I guess some serious whacking is due.

The compiler adds two jumps when the parameter changes due to
(h -softvec) instead of (h, softvec) ????

Dude, you can't be serious.

If you would have asked about the compiler version I'm using and told
me about the compiler version you are using, then I could take that
answer somehow serious.

It still would miss the "Uhhhh, your compiler creates crap code"
alert, because that double jump is seriously broken and braindead.

And I tell you more about this. You are going to piss off a lot of
users of distro compilers because they will set CC_HAVE_ASM_GOTO
happily and create the code I posted. Which will break the tracer no
matter what.

So you tracer maniacs happily played with some experimental compiler
stuff w/o even testing your crap against something which ships with
distros or is the reference 4.5 compiler on ?

I prefer you sending a patch to disable this, until it's sorted out,
unless you want me to add some really outrageous changelog to the
patch I'm going to put into tip tomorrow night, ok ?
