2010-11-22Refactor the ELFRelocationEntry (pull up) and move the arch-specific statics ↵Jason W Kim
to inside the class where it belongs. Next step is to rationally break apart the RecordRelocation() Probably the step will be to have 1 member function for ech slot of the ELFRelocationEntry() git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119978 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-22Fix epilogue codegen to avoid leaving the stack pointer in an invalidEvan Cheng
state. Previously Thumb2 would restore sp from fp like this: mov sp, r7 sub, sp, #4 If an interrupt is taken after the 'mov' but before the 'sub', callee-saved registers might be clobbered by the interrupt handler. Instead, try restoring directly from sp: add sp, #4 Or, if necessary (with VLA, etc.) use a scratch register to compute sp and then restore it: sub.w r4, r7, #8 mov sp, r7 rdar://8465407 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119977 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-22Implement the "if (X == 6 || X == 4)" -> "if ((X|2) == 6)" optimization.Benjamin Kramer
This currently only catches the most basic case, a two-case switch, but can be extended later. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119964 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-21Initialize MemDep's TD member so buildbots don't trip over an uninitialized ↵Benjamin Kramer
pointer (TD is passed to PHITransAddr). I wonder why this didn't explode earlier. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119944 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-21Add a rather pointless InstructionSimplify transform, inspired by recent ↵Duncan Sands
constant folding improvements: if P points to a type of size zero, turn "gep P, N" into "P". More generally, if a gep index type has size zero, instcombine could replace the index with zero, but that is not done here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119942 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-21The "trap" instruction is one of this which doesn't have a condition code. HackBill Wendling
the code to not add a "condition code" if it's trap. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119937 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-21- Give "trap" the correct encoding, at least according to Darwin's assembler.Bill Wendling
- Add comments saying where the encodings for other instructions came from. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119936 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-21apply Dan's fix for PR8268 which allows constant folding to handle indexes overChris Lattner
zero sized elements. This allows us to compile: #include <string> void foo() { std::string s; } into an empty function. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119933 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-21implement PR8524, apparently mainline gas accepts movq as an alias for movdChris Lattner

2010-11-21rework some DSE paths to use the newly-public "getPointerDependencyFrom"Chris Lattner
method in MemDep instead of inserting an instruction, doing a query, then removing it. Neither operation is effectively cached. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119930 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-21add "getLocation" method to AliasAnalysis for getting the source andChris Lattner
destination location of a memcpy/memmove. I'm not clear about whether TBAA works on these, so I'm leaving it out for now. Dan, please revisit this when convenient. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119928 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119917 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-21Implement PR8644: forwarding a memcpy value to a byval,Chris Lattner
allowing the memcpy to be eliminated. Unfortunately, the requirements on byval's without explicit alignment are really weak and impossible to predict in the mid-level optimizer, so this doesn't kick in much with current frontends. The fix is to change clang to set alignment on all byval arguments. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119916 91177308-0d34-0410-b5e6-96231b3b80d8
