Could you confirm why were so many files changed using jit-format? All the files are formatted as needed already.

[kunalspathak]

Probably worth adding a line of comment that further moves are not possible using YMM and so we will try XMM.

[alexcovington]

Yes, good point. I'll add a note.

[alexcovington]

@kunalspathak The large number of JIT changes happened after I ran jit-format, but I think something may have been wrong with my version of jit-format as it kept failing CI/CD. Reverted those commits and re-ran with a known good version of jit-format, hopefully that resolves the issue.

[kunalspathak]

Looks much better.

[kunalspathak]

@tannergooding - in case you want to take another look.

[kunalspathak]

Also, could you please share the superpmi asmdiff numbers just to make sure that there are no surprise regressions introduced because this will get ported to .NET 6

[alexcovington]

@kunalspathak Here are the asm diffs:

Looks like the bigger regressions are caused by having to initialize both SIMD and GPR registers. Here's an example:

libraries.crossgen2.windows.x64.checked.mch

53165.asm

Baseline

xorpsxmm0,xmm0movups xmmword ptr [rsp+2B10H],xmm0movups xmmword ptr [rsp+2B18H],xmm0

Diff

xorecx,ecxxorpsxmm0,xmm0movups xmmword ptr [rsp+2B10H],xmm0mov qword ptr [rsp+2B20H],rcx

[tannergooding]

LGTM.

I'm a bit surprised this had shown up as a pipeline stall, however. Backtracking and doing a "misaligned" write is fairly common practice. Even Windows x64 memcpy does this for 16-32 byte blocks.

[kunalspathak]

I did asmdiff with this change on my local machine and seems most of the regression is because having to do copies for size < 16 or we add additional GPR moves and stop doing unaligned copies.

It seems that it just erases the previous improvements introduced in #55604 while still taking care of the regression. Below are the diffs if I revert your change in #55604 vs. the PR for benchmarks windows/x64.

Summary of Code Size diffs:

I see, that's a better example of what is regressing. Let me know if there is anything else needed for this PR, thanks for all the support!

[kunalspathak]

Failures seems to be related to #59541

[kunalspathak]

Some regressions that are possibly related to this change: dotnet/perf-autofiling-issues#1603
@alexcovington - can you just double check?

[alexcovington]

@kunalspathak I will double check and update with any findings.

[kunalspathak]

Also - dotnet/perf-autofiling-issues#1591

[alexcovington]

Doesn't look like this change is related since none of the regressions appear to be generating block inits/copies.

Could you confirm why were so many files changed using jit-format? All the files are formatted as needed already.

[kunalspathak]

Probably worth adding a line of comment that further moves are not possible using YMM and so we will try XMM.

[alexcovington]

Yes, good point. I'll add a note.

[alexcovington]

@kunalspathak The large number of JIT changes happened after I ran jit-format, but I think something may have been wrong with my version of jit-format as it kept failing CI/CD. Reverted those commits and re-ran with a known good version of jit-format, hopefully that resolves the issue.

[kunalspathak]

Looks much better.

[kunalspathak]

@tannergooding - in case you want to take another look.

[kunalspathak]

Also, could you please share the superpmi asmdiff numbers just to make sure that there are no surprise regressions introduced because this will get ported to .NET 6

[alexcovington]

@kunalspathak Here are the asm diffs:

Looks like the bigger regressions are caused by having to initialize both SIMD and GPR registers. Here's an example:

libraries.crossgen2.windows.x64.checked.mch

53165.asm

Baseline

xorpsxmm0,xmm0movups xmmword ptr [rsp+2B10H],xmm0movups xmmword ptr [rsp+2B18H],xmm0

Diff

xorecx,ecxxorpsxmm0,xmm0movups xmmword ptr [rsp+2B10H],xmm0mov qword ptr [rsp+2B20H],rcx

[tannergooding]

LGTM.

I'm a bit surprised this had shown up as a pipeline stall, however. Backtracking and doing a "misaligned" write is fairly common practice. Even Windows x64 memcpy does this for 16-32 byte blocks.

