</span>No vectors involved in this case though.<br>
<br>
I think it's a size vs stores size issue, possibly that might affect <br>
bigendian vectors too? I don't know.<br>

<br>
</span>When we reach getTruncatedStoreValue we have the following DAG:<br>
<br>
SelectionDAG has 22 nodes:<br>
t0: ch = EntryToken<br>
t2: i24,ch = CopyFromReg t0, Register:i24 %0<br>
t23: ch = TokenFactor t2:1, t22<br>
t32: i32 = srl t38, Constant:i16<16><br>
t17: ch,glue = CopyToReg t23, Register:i32 $a1_32, t32<br>
t27: i16 = add FrameIndex:i16<0>, Constant:i16<2><br>
t34: i32,ch = load<(dereferenceable load 1 from %ir._p48 + 2), <br>
zext from i16> t22, t27, undef:i16<br>
t30: i32 = shl t38, Constant:i16<16><br>
t37: i32 = add t34, t30<br>
t19: ch,glue = CopyToReg t17, Register:i32 $a0_32, t37, t17:1<br>
t24: i40 = any_extend t2<br>
t6: i40 = shl nuw t24, Constant:i16<16><br>
t22: ch = store<(store 3 into %ir._p40, align 1)> t0, t6, <br>
FrameIndex:i16<0>, undef:i16<br>
t38: i32,ch = load<(dereferenceable load 2 from %ir._p48, align 1)> <br>
t22, FrameIndex:i16<0>, undef:i16<br>
t20: ch = PHXISD::RETURN t19, Register:i32 $a1_32, Register:i32 <br>
$a0_32, t19:1<br>
<br>
and the following types<br>
<br>
STType: i40<br>
LDType: i32<br>
STMemType: i40<br>
LDMemType: i32<br>
<br>
The Offset is 0.<br>
<br>
Complicating factor: the byte size on my target is 16, not 8, so we've <br>
replaced the hardcoded 8 in "* 8" and "/ 8" with "bitsPerByte()" which <br>
in our case is 16 so the code looks like:<br>
<br>
bool STCoversLD =<br>
<span> BasePtrST.equalBaseIndex(Base<wbr>PtrLD, DAG, Offset) && (Offset >= 0) &&<br>
</span> (Offset * bitsPerByte() <= LDMemType.getSizeInBits()) &&<br>
(Offset * bitsPerByte() + LDMemType.getSizeInBits() <=<br>
STMemType.getSizeInBits());<br>
<br>
if (!STCoversLD)<br>
return SDValue();<br>
<br>
// Normalize for Endianness.<br>
if (DAG.getDataLayout().isBigEndi<wbr>an())<br>
Offset =<br>
(STMemType.getSizeInBits() - LDMemType.getSizeInBits()) /<br>
bitsPerByte() - Offset;<br>
<br>
The Offset was thus calculated as<br>
<br>
(40 - 32)/16 - 0<br>
<br>
which I suspect is incorrect.<br>
<br>
STMemType is i40, so the size in bits is 40. However, the store size for <br>
i40 is 48!<br>
<br>
So I think that we need to involve the store size in some way here.<br>
<br>
