clang compiler produces optimized code which calls memset which is missing when kernel.trampoline is linked. inflate-tramp.o: In function `inflate_dynamic': /Volumes/data/src/freebsd/sys/kern/inflate.c:(.text+0x538): undefined reference to `memset' inflate-tramp.o: In function `huft_build': /Volumes/data/src/freebsd/sys/kern/inflate.c:(.text+0xb1c): undefined reference to `memset' This can be avoided by passing -ffreestanding (diff attached).
Author: cognet Date: Wed Jun 15 19:15:50 2011 New Revision: 223116 URL: http://svn.freebsd.org/changeset/base/223116 Log: Add -ffreestanding to the command line, so taht inflate.c compiles and link properly with llvm.
