 Posted: Fri Aug 11, 2017 11:31 am Post subject: Wiki page about GCC optimization looks outdated |
 |
|
I read the wiki page about GCC optimization, and I have noticed that it suggests to install | Code: | | app-portage/cpuid2cpuflags |
, Additionally, to automatically fetch the CPU_FLAGS_X86, it suggests to run it executing ; however, that command does not work.
I currently have the latest version of cpuid2cpuflags, as you can see in the following box:
| Code: |
gentoorocks ~ # emerge -s cpuid2cpuflags
[ Results for search key : cpuid2cpuflags ]
Searching...
* app-portage/cpuid2cpuflags
Latest version available: 1
Latest version installed: 1
Size of files: 2 KiB
Homepage: https://github.com/mgorny/cpuid2cpuflags
Description: Script to guess CPU_FLAGS_X86 flags from /proc/cpuinfo
License: BSD-2
[ Applications found : 1 ]
|
In order to run it, however, it is necessary to type the following:
| Code: |
gentoorocks ~ # cpuinfo2cpuflags-x86
CPU_FLAGS_X86="aes avx mmx mmxext pclmul popcnt sse sse2 sse3 sse4_1 sse4_2 ssse3"
|
I think the wiki should be updated. |

Moved from Installing Gentoo to Gentoo Chat. Not exactly a support question.
