100N/A'hsdis': A HotSpot plugin for disassembling dynamically generated code.
100N/Aare built independently of the HotSpot JVM.
100N/ATo use the plugin with a JVM, you need a new version that can load it.
100N/AIf the product mode of your JVM does not accept -XX:+PrintAssembly,
100N/Ayou do not have a version that is new enough.
720N/ATo build this project you a copy of GNU binutils to build against. It
720N/Ais known to work with binutils 2.17 and binutils 2.19.1. Download a
720N/Aone of it's mirrors. Builds targetting windows should use at least
720N/A2.19 and currently requires the use of a cross compiler.
720N/Aspecify it's location to the makefile using BINTUILS=path. It will
720N/Aconfigure binutils and build it first and then build and link the
720N/Adisasembly adapter. Make all will build the default target for your
720N/Aplatform. If you platform support both 32 and 64 simultaneously then
720N/A"make both" will build them both at once. "make all64" will
720N/Aexplicitly build the 64 bit version. By default this will build the
720N/Adisassembler library only. If you build demo it will build a demo
720N/Aprogram that attempts to exercise the library.
720N/AIn theory this should be buildable on Windows but getting a working
720N/AGNU build environment on Windows has proven difficult. MINGW should
720N/Abe able to do it but at the time of this writing I was unable to get
720N/Athis working. Instead you can use the mingw cross compiler on linux
720N/Ato produce the windows binaries. For 32-bit windows you can install
720N/Amingw32 using your package manager and it will be added to your path
720N/Aautomatically. For 64-bit you need to download the 64 bit mingw from
720N/Acomplete toolchain and unpack it somewhere. Put the bin directory of
720N/Athe toolchain in your path. The mingw installs contain cross compile
720N/Aversions of gcc that are named with a prefix to indicate what they are
720N/Atargetting and you must tell the Makefile which one to use. This
720N/Ashould either be i586-mingw32msvc or x86_64-pc-mingw32 depending on
720N/Awhich on you are targetting and there should be a version of gcc in
720N/Ayour path named i586-mingw32msvc-gcc or x86_64-pc-mingw32-gcc. Tell
720N/Athe makefile what prefix to use to find the mingw tools by using
720N/Awill build the Win32 cross compiled version of hsdis based on 2.19.1.
2619N/Ainstall them on your LD_LIBRARY_PATH, or inside of your
JRE/JDK. The
2619N/A4. hsdis-<arch>.so (using LD_LIBRARY_PATH)
2619N/ANote that there's a bug in hotspot versions prior to hs22 that causes
2619N/Asteps 2 and 3 to fail when used with JDK7.
100N/A dargs='-XX:+UnlockDiagnosticVMOptions -XX:+PrintAssembly'
100N/A dargs=$dargs' -XX:PrintAssemblyOptions=hsdis-print-bytes'
100N/AIf the product mode of the JVM does not accept -XX:+PrintAssembly,
100N/Ayou do not have a version new enough to use the hsdis plugin.
