* Properly emit ctors / dtors with priorities into desired sectionsAnton Korobeynikov2012-01-251-22/+17
| | | | | | | | and let linker handle the rest. This finally fixes PR5329 llvm-svn: 148990
* Use the right method to get the # elements in a CDS.Chris Lattner2012-01-251-3/+3
| | | | llvm-svn: 148897
* An option to selectively enable part of ARM EHABI support.Evgeniy Stepanov2012-01-241-5/+14
| | | | | | | | This change adds an new option --arm-enable-ehabi-descriptors that enables emitting unwinding descriptors. This provides a mode with a working backtrace() without the (currently broken) exception support. llvm-svn: 148800
* Bit pack DIE structures better.Benjamin Kramer2012-01-241-23/+23
| | | | | | 16 bits are sufficient to store attributes, tags and forms. llvm-svn: 148799
* Remove generation of DW_AT_sibling. Nothing as far as I can tell uses it.Eric Christopher2012-01-243-26/+0
| | | | | | | | Saves about 1.5% on debug info size. rdar://10278198 llvm-svn: 148794
* Add AsmPrinter (aka MCLowering) support for ConstantDataSequential, Chris Lattner2012-01-241-32/+91
| | | | | | | | and clean up some other misc stuff. Unlike ConstantArray, we will prefer to emit .fill directives for "String" arrays that all have the same value, since they are denser than emitting a .ascii llvm-svn: 148793
* Revert r148686 (and r148694, a fix to it) due to a serious layeringChandler Carruth2012-01-241-20/+5
| | | | | | | | | | | | | | | | | | violation -- MC cannot depend on CodeGen. Specifically, the MCTargetDesc component of each target is actually a subcomponent of the MC library. As such, it cannot depend on the target-independent code generator, because MC itself cannot depend on the target-independent code generator. This change moved a flag from the ARM MCTargetDesc file ARMMCAsmInfo.cpp to the CodeGen layer in ARMException.cpp, leaving behind an 'extern' to refer back to it. That layering order isn't viable givin the constraints outlined above. Commandline flags are designed to be static specifically to avoid these types of bugs. Fixing this is likely going to require some non-trivial refactoring. llvm-svn: 148759

* An option to selectively enable parts of ARM EHABI support.Evgeniy Stepanov2012-01-231-5/+20
| | | | | | | | This change adds an new value to the --arm-enable-ehabi option that disables emitting unwinding descriptors. This mode gives a working backtrace() without the (currently broken) exception support. llvm-svn: 148686

* Removing unused default switch cases in switches over enums that already ↵David Blaikie2012-01-161-1/+1

* Fix the code that was WRONG.Bill Wendling2012-01-121-0/+65

| | | | | | | | | | | | | | generator to it. For non-bundle instructions, these behave exactly the same as the MC layer API. For properties like mayLoad / mayStore, look into the bundle and if any of the bundled instructions has the property it would return true. For properties like isPredicable, only return true if *all* of the bundled instructions have the property. For properties like canFoldAsLoad, isCompare, conservatively return false for bundles. llvm-svn: 146026

* Use logarithmic units for basic block alignment.Jakob Stoklund Olesen2011-12-061-1/+1
| | | | | | | | | | | | | | | | | This was actually a bit of a mess. TLI.setPrefLoopAlignment was clearly documented as taking log2(bytes) units, but the x86 target would still set a preferred loop alignment of '16'. CodePlacementOpt passed this number on to the basic block, and AsmPrinter interpreted it as bytes. Now both MachineFunction and MachineBasicBlock use logarithmic alignments. Obviously, MachineConstantPool still measures alignments in bytes, so we can emulate the thrill of using as. llvm-svn: 145889

| | | | | | | | | | | | change, now you need a TargetOptions object to create a TargetMachine. Clang patch to follow. One small functionality change in PTX. PTX had commented out the machine verifier parts in their copy of printAndVerify. That now calls the version in LLVMTargetMachine. Users of PTX who need verification disabled should rely on not passing the command-line flag to enable it. llvm-svn: 145714

* We currently use a callback to handle an IL pass deleting a BB that stillRafael Espindola2011-11-151-0/+12
| | | | | | | | | | | has a reference to it. Unfortunately, that doesn't work for codegen passes since we don't get notified of MBB's being deleted (the original BB stays). Use that fact to our advantage and after printing a function, check if any of the IL BBs corresponds to a symbol that was not printed. This fixes pr11202. llvm-svn: 144674
* The dwarf standard says that the only differences between a out-of-lineRafael Espindola2011-11-121-0/+7
| | | | | | | | | | | | | | instance and a concrete inlined instance are the use of DW_TAG_subprogram instead of DW_TAG_inlined_subroutine and the who owns the tree. We were also omitting DW_AT_inline from the abstract roots. To fix this, make sure we mark abstract instance roots with DW_AT_inline even when we have only out-of-line instances referring to them with DW_AT_abstract_origin. FileCheck is not a very good tool for tests like this, maybe we should add a -verify mode to llvm-dwarfdump. llvm-svn: 144441