[kunalspathak]

I did asmdiff with this change on my local machine and seems most of the regression is because having to do copies for size < 16 or we add additional GPR moves and stop doing unaligned copies.

It seems that it just erases the previous improvements introduced in #55604 while still taking care of the regression. Below are the diffs if I revert your change in #55604 vs. the PR for benchmarks windows/x64.

Summary of Code Size diffs:

Total bytes of base: 539149
Total bytes of diff: 522234
Total bytes of delta: -16915 (-3.14% of base)
Total relative delta: -32.88
diff is an improvement.
relative diff is an improvement.

I see, that's a better example of what is regressing. Let me know if there is anything else needed for this PR, thanks for all the support!

[kunalspathak]

Failures seems to be related to #59541

[kunalspathak]

Some regressions that are possibly related to this change: dotnet/perf-autofiling-issues#1603
@alexcovington - can you just double check?

[alexcovington]

@kunalspathak I will double check and update with any findings.

[kunalspathak]

Also - dotnet/perf-autofiling-issues#1591

[alexcovington]

Doesn't look like this change is related since none of the regressions appear to be generating block inits/copies.

Could you confirm why were so many files changed using jit-format? All the files are formatted as needed already.

[kunalspathak]

Probably worth adding a line of comment that further moves are not possible using YMM and so we will try XMM.

[alexcovington]

Yes, good point. I'll add a note.

[alexcovington]

@kunalspathak The large number of JIT changes happened after I ran jit-format, but I think something may have been wrong with my version of jit-format as it kept failing CI/CD. Reverted those commits and re-ran with a known good version of jit-format, hopefully that resolves the issue.

[kunalspathak]

Looks much better.

[kunalspathak]

@tannergooding - in case you want to take another look.

[kunalspathak]

Also, could you please share the superpmi asmdiff numbers just to make sure that there are no surprise regressions introduced because this will get ported to .NET 6

[alexcovington]

@kunalspathak Here are the asm diffs:

Looks like the bigger regressions are caused by having to initialize both SIMD and GPR registers. Here's an example:

libraries.crossgen2.windows.x64.checked.mch

53165.asm

Baseline

xorpsxmm0,xmm0movups xmmword ptr [rsp+2B10H],xmm0movups xmmword ptr [rsp+2B18H],xmm0

Diff

xorecx,ecxxorpsxmm0,xmm0movups xmmword ptr [rsp+2B10H],xmm0mov qword ptr [rsp+2B20H],rcx

[tannergooding]

LGTM.

I'm a bit surprised this had shown up as a pipeline stall, however. Backtracking and doing a "misaligned" write is fairly common practice. Even Windows x64 memcpy does this for 16-32 byte blocks.

[kunalspathak]

I did asmdiff with this change on my local machine and seems most of the regression is because having to do copies for size < 16 or we add additional GPR moves and stop doing unaligned copies.

It seems that it just erases the previous improvements introduced in #55604 while still taking care of the regression. Below are the diffs if I revert your change in #55604 vs. the PR for benchmarks windows/x64.

I see, that's a better example of what is regressing. Let me know if there is anything else needed for this PR, thanks for all the support!

[kunalspathak]

Failures seems to be related to #59541

[kunalspathak]

Some regressions that are possibly related to this change: dotnet/perf-autofiling-issues#1603
@alexcovington - can you just double check?

[alexcovington]

@kunalspathak I will double check and update with any findings.

[kunalspathak]

Also - dotnet/perf-autofiling-issues#1591

[alexcovington]

Doesn't look like this change is related since none of the regressions appear to be generating block inits/copies.

Could you confirm why were so many files changed using jit-format? All the files are formatted as needed already.

[kunalspathak]

Probably worth adding a line of comment that further moves are not possible using YMM and so we will try XMM.

[alexcovington]

Yes, good point. I'll add a note.

