Hi, On the hexagon target, I have written a following combiner pattern. ********************************************* def: Pat<(i64 (or (i64 (shl (i64 (extloadi32 (i32 (add IntRegs:$src1, s11_2ExtPred:$offset1)))), (i32 32))), (i64 (zextloadi32 ADDRriS11_2:$src2)))), (i64 (COMBINE_rr

Hi, I am observing some incorrect behavior in basicaa, wherein two pointers that basicaa should determine to be MustAlias are ending up NoAlias - the other extreme :( I am blaming this on basicaa not handling inttoptr. Here is the relevant IR snippet. -------------------- %sunkaddr36 = ptrtoint %struct.BitParams* %bs to i32 %sunkaddr37 = add i32 %sunkaddr36, 16 %sunkaddr38 = inttoptr i32

Hi, I have three constants (B, C and V) and V = B + C. I want to find out if B + C wraps around. The way I'll do it is, assuming B and C are both positive, to check if V < B or C. For this I need the values of B, C and V. I tried using APInt as below. *** If (isa<Constant> (B) && isa<Constant> (C) && isa<Constant>(V)) { ConstantInt *CV =

Hi, I have been trying to use the -mllvm -debug option for clang but without much success. Do I need to build in any specific manner for this to work ? On using -mllvm -debug as follows I get the error below. $>clang -ccc-host-triple armv7-none-linux-gnueabi -mfloat-abi=softfp -mfpu=neon -mcpu=cortex-a9 -mllvm -debug fdct.i -S clang (LLVM option parsing): Unknown command line argument

Hi, I wanted to see the non-debug uses of register 0 (Noreg) and so, I wrote the following piece of code. ***** MRI = &MF.getRegInfo(); if (!MRI->use_nodbg_empty(0)) { for (MachineRegisterInfo::use_nodbg_iterator ri = MRI->use_nodbg_begin(0), re = MRI->use_nodbg_end(); ri != re; ++ri) { MachineInstr *UseMI = &*ri; UseMI->dump ();
