in cmake)
For me it is not valid, it doesn't do what you think.

You are right. There is no RelWithDebInfo option. But it could be a nice future
addition ;-)
For the parameter you can drop -m32 (only useful on 64 bits machine
anyway) no
impact. I'm not sure i686 is important but is there any sse2 cpu that doesn't
support i686 instruction set? PCSX2 requires a powerful PC it won't run on 10
years old PC anyway. Checked i686 is 1995 so 17 years old! It is older than the
PS2 ;)
These are the flags actually used by Fedora to build for i686:
CFLAGS='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions
-fstack-protector --param=ssp-buffer-size=4 -m32 -march=i686 -mtune=atom
-fasynchronous-unwind-tables'
They are mandatory. This means you have to build Fedora packages with these
flags. As you can see they already include "-m32 -march=i686".
"--march=i686"
implies only Pentium Pro and does not imply MMX or anything newer:
https://fedoraproject.org/wiki/Features/F12X86Support
Not all i686 processors, like the AMD Geode LX (and this is currently shipped),
support SSE or SSE2. And this is a problem for us.
As upstream I will try to post somewhere a tar gz.
Thanks!
