| jrose@535 | 24 | 'hsdis': A HotSpot plugin for disassembling dynamically generated code. |
| jrose@535 | 25 | |
| jrose@535 | 26 | The files in this directory (Makefile, hsdis.[ch], hsdis-demo.c) |
| jrose@535 | 27 | are built independently of the HotSpot JVM. |
| jrose@535 | 28 | |
| jrose@535 | 29 | To use the plugin with a JVM, you need a new version that can load it. |
| jrose@535 | 30 | If the product mode of your JVM does not accept -XX:+PrintAssembly, |
| jrose@535 | 31 | you do not have a version that is new enough. |
| jrose@535 | 32 | |
| jrose@535 | 33 | * Building |
| jrose@535 | 34 | |
| never@1155 | 35 | To build this project you a copy of GNU binutils to build against. It |
| never@1155 | 36 | is known to work with binutils 2.17 and binutils 2.19.1. Download a |
| never@1155 | 37 | copy of the software from http://directory.fsf.org/project/binutils or |
| never@1155 | 38 | one of it's mirrors. Builds targetting windows should use at least |
| never@1155 | 39 | 2.19 and currently requires the use of a cross compiler. |
| jrose@535 | 40 | |
| never@1155 | 41 | The makefile looks for the sources in build/binutils or you can |
| never@1155 | 42 | specify it's location to the makefile using BINTUILS=path. It will |
| never@1155 | 43 | configure binutils and build it first and then build and link the |
| never@1155 | 44 | disasembly adapter. Make all will build the default target for your |
| never@1155 | 45 | platform. If you platform support both 32 and 64 simultaneously then |
| never@1155 | 46 | "make both" will build them both at once. "make all64" will |
| never@1155 | 47 | explicitly build the 64 bit version. By default this will build the |
| never@1155 | 48 | disassembler library only. If you build demo it will build a demo |
| never@1155 | 49 | program that attempts to exercise the library. |
| jrose@535 | 50 | |
| never@1155 | 51 | Windows |
| jrose@535 | 52 | |
| never@1155 | 53 | In theory this should be buildable on Windows but getting a working |
| never@1155 | 54 | GNU build environment on Windows has proven difficult. MINGW should |
| never@1155 | 55 | be able to do it but at the time of this writing I was unable to get |
| never@1155 | 56 | this working. Instead you can use the mingw cross compiler on linux |
| never@1155 | 57 | to produce the windows binaries. For 32-bit windows you can install |
| never@1155 | 58 | mingw32 using your package manager and it will be added to your path |
| never@1155 | 59 | automatically. For 64-bit you need to download the 64 bit mingw from |
| never@1155 | 60 | http://sourceforge.net/projects/mingw-w64. Grab a copy of the |
| never@1155 | 61 | complete toolchain and unpack it somewhere. Put the bin directory of |
| never@1155 | 62 | the toolchain in your path. The mingw installs contain cross compile |
| never@1155 | 63 | versions of gcc that are named with a prefix to indicate what they are |
| never@1155 | 64 | targetting and you must tell the Makefile which one to use. This |
| never@1155 | 65 | should either be i586-mingw32msvc or x86_64-pc-mingw32 depending on |
| never@1155 | 66 | which on you are targetting and there should be a version of gcc in |
| never@1155 | 67 | your path named i586-mingw32msvc-gcc or x86_64-pc-mingw32-gcc. Tell |
| never@1155 | 68 | the makefile what prefix to use to find the mingw tools by using |
| never@1155 | 69 | MINGW=. For example: |
| jrose@535 | 70 | |
| never@1155 | 71 | make MINGW=i586-mingw32msvc BINTUILS=build/binutils-2.19.1 |
| jrose@535 | 72 | |
| never@1155 | 73 | will build the Win32 cross compiled version of hsdis based on 2.19.1. |
| jrose@535 | 74 | |
| jrose@535 | 75 | * Installing |
| jrose@535 | 76 | |
| never@1155 | 77 | Products are named like build/$OS-$LIBARCH/hsdis-$LIBARCH.so. You can |
| never@2991 | 78 | install them on your LD_LIBRARY_PATH, or inside of your JRE/JDK. The |
| never@2991 | 79 | search path in the JVM is: |
| never@2991 | 80 | |
| never@2991 | 81 | 1. <home>/jre/lib/<arch>/<vm>/libhsdis-<arch>.so |
| never@2991 | 82 | 2. <home>/jre/lib/<arch>/<vm>/hsdis-<arch>.so |
| never@2991 | 83 | 3. <home>/jre/lib/<arch>/hsdis-<arch>.so |
| never@2991 | 84 | 4. hsdis-<arch>.so (using LD_LIBRARY_PATH) |
| never@2991 | 85 | |
| never@2991 | 86 | Note that there's a bug in hotspot versions prior to hs22 that causes |
| never@2991 | 87 | steps 2 and 3 to fail when used with JDK7. |
| jrose@535 | 88 | |
| jrose@535 | 89 | Now test: |
| never@1155 | 90 | |
| never@1155 | 91 | export LD_LIBRARY_PATH .../hsdis/build/$OS-$LIBARCH:$LD_LIBRARY_PATH |
| jrose@535 | 92 | dargs='-XX:+UnlockDiagnosticVMOptions -XX:+PrintAssembly' |
| jrose@535 | 93 | dargs=$dargs' -XX:PrintAssemblyOptions=hsdis-print-bytes' |
| jrose@535 | 94 | java $dargs -Xbatch CompileCommand=print,*String.hashCode HelloWorld |
| jrose@535 | 95 | |
| jrose@535 | 96 | If the product mode of the JVM does not accept -XX:+PrintAssembly, |
| jrose@535 | 97 | you do not have a version new enough to use the hsdis plugin. |
