@ -6,6 +6,13 @@ llvm-toolchain-10 (1:10.0.0-3) unstable; urgency=medium
* Cherry-pick upstream patch D74453 to fix atomic compare-and-swap on
riscv64.
[ William Grant ]
* debian/patches/riscv64-multilib-empty.patch: Adjust riscv64 GCC detector
to also check for existence of crtbegin.o in the default multilib dir,
like most other ports. Fixes FTBFS on riscv64, since on Ubuntu
/usr/lib/gcc/riscv64-linux-gnu/10 exists but is empty (gcc-10-base is
installed, but libgcc-10-dev is not).
