2013-03-22Revert r177543: Add timing of the IR parsing code with a newChandler Carruth
-time-ir-parsing flag This breaks the layering of the Support library. We can't add an implementation side to IRReader because it refers directly to entities only accessible as part of the IR, AsmParser, and BitcodeReader libraries. It can only be used in a context where all of those libraries will be available. We'll need to find some other way to get this functionality, and hopefully solve the long-standing layering problem of IRReader.h... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177695 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-21Refactor the filename/directory information in DISubprogram to refer ↵David Blaikie

2013-03-21Hoist the definition of getTypeSizeInBits to be inlinable and in theChandler Carruth
header. This method is called in the hot path for *many* passes, SROA is what caught my interest. A common pattern is that which branch of the switch should be taken is known in the callsite and so it is a very good candidate for inlining and simplification. Moving it into the header allows the optimizer to fold a lot of boring, repeatitive code in callers of this routine. I'm seeing pretty significant speedups in parts of SROA and I suspect other passes will see similar speedups if they end up working with type sizes frequently. I've not seen any significant growth of the binaries as a consequence, but let me know if you see anything suspicious here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177632 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-20Debug info: refactor the first field of DICompileUnit to be a raw ↵David Blaikie
file/directory pair This removes the DICompileUnit special case from DIScope. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177610 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-20Use pre-inc, pre-dec when possible.Jakub Staszak
They are generally faster (at least not slower) than post-inc, post-dec. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177608 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-20Make sure TableGen exits with an error code after printing errors.Jakob Stoklund Olesen
This makes it possible to report multiple errors in one invocation. There are already calls to PrintError in CodeGenDAGPatterns.cpp which previously would not cause TableGen to fail. <rdar://problem/13463339> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177573 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-20Refactor file/directory path in namespace debug info to refer directly to ↵David Blaikie

2013-03-20Reorder the DIFile parameter in DINameSpaceDavid Blaikie
Moving the DIFile parameter to immediately proceed the tag so that it will be a common prefix with other DIScopes (once the DIFile is replaced with the raw file/directory pair). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177492 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-20Provide more details for DINameSpace debug info in the IR comment annotationsDavid Blaikie
Sorry for the version skew - I should've committed this before the corresponding Clang test case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177486 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-20Refactor the DIFile (2nd) parameter to DITypes to be an MDNode reference to ↵David Blaikie
a raw directory/file pair This makes DIType's first non-tag parameter the same as DIFile's, allowing them to both share the common implementation of getFilename/getDirectory in DIScope. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177467 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-19Move the DIFile operand to DITypes from the 4th operand to the 2nd.David Blaikie
This is another step along the way to making all DIScopes have a common prefix which can be added to in a general manner to support using directives (DW_TAG_imported_module). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177462 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-19The Linker interface has some dead code after the cleanup in r172749Eli Bendersky
(and possibly others). The attached patch removes it, and tries to update comments accordingly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177406 91177308-0d34-0410-b5e6-96231b3b80d8

And enables SmallVector's pod optimizations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177281 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-17Split out filename & directory from DIFile to start generalizing over DIScopesDavid Blaikie
This is the first step to making all DIScopes have a common metadata prefix (so that things (using directives, for example) that can appear in any scope can be added to that common prefix). DIFile is itself a DIScope so the common prefix of all DIScopes cannot be a DIFile - instead it's the raw filename/directory name pair. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177239 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-15Add SchedRW as an Instruction field.Jakob Stoklund Olesen
Don't require instructions to inherit Sched<...>. Sometimes it is more convenient to say: let SchedRW = ... in { ... } Which is now possible. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177199 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-15[ADT] Fix StringSet::insert() to not allocate on every lookup.Daniel Dunbar
- The previous implementation always constructed the StringMap entry, even if the key was present in the set. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177178 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-14Add a new method which enables one to change register classes.Reed Kotler
See the Mips16ISetLowering.cpp patch to see a use of this. For now now the extra code in Mips16ISetLowering.cpp is a nop but is used for test purposes. Mips32 registers are setup and then removed and then the Mips16 registers are setup. Normally you need to add register classes and then call computeRegisterProperties. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177120 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-14MachineModel: Add a ProcResGroup class.Andrew Trick
This allows abitrary groups of processor resources. Using something in a subset automatically counts againts the superset. Currently, this only works if the superset is also a ProcResGroup as opposed to a SuperUnit. This allows SandyBridge to be expressed naturally, which will be checked in shortly. def SBPort01 : ProcResGroup<[SBPort0, SBPort1]>; def SBPort15 : ProcResGroup<[SBPort1, SBPort5]>; def SBPort23 : ProcResGroup<[SBPort2, SBPort3]>; def SBPort015 : ProcResGroup<[SBPort0, SBPort1, SBPort5]>; git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177112 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-14Move estimateStackSize from ARM into MachineFrameInfoHal Finkel
This is a generic function (derived from PEI); moving it into MachineFrameInfo eliminates a current redundancy between the ARM and AArch64 backends, and will allow it to be used by the PowerPC target code. No functionality change intended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177111 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-14Provide the register scavenger to processFunctionBeforeFrameFinalizedHal Finkel
Add the current PEI register scavenger as a parameter to the processFunctionBeforeFrameFinalized callback. This change is necessary in order to allow the PowerPC target code to set the register scavenger frame index after the save-area offset adjustments performed by processFunctionBeforeFrameFinalized. Only after these adjustments have been made is it possible to estimate the size of the stack frame. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177108 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-14Refactor GCOV's six constructor arguments into a struct with a getter thatNick Lewycky
constructs default arguments. It can now take default arguments from cl::opt'ions. Add a new -default-gcov-version=... option, and actually test it! Sink the reverse-order of the version into GCOVProfiling, hiding it from our users. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177002 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-13Reset some of the target options which affect code generation.Bill Wendling
This doesn't reset all of the target options within the TargetOptions object. This is because some of those are ABI-specific and must be determined if it's okay to change those on the fly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176986 91177308-0d34-0410-b5e6-96231b3b80d8
