My issue is:

[root@localhost bin]#./llvm-profdata show --version
LLVM (http://llvm.org/):
LLVM version 15.0.4
Optimized build.
Default target: x86_64-unknown-linux-gnu

[root@localhost bin]# ./clang --version
clang version 15.0.4 (llvm-project 9176a70a8154b7ab1764e6e94f6ab58bc9f9b189)

Llvm-profdata and clang is same version，I don't know why this problem occurred？

Backtrace

1:build my code
RUSTFLAGS="-C instrument-coverage -C link-arg=--target=aarch64-unknown-linux-ohos -C linker=/home/llvm/bin/clang -C link-arg=-lpixman-1" cargo test --workspace --target=aarch64-unknown-linux-ohos --features "boot_time" --exclude mod_test --exclude ozone --no-run
2.run my binary file
export STRATOVIRT_COV=on  && export LLVM_PROFILE_FILE=/data/coverage/mst/profraw/cov-%%p-%%m.profraw
./boot_time --test-threads=1
3.put /data/coverage/mst/profraw/cov-%%p-%%m.profraw to my directory
4.grcov ../profraw -s . --binary-path ./target/aarch64-unknown-linux-ohos/debug --llvm-path /home/llvm/bin/ -t html -o ../ut-cov

My llvm-tool version is not 18.1.7,
it is 15.0.4

If I were to guess, this is exactly the problem. Rust internally bundles in LLVM, which is newer than the one you have on your system. You will need to either upgrade your system llvm to 18, or downgrade rustc to the version that bundles LLVM 15, which would be rustc-1.69.0 or earlier

Thanks for your reply.I will try it according to your method.And then,come over and reply.

@moxian
May I ask if the versions of RUST and LLVM must correspond one-to-one?
Or LLVM's version may be higher than RUST's version？

[moxian]

I don't know - I'm not an expert here.

I assume llvm can be higher version, but that's only an educated guess.

Now,I have solved this problem.
My grcov command is:
grcov ../profraw -s . --binary-path ./target/aarch64-unknown-linux-ohos/debug --llvm-path /home/llvm/bin/ -t html -o ../ut-cov
but now is:
grcov ../profraw -s . --binary-path ./target/aarch64-unknown-linux-ohos/debug -t html -o ../ut-cov
I removed the "--llvm-path" parameter,then this error has disappeared.
Thanks for your reply.@moxian
