Subject: contrib/plugins/uftrace_symbols.py: ignore zero sized symbols
X-Git-Tag: v11.0.0-rc0~30^2~1
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ca144c21dd27da2d8aefa3e964ea5f98ec49cfdb;p=thirdparty%2Fqemu.git

contrib/plugins/uftrace_symbols.py: ignore zero sized symbols

When using llvm-addr2line in replacement of addr2line, it will output
zero sized symbols, which can shadow other binaries depending on where
their location is (happens with arm-trusted-firmware and its different
binaries). Thus, ignore those symbols.
