Because for me it did not, at least not on a Mac. My workaround, which was not too painful because the new build seems to use fully-qualified path names:
touch jdk/src/share/native/java/util/zip/CRC32.c make images CONF=macosx-x86_64-normal-server-slowdebug LOG=debug ... touch jdk/src/share/native/java/util/zip/CRC32.c # copy compilation command line from above log, add -g, paste ... /usr/llvm-gcc-4.2/bin/llvm-gcc-4.2 -g ... /Users/dr2chase/work/jdk8tl-full/jdk/src/share/native/java/util/zip/CRC32.c make images CONF=macosx-x86_64-normal-server-slowdebug LOG=debug and now I am debugging. But it would be better yet to compile those files for debugging. David
