Subject: x86: Enable SSE2 by default on x86-32
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=3dff8af3033a9e81d7966c5749fd361ce421467a;p=libx264

x86: Enable SSE2 by default on x86-32

It makes more sense to tune the defaults to benefit the vast majority of users.

Anyone still using a Pentium III for video encoding is of course free to
explicitly set different flags when compiling.
