What are the current limitations of using -O4 in llvm-gcc-4.2? As a first test, I compiled the molscript program first as -O3 and it works fine. However if i try to compile the same code as -O4, the build fails with... ar -cru clib.a args.o str_utils.o dynstring.o err.o indent.o vector3.o matrix3.o quaternion.o body3d.o extent3d.o io_utils.o colour.o key_value.o named_data.o double_hash.o hermite_cur...

I am running into some problems when trying to use llvm-ld to link object files, created by llvm-gcc-4.2 at -O4, with the stock libraries available on powerpc-apple-darwin9. In particular, I am finding that the link command... llvm-ld -O4 -native -o molscript molscript.tab.o global.o lex.o col.o select.o state.o graphics.o segment.o coord.o xform.o postscript.o raster3d.o vrml.o regex.o opengl.o image.o eps_img.o sgi_img.o jpeg_img.o png_img.o clib/clib.a /sw/lib/libfreeglut.3.8.0.dylib /usr/X11R6/lib/libGLU.1.3.dylib /usr/X11R6/lib/libGL.1.2.dylib /Sys...

Using -O4 requires support from the system linker, because the files written out are LLVM bitcode files rather than object files. --Owen On Dec 29, 2007, at 11:43 AM, Jack Howarth wrote: > What are the current limitations of using -O4 in > llvm-gcc-4.2?
