Fwd: [PATCH, libgcc]: Avoid "left shift count >= width of type" warnings in soft-fp code

[Uros Bizjak <ubizjak at gmail dot com>]

[Forwarded from gcc-patches@... mailing list, where the patch was
bootstrapped and regression tested. Please note that I have no means
of properly testing the patch as required by glibc rules.]

Hello!

Attached patch removes "left shift count >= width of type" warnings in
soft-fp code. The patch implements the same approach - checking of
rsize against _FP_W_TYPE_SIZE - as is implemented in corresponding
FP_FRAC_DISASSEMBLE_{2,4} macros a couple of lines below.

This patch removes all remaining soft-fp warnings from the build.

    * soft-fp/op-2.h (_FP_FRAC_ASSEMBLE_2): Check rsize against
    _FP_W_TYPE_SIZE to avoid "left shift count >= width of type" warning.
    * soft-fp/op-4.h (_FP_FRAC_ASSEMBLE_4): Ditto.

Bootstrapped and regression tested on x86_64-pc-linux-gnu {,-m32}.

OK for mainline?

Uros.