[alexcovington]

@kunalspathak The large number of JIT changes happened after I ran jit-format, but I think something may have been wrong with my version of jit-format as it kept failing CI/CD. Reverted those commits and re-ran with a known good version of jit-format, hopefully that resolves the issue.

[kunalspathak]

Looks much better.

[kunalspathak]

@tannergooding - in case you want to take another look.

[kunalspathak]

Also, could you please share the superpmi asmdiff numbers just to make sure that there are no surprise regressions introduced because this will get ported to .NET 6

[alexcovington]

@kunalspathak Here are the asm diffs:

Looks like the bigger regressions are caused by having to initialize both SIMD and GPR registers. Here's an example:

libraries.crossgen2.windows.x64.checked.mch

53165.asm

Baseline

xorpsxmm0,xmm0movups xmmword ptr [rsp+2B10H],xmm0movups xmmword ptr [rsp+2B18H],xmm0

Diff

xorecx,ecxxorpsxmm0,xmm0movups xmmword ptr [rsp+2B10H],xmm0mov qword ptr [rsp+2B20H],rcx

[tannergooding]

LGTM.

I'm a bit surprised this had shown up as a pipeline stall, however. Backtracking and doing a "misaligned" write is fairly common practice. Even Windows x64 memcpy does this for 16-32 byte blocks.

[kunalspathak]

I did asmdiff with this change on my local machine and seems most of the regression is because having to do copies for size < 16 or we add additional GPR moves and stop doing unaligned copies.

It seems that it just erases the previous improvements introduced in #55604 while still taking care of the regression. Below are the diffs if I revert your change in #55604 vs. the PR for benchmarks windows/x64.

I see, that's a better example of what is regressing. Let me know if there is anything else needed for this PR, thanks for all the support!

[kunalspathak]

Failures seems to be related to #59541

[kunalspathak]

Some regressions that are possibly related to this change: dotnet/perf-autofiling-issues#1603
@alexcovington - can you just double check?

[alexcovington]

@kunalspathak I will double check and update with any findings.

[kunalspathak]

Also - dotnet/perf-autofiling-issues#1591

[alexcovington]

Doesn't look like this change is related since none of the regressions appear to be generating block inits/copies.

Could you confirm why were so many files changed using jit-format? All the files are formatted as needed already.

[kunalspathak]

Probably worth adding a line of comment that further moves are not possible using YMM and so we will try XMM.

[alexcovington]

Yes, good point. I'll add a note.

[alexcovington]

@kunalspathak The large number of JIT changes happened after I ran jit-format, but I think something may have been wrong with my version of jit-format as it kept failing CI/CD. Reverted those commits and re-ran with a known good version of jit-format, hopefully that resolves the issue.

[kunalspathak]

Looks much better.

[kunalspathak]

@tannergooding - in case you want to take another look.

[kunalspathak]

Also, could you please share the superpmi asmdiff numbers just to make sure that there are no surprise regressions introduced because this will get ported to .NET 6

[alexcovington]

@kunalspathak Here are the asm diffs:

Looks like the bigger regressions are caused by having to initialize both SIMD and GPR registers. Here's an example:

libraries.crossgen2.windows.x64.checked.mch

53165.asm

Baseline

xorpsxmm0,xmm0movups xmmword ptr [rsp+2B10H],xmm0movups xmmword ptr [rsp+2B18H],xmm0

Diff

xorecx,ecxxorpsxmm0,xmm0movups xmmword ptr [rsp+2B10H],xmm0mov qword ptr [rsp+2B20H],rcx

[tannergooding]

LGTM.

I'm a bit surprised this had shown up as a pipeline stall, however. Backtracking and doing a "misaligned" write is fairly common practice. Even Windows x64 memcpy does this for 16-32 byte blocks.

[kunalspathak]

I did asmdiff with this change on my local machine and seems most of the regression is because having to do copies for size < 16 or we add additional GPR moves and stop doing unaligned copies.

It seems that it just erases the previous improvements introduced in #55604 while still taking care of the regression. Below are the diffs if I revert your change in #55604 vs. the PR for benchmarks windows/x64.

