Compilation fails with optimization set higher than -O1

[marcinblazejowski]

Hi,

this is a report produced by icx (Debian testing/unstable, oneAPI installed from DEB-s):

CFLAGS="-march=native -mtune=native -O3"
CXXLAGS="-march=native -mtune=native -O3"

NOTE: setting to "-O1" works well!!

Hi,

Thank you for posting in Intel Communities.

We were able to reproduce your issue with -O3 optimization flag.

Could you please provide the following details so that we can investigate the issue more from our end?

1. Have you tried with -O2 optimization flag. If you have tried let us know the results. 

2. oneAPI version you are using.

3. Clang version you are using.

4. Hardware you are using.

5. Please isolate the code where you are observing the error and provide the small reproducible code and steps you have followed.

Thanks and Regards,

Pendyala Sesha Srinivas

Hi,

1. Yes - with the same results as with -O3 => I would say that compilation not fail if I have "-Ox && x <=1".

2. I would say 2022.2.1 (current DEB-s from you repos).

3.  icx - v:

4. I'm not sure, but I think it is 15.x.x taken by you from git repo on February, 2022.

5. Dell Inspiron 17 7773 2-in-1 (service TAG: JK2KTJ2). I short: i7-8550U CPU @ 1.80GHz

6. Ohh, that would certainly not be easy. Don't get me wrong, it does not mean I don't want to do this. General remark: we're talking about gretl project (https://sourceforge.net/projects/gretl/), so isolating the very small piece of code could be tricky a little. However, you can play with the whole sources, don't you? But look at project activity: last night Alling Cottrell applied a patch which is 'temporary hack for icx and rqbr.c' [https://sourceforge.net/p/gretl/git/ci/51d5cda091025743a04767b687433ae10843588e/].

Hi,

We are unable to reproduce the issue while trying with -O1 optimization flag.

Could please let us know at which step of the code you are facing this issue?

Have you tried the temporary hack for icx? If works, please let us know the results.

Thanks and Regards,

Pendyala Sesha Srinivas

[marcinblazejowski]

Hi,

good for you!!! I would say then that your results are inline with mine, since I wrote:

1. in the first post: 'NOTE: setting to "-O1" works well!!'.
2. in the second post: 'I would say that compilation not fail if I have "-Ox && x <=1"'.

So again: compilation fails if I have -O2 or -O3 (more aggressive optimization). What might be important: vanilla clang-15 (15.0.6 from Debian repos) compiles the code regardless the optimization settings.

Cheers,
Marcin

Hi,

We were able to reproduce your issue. We have informed the development team about it.

We will get back to you soon.

Thanks and Regards,

[SeshaP_Intel · Accepted solution]

Hi,

Thank you for your patience. The issue raised by you has been fixed in the 2023.1 version which will be released in the coming months. If the issue still persists with the new release, then you can start a new discussion for the community to investigate.

Thanks and Regards,

Hi,

good to know, thanks!!!

Hi Pendyala ,

We (TACC users) do see the same error with the new release 24.1. I am submitting another ticket for it.

[marcinblazejowski]

Aruhela,

I cannot confirm this: in my case compilation with 24.1 works fine.
