Hello,
I am trying to do some data-flow analysis for a
project for which I am adding a new pass to the
optimization code.
I have modified the Makefiles to properly compile the
code, and it is able to create the object files
correctly, but fails at this point
ranlib libbackend.a
gcc -g -DENABLE_CHECKING -DENABLE_ASSERT_CHECKING
-DIN_GCC -W -Wall -Wwrite-
strings -Wstrict-prototypes -Wmissing-prototypes
-Wold-style-definition -DHAV

libbackend.a(tree-optimize.o): In function
`init_tree_optimization_passes':
/cygdrive/c/gcc-4.0.2/gcc/tree-optimize.c:337:
undefined reference to `_pass_dfa
Can anyone tell me what the problem might be and how
to fix it?
Thanks
