Is there some way to suppress these warnings ? 'make check-tcg'
output includes
BUILD TCG tests for aarch64-linux-user
BUILD aarch64 guest-tests with aarch64-linux-gnu-gcc
/usr/lib/gcc-cross/aarch64-linux-gnu/7/../../../../aarch64-linux-gnu/bin/ld:
warning: /tmp/cccZ8Fk7.o: unsupported GNU_PROPERTY_TYPE (5) type:
0xc0000000
/usr/lib/gcc-cross/aarch64-linux-gnu/7/../../../../aarch64-linux-gnu/bin/ld:
warning: .note.gnu.build-id section discarded, --build-id ignored.
RUN TCG tests for aarch64-linux-user
and these are going to come up in the merge-testing search
for warnings in the build logs...
thanks