I see, that's a better example of what is regressing. Let me know if there is anything else needed for this PR, thanks for all the support!

[kunalspathak]

Failures seems to be related to #59541

[kunalspathak]

Some regressions that are possibly related to this change: dotnet/perf-autofiling-issues#1603
@alexcovington - can you just double check?

[alexcovington]

@kunalspathak I will double check and update with any findings.

[kunalspathak]

Also - dotnet/perf-autofiling-issues#1591

[alexcovington]

Doesn't look like this change is related since none of the regressions appear to be generating block inits/copies.

Could you confirm why were so many files changed using jit-format? All the files are formatted as needed already.

[kunalspathak]

Probably worth adding a line of comment that further moves are not possible using YMM and so we will try XMM.

[alexcovington]

Yes, good point. I'll add a note.

[alexcovington]

@kunalspathak The large number of JIT changes happened after I ran jit-format, but I think something may have been wrong with my version of jit-format as it kept failing CI/CD. Reverted those commits and re-ran with a known good version of jit-format, hopefully that resolves the issue.

[kunalspathak]

Looks much better.

[kunalspathak]

@tannergooding - in case you want to take another look.

[kunalspathak]

Also, could you please share the superpmi asmdiff numbers just to make sure that there are no surprise regressions introduced because this will get ported to .NET 6

[alexcovington]

@kunalspathak Here are the asm diffs:

Looks like the bigger regressions are caused by having to initialize both SIMD and GPR registers. Here's an example:

libraries.crossgen2.windows.x64.checked.mch

53165.asm

Baseline

xorpsxmm0,xmm0movups xmmword ptr [rsp+2B10H],xmm0movups xmmword ptr [rsp+2B18H],xmm0

Diff

xorecx,ecxxorpsxmm0,xmm0movups xmmword ptr [rsp+2B10H],xmm0mov qword ptr [rsp+2B20H],rcx

[tannergooding]

LGTM.

I'm a bit surprised this had shown up as a pipeline stall, however. Backtracking and doing a "misaligned" write is fairly common practice. Even Windows x64 memcpy does this for 16-32 byte blocks.

[kunalspathak]

I did asmdiff with this change on my local machine and seems most of the regression is because having to do copies for size < 16 or we add additional GPR moves and stop doing unaligned copies.

It seems that it just erases the previous improvements introduced in #55604 while still taking care of the regression. Below are the diffs if I revert your change in #55604 vs. the PR for benchmarks windows/x64.

I see, that's a better example of what is regressing. Let me know if there is anything else needed for this PR, thanks for all the support!

[kunalspathak]

Failures seems to be related to #59541

[kunalspathak]

Some regressions that are possibly related to this change: dotnet/perf-autofiling-issues#1603
@alexcovington - can you just double check?

[alexcovington]

@kunalspathak I will double check and update with any findings.

[kunalspathak]

Also - dotnet/perf-autofiling-issues#1591

[alexcovington]

Doesn't look like this change is related since none of the regressions appear to be generating block inits/copies.

Could you confirm why were so many files changed using jit-format? All the files are formatted as needed already.

[kunalspathak]

Probably worth adding a line of comment that further moves are not possible using YMM and so we will try XMM.

[alexcovington]

Yes, good point. I'll add a note.

[alexcovington]

@kunalspathak The large number of JIT changes happened after I ran jit-format, but I think something may have been wrong with my version of jit-format as it kept failing CI/CD. Reverted those commits and re-ran with a known good version of jit-format, hopefully that resolves the issue.

[kunalspathak]

Looks much better.

[kunalspathak]

@tannergooding - in case you want to take another look.

