__asan_handle_no_return undefined in lib for i386

[ramosian-glider]

Originally reported on Google Code with ID 42

What steps will reproduce the problem?
1. Build latest Asan (r150801)
2. Try to build a i386 binary (my host is x86_64) that needs to call __asan_handle_no_return

What is the expected output? What do you see instead?

No output, I expect a working binary

› clang -g -faddress-sanitizer -fno-omit-frame-pointer -m32 -march=pentiumpro -pipe
-Dlinux -Di386 -ffunction-sections -fdata-sections -Wno-return-type no_return.c
/tmp/no_return-bDQzje.o: In function `functionA':
/tmp/no_return.c:7: undefined reference to `__asan_handle_no_return'
clang: error: linker command failed with exit code 1 (use -v to see invocation)

If I remove the i386 flags it works.

What version of the product are you using? On what operating system?

Everything works for me with r150810:


$ build/Release+Asserts/bin/clang -g -faddress-sanitizer -fno-omit-frame-pointer -m32
-march=pentiumpro -pipe -Dlinux -Di386 -ffunction-sections -fdata-sections  t.c -o
t
$ ./t
It works.

$ nm build/Release+Asserts/lib/clang/3.1/lib/linux/libclang_rt.asan-x86_64.a  | grep
no_return
                 U __asan_handle_no_return
00000000000009a0 T __asan_handle_no_return

$ nm build/Release+Asserts/lib/clang/3.1/lib/linux/libclang_rt.asan-i386.a  | grep
no_return
000013c0 T __asan_handle_no_return
         U __asan_handle_no_return

I tried again works for me too with r150828.

I probably messed up somewhere in the build/install sorry for the trouble.

Just fyi, I also ran into this problem (the no_return symbol missing), and it turned
out that my compiler-rt rev was not in sync with my llvm/clang revs (higher llvm/clang
version). So if anyone else runs into this problem, make sure all three repos are on
the same version.

Ok, hope this can be closed now.
