: Test is the same (pass) at both endpoints (2004-02-01-3.4,
: 2004-07-27-3.4), so there's nothing for me to do.

Broken on the mainline:
: Search converges between 2001-06-03-trunk (#22) and 2001-06-10-trunk (#23).

Fixed on the mainline:
: Search converges between 2003-06-04-trunk (#254) and 2003-06-05-trunk (#255).
So in my testing (on Phil's regression hunter) this is only a 3.3 regression but this was without -
march=pentiumpro which is what fixed it without using the driver (or something like that)

With using -march=pentiumpro:
: Search converges between 2004-04-20-trunk (#449) and 2004-05-01-trunk (#450).
This might still a bug on the mainline also but harder to get to as we get rid of some code before 
going into the RTL.

Moving the target to 3.4.2 per what Gaby said about regressions that are on both 3.3.x and 3.4.x.
