Hi,
This is an update on the RTEMS trace linker being worked on and found in
the http://git.rtems.org/chrisj/rtl-host.git repo.
The following is a trace using the both_hello example in examples-v2
using the trace configuration file attached:
$ sparc-rtems4.11-run both_hello.exe

I also attach the waf script I used to build the example. You need to
build and install the rtl-host code to get a working rtems-tld.
The 3 threads created are the Init, POSIX_Init and IDLE No code in RTEMS
was altered to do this.
