Subject: [PATCH 1/3] elf: Replace .tls_common with .tbss definition
Date: Sun, 25 Jul 2021 20:58:00 -0700 [thread overview]
Message-ID: <20210726035802.275992-2-maskray@google.com> (raw)
In-Reply-To: <20210726035802.275992-1-maskray@google.com>
.tls_common is obsoleted, not supported by clang -fintegrated-as or ld.lld.
Just change it to .tbss for portability.
