Chris Lattner 66e6a8229a This is the first major step of implementing PR1226. We now successfully 
scalarrepl things down to elements, but mem2reg can't promote elements that
are memset/memcpy'd.  Until then, the code is disabled "0 &&".

Chris Lattner 5fdded1d2f Add some simplifications for demanded bits, this allows instcombine to turn: 
define i64 @test(i64 %A, i32 %B) {
        %tmp12 = zext i32 %B to i64             ; <i64> [#uses=1]
        %tmp3 = shl i64 %tmp12, 32              ; <i64> [#uses=1]
        %tmp5 = add i64 %tmp3, %A               ; <i64> [#uses=1]
        %tmp6 = and i64 %tmp5, 123              ; <i64> [#uses=1]
        ret i64 %tmp6
}

into:

define i64 @test(i64 %A, i32 %B) {
        %tmp6 = and i64 %A, 123         ; <i64> [#uses=1]
        ret i64 %tmp6
}

This implements Transforms/InstCombine/add2.ll:test1

 2007-03-04 20:08:45 +00:00
Chris Lattner e2e13caeb2 canonicalize constants to the RHS of addc/adde. If nothing uses the carry out of 
addc, turn it into add.

This allows us to compile:

long long test(long long A, unsigned B) {
  return (A + ((long long)B << 32)) & 123;
}

into:

_test:
        movl $123, %eax
        andl 4(%esp), %eax
        xorl %edx, %edx
        ret

instead of:
_test:
        xorl %edx, %edx
        movl %edx, %eax
        addl 4(%esp), %eax   ;; add of zero
        andl $123, %eax
        ret

 2007-03-04 04:04:43 +00:00
Chris Lattner d7b4c92cd0 make better use of LCSSA information in RewriteLoopExitValues. Before, we 
would scan the entire loop body, then scan all users of instructions in the
loop, looking for users outside the loop.  Now, since we know that the
loop is in LCSSA form, we know that any users outside the loop will be LCSSA
phi nodes.  Just scan them.

This speeds up indvars significantly.

Chris Lattner 1f7648efba Implement PR1179/PR1232 and test/Transforms/IndVarsSimplify/loop_evaluate_[234].ll 
This makes -indvars require and use LCSSA, updating it as appropriate.

Reid Spencer 04a1829559 Remove unnecessary #include. 
llvm-svn: 34889
 2007-03-03 18:29:16 +00:00
Reid Spencer e586f2e7f7 1. Handle errors around the ModuleProvider. This is necessary since it is 
reading bytecode.
2. The interpreter can delete the ModuleProvider and replace it with
   another so don't depend on it being around after the EE is created.
3. Don't just run llvm_shutdown on exit but actually delete the EE as well.
   This cleans up a vast amount of memory (but not all) that EE retained
   through exit.

Reid Spencer 603682ad1d Deal with error handling better. 
llvm-svn: 34887
 2007-03-03 18:19:18 +00:00
Reid Spencer 30ed3bdaf2 Make the creation functions take an error string. This will help the 
ExecutionEngine report errors on creation (like bytecode stuff) and also
help to get rid of exception handling.

Reid Spencer 1f87660d29 Make sure that when we store a value it is masked to its correct bit 
width. This helps CBE work with non-standard integer bit widths.

Reid Spencer ec8c51c1b1 Complete the APIntification of the interpreter. All asserts for > 64 bits

destination value of LoadValueFromMemory.

llvm-svn: 34883
