Description Bridge Wu 2006-05-18 15:17:46 UTC 
I built cross gas for arm linux with binutils-2.16.92. The configure is below.

binutils-2.16.92/configure --target=arm-iwmmxt-linux-gnueabi --host=i686-
host_pc-linux-gnu --prefix=/usr/local/arm-iwmmxt-linux-gnueabi --disable-nls --
with-sysroot=/usr/local/arm-iwmmxt-linux-gnueabi/arm-iwmmxt-linux-gnueabi

% cat t.s
    .text
    .align 4

    .macro test label
    BNE                 \label.aaa
    B                   \label
\label.aaa:
\label:
    .endm

    test        a
    test        b

Not a bug.  Use alternate macro syntax if you want to paste formals with strings.

    .text
    .align 4

    .macro test label
    BNE                 &label&.aaa
    B                   &label&
&label&.aaa:
    nop
&label&:
    nop
    .endm

    test        a
    test        b
