* Use lightweight DebugInfo objects directly.Devang Patel2009-01-151-82/+65
| | | | llvm-svn: 62276
* Move a few containers out of ScheduleDAGInstrs::BuildSchedGraphDan Gohman2009-01-1512-108/+103
| | | | | | | | | | | and into the ScheduleDAGInstrs class, so that they don't get destructed and re-constructed for each block. This fixes a compile-time hot spot in the post-pass scheduler. To help facilitate this, tidy and do some minor reorganization in the scheduler constructor functions. llvm-svn: 62275

* Do not construct debug scope if RootScope *is* null.Devang Patel2009-01-141-1/+1

* Removoe MachineModuleInfo methods (and related DebugInfoDesc class ↵Devang Patel2009-01-133-2453/+10

* Keep "has debug info" big in MachineModuleInfo to avoid circular dependency ↵Devang Patel2009-01-132-0/+2

* Undo previous checkin.Devang Patel2009-01-132-9/+2

* Use DwarfWriter to record dbg variables.Devang Patel2009-01-132-4/+11

* Use dwarf writer to decide whether the module has debug info or not.Devang Patel2009-01-132-2/+9
| | | | llvm-svn: 62184
* Use assertions to check for conditions that should never happen.Dan Gohman2009-01-131-12/+6

* The list-td and list-tdrr schedulers don't yet support physregDan Gohman2009-01-132-2/+10
| | | | | | | | | | | scheduling dependencies. Add assertion checks to help catch this. It appears the Mips target defaults to list-td, and it has a regression test that uses a physreg dependence. Such code was liable to be miscompiled, and now evokes an assertion failure. llvm-svn: 62177
* Avoid referring to edge D after the Succs or Preds arrays haveDan Gohman2009-01-131-3/+3
| | | | | | | been modified, to avoid trouble in the (unlikely) scenario that D is a reference to an element in one of those arrays. llvm-svn: 62173

| | | | | | | | via two paths, process it once not twice, d'oh! Analysis, testcase and original patch thanks to Mon Ping Wang. llvm-svn: 62169
* Fix some typos. Also, the WidenedVectors mapDuncan Sands2009-01-132-9/+20
| | | | | | was not being cleaned by ExpungeNode. llvm-svn: 62167
* Correct a comment - this is not a sign extension.Duncan Sands2009-01-131-1/+1

| | | | | | physical register, it's not necessarily defined by a copy. We have to watch out it doesn't clobber any sub-register that might be live during its live interval. If the live interval crosses a basic block, then it's not safe to check with the less conservative check (by scanning uses and defs) because it's possible a sub-register might be live out of the block. llvm-svn: 62144
* Use DebugInfo interface to lower dbg_* intrinsics.Devang Patel2009-01-136-56/+69

* If multiple compile units are seen then emit them independently. In other ↵Devang Patel2009-01-121-65/+74

* Avoid cast<>, use light weith wrapper directly.Devang Patel2009-01-121-3/+3

* Add DwarfWriter interface to mainipulate source location info.Devang Patel2009-01-121-45/+91
| | | | | | ( May be this info should be directly handled by the dwarf writer ? ) llvm-svn: 62096
* Clear debug info at the end of function processing.Devang Patel2009-01-121-1/+12

That means we are only treating "expensive to copy" register dependency as physical register dependency. Also future proof the scheduler to handle "normal" physical register dependencies. The code is not exercised yet. llvm-svn: 62074
* More two-address fixes. This gets lua working with join-creation enabled.Owen Anderson2009-01-121-6/+10

| | | | llvm-svn: 61991
* Convert DwarfWriter into a pass.Devang Patel2009-01-081-12/+13
| | | | | | Now Users request DwarfWriter through getAnalysisUsage() instead of creating an instance of DwarfWriter object directly. llvm-svn: 61955

* Add APIs to record regions and variables.Devang Patel2009-01-081-0/+27
| | | | | | Again, shamelessly copied from MMI. llvm-svn: 61912
* Add APIs to manage scope using DebugInfo interface.Devang Patel2009-01-081-0/+297
| | | | | | This is a shameless copy of similar APIs from MachineModuleInfo. The copy from MMI will be deleted in near future. llvm-svn: 61908
* Remove redundant 'else's. No functionality change.Dan Gohman2009-01-071-7/+6

* The coalescer does not coalesce a virtual register to a physical register if ↵Evan Cheng2009-01-072-20/+84
| | | | | | | | | | | | | | any of the physical register's sub-register live intervals overlaps with the virtual register. This is overly conservative. It prevents a extract_subreg from being coalesced away: v1024 = EDI // not killed = = EDI One possible solution is for the coalescer to examine the sub-register live intervals in the same manner as the physical register. Another possibility is to examine defs and uses (when needed) of sub-registers. Both solutions are too expensive. For now, look for "short virtual intervals" and scan instructions to look for conflict instead. This is a small win on x86-64. e.g. It shaves 403.gcc by ~80 instructions. llvm-svn: 61847
* Fix a bug in ComputeLinearIndex computation handling multi-levelDan Gohman2009-01-061-1/+3
| | | | | | | | aggregate types. Don't increment the current index after reaching the end of a struct, as it will already be pointing at one-past-the end. This fixes PR3288. llvm-svn: 61828
