2012-12-21Don't skip __DWARF,Rafael Espindola
Now that we don't merge section and segment names, we don't need to skip the segment name to get to the section name. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170839 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-21Add a function to get the segment name of a section.Rafael Espindola
On MachO, sections also have segment names. When a tool looking at a .o file prints a segment name, this is what they mean. In reality, a .o has only one anonymous, segment. This patch adds a MachO only function to fetch that segment name. I named it getSectionFinalSegmentName since the main use for the name seems to be inform the linker with segment this section should go to. The patch also changes MachOObjectFile::getSectionName to return just the section name instead of computing SegmentName,SectionName. The main difference from the previous patch is that it doesn't use InMemoryStruct. It is extremely dangerous: if the endians match it returns a pointer to the file buffer, if not, it returns a pointer to an internal buffer that is overwritten in the next API call. We should change all of this code to use support::detail::packed_endian_specific_integral like ELF, but since these functions only handle strings, they work with big and little endian machines as is. I have tested this by installing ubuntu 12.10 ppc on qemu, that is why it took so long :-) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170838 91177308-0d34-0410-b5e6-96231b3b80d8

memory bound checks. Before the fix we were able to vectorize this loop from the Livermore Loops benchmark: for ( k=1 ; k<n ; k++ ) x[k] = x[k-1] + y[k]; git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170811 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-20Require the two-argument MI::addOperand(MF, MO) for dangling instructions.Jakob Stoklund Olesen
Instructions that are inserted in a basic block can still be decorated with addOperand(MO). Make the two-argument addOperand() function contain the actual implementation. This function will now always have a valid MF reference that it can use for memory allocation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170798 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-20Add an MF argument to MI::copyImplicitOps().Jakob Stoklund Olesen
This function is often used to decorate dangling instructions, so a context reference is required to allocate memory for the operands. Also add a corresponding MachineInstrBuilder method. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170797 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-20LoopVectorize: Fix a bug in the scalarization of instructions.Nadav Rotem
Before if-conversion we could check if a value is loop invariant if it was declared inside the basic block. Now that loops have multiple blocks this check is incorrect.

2012-12-20Use MachineInstrBuilder in InstrEmitter.Jakob Stoklund Olesen
This is supposed to be a mechanical change with no functional effects. InstrEmitter can generate all types of MachineOperands which revealed that MachineInstrBuilder was missing a few methods, added by this patch. Besides providing a context pointer to MI::addOperand(), MachineInstrBuilder seems like a better fit for this code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170712 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-20Add a new attribute, 'noduplicate'. If a function contains a noduplicate ↵James Molloy
call, the call cannot be duplicated - Jump threading, loop unrolling, loop unswitching, and loop rotation are inhibited if they would duplicate the call. Similarly inlining of the function is inhibited, if that would duplicate the call (in particular inlining is still allowed when there is only one callsite and the function has internal linkage). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170704 91177308-0d34-0410-b5e6-96231b3b80d8
