JVM Tools
You stumbled upon a page for engineers like us, who like to have the tools handy that help develop HotSpot JVM. One of such tools is the HotSpot disassembler library called hsdis (source code
available from OpenJDK), for which we provide binaries for the following platforms: Linux 64, Linux ARM64, Linux ARM32 HardFloat.
hsdis.so binaries
| Date | Platform | JDK | Library | SHA1 | Binutils |
|---|---|---|---|---|---|
| 2017-12-29 | Linux ARMv7l | 9 | hsdis-armv7l.so | 3721327284862e45c6757d6c7511c9989f80630c | 2.28 |
| 2017-06-22 | Linux x86-64 | 9 | hsdis-amd64.so | 73fe914734490666032b865aac53fc155196d558 | 2.28 |
| 2017-06-14 | Linux ARMv8 | 9 | hsdis-aarch64.so | 3de8038ea3799c47d03826e6d9286ce11d4f6c9d | 2.28 |
Note, when more recent binutils are used, the library knows more instructions.
Building hsdis.so
To build hsdis.so
- Download the following GNU source packages: m4 (fresh version for bison), bison, texinfo, binutils:
- install m4, bison, texinfo, but not binutils:
cd ..../configuremake ## on amd64 it'll probably require "make all64" insteadsudo make install
- scp openjdk 9 source tree tip, e.g. to get snapshot from cross-build tree use
zip -9 -r --exclude=*.hg* --exclude=*build* open9.zip open9
- unpack jdk sources
- unpack binutils as hotspot/src/share/tools/hsdis/build/binutils
- build the library:
cd hotspot/src/share/tools/hsdismake
- Get the image in build/linux-aarch64/
Known issues
Raspbian
'sudo make install' of m4 may not work, workaround is to install it elsewhere.
- For m4:
./configure --prefix=/home/pi/m4bin
- For bison
./configure M4=/home/pi/m4bin/bin/m4
