...e linker to behave very poorly when linking with debug symbols? http://lists.cs.uiuc.edu/pipermail/llvmdev/2007-June/009391.html -- Christopher Lamb -------------- next part -------------- An HTML attachment was scrubbed...

Seems like the memory-hog status is related to debug info, e.g. to -g. Because I later compiled the same program with RELEASE settings, e.g. $ /usr/src/llvm/dist/bin/g++ -c -pipe --emit-llvm \ -fvisibility=hidden -fvisibility-inlines-hidden \ -Wall -Wextra -Wno-sign-compare -Os \ ... lots of -Dxxxx ... \ -I/usr/share/qt3/mkspecs/default -I. -I.. \ -I../../../include/qt3

I want to share a little LLVM experiment. I tried LLVM on one of my bigger Qt 3.x based projects. I used llvm from SVN trunk (r39999) and SVN llvm-gcc-4.01 (r370) and did compile every file with /usr/src/llvm/dist/bin/g++ -c -pipe -g \ -Wall -Wextra -Wno-sign-compare \ ... lots of -Dxxxx ... \ --emit-llvm -I/usr/share/qt3/mkspecs/default \ -I. -I.. -I../../../include/qt3 -I.obj/ \
