* Only erase virtregs with no uses left.Jakob Stoklund Olesen2012-05-222-4/+133
| | | | | | | | | Also make sure registers aren't erased twice if the dead def mentions the register twice. This fixes PR12911. llvm-svn: 157254

| | | | | | | | | | | | leader table. That's because it wasn't expecting instructions to turn up as leader for a value number that is not its own, but equality propagation could create this situation. One solution is to have the leader table use a WeakVH but this slows down GVN by about 5%. Instead just have equality propagation not add instructions to the leader table, only constants and arguments. In theory this might cause GVN to run more (each time it changes something it runs again) but it doesn't seem to occur enough to cause a slow down. llvm-svn: 157251

* ScheduleOptimizer: Simplify some codeTobias Grosser2012-05-221-22/+10
| | | | | | We now use isl_map_equate, which makes the code a lot simpler. llvm-svn: 157246
* ScopInfo: Add parameter bounds to contextTobias Grosser2012-05-224-2/+39
| | | | | | | | Derive the maximal and minimal values of a parameter from the type it has. Add this information to the scop context. This information is needed, to derive optimal types during code generation. llvm-svn: 157245

| | | | llvm-svn: 157244
* ScopInfo: SCEVUnknowns are always parametersTobias Grosser2012-05-221-15/+1
| | | | | | | | There is no need for special code to handle SCEVUnknowns. SCEVUnkowns are always parameters and will be handled by the generic parameter handling code in visit(). llvm-svn: 157243
* Move isParallelFor into CodeGenerationTobias Grosser2012-05-223-22/+24

* This patch adds a predicate to existing mips32 and mips64 so that thoseAkira Hatanaka2012-05-226-101/+134
| | | | | | | | | | | | | | | | | | | instruction encodings can be excluded during mips16 processing. This revision fixes the issue raised by Jim Grosbach. bool hasStandardEncoding() const { return !inMips16Mode(); } When micromips is added it will be bool StandardEncoding() const { return !inMips16Mode()&& !inMicroMipsMode(); } No additional testing is needed other than to assure that there is no regression from this patch.

* rdar://problem/11487457Johnny Chen2012-05-223-0/+80
| | | | | | | | Add convenience registers eax, ebx, ecx, edx, edi, esi, ebp, esp to the 'register read' command for x86_64. Add a GDBRemoteRegisterContext::Addx86_64ConvenienceRegisters() method called from ProcessGDBRemote::BuildDynamicRegisterInfo(). Servicing of eax, for example, is accomplished by delegating to rax with an adjusted offset into the register context. llvm-svn: 157230

| | | | | | | | | | | argument to the relevant "break set" commands to set this per breakpoint. Also, some CreateBreakpoint API's in the lldb_private namespace had "internal" first and "skip_prologue" second. "internal should always be last. Fixed that. rdar://problem/11484729 llvm-svn: 157225

* ARM: .end_data_region mismatch in Thumb2.Jim Grosbach2012-05-211-2/+5
| | | | | | | | | | 32-bit offset jump tables just use real branch instructions and so aren't marked as data regions. We were still emitting the .end_data_region marker though, which assert()ed. rdar://11499158 llvm-svn: 157221
* Added support for rvalue references in debug informationSean Callanan2012-05-214-6/+92
| | | | | | | | (actually, mainly just hooked up support that was already there). Added a test case, although it's expected to fail right now unless you're using top-of-tree LLVM. llvm-svn: 157220
