Mar 31 2022, 12:59 AM · Restricted Project, Restricted Project
qiucf added a comment to D121992: [Clang] [Driver] Add option to set alternative toolchain path.

To add more why I think the current semantics may need more discussion before we quickly commit to such a driver option:

  • interaction with --dyld-prefix: --sysroot does not affect the fallback --dyld-prefix. It seems even less appropriate for --overlay-platform-toolchain to affect the fallback --dyld-prefix.

If you intend to overlay ld.so, you'll necessarily overlay libc, then --sysroot seems just unneeded at all.

  • interaction with --gcc-toolchain: I am a bit unclear we still want the tricky GCC installation detection after --overlay-platform-toolchain is specified. Do you propose that both will add include and library search paths?
  • -B: in gcc, when -B prefix specifies a directory, GCC adds $prefix/include to the include search directory. Clang does not do this right now. I think adding it may be an alternative approach to introducing the new option.

The currently picked rules may be suitable for https://github.com/advancetoolchain/advance-toolchain, but could be arbitrary for many other use cases.
Have you considered putting some options into a configuration file and using --config?

I understand that you probably have some short-term goal to make somethings done, but as I mentioned, there might be some process issue here.
This significant new feature very quickly landed without other driver folks possibly had a chance to chime in.
(FWIW I decided to subscribe all clang/lib/Driver patches since I care about this area.)
I very rarely do this but I think it is probably cleaner to revert this patch and discuss it more carefully. I am happy to help you achieve your goal. It's possible that we may still need a driver option.

qiucf added a comment to D116015: [PowerPC] Add generic fnmsub intrinsic.

hiding the semantics from the optimizer is sometimes a good thing and sometimes a bad thing).

Agree. Imagining a case when the neg and fma (from fnmsub) can both be CSE-ed with another neg and fma, so we can totally eliminate the fnmsub. But after we convert it to an intrinsic, we may lose the opportunity to CSE the fnmsub.

Here's a pretty simple case: vector float foo(vector float a, vector float b, vector float c, vector float d) { return __builtin_vsx_xvnmsubasp(c, d, a*b); }
It current produces xvnegsp+xvmulsp+xvnmaddasp, after this patch it produces xvmulsp+xvnmsubasp. In some complicated cases, we can see much more unexpected instructions generated.

This is narrowed down from a real-world case. After CSE some part of the fnmsub, it is hard to optimize it back to a single hardware fnmsub instruction as normally we check the use number of a register and if the user number is not 1, we may exit the combine.

Is it possible to get some perf data for some float workloads with this patch? @qiucf

qiucf added a comment to D112906: [PowerPC] Emit warning for ieeelongdouble on older GNU toolchain.

Is that because clang lacks something required by this feature? (for example. clang-12 doesn't have __ibm128 and many builtins) If so, clang-14 should have these fixed.

When I implemented the libstdc++ changes Clang didn't have any of your work yet. Now that everything seems to be present, and __LONG_DOUBLE_IEEE128__ and __LONG_DOUBLE_IBM128__ are defined as appropriate, I think I can enable it for clang. I'll look into that tomorrow.

qiucf added a comment to D116015: [PowerPC] Add generic fnmsub intrinsic.

Converting more generic code to target-specific intrinsics is sometimes necessary to ensure the generic IR doesn't get transformed in a way that is disadvantageous. I believe that the description of this review claims that to be the case for these negated FMA's. The obvious disadvantage of producing target-specific intrinsics is that the optimizer knows nothing about them so no advantageous transformations can happen either (i.e. hiding the semantics from the optimizer is sometimes a good thing and sometimes a bad thing).

The description of this patch includes no test case that shows the optimizer performing an undesirable transformation. So the motivation for making the front end produce more opaque code is not at all clear.

qiucf added a comment to D114800: [PowerPC] Replace MFVSRLD with MFVSRD when the vector is symmetrical.

Can we fix this at the place where MFVSRLD is generated? (in DAG-ISEL?)

I see what you mean. This can be done in DAG-ISEL.
However, there are a couple of reasons why I chose to do this here.

  1. I think it is easier to do here and the code is simpler to understand. We are looking to replace MFVSRLD so we just look for that instruction and then replace it. In DAG ISEL we would have to first figure out which extract element node eventually gets turned into this instruction and then see if it can be replaced.
  2. There are situations where the choice of preceding instructions matters to whether or not we can use the other doubleword. Again, it would be a situation where we would have to figure out what a node is turned into before deciding if the doubleword is symmetrical.
