Hi Sheng,<div><br class="webkit-block-placeholder"></div><div>If you're still seeing this, try getting a .ll file from the code and then running bugpoint on it. If you're unable to get the .ll file (it still crashes when using -S -emit-llvm), then try running "delta" on the pre-processed file. See this webpage for details on how to run delta:</div><div><br class="webkit-block-placeholder"></div><div><span class="Apple-tab-span" style="white-space:pre"> </span><a href="http://gcc.gnu.org/wiki/A_guide_to_testcase_reduction">http://gcc.gnu.org/wiki/A_guide_to_testcase_reduction</a></div><div><br class="webkit-block-placeholder"></div><div>This will at least give us a starting point. :-)</div><div><br></div><div>-bw</div><div><br></div><div><div><div>On Mar 4, 2008, at 1:24 AM, Zhou Sheng wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite">Current llvm-gcc 4.2 building failed on X86-64, here is the dump information:<br><br>xgcc -B/home/zsth/projects/llvm.org/build/cfe4.2obj/./prev-gcc/ -B/home/zsth/projects/llvm.org/install/x86_64-unknown-linux-gnu/bin/ -I../../../cfe4.2/libcpp -I. -I../../../cfe4.2/libcpp/../include -I../../../cfe4.2/libcpp/include -DENABLE_LLVM -g -O2 -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -Wmissing-format-attribute -pedantic -Wno-long-long -I../../../cfe4.2/libcpp -I. -I../../../cfe4.2/libcpp/../include -I../../../cfe4.2/libcpp/include -DENABLE_LLVM -c -o directives.o -MT directives.o -MMD -MP -MF .deps/directives.Po ../../../cfe4.2/libcpp/directives.c<br> ../../../cfe4.2/libcpp/directives.c: In function 'do_pragma':<br>../../../cfe4.2/libcpp/directives.c:1376: internal compiler error: Segmentation fault<br>Please submit a full bug report,<br>with preprocessed source if appropriate.<br> See <URL:<a href="http://developer.apple.com/bugreporter">http://developer.apple.com/bugreporter</a>> for instructions<br><br>Any ideas?<br><br>My gcc version:<br>gcc -v<br>Using built-in specs.<br>Target: x86_64-redhat-linux<br> Configured with: ../gcc-4.0.4/configure --prefix=/home/toolman/gcc4.0.4-x86_64 --enable-languages=c,c++ --host=x86_64-redhat-linux<br>Thread model: posix<br>gcc version 4.0.4<br><br><br><br>Thanks,<br>Sheng.<br><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">_______________________________________________</div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">LLVM Developers mailing list</div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><a href="mailto:LLVMdev@cs.uiuc.edu">LLVMdev@cs.uiuc.edu</a> <span class="Apple-converted-space"> </span><a href="http://llvm.cs.uiuc.edu">http://llvm.cs.uiuc.edu</a></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><a href="http://lists.cs.uiuc.edu/mailman/listinfo/llvmdev">http://lists.cs.uiuc.edu/mailman/listinfo/llvmdev</a></div> </blockquote></div><br></div></body></html>
