• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description jadd 2010-09-18 18:24:00 UTC]

I can not compile with the option msseregparm, otherwise I have no problem. I can not find anywhere if msseregparm is dangerous option and how many packages it with this option could not compile.

Reproducible: Always

Steps to Reproduce:
1. emerge -vDe world
2.
3.

man gcc.
    -msseregparm
           Use SSE register passing conventions for float and double arguments
           and return values.  You can control this behavior for a specific
           function by using the function attribute -msseregparm.

           Warning: if you use this switch then you must build all modules
           with the same value, including any libraries.  This includes the
           system libraries and startup modules.

So, why is it you are trying to use this CFLAG and what do you think it will give you?

Also, please explain what the *PROBLEM* is. From looking at your bug report, I cannot see anything obviously wrong.

Noted that I think this specific problem is outside the realm of what we should be supporting, and if it is indeed a problem in perl not compiling with that flag, we're probably just going to mask that flag, and punt it upstream.

I agree.
