Add support for riscv64gc #2323
Description
Hi,
The Rust crate jemalloc-sys currently fails to build from source on Debian (see buildd logs). The cause is that configure didn't recognize riscv64gc. tikv/jemallocator#36
jemalloc has been successfully built on an amd64 Debian chroot with qemu-user-riscv64 binaries,
- with default settings - bare
./autogen.sh, which recognizes the chroot as riscv64-unknown-linux-gnu, and - with
--host=riscv64gc-unknown-linux-gnuafter addingriscv64gctobuild-aux/config.{sub,guess}- The full command generated by jemalloc-sys build.rs is
"sh" "/root/jemallocator/target/debug/build/tikv-jemalloc-sys-7a22a3b3fd1c07ca/out/build/autogen.sh" "--disable-cxx" "--enable-doc=no" "--enable-shared=no" "--with-jemalloc-prefix=_rjem_" "--with-private-namespace=_rjem_" "--host=riscv64gc-unknown-linux-gnu" "--build=riscv64gc-unknown-linux-gnu"
- The full command generated by jemalloc-sys build.rs is
so adding riscv64gc seems trivial.
The are two "pointer reuse after realloc" errors:
