[PATCH][AArch64] request to push AArch64 patches to release 3.4 branch

Thu Dec 5 13:24:28 PST 2013

Hello Bill,

My patches have been merged to mainline, can you please merge them to branch
3.4 along with Jiangning's changes listed below?

[clang] r196535 - Implemented vget/vset_lane_f16 intrinsics

[llvm] r196533 - Implemented vget/vset_lane_f16 intrinsics

Thanks,

Ana.

Hi Bill,

We have more commitments in the past several days. Could you please help to
merge them all together to branch 3.4?

r196189 r

196190 

Add missing intrinsics like vmlsl_high_n_xxx

r196191 r

196192

Add missing SISD misc integer intrinsics

r

196198

r196199 

Add missing SISD pair intrinsics

r

196208

r196209 

Add missing ACLE intrinsics mapping to general arithmetic operation from VFP
instructions

r

196211

r196211 

Add missing floating point convert, round and misc intrinsics

r

196359 r196360 

Add missing compare intrinsics

r

196361 r196362 

Add missing instrinsics vceqz_f64

r

196456 

                     *** 

Add missing register cost calculation for big value types like v4i64 and
v8i64

1) The last one marked with "***" is critical, and would break most of -O1
and -O2 code containing vector load store, so this one should go into branch
3.4 with high priority.

2) All the others covers all of missing intrinsic functions for AArch64
Neon. Hopefully they can go into branch 3.4 as well.

After merging those commitments, for AArch64 Neon work, the status is,

1) MClayer can pass MCHammer test.

2) For intrinsics implementation defined in ACLE 2.0, we will be having two
commitments only. A) Ana's patch for vset/vget_lane_f16, which is being
under code review in mail list. B) The patch for poly128 and related things.
Kevin will probably send out the patch by tomorrow.

Hopefully If possible, 2.A) and 2.B) can both go into branch 3.4. And that
way we would be able to claim we have a complete AArch64 Neon feature in 3.4
release.

Thanks,

-Jiangning

Hi Bill and Tim,

Thanks for merging all the patches to branch 3.4. We will have a couple more
coming this week to complete Neon intrinsics implementation.

Here are the patches from me that need to go to 3.4 branch:

Clang:

r196206 Fixed vcopy_laneq_f64 intrinsic implementation

196153: Implemented vcopy_lane patterns using scalar DUP instruction

LLVM:

196151 Implemented vcopy_lane patterns using scalar DUP instruction

Thank you,

Ana.

Hi Jiangning,

Thanks for the list! I added them into the 3.4 release branch. Please let me
know if there are any I missed.

Hi Bill,

Now we have a couple new patches for 3.4 release, so could you please help
to merge them into the branch?

r195068

Clean up predefined macros for AArch64 to follow ACLE 2.0.

r195069 r195071

All crypto intrinsics should be unavailable when crypto feature is not
enabled        

r195073 r195074

Implement SISD intrinsics for vget_high and vget_low

r195713

Implement 128 bit register copy with NEON.

r195903

*** Fix the problem that AArch64 Post-index LD4 lane is decoded incorrectly

r195844 r195843 r195905 r195932

*** Fix the failure exposed by checking constant integer argument range

r195937

Add missing intrinsic vcombine_f64

r195936

*** Fix An assertion failure caused by disassembling AArch64 SHLL
instruction

r195938 r195939 r195940

Add missing intrinsic bsl_f64

r195941 r195942

*** The pattern match should check the range of the immediate

r195943

*** Some ACLE intrinsics in arm_neon.h return float32 instead of float64.

The ones marked with "***" are critical ones because they are bug fixes
either for MCLayer or ACLE, and they should go into branch with the high
priority.

Ideally we want all of them go into branch, because they are combined all
together as a big feature for AArch64 NEON implementation.

Thanks,

Thank you Bill,

We have a fix from Hao that should also go into branch 3.4 (it's a fix of
encoding error for ld/st instruction): r195591

Can you merge it too, please.

Thanks,
Ana.
