right time to do this. There are still some cleanups pending after this, this patch is large enough as-is. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134829 91177308-0d34-0410-b5e6-96231b3b80d8

* Revamp the ValueMapper interfaces in a couple ways:Chris Lattner2011-01-08
| | | | | | | | | | | | | | | | | | 1. Take a flags argument instead of a bool. This makes it more clear to the reader what it is used for. 2. Add a flag that says that "remapping a value not in the map is ok". 3. Reimplement MapValue to share a bunch of code and be a lot more efficient. For lookup failures, don't drop null values into the map. 4. Using the new flag a bunch of code can vaporize in LinkModules and LoopUnswitch, kill it. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@123058 91177308-0d34-0410-b5e6-96231b3b80d8

* Reapply r112091 and r111922, support for metadata linking, with aDan Gohman2010-08-26
| | | | | | | | | | | | | | | fix: add a flag to MapValue and friends which indicates whether any module-level mappings are being made. In the common case of inlining, no module-level mappings are needed, so MapValue doesn't need to examine non-function-local metadata, which can be very expensive in the case of a large module with really deep metadata (e.g. a large C++ program compiled with -g). This flag is a little awkward; perhaps eventually it can be moved into the ClonedCodeInfo class. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112190 91177308-0d34-0410-b5e6-96231b3b80d8
