Thought I'd toss this out there for folks interested (or that might be able to help me).
John Rose has been maintaining (or at least has pointers to) a Hotspot disassembler plugin here: http://wikis.sun.com/display/HotSpotInternals/PrintAssembly I've used it in the past, and although it's pretty raw it's the only way to see the actual final assembly Hotspot is generating. You need to turn on a few other flags to interlace enough information to know what's what. If you're not comfortable with raw assembly, stick to +PrintOptoAssembly (only in fastdebug/debug builds...emits pseudo-assembly and some fictional instructions that are eventually composited into appropriate sequences for the host platform). Now that you know about that, here's my build problem. Seems to be a bad libtool version, but I have no idea how to correct it. Whenever I have to debug an autotool-based build, a kitten dies somewhere: ~/projects/base-hsdis/sandbox ➔ make cd . && /bin/sh ./config.status config.h config.status: creating config.h make all-recursive Making all in libdisasm /bin/sh ../libtool --tag=CC --mode=compile gcc -DHAVE_CONFIG_H -I. -I.. -g -O2 -Wall -ggdb -MT ia32_implicit.lo -MD -MP -MF .deps/ia32_implicit.Tpo -c -o ia32_implicit.lo ia32_implicit.c ../libtool: line 818: X--tag=CC: command not found ../libtool: line 851: libtool: ignoring unknown tag : command not found ../libtool: line 818: X--mode=compile: command not found ../libtool: line 985: *** Warning: inferring the mode of operation is deprecated.: command not found ../libtool: line 986: *** Future versions of Libtool will require --mode=MODE be specified.: command not found ../libtool: line 1129: Xgcc: command not found ../libtool: line 1129: X-DHAVE_CONFIG_H: command not found ../libtool: line 1129: X-I.: command not found ../libtool: line 1129: X-I..: command not found ../libtool: line 1129: X-g: command not found ../libtool: line 1129: X-O2: command not found ../libtool: line 1129: X-Wall: command not found ../libtool: line 1129: X-ggdb: command not found ../libtool: line 1129: X-MT: command not found ../libtool: line 1129: Xia32_implicit.lo: command not found ../libtool: line 1129: X-MD: command not found ../libtool: line 1129: X-MP: command not found ../libtool: line 1129: X-MF: command not found ../libtool: line 1129: X.deps/ia32_implicit.Tpo: No such file or directory ../libtool: line 1129: X-c: command not found ../libtool: line 1181: Xia32_implicit.lo: command not found ../libtool: line 1186: libtool: compile: cannot determine name of library object from `': command not found make[2]: *** [ia32_implicit.lo] Error 1 make[1]: *** [all-recursive] Error 1 make: *** [all] Error 2 - Charlie -- You received this message because you are subscribed to the Google Groups "JVM Languages" group.
