+Subject: [PATCH] Fix build on i686
+
+Presumably this only matters for i686 because amd64 implies sse2, but:

+BUILDSTDERR:  #define OUT_VERTEX(x,y) vertex_emit_2s(sna, x,y) /* XXX assert(!too_large(x, y)); */
+BUILDSTDERR:                          ^~~~~~~~~~~~~~~~~~~~~~~~
+BUILDSTDERR: gen4_vertex.c:360:2: note: in expansion of macro 'OUT_VERTEX'
+BUILDSTDERR:   OUT_VERTEX(dstX, dstY);
+BUILDSTDERR:   ^~~~~~~~~~
+
+The bug here appears to be that emit_vertex() is declared 'sse2' but
+vertex_emit_2s is merely always_inline. gcc8 decides that since you said
+always_inline you need to have explicitly cloned it for every
+permutation of targets. Merely saying inline seems to do the job of
+cloning vertex_emit_2s as much as necessary.
+
+So to reiterate: if you say always-inline, it won't, but if you just say
+maybe inline, it will. Thanks gcc, that's helpful.
