Hi Mike, If you're doing this for Clang's benefit, I think the best thing to do is to compile LLVM PIC (the default) and then build the clang front- end pieces with -mdynamic-no-pic. Does

As part of our automated testing, I'm running make check-all to watch for failures. One of my builds uses the --enable-optimized option to configure. When I build the latest trunk, I'm now seeing 18 failing tests: Clang :: Preprocessor/macro_paste_c_block_comment.c LLVM :: CodeGen/ARM/2011-05-04-MultipleLandingPadSuccs.ll LLVM :: CodeGen/ARM/2011-11-14-EarlyClobber.ll LLVM

I recommend you don't parse version strings. In fact I switch the check to use AC_COMPILE precisely for the reason that gcc --version is totally unreliable and vendor specific. For example, what's the regular expression that tells you what the GCC version is: i686-apple-darwin9-gcc-4.0.1 (GCC) 4.0.1 (Apple Inc. build 5470) (Aspen 5470.3) Per the rest of this thread, you can't

...right (the actual binaries are in the 'bin' subdirectory). I don't think --enable-checking should be necessary, I had llvm ./configure'd with --enable-optimized (I hope that's the same as specifying ENABLE_OPTIMIZED=1 during the 'make' run for LLVM proper).

Does anyone have any ideas on what the problem is? Any help would be greatly appreciated.

hi, I've been trying to avoid spamming the list but I don't know where else to bang my head using the latest trunk and 2.1, I always get this: llvm[2]: Linking Release executable tblgen (without symbols) /targets/SDK_BETA_ARMEL/mnt/shared/repos/svn/llvm/llvm-project/llvm/trunk/utils/TableGen/Release/InstrInfoEmitter.o:(.rodata._ZTVN4llvm4UserE[vtable for llvm::User]+0x10): undefined

...is is gcc crashing. Can you try upgrade / downgrade to a different version of gcc? Also, you can do make VERBOSE=1 to see how it is crashing. You can then produce a preprocessed file and submit the report to the gcc mailing list. For now, I would suggest you go to Makefile.rules and change OPTIMIZE_OPTION from -O3 to -O2. If you are lucky that will allow it to get past this crash.
