>Description:
We used the following sources to build the gcc for ARM.
    gcc-3.1
    binutils-2.12.1
    newlib-1.10.0

After that, when the -march=armv5te option is given to the arm-elf-gcc, the arm-elf-gcc gives the -marmv5te option to the as(assembler).
However, the as will not accept the -marmv5te option.

We would probably think inconsistency of the options between the gcc and the as causes this problem.

The following is an execution log that shows the problem.

State-Changed-Why:
    That the assembler doesn't recognize this particular architecture variant is a problem with the assembler, not with the compiler.  Both the compiler and assembler should accept -march=armv5e and that ought to be close enough for your needs.
