Chris Lattner 60ef22da3d Testcase for PR337, which was reduced by Reid Spencer.

Reid Spencer 45e25d8295 Bug 178 Fixed 
llvm-svn: 13442
 2004-05-09 23:32:39 +00:00
Reid Spencer be4fadf1b8 Changes to make the Stacker Stack use 64 bit values. This *should* get 
around the problem with Stacker on Solaris because the Stack can handle
64-bit entries (pointer sized).

Chris Lattner a367dd745b Fix some comments, avoid sign extending booleans when zero extend works fine

Chris Lattner f719a52088 syntactically loopify natural loops so that the GCC loop optimizer can find them. This should *dramatically* improve the performance of CBE compiled code on targets that depend on GCC's loop optimizations (like PPC)

Chris Lattner 9c29991970 Make the floating point constant pools local to each function, split the 
FindUsedTypes manipulation stuff out to be a seperate pass, and make the
main CWriter be a function pass now!

Brian Gaeke 1096ba9422 Add support for widening integral casts. 
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.

Chris Lattner 5f667a6f58 Implement folding of GEP's like: 
%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.

Brian Gaeke 9a7b9d07f0 Allow the user to set the LLVMINTERP environment variable as a workaround, for 
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.)

Brian Gaeke 584308b71a Add support for copying bool constants to registers. 
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.

Chris Lattner a2dc6bf6e6 Codegen floating point stores of constants into integer instructions. This 
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]

 2004-05-07 21:10:28 +00:00
Chris Lattner cecf3f94a4 Make comparisons against the null pointer as efficient as integer comparisons 
against zero.  In particular, don't emit:

        mov %ESI, 0
        cmp %ECX, %ESI

instead, emit:

       test %ECX, %ECX

 2004-05-06 22:15:47 +00:00
Chris Lattner 6aee736d1b Use the new commandline flag to allow us to call bugpoint like this: 
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.

John Criswell f6709bc579 Fix for PR#330. 
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.
