Hi @kunalspathak , would you prefer an overloaded name for the interleaved multi-structure stores like we did for StoreSelectedScalar? If yes then what should we call such methods? Store or StoreVector may not convey the interleaving nature of underlying store instructions. 🤔

sorry, but could you confirm which APIs are you asking about?

The StoreVectorNX2, StoreVectorNx3, StoreVectorNx3 that result in ST2, ST3 and ST4 instructions respectively.

Hi @kunalspathak,

Could you please confirm if my understanding is correct?

  • LoadVector(N)x(M) is mapped to LD(M). E.g., LoadVector128x3 to LD3

  • StoreVector(N)x(M) should map to ST(M), E.g., StoreVector128x3 to ST3

  • StoreVector(N)x(M)AndZip should map to ST1 with M registers.

If this is correct, then aren't these names a little confusing?
LD2/3/4 would unzip/de-interleave while loading the input registers while LD1 will load given input vectors 2/3/4 consecutively.
Thus, wouldn't it make more sense for LoadVector(N)x(M) to emit LD1 with M input values and vice-versa for LoadVector(N)x(M)AndZip?

Looking carefully, yes, you are right. I swapped the two. I will send a PR to fix it. Thanks for spotting it.

As the #93223 taking longer, I'll mark this PR ready for review. If this can progress further quickly then we can merge this. I'll rebase/merge these changes wherever necessary.

Hi @kunalspathak , would you prefer an overloaded name for the interleaved multi-structure stores like we did for StoreSelectedScalar? If yes then what should we call such methods? Store or StoreVector may not convey the interleaving nature of underlying store instructions. 🤔

The StoreVectorNX2, StoreVectorNx3, StoreVectorNx3 that result in ST2, ST3 and ST4 instructions respectively.

Hi @kunalspathak,
Could you please confirm if my understanding is correct?
  • LoadVector(N)x(M) is mapped to LD(M). E.g., LoadVector128x3 to LD3
  • StoreVector(N)x(M) should map to ST(M), E.g., StoreVector128x3 to ST3
  • StoreVector(N)x(M)AndZip should map to ST1 with M registers.
If this is correct, then aren't these names a little confusing?

LD2/3/4 would unzip/de-interleave while loading the input registers while LD1 will load given input vectors 2/3/4 consecutively.

Thus, wouldn't it make more sense for LoadVector(N)x(M) to emit LD1 with M input values and vice-versa for LoadVector(N)x(M)AndZip?

Looking carefully, yes, you are right. I swapped the two. I will send a PR to fix it. Thanks for spotting it.

As the #93223 taking longer, I'll mark this PR ready for review. If this can progress further quickly then we can merge this. I'll rebase/merge these changes wherever necessary.

LGTM. Just a request to update the documentation for LoadVector equivalent.

Hi @kunalspathak , would you prefer an overloaded name for the interleaved multi-structure stores like we did for StoreSelectedScalar? If yes then what should we call such methods? Store or StoreVector may not convey the interleaving nature of underlying store instructions. 🤔

The StoreVectorNX2, StoreVectorNx3, StoreVectorNx3 that result in ST2, ST3 and ST4 instructions respectively.

Hi @kunalspathak,
Could you please confirm if my understanding is correct?
  • LoadVector(N)x(M) is mapped to LD(M). E.g., LoadVector128x3 to LD3
  • StoreVector(N)x(M) should map to ST(M), E.g., StoreVector128x3 to ST3
  • StoreVector(N)x(M)AndZip should map to ST1 with M registers.
If this is correct, then aren't these names a little confusing?

LD2/3/4 would unzip/de-interleave while loading the input registers while LD1 will load given input vectors 2/3/4 consecutively.

Thus, wouldn't it make more sense for LoadVector(N)x(M) to emit LD1 with M input values and vice-versa for LoadVector(N)x(M)AndZip?

Looking carefully, yes, you are right. I swapped the two. I will send a PR to fix it. Thanks for spotting it.

As the #93223 taking longer, I'll mark this PR ready for review. If this can progress further quickly then we can merge this. I'll rebase/merge these changes wherever necessary.

LGTM. Just a request to update the documentation for LoadVector equivalent.

Hi @kunalspathak , would you prefer an overloaded name for the interleaved multi-structure stores like we did for StoreSelectedScalar? If yes then what should we call such methods? Store or StoreVector may not convey the interleaving nature of underlying store instructions. 🤔

The StoreVectorNX2, StoreVectorNx3, StoreVectorNx3 that result in ST2, ST3 and ST4 instructions respectively.

