2010-03-14fix AsmPrinter::GetBlockAddressSymbol to always return a uniqueChris Lattner
label instead of trying to form one based on the BB name (which causes collisions if the name is empty). This fixes PR6608 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98495 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-10Lower add (mul a, b), c into MACCU / MACCS nodes which translateRichard Osborne
directly to the maccu / maccs instructions. We handle this in ExpandADDSUB since after type legalisation it is messy to recognise these operations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98150 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-15use XCore-specific section with xcore specific cp/dp flags to restore Chris Lattner
support for globals going into the appropriate sections with the flags. This hopefully finishes unbreaking the previous behavior that I broke before. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79079 91177308-0d34-0410-b5e6-96231b3b80d8

offset from a 32 bit aligned base as follows: ldw low, base[offset >> 2] ldw high, base[(offset >> 2) + 1] shr low_shifted, low, (offset & 0x3) * 8 shl high_shifted, high, 32 - (offset & 0x3) * 8 or result, low_shifted, high_shifted Expand 32 bit loads / stores with 16 bit alignment into two 16 bit loads / stores. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75902 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-16Custom lower unaligned 32 bit stores and loads into libcalls. This is Richard Osborne
a big code size win since before they were expanding to upto 16 instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75901 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-04Split the Add, Sub, and Mul instruction opcodes into separateDan Gohman
integer and floating-point opcodes, introducing FAdd, FSub, and FMul. For now, the AsmParser, BitcodeReader, and IRBuilder all preserve backwards compatability, and the Core LLVM APIs preserve backwards compatibility for IR producers. Most front-ends won't need to change immediately. This implements the first step of the plan outlined here: http://nondot.org/sabre/LLVMNotes/IntegerOverflow.txt git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72897 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-20Fix for PR4235: to build a floating-point value from integer parts, Eli Friedman
build an integer and cast that to a float. This fixes a crash caused by trying to split an f32 into two f16's. This changes the behavior in test/CodeGen/XCore/fneg.ll because that testcase now triggers a DAGCombine which converts the fneg into an integer operation. If someone is interested, it's probably possible to tweak the test to generate an actual fneg. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72162 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-14Add pseudo instructions to the XCore for (load|store|load address) of aRichard Osborne
frame index. eliminateFrameIndex will replace these instructions with (LDWSP|STWSP|LDAWSP) or (LDW|STW|LDAWF) if a frame pointer is in use. This fixes PR 3324. Previously we used LDWSP, STWSP, LDAWSP before frame pointer elimination. However since they were marked as implicitly using SP they could not be rematerialised. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62238 91177308-0d34-0410-b5e6-96231b3b80d8
