[cfe-dev] Issue #2 with clang-analyzer on RTEMS

[Joel Sherrill]

  Hi,

Issue #2 I encountered...

The second problem is that native .h files are being picked up in a
strictly cross (x86-linux -> sparc-rtems) build.  I used the following
command to run the analysis.

scan-build -o ${OUTPUTDIR} --experimental-checks \
    --use-cc ${RTEMS_TARGET}-gcc \
    --use-c++ ${RTEMS_TARGET}-g++ \
    make

where RTEMS_TARGET was sparc-rtems4.11

Thanks.
