[LLVMdev] Problem with "Does not dominate all uses"
...cond.true and cond.false, both of which branch unconditionally to cond.end. Therefore %6 dominates its use.
In your second file %18 is defined in end.11 and used in cond.end. However, end.11 no longer dominates cond.end because you have rewritten all branches to go through the switch statement in loopEntry, and it is possible to take the path from entry to loopEntry to cond.end without going through end.11.

[LLVMdev] help with pointer-to-array conversion
OK, thanks Chris, I've found that running
opt -loopsimplify -instcombine -indvars -stats
gives me the setup I need for this transformation, and a small patch
makes it happen in the simple case we discussed. However, I'm having
some trouble when things get a bit more complicated with 3 nesting levels:
int A[3000000], B[20000], C[100], Z;
int main()
{
int i, j, k, *a, *b,

[LLVMdev] RE: Question about Global Variable
...izer, i.e. "test str"
pGVars[0] = gStrA;
pGVars[1] = gStrB;
// change the content of gStrA
for(i=0;i<5;i++){
pGVars[0][i] ^= 0x27;
}
}
the following IR code is the loop part code which is corresponding to the above C code
no_exit: ; preds = %loopentry
%tmp.31 = getelementptr [3 x sbyte*]* %pGVars, int 0, int 0 ; <sbyte**> [#uses=1]
%tmp.32 = load sbyte** %tmp.31 ; <sbyte*> [#uses=1]
