- Subject: Disable SSE3 features in glibc
Hi,
I want to prevent glibc from using its SSE3 routines such as :
__strncpy_ssse3 even though the machine supports those features. Is
there anyway to do it?
Right now I am thinking that I need to recompile glibc. However, I am
not sure which configuration flag should I use.
I am on a 64-bit machine, but there is only one - - host option
(x86_64) unlike the 32-bit host.
I found the compilation guide for glibc:
http://tldp.org/HOWTO/html_single/Glibc-Install-HOWTO/
However, it seems a bit complicated. So I am thinking of using
Fedora's glibc source rpm. Hopefully, I can compile and install glibc
with a special setup like the method in the link.
Please suggest
