Sorry, I will report druntime related into upstream in future. this one is reported.
this patch fix the riscv64-unknown-linux-musl druntime

but I get a warning like this:
ldc2 -mtriple=riscv64-unknown-linux-musl --target-abi=lp64d -mattr=+zba,+zbb,+zbc,+zbs test.d
Hard-float 'd' ABI can't be used for a target that doesn't support the D instruction set extension (ignoring target-abi)
Hard-float 'd' ABI can't be used for a target that doesn't support the D instruction set extension (ignoring target-abi)
after add Hard-float 'd' ABI, then I can build for https://github.com/libriscv/libriscv with ldc2. (it can be used for game plugin, hard-float is required for good performance)
ldc2 -mtriple=riscv64-unknown-linux-musl --target-abi=lp64d -mattr=+zba,+zbb,+zbc,+zbs --float-abi=hard test.d with lto link there will be error:
cannot link object files with different floating-point ABI from /risc64/bin/../sysroot/lib/crt1.o
with -mattr=+d skip this warning:
Hard-float 'd' ABI can't be used for a target that doesn't support the D instruction set extension (ignoring target-abi)
Hard-float 'd' ABI can't be used for a target that doesn't support the D instruction set extension (ignoring target-abi)
still get lto link error.
the clang sysroot/lib/crt1.o:

with -mattr=+m,+a,+f,+d,+zicsr,+zifencei,+zmmul,+zaamo,+zalrsc,+zba,+zbb,+zbc,+zbs get same Tag_RISCV_arch like sysroot/lib/crt1.o but still get error:

I think you want -mabi=lp64d, not -target-abi - the latter is a (recent) LLVM option which we forgot to hide (I've only seen this recently, along with a bunch of other new LLVM options - will be fixed when merging the LLVM-20 PR).
It still same error.
I report wrong 'ldc2 lto object arch' (it is read from without lto object), the object with lto create by ldc2 is LLVM bitcode file. and the llvm-bcanalyzer result is

in the lto step, when it pass to clang , some how the object arch is not follow the arch set by ldc2.
the clang get -Wl,-plugin-opt=mcpu=generic-rv64 -mabi=lp64d -march=rv64g
without lto it already work well.
