<sarcasm>
so where i can download this awesome operating system solaris for
free, oh i can not?
Shame on me i wanna use free (libre) opensource software.
I assume windows is also better... oh no source either aaah...
Windows and Solaris FTW in actual lingua...
</sarcasm>
I understand you have direct monetary benefit from Oracle or who ever
but if you do not wanna help people/ do not wanna really provide
constructive conversations please don't bother answering this email
either. Saying Solaris is better than minix / linux / *BSD and we
should use it IS NOT CONSTRUCTIVE...
I do not mind you write CDDL code for external software (which i do
not mind you do and it is good software mki... cdre... and so on)
*BUT*
Try to be constructive and write or bugfix code even if it is god
forbid written with/in GPL.
Rants about linux vs solaris way .... really you are older than that
Or just enjoy life it is free (for most parts)

Correct. A useful minimum default would be a pentium with no fdiv bug.
But as portrayed in previous mails, compiler switches don't help if you have a __asm__("pmovsomething %xmmwhatever..."); or equivalent.
This is a general problem with the quality of OSS.
The opcode is not the only problem here, another problem is the assumtion that some vendor-specific non-standard C enhancements may be used with the systems compiler.
libc is mounted to the best fit libc compile variant for performance reasons. BTW: this appeared in 1997, when 64 bit support was added to Solaris.
In glibc, all the accelerated codes live within (the one) libc.so, and ld.so resolves symbols like strchr to __strchr_sse2 / __strchr_sse42 at program startup through a mechanism that is known as ifunc. That means we do not have to provide the computationally boring parts of libc ??? such as stdio, which provides one of the largest functions according to readelf ??? more than once like it would be the case for multiple libc.so files.
Well if you believe that disk space is rare, you are right. If you believe that avoiding to fill RAM with unneeded code is more important, the Solarie method is better.
