2009-04-02To convert the StopPoint insn into an assembler directive by ISel, we need ↵Sanjiv Gupta
to have access to the line number field. So we convert that info as an operand by custom handling DBG_STOPPOINT in legalize. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68329 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-02Params are not being generated as static globals now. The caller passes them ↵Sanjiv Gupta
onto the callee's stack directly and the callee loads the argvals from its own stack. Clang generated frameindexes validatd by recalculating the stack as if all frameindexes represent 1-byte slots. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68327 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-01Add llvm::Triple class for abstracting access to target triples.Daniel Dunbar
- The code is silly, I'm just amusing myself. Rewrite to be efficient if you like. :) Also, if you wish to debate the proper names of the triple components I'm all ears. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68252 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-31Make the key of ValueRankMap an AssertingVH, so that we die violentlyChris Lattner
if it dangles. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68150 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-31Add two new classes: WeakVH and AssertingVH. These are both "ValueHandles", Chris Lattner
which are effectively smart pointers to Value*'s. They are both very light weight and simple, and react to values being destroyed or being RAUW'd. WeakVN does a best effort to follow a value around, including through RAUW operations and will get nulled out of the value is destroyed. This is useful for the eventual "metadata that references a value" work, because it is a reference to a value that does not show up on its use_* list. AssertingVH is a pointer that compiles down to a dumb raw pointer when assertions are disabled. When enabled, it emits an assertion if the pointed-to value is destroyed while it is still being referenced. This is very useful for Maps and other things, and should have caught the recent bugs in CallGraph and Reassociate, for example. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68149 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-31Throttle back "fold select into operand" transformation. InstCombine should ↵Evan Cheng
not generate selects of two constants unless they are selects of 0 and 1. e.g. define i32 @t1(i32 %c, i32 %x) nounwind { %t1 = icmp eq i32 %c, 0 %t2 = lshr i32 %x, 18 %t3 = select i1 %t1, i32 %t2, i32 %x ret i32 %t3 } was turned into define i32 @t2(i32 %c, i32 %x) nounwind { %t1 = icmp eq i32 %c, 0 %t2 = select i1 %t1, i32 18, i32 0 %t3 = lshr i32 %x, %t2 ret i32 %t3 } For most targets, that means materializing two constants and then a select. e.g. On x86-64 movl %esi, %eax shrl $18, %eax testl %edi, %edi cmovne %esi, %eax ret => xorl %eax, %eax testl %edi, %edi movl $18, %ecx cmovne %eax, %ecx movl %esi, %eax shrl %cl, %eax ret Also, the optimizer and codegen can reason about shl / and / add, etc. by a constant. This optimization will hinder optimizations using ComputeMaskedBits. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68142 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-31Add llvm::sys::getHostTriple and removeDaniel Dunbar
llvm::sys::getOS{Name,Version}. Right now the implementation just derives from LLVM_HOSTTRIPLE (which is wrong, but it doesn't look like we have a define for the target triple). Ideally this routine would actually be able to compute the triple for targets we care about. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68118 91177308-0d34-0410-b5e6-96231b3b80d8
