It makes the program incorrect.

Hi again,
i have been studing gcc docs to undestand SSA and steps to take to get
SSA form. In one GCC online document:
http://gcc.gnu.org/projects/tree-ssa/#ssa, the steps to translate to
SSA form are listed. Here, i copy and paste the mentioned text:

Conversion to SSA form is a three step

I just say that crlibm is not it. There are libms which would impose

hi , when I try to compile the busybox 1.1.3 using buildroot in cygwin.
an internal compiler error happens.
Could any one give a help on this?

Are you emitting CLI directly from GIMPLE?
Yes, we emit gimple right before GIMPLE is transformed into RTL so our code
doesn't go through the RTL-only optimizations
It may help to look at
store_bit_field and extract_bit_field so see how this sort of thing is
handled
