llvm dev - Nov 2003 - [LLVMdev] llvm 1.0, g++, SuSE 9, internal compiler error

Hi aLLvm,

  compiling LLVMrelease 1.0 under SuSE 9 brings the following:

-------------------
vak at linux:~/llvm/llvm> make
make[1]: Entering directory `/home/vak/llvm/llvm/lib/Support'

Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://www.suse.de/feedback> for instructions.

here is g++ version:

Your favorite choice:

- Valery's mistake (default)
- gcc bug
- problem with SuSE distribution
- llvm sources were too sophisticated or overdeveloped
- <<I'd like to call my friend for an advice>>

?

:)

One of these two.  In theory GCC should never crash (even if the LLVM
sources had problems), and since SuSE made modifications to the compiler
before they shipped it, they implicitly took responsibility for the end
result.  You can try sending a bug report to SuSE.

That said, if you can figure out what is causing the problem, I would
definitely like to put a workaround in the LLVM code, assuming it's not
too ugly.  Compatibility with a broad range of compilers is important,
even if they are buggy.  :)

I agree.

hm, sending bug report is not my favorite hobby :)
> That said, if you can figure out what is causing the problem,
well, I know:

assert( expression && "my way to kick out gcc from SuSE 9 :)"
)

BTW, the following

(expression && "my way to kick out gcc from SuSE 9 :)")

is ok for gcc. So the problem comes from composition this argument with assert
itself.

I see. The following ugly workaround helps:

#ifdef NDEBUG
  bool b = getOption(ArgName) == Opt ;
  assert( b && "Arg not in map!");
#endif

Well, one could camouflage this :)
