From the summary docs, we are emitting LD1D Zresult.D, Pg/Z, [Xbase, Zindices.D, LSL #3], which does not take xs field, so we do not have to embed UXTW or SXTW bit, right?

Correct

which does not take xs field, so we do not have to embed UXTW or SXTW bit, right?

Removing this, I get an asset (in emitarm64sve.cpp:6441). Looks like emit is expecting this field. I'll have to debug it a little more. There are a lot of different loads and I don't want to break any of them.

so you are saying that although we pass the *XTW flag, we are not using it in for this instruction, although the code path flows through the emitarm64sve.cpp that you mentioned?

Looks like it's using the flag to make a decision to decide on the correct encoding. Then doesn't use it later. Probably just needs a fix in emit.

Probably just needs a fix in emit.

Did you fix it in this PR?

Addressing modes now fixed. There are three variants for "address with vector of offsets":

Vector<64bit> GatherVector(Vector<64bit> mask, 64bit* address, Vector<64bit> indices)
-> LD1D Zresult.D, Pg/Z, [Xbase, Zindices.D, LSL #3]

Vector<32bit> GatherVector(Vector<32bit> mask, 32bit* address, Vector<signed32bit> indices)
-> LD1W Zresult.S, Pg/Z, [Xbase, Zindices.S, SXTW #2]

Vector<32bit> GatherVector(Vector<32bit> mask, 32bit* address, Vector<unsigned32bit> indices)
-> LD1W Zresult.S, Pg/Z, [Xbase, Zindices.S, UXTW #2]

Codegen now picks the correct ones
