    Subjectread-write constraint warnings
    Date
    Hi all,

    I see this has been raised before, but could not find a closure thread:

    e.g.
    include/asm/bitops.h:79: warning: read-write constraint does not allow a
    register

    Since moving 2.6.15.7 --> 2.6.16.4 I get truck loads of these warnings.

    nick@linuxamd:linux$ gcc -v
    Reading specs from /usr/lib/gcc/i486-slackware-linux/3.4.0/specs
    Configured
    with: ../gcc-3.4.0/configure --prefix=/usr --enable-shared --enable-threads=posix --enable-__cxa_atexit --disable-checking --with-gnu-ld --verbose --target=i486-slackware-linux --host=i486-slackware-linux
    Thread model: posix
    gcc version 3.4.0

    nick@linuxamd:linux$ ld -v
    GNU ld version 2.15.90.0.3 20040415

    There is no problem as kernels built with these warnings are fine, so a GCC
    issue I presume?

    Nick
