Quoting Jan Hubicka [EMAIL PROTECTED]:
If you make FPCTR/MXCSR real registers, you will need to add use to all
the arithmetic and move pattern that would consume quite some memory and
confuse optimizers. I think you can get better around simply using volatile
unspecs inserted by LCM pass
Hello!
Well you really want both the fpcr and the mxcsr registers, since the fpcr
only controls the x87 and the mxcsr controls the xmm registers. Note, in
adding these registers, you are going to have to go through all of the
floating
point patterns to add (use:HI FPCR_REG) and (use:SI

Hello!
It looks that i387 control word register definition is missing from register
definitions for i386 processor. Inside i386.h, we have:
#define FIXED_REGISTERS \
/*ax,dx,cx,bx,si
