| | | | | | | | | This class is used to represent SubRegIndex instances instead of the raw Record pointers that were used before. No functional change intended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149418 91177308-0d34-0410-b5e6-96231b3b80d8
* Remove Deprecated FeaturesDavid Greene2012-01-271-250/+51
| | | | | | | | | | | | Move to a model where we build whatever branches are checked out in the source directories. This was a bit too smart (and complicated) in handling details best left to the user and the revision control system. In addition, get rid of support for llvm-gcc and building gcc as these are no longer necessary. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149149 91177308-0d34-0410-b5e6-96231b3b80d8

* Help GCC along with code that's actually unreachable.David Blaikie2012-01-221-0/+3
| | | | | | | | Unfortunately I don't think there's a fix for this that will work upstream and also satisfy Clang's -Wunreachable-code, which is a pity. But I'll give it some more thought -perhaps there's some way out. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148645 91177308-0d34-0410-b5e6-96231b3b80d8

* Extend Attributes to 64 bitsKostya Serebryany2012-01-201-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Problem: LLVM needs more function attributes than currently available (32 bits). One such proposed attribute is "address_safety", which shows that a function is being checked for address safety (by AddressSanitizer, SAFECode, etc). Solution: - extend the Attributes from 32 bits to 64-bits - wrap the object into a class so that unsigned is never erroneously used instead - change "unsigned" to "Attributes" throughout the code, including one place in clang. - the class has no "operator uint64 ()", but it has "uint64_t Raw() " to support packing/unpacking. - the class has "safe operator bool()" to support the common idiom: if (Attributes attr = getAttrs()) useAttrs(attr); - The CTOR from uint64_t is marked explicit, so I had to add a few explicit CTOR calls - Add the new attribute "address_safety". Doing it in the same commit to check that attributes beyond first 32 bits actually work. - Some of the functions from the Attribute namespace are worth moving inside the class, but I'd prefer to have it as a separate commit. Tested: "make check" on Linux (32-bit and 64-bit) and Mac (10.6) built/run spec CPU 2006 on Linux with clang -O2. This change will break clang build in lib/CodeGen/CGCall.cpp. The following patch will fix it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148553 91177308-0d34-0410-b5e6-96231b3b80d8
* Add a CoveredBySubRegs property to Register descriptions.Jakob Stoklund Olesen2012-01-182-12/+41
| | | | | | | | | | | | | | | | When set, this bit indicates that a register is completely defined by the value of its sub-registers. Use the CoveredBySubRegs property to infer which super-registers are call-preserved given a list of callee-saved registers. For example, the ARM registers D8-D15 are callee-saved. This now automatically implies that Q4-Q7 are call-preserved. Conversely, Win64 callees save XMM6-XMM15, but the corresponding YMM6-YMM15 registers are not call-preserved because they are not fully defined by their sub-registers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148363 91177308-0d34-0410-b5e6-96231b3b80d8

* Add TableGen support for callee saved registers.Jakob Stoklund Olesen2012-01-173-0/+56
| | | | | | | | | Targets can now add CalleeSavedRegs defs to their *CallingConv.td file. TableGen will use this to create a *_SaveList array suitable for returning from getCalleeSavedRegs() as well as a *_RegMask bit mask suitable for returning from getCallPreservedMask(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148346 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | helpful to someone else. This lets lldb give sane output for SmallVectors, e.g. Before: (lldb) p sv (llvm::SmallVector<int, 10>) $0 = { (llvm::SmallVectorImpl<int>) llvm::SmallVectorImpl<int> = { (llvm::SmallVectorTemplateBase<int>) llvm::SmallVectorTemplateBase<int> = { (llvm::SmallVectorTemplateCommon<int>) llvm::SmallVectorTemplateCommon<int> = { (llvm::SmallVectorBase) llvm::SmallVectorBase = { (void *) BeginX = 0x00007fff5fbff960 ... } After: (lldb) p sv (llvm::SmallVector<int, 10>) $0 = { (int) [0] = 42 (int) [1] = 23 ... } The script is still a bit rough so expect crashes for vectors of complex types. Synthetic children are _not_ available in xcode 4.2, newer LLDBs should work though. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148308 91177308-0d34-0410-b5e6-96231b3b80d8
