Basic questions like this are really more appropriate for the gcc-help
list.  The gcc list is supposed to be for questions about gcc
development.  Not beginner questions like this.

You should look at
    http://gcc.gnu.org/bugs.html
which has info on how to properly report a bug.  You left out some
important info here, primarily the testcase test.c, but also the gcc
version.

You should also get some MIPS ISA manuals and study them.  There is no
(integer) madd
instruction in the MIPS4 ISA.  Maybe you meant madd.d or madd.s?
