When building natively on RISC-V, linking the bootstrap clang-tblgen fails with: ld: error: undefined symbol: llvm::EnableABIBreakingChecks >>> referenced by PrettyStackTrace.cpp >>> PrettyStackTrace.o:(.sdata+0x0) in archive /usr/obj/usr/src/freebsd-src/riscv.riscv64/tmp/obj-tools/lib/clang/libllvmminimal/libllvmminimal.a >>> referenced by Signals.cpp >>> Signals.o:(.sdata+0x8) in archive /usr/obj/usr/src/freebsd-src/riscv.riscv64/tmp/obj-tools/lib/clang/libllvmminimal/libllvmminimal.a >>> referenced by Timer.cpp >>> Timer.o:(.sdata+0x28) in archive /usr/obj/usr/src/freebsd-src/riscv.riscv64/tmp/obj-tools/lib/clang/libllvmminimal/libllvmminimal.a This is likely due to Error.h's inclusion of abi-breaking.h. It's unclear why this only affects RISC-V, but perhaps relates to its more eager use of .sdata due to the ABI's support for linker relaxations. Regardless, this is theoretically an issue for all architectures.
