I released froofyJIT 0.26.
Also, I experimented with using froofyJIT to speed up TiMidity++ -- profiling revealed that when processing Rakhmaninov's G minor prelude, it was spending ~1/4 of its time in do_ch_freeverb(), which is static optimization hell. After some hacking, here's the result: a tidy big patch which reduces the running time on this file by ~4%.
The patch probably isn't suitable for the TiMidity++ mainline though, especially since it's in C++, while the rest of the TiMidity++ code is in ye olde C.
Update: the patch is now stashed in the froofyJIT 0.27 tarball.
