2004-05-11Include <sys/types.h> to get the definition of int64_t on Solaris.Brian Gaeke
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13456 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-10Switch this from using an std::map to using a DenseMap. This speeds upChris Lattner
phi-elimination from 0.6 to 0.54s on kc++. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13454 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-10Use a new VRegPHIUseCount to compute uses of PHI values by other phi valuesChris Lattner
in the basic block being processed. This fixes PhiElimination on kimwitu++ from taking 105s to taking a much more reasonable 0.6s (in a debug build). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13453 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-10Now that we use an ilist of machine instructions, iterators are more robustChris Lattner
than before. Because this is the case, we can compute the first non-phi instruction once when de-phi'ing a block. This shaves ~4s off of phielimination of _Z7yyparsev in kimwitu++ from 109s -> 105s. There are still much more important gains to come. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13452 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-10Fix a fairly serious pessimizaion that was preventing us from efficientlyChris Lattner
compiling things like 'add long %X, 1'. The problem is that we were switching the order of the operands for longs even though we can't fold them yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13451 91177308-0d34-0410-b5e6-96231b3b80d8

2004-05-10Patch to fix PR337. Make sure to mark all aliased physical registers as usedChris Lattner
when we see a read of a register. This is important in cases like: AL = ... AH = ... = AX The read of AX must make both the AL and AH defs live until the use. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13444 91177308-0d34-0410-b5e6-96231b3b80d8

2004-05-09Changes to make the Stacker Stack use 64 bit values. This *should* getReid Spencer
around the problem with Stacker on Solaris because the Stack can handle 64-bit entries (pointer sized). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13441 91177308-0d34-0410-b5e6-96231b3b80d8

2004-05-09syntactically loopify natural loops so that the GCC loop optimizer can find ↵Chris Lattner
them. This should *dramatically* improve the performance of CBE compiled code on targets that depend on GCC's loop optimizations (like PPC) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13438 91177308-0d34-0410-b5e6-96231b3b80d8

2004-05-08Add support for widening integral casts.Brian Gaeke
Flesh out the SetCC support... which currently ends in a little bit of unfinished code (which is probably completely hilarious) for generating the condition value splitting the basic block up into 4 blocks, like this (clearly a better API is needed for this!): BB cond. branch / / R1=1 R2=0 \ / \ / R=phi(R1,R2) Other minor edits. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13423 91177308-0d34-0410-b5e6-96231b3b80d8

2004-05-08Add stub support for GEPs.Brian Gaeke
Add support for branches (based loosely on X86/InstSelectSimple). Add support for not visiting phi nodes in the first pass. Add support for loading bools. Flesh out support for stores. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13418 91177308-0d34-0410-b5e6-96231b3b80d8

2004-05-07Implement folding of GEP's like:Chris Lattner
%tmp.0 = getelementptr [50 x sbyte]* %ar, uint 0, int 5 ; <sbyte*> [#uses=2] %tmp.7 = getelementptr sbyte* %tmp.0, int 8 ; <sbyte*> [#uses=1] together. This patch actually allows us to simplify and generalize the code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13415 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-07Allow the user to set the LLVMINTERP environment variable as a workaround, forBrian Gaeke
when they have to run a gccld shell script without having lli in their path. This is intended to address Bug 289. Also, emit the traditional syntax ${1+"$@"} for passing all of a shell script's args to a subprocess. If you have arguments that have spaces in them, $* will not preserve the quoting (i.e., the quoted string "foo bar" as an argument will end up as two arguments "foo" "bar" to lli.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13414 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-07Add support for copying bool constants to registers.Brian Gaeke
Disable the code that copies long constants to registers - it looks fishy. Implement some simple casts: integral, smaller than longs, and equal-width or narrowing only. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13413 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-07Codegen floating point stores of constants into integer instructions. ThisChris Lattner
allows us to compile: store float 10.0, float* %P into: mov DWORD PTR [%EAX], 1092616192 instead of: .CPItest_0: # float 0x4024000000000000 .long 1092616192 # float 10 ... fld DWORD PTR [.CPItest_0] fstp DWORD PTR [%EAX] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13409 91177308-0d34-0410-b5e6-96231b3b80d8

2004-05-07Make comparisons against the null pointer as efficient as integer comparisonsChris Lattner
against zero. In particular, don't emit: mov %ESI, 0 cmp %ECX, %ESI instead, emit: test %ECX, %ECX git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13407 91177308-0d34-0410-b5e6-96231b3b80d8
