2011-04-18malloc elimination: it's a bad idea to use raw_svector_ostream on aEli Friedman
small heap-allocated SmallString because it unconditionally forces a malloc. (Revised version of r129688, with the necessary flush() call.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129716 91177308-0d34-0410-b5e6-96231b3b80d8

2011-04-18Fix a bug where we were counting the alias sets as completely usedEric Christopher
registers for fast allocation a different way. This has us updating used registers only when we're using that exact register. Fixes rdar://9207598 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129711 91177308-0d34-0410-b5e6-96231b3b80d8

2011-04-18Add a new bit that ImmLeaf's can opt into, which allows them to duck out ofChris Lattner
the generated FastISel. X86 doesn't need to generate code to match ADD16ri8 since ADD16ri will do just fine. This is a small codesize win in the generated instruction selector. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129692 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-18Implement major new fastisel functionality: the matcher can now handle ↵Chris Lattner
immediates with value constraints on them (when defined as ImmLeaf's). This is particularly important for X86-64, where almost all reg/imm instructions take a i64immSExt32 immediate operand, which has a value constraint. Before this patch we ended up iseling the examples into such amazing code as: movabsq $7, %rax imulq %rax, %rdi movq %rdi, %rax ret now we produce: imulq $7, %rdi, %rax ret This dramatically shrinks the generated code at -O0 on x86-64. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129691 91177308-0d34-0410-b5e6-96231b3b80d8

2011-04-17introduce a new OpKind abstraction which wraps up operand flavors in a tidy ↵Chris Lattner
little wrapper. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129680 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-17change OperandsSignature to use SmallVector<char> instead of std::vector<string>Chris Lattner
since the strings are always exactly one character, and there are usually only 2-3 operands. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129678 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-17since the VT is fixed for a ImmLeaf, there is no reason to expose it to the ↵Chris Lattner

2011-04-17switch the rest of the x86 immediate patterns over to ImmLeaf, Chris Lattner
simplifying them and exposing more information to tblgen. It would be nice if other target authors adopted this as well, particularly arm since it has fastisel. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129676 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-17now that predicates have a decent abstraction layer on them, introduce a new Chris Lattner
kind of predicate: one that is specific to imm nodes. The predicate function specified here just checks an int64_t directly instead of messing around with SDNode's. The virtue of this is that it means that fastisel and other things can reason about these predicates. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129675 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-17Rework our internal representation of node predicates to expose moreChris Lattner
structure and fix some fixmes. We now have a TreePredicateFn class that handles all of the decoding of these things. This is an internal cleanup that has no impact on the code generated by tblgen. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129670 91177308-0d34-0410-b5e6-96231b3b80d8

2011-04-171. merge fast-isel-shift-imm.ll into fast-isel-x86-64.llChris Lattner
2. implement rdar://9289501 - fast isel should fold trivial multiplies to shifts 3. teach tblgen to handle shift immediates that are different sizes than the shifted operands, eliminating some code from the X86 fast isel backend. 4. Have FastISel::SelectBinaryOp use (the poorly named) FastEmit_ri_ function instead of FastEmit_ri to simplify code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129666 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-17fix an x86 fast isel issue where we'd completely give up on folding an addressChris Lattner
when we have a global variable base an an index. Instead, just give up on folding the global variable. Before we'd geenrate: _test: ## @test ## BB#0: movq _rtx_length@GOTPCREL(%rip), %rax leaq (%rax), %rax addq %rdi, %rax movzbl (%rax), %eax ret now we generate: _test: ## @test ## BB#0: movq _rtx_length@GOTPCREL(%rip), %rax movzbl (%rax,%rdi), %eax ret The difference is even more significant when there is a scale involved. This fixes rdar://9289558 - total fail with addr mode formation at -O0/x86-64 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129664 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-17fix an oversight which caused us to compile the testcase (and otherChris Lattner
less trivial things) into a dummy lea. Before we generated: _test: ## @test movq _G@GOTPCREL(%rip), %rax leaq (%rax), %rax ret now we produce: _test: ## @test movq _G@GOTPCREL(%rip), %rax ret This is part of rdar://9289558 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129662 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-17tidy up and reduce indentation.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129661 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-17Fix rdar://9289512 - not folding load into compare at -O0Chris Lattner
The basic issue here is that bottom-up isel is matching the branch and compare, and was failing to fold the load into the branch/compare combo. Fixing this (by allowing folding into any instruction of a sequence that is selected) allows us to produce things like: cmpb $0, 52(%rax) je LBB4_2 instead of: movb 52(%rax), %cl cmpb $0, %cl je LBB4_2 This makes the generated -O0 code run a bit faster, but also speeds up compile time by putting less pressure on the register allocator and generating less code. This was one of the biggest classes of missing load folding. Implementing this shrinks 176.gcc's c-decl.s (as a random example) by about 4% in (verbose-asm) line count. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129656 91177308-0d34-0410-b5e6-96231b3b80d8