Hi @kunalspathak,
Could you please confirm if my understanding is correct?
  • LoadVector(N)x(M) is mapped to LD(M). E.g., LoadVector128x3 to LD3
  • StoreVector(N)x(M) should map to ST(M), E.g., StoreVector128x3 to ST3
  • StoreVector(N)x(M)AndZip should map to ST1 with M registers.
If this is correct, then aren't these names a little confusing?

LD2/3/4 would unzip/de-interleave while loading the input registers while LD1 will load given input vectors 2/3/4 consecutively.

Thus, wouldn't it make more sense for LoadVector(N)x(M) to emit LD1 with M input values and vice-versa for LoadVector(N)x(M)AndZip?

Looking carefully, yes, you are right. I swapped the two. I will send a PR to fix it. Thanks for spotting it.

As the #93223 taking longer, I'll mark this PR ready for review. If this can progress further quickly then we can merge this. I'll rebase/merge these changes wherever necessary.

Hi @kunalspathak , would you prefer an overloaded name for the interleaved multi-structure stores like we did for StoreSelectedScalar? If yes then what should we call such methods? Store or StoreVector may not convey the interleaving nature of underlying store instructions. 🤔

The StoreVectorNX2, StoreVectorNx3, StoreVectorNx3 that result in ST2, ST3 and ST4 instructions respectively.

Hi @kunalspathak,
Could you please confirm if my understanding is correct?
  • LoadVector(N)x(M) is mapped to LD(M). E.g., LoadVector128x3 to LD3
  • StoreVector(N)x(M) should map to ST(M), E.g., StoreVector128x3 to ST3
  • StoreVector(N)x(M)AndZip should map to ST1 with M registers.
If this is correct, then aren't these names a little confusing?

LD2/3/4 would unzip/de-interleave while loading the input registers while LD1 will load given input vectors 2/3/4 consecutively.

Thus, wouldn't it make more sense for LoadVector(N)x(M) to emit LD1 with M input values and vice-versa for LoadVector(N)x(M)AndZip?

Looking carefully, yes, you are right. I swapped the two. I will send a PR to fix it. Thanks for spotting it.

Hi @kunalspathak,
Could you please confirm if my understanding is correct?
  • LoadVector(N)x(M) is mapped to LD(M). E.g., LoadVector128x3 to LD3
  • StoreVector(N)x(M) should map to ST(M), E.g., StoreVector128x3 to ST3
  • StoreVector(N)x(M)AndZip should map to ST1 with M registers.
If this is correct, then aren't these names a little confusing?

LD2/3/4 would unzip/de-interleave while loading the input registers while LD1 will load given input vectors 2/3/4 consecutively.

Thus, wouldn't it make more sense for LoadVector(N)x(M) to emit LD1 with M input values and vice-versa for LoadVector(N)x(M)AndZip?

Hi @kunalspathak , would you prefer an overloaded name for the interleaved multi-structure stores like we did for StoreSelectedScalar? If yes then what should we call such methods? Store or StoreVector may not convey the interleaving nature of underlying store instructions. 🤔

Hi @kunalspathak , would you prefer an overloaded name for the interleaved multi-structure stores like we did for StoreSelectedScalar? If yes then what should we call such methods? Store or StoreVector may not convey the interleaving nature of underlying store instructions. 🤔

The StoreVectorNX2, StoreVectorNx3, StoreVectorNx3 that result in ST2, ST3 and ST4 instructions respectively.

Hi @kunalspathak,
Could you please confirm if my understanding is correct?
  • LoadVector(N)x(M) is mapped to LD(M). E.g., LoadVector128x3 to LD3
  • StoreVector(N)x(M) should map to ST(M), E.g., StoreVector128x3 to ST3
  • StoreVector(N)x(M)AndZip should map to ST1 with M registers.
If this is correct, then aren't these names a little confusing?

LD2/3/4 would unzip/de-interleave while loading the input registers while LD1 will load given input vectors 2/3/4 consecutively.

Thus, wouldn't it make more sense for LoadVector(N)x(M) to emit LD1 with M input values and vice-versa for LoadVector(N)x(M)AndZip?

Looking carefully, yes, you are right. I swapped the two. I will send a PR to fix it. Thanks for spotting it.

As the #93223 taking longer, I'll mark this PR ready for review. If this can progress further quickly then we can merge this. I'll rebase/merge these changes wherever necessary.
