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
2004-05-07Add more casts. You can never have enough casts.Brian Gaeke

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

2004-05-06Use the new commandline flag to allow us to call bugpoint like this:Chris Lattner
bugpoint ... --tool-args -enable-correct-eh-support -regalloc=linearscan --args -- -foo So that tool-args option gets the -enable-correct-eh-support -regalloc=linearscan flags instead of bugpoint. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13389 91177308-0d34-0410-b5e6-96231b3b80d8

2004-05-06Fix for PR#330.John Criswell
When looking at getelementptr instructions, make sure to use a forwarded type. We want to do this because a DerivedType may drop its uses and then refine its users, who may then use another user who hasn't been refined yet. By getting the forwarded type, we always ensure that we're looking at a Type that isn't in a halfway refined state. Now, I should be able to put this stuff in PATypeHandle, but it doesn't work for some reason. This should do for now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13386 91177308-0d34-0410-b5e6-96231b3b80d8

2004-05-05Move the stuff that fixes the size, orientation & fonts of graphs toBrian Gaeke
the debugging functions that call "dot". These fixed settings have various problems: for example, the fixed size that is set in the graph traits classes is not appropriate for turning the dot file into a PNG, and if TrueType font rendering is being used, the 'Courier' TrueType font may not be installed. It seems easy enough to specify these things on the command line, anyhow. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13366 91177308-0d34-0410-b5e6-96231b3b80d8
