* Add support for a new extension to the .file directive:Nick Lewycky2011-10-17
| | | | | | | | | | | .file filenumber "directory" "filename" This removes one join+split of the directory+filename in MC internals. Because bitcode files have independent fields for directory and filenames in debug info, this patch may change the .o files written by existing .bc files. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142300 91177308-0d34-0410-b5e6-96231b3b80d8
* Enhance llvm::SourceMgr to support diagnostic ranges, the same way clang ↵Chris Lattner2011-10-16
| | | | | | | | | | | | | | | | | does. Enhance the X86 asmparser to produce ranges in the one case that was annoying me, for example: test.s:10:15: error: invalid operand for instruction movl 0(%rax), 0(%edx) ^~~~~~~ It should be straight-forward to enhance filecheck, tblgen, and/or the .ll parser to use ranges where appropriate if someone is interested. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142106 91177308-0d34-0410-b5e6-96231b3b80d8

* Move the registered target printing in version strings completely out ofChandler Carruth2011-07-22
| | | | | | | | | | | | | | | | | the Support library. Now its part of the TargetRegistry, and the three commands that care about this explicitly register this extra bit of version information. The set of commands which care was computed by intersecting those which use the Support library's version string printing and those that initialize all the registered targets in a way that produces a meaningful list. The only odd ball out is that 'clang -cc1as -version' no longer prints the registered targets. I don't think anyone is really interested in that (especially as the fact that llvm-mc does so is under a FIXME), but if someone really does want this back I'll happily apply the same patch there. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135757 91177308-0d34-0410-b5e6-96231b3b80d8
* - Move CodeModel from a TargetMachine global option to MCCodeGenInfo.Evan Cheng2011-07-20
| | | | | | | | | - Introduce JITDefault code model. This tells targets to set different default code model for JIT.

* - Eliminate MCCodeEmitter's dependency on TargetMachine. It now uses MCInstrInfoEvan Cheng2011-07-11
| | | | | | | | | | | | | and MCSubtargetInfo. - Added methods to update subtarget features (used when targets automatically detect subtarget features or switch modes). - Teach X86Subtarget to update MCSubtargetInfo features bits since the MCSubtargetInfo layer can be shared with other modules. - These fixes .code 16 / .code 32 support since mode switch is updated in MCSubtargetInfo so MC code emitter can do the right thing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134884 91177308-0d34-0410-b5e6-96231b3b80d8
* Change createAsmParser to take a MCSubtargetInfo instead of triple,Evan Cheng2011-07-09
| | | | | | | | | | CPU, and feature string. Parsing some asm directives can change subtarget state (e.g. .code 16) and it must be reflected in other modules (e.g. MCCodeEmitter). That is, the MCSubtargetInfo instance must be shared. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134795 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix the ridiculous SubtargetFeatures API where it implicitly expects CPU name toEvan Cheng2011-06-30
| | | | | | | | | | | be the first encoded as the first feature. It then uses the CPU name to look up features / scheduling itineray even though clients know full well the CPU name being used to query these properties. The fix is to just have the clients explictly pass the CPU name! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134127 91177308-0d34-0410-b5e6-96231b3b80d8

* Added *hidden* flags -print-options and -print-all-options soAndrew Trick2011-04-05
| | | | | | | | | | | | | | | | | | | | developers can see if their driver changed any cl::Option's. The current implementation isn't perfect but handles most kinds of options. This is nice to have when decomposing the stages of compilation and moving between different drivers. It's also a good sanity check when comparing results produced by different command line invocations that are expected to produce the comparable results. Note: This is not an attempt to prolong the life of cl::Option. On the contrary, it's a placeholder for a feature that must exist when cl::Option is replaced by a more appropriate framework. A new framework needs: a central option registry, dynamic name lookup, non-global containers of option values (e.g. per-module, per-function), *and* the ability to print options values and their defaults at any point during compilation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128910 91177308-0d34-0410-b5e6-96231b3b80d8

* Kill ModuleProvider and ghost linkage by inverting the relationship betweenJeffrey Yasskin2010-01-27
| | | | | | | | | | | | | | | | | | | | | | Modules and ModuleProviders. Because the "ModuleProvider" simply materializes GlobalValues now, and doesn't provide modules, it's renamed to "GVMaterializer". Code that used to need a ModuleProvider to materialize Functions can now materialize the Functions directly. Functions no longer use a magic linkage to record that they're materializable; they simply ask the GVMaterializer. Because the C ABI must never change, we can't remove LLVMModuleProviderRef or the functions that refer to it. Instead, because Module now exposes the same functionality ModuleProvider used to, we store a Module* in any LLVMModuleProviderRef and translate in the wrapper methods. The bindings to other languages still use the ModuleProvider concept. It would probably be worth some time to update them to follow the C++ more closely, but I don't intend to do it.
