Hi!


Some people pass explicit counterparts to `-march=native` for compilation and it turned out [1] that CFLAGS='-O2 -mno-sse4.2 -mno-sse4.1 -pipe' failes compilation of app/operations/layer-modes/gimpoperationnormal-sse4.c complaining that `_mm_blend_ps` cannot be inlined due to a "target specific option mismatch".

No problem if you consider this case too specific to handle; just thought you should know.

To reproduce quickly:


# tar xf gimp-2.9.8.tar.bz2

# cd gimp-2.9.8

# ./configure CFLAGS='-O2 -mno-sse4.2 -mno-sse4.1 -pipe' GEGL="$(which gegl-0.3)"

# cd app/operations/layer-modes/

# make V=1 gimpoperationnormal-sse4.o
