The rewrite in C is good since it's a lot faster but why did the output format change? I am using it on our virtualized servers to automatically create a make include file to set all the CPU flags. The new format isn't compatible to the make.conf format anymore. old: CPU_FLAGS_X86="mmx mmxext popcnt sse sse2 sse3 sse4_1 sse4_2 ssse3" new: CPU_FLAGS_X86: mmx mmxext popcnt sse sse2 sse3 sse4_1 sse4_2 ssse3 Would it be possible to at least include the old format via a command line parameter?

The new format is easier to output and more portable. It's supported in Portage's package.use and Paludis' options.conf/use.conf. @Prefix, please proceed with testing/keywording :). Feel free to try non-Linux systems as well as those are supported now.

Before I could use "cpuinfo2cpuflags-x86 >> /etc/portage/make.conf" which doesn't work anymore. I used to create a custom config which was included in my make.conf. And on every server restart it got repopulated in case the VMs were moved around.

And on > every server restart it got repopulated in case the VMs were moved around. echo "*/* $(cpuinfo2cpuflags-x86)" >> /etc/portage/package.use Though I never thought about using the tool in scripts. Sorry. appears to compile and run on x64-solaris (gcc 4.7) CPU_FLAGS_X86: mmx mmxext sse sse2 sse3 ssse3 and x64-macos (using Clang 3.5) CPU_FLAGS_X86: aes avx avx2 fma3 mmx mmxext popcnt sse sse2 sse3 sse4_1 sse4_2 ssse3 If possible, please try comparing with results given by platform-local CPU feature detection utilities or such. I think the MacOS way is: /usr/sbin/sysctl machdep.cpu.features machdep.cpu.leaf7_features machdep.cpu.extfeatures |