[kunalspathak]

Also, could you please share the superpmi asmdiff numbers just to make sure that there are no surprise regressions introduced because this will get ported to .NET 6

[alexcovington]

@kunalspathak Here are the asm diffs:

Looks like the bigger regressions are caused by having to initialize both SIMD and GPR registers. Here's an example:

libraries.crossgen2.windows.x64.checked.mch

53165.asm

Baseline

xorpsxmm0,xmm0movups xmmword ptr [rsp+2B10H],xmm0movups xmmword ptr [rsp+2B18H],xmm0

Diff

xorecx,ecxxorpsxmm0,xmm0movups xmmword ptr [rsp+2B10H],xmm0mov qword ptr [rsp+2B20H],rcx

[tannergooding]

LGTM.

I'm a bit surprised this had shown up as a pipeline stall, however. Backtracking and doing a "misaligned" write is fairly common practice. Even Windows x64 memcpy does this for 16-32 byte blocks.

[kunalspathak]

I did asmdiff with this change on my local machine and seems most of the regression is because having to do copies for size < 16 or we add additional GPR moves and stop doing unaligned copies.

It seems that it just erases the previous improvements introduced in #55604 while still taking care of the regression. Below are the diffs if I revert your change in #55604 vs. the PR for benchmarks windows/x64.

I see, that's a better example of what is regressing. Let me know if there is anything else needed for this PR, thanks for all the support!

[kunalspathak]

Failures seems to be related to #59541

[kunalspathak]

Some regressions that are possibly related to this change: dotnet/perf-autofiling-issues#1603
@alexcovington - can you just double check?

[alexcovington]

@kunalspathak I will double check and update with any findings.

[kunalspathak]

Also - dotnet/perf-autofiling-issues#1591

[alexcovington]

Doesn't look like this change is related since none of the regressions appear to be generating block inits/copies.

Could you confirm why were so many files changed using jit-format? All the files are formatted as needed already.

[kunalspathak]

Probably worth adding a line of comment that further moves are not possible using YMM and so we will try XMM.

[alexcovington]

Yes, good point. I'll add a note.

[alexcovington]

@kunalspathak The large number of JIT changes happened after I ran jit-format, but I think something may have been wrong with my version of jit-format as it kept failing CI/CD. Reverted those commits and re-ran with a known good version of jit-format, hopefully that resolves the issue.

[kunalspathak]

Looks much better.

[kunalspathak]

@tannergooding - in case you want to take another look.

[kunalspathak]

Also, could you please share the superpmi asmdiff numbers just to make sure that there are no surprise regressions introduced because this will get ported to .NET 6

[alexcovington]

@kunalspathak Here are the asm diffs:

Looks like the bigger regressions are caused by having to initialize both SIMD and GPR registers. Here's an example:

libraries.crossgen2.windows.x64.checked.mch

53165.asm

Baseline

xorpsxmm0,xmm0movups xmmword ptr [rsp+2B10H],xmm0movups xmmword ptr [rsp+2B18H],xmm0

Diff

xorecx,ecxxorpsxmm0,xmm0movups xmmword ptr [rsp+2B10H],xmm0mov qword ptr [rsp+2B20H],rcx

[tannergooding]

LGTM.

I'm a bit surprised this had shown up as a pipeline stall, however. Backtracking and doing a "misaligned" write is fairly common practice. Even Windows x64 memcpy does this for 16-32 byte blocks.

[kunalspathak]

I did asmdiff with this change on my local machine and seems most of the regression is because having to do copies for size < 16 or we add additional GPR moves and stop doing unaligned copies.

It seems that it just erases the previous improvements introduced in #55604 while still taking care of the regression. Below are the diffs if I revert your change in #55604 vs. the PR for benchmarks windows/x64.

I see, that's a better example of what is regressing. Let me know if there is anything else needed for this PR, thanks for all the support!

[kunalspathak]

Failures seems to be related to #59541

[kunalspathak]

Some regressions that are possibly related to this change: dotnet/perf-autofiling-issues#1603
@alexcovington - can you just double check?

[alexcovington]

@kunalspathak I will double check and update with any findings.

[kunalspathak]

Also - dotnet/perf-autofiling-issues#1591

[alexcovington]

Doesn't look like this change is related since none of the regressions appear to be generating block inits/copies.
