The preprocessed file
I'm trying to compile some code (in this case its a modified version of
string.cpp from libcxx) with SSE disabled (-mno-sse), but this gives me the
following error:
fatal error: error in backend: SSE register return with SSE disabled
clang-3.6: error: clang frontend command failed with exit code 70 (use -v
to see invocation)
clang version 3.6.1
Target: x86_64-unknown-linux-gnu
Thread model: posix
clang-3.6: note: diagnostic msg: PLEASE submit a bug report to
<a href="http://llvm.org/bugs/">http://llvm.org/bugs/</a> and include the crash backtrace, preprocessed source, and
associated run script.
clang-3.6: note: diagnostic msg:
********************
PLEASE ATTACH THE FOLLOWING FILES TO THE BUG REPORT:
Preprocessed source(s) and associated run script(s) are located at:
clang-3.6: note: diagnostic msg: /tmp/string-117432.cpp
clang-3.6: note: diagnostic msg: /tmp/string-117432.sh
clang-3.6: note: diagnostic msg:
********************
I'm attaching the preprocessed cpp file (which is different from the one
mentioned above since it didn't compile, complaining about using ::int8_t).
I reduced the command line to:
clang-3.6 "-cc1" "-triple" "x86_64-unknown-linux-gnu" "-emit-obj" "-target-cpu"
"x86-64" "-target-feature" "-sse" "-nobuiltininc" "-O0" "-std=c++0x" "-x" "c++"
"string.cpp"</pre>
