MMTk port to SSCLI -> Documentation -> Requirements for RMTk -> Checking GCC 3.3 fix
This document explains how to check that a patched version of GCC 3.3 has been installed.
Download gcjsigsegv.tar.gz (1016 bytes), the source code for a program to test that GCC has been patched.
Use the following command to unpack the archive:
tar xzf gcjsigsegv.tar.gz
The build.sh shell script included with the test source code builds the test program. To run the script, use the following command from the gcjsigsegv directory:
If an error like:
./build.sh: line 6: gcj33: command not found
occurs, then GCJ was not installed correctly.
To run the test program, use the following command from the gcjsigsegv directory:
If GCC is patched then the output is similar to:
Using Java k = 5 *p = 5 Caught fault sig = 11 info = 0xbfbffa18 info->si_code = 12 Exiting
If GCC is not patched the output is:
Using Java Caught fault sig = 11 info = 0xc Exiting
The thing to look at is the value of info. If GCC is patched it will be a large number. If GCC is not patched it will be 0xc.
