Hello

I'm continuing on my quest to get the SPEC2000 benchmarks running under 
sparc32-linux-user (so far 8 out of 48 work).

Many of the benchmarks die early on with the following error:

     /fusion/research4/vince/qemu/svn/tcg/tcg.c:1455: tcg fatal error

This error is caused when tcg_reg_alloc_mov() is called but ts->val_type
is equal to 0 (which is TEMP_VAL_DEAD). So maybe the optimizer is 
optimizing away something that it shouldn't?

This happens in a block with multiple calls to the SPARC "mulscc"
instruction which is a complicated instruction, so maybe this is finding 
an obscure corner case.

I've attached a very small sample program that exhibits the bug when 
run with ./sparc32-linux-user/qemu-sparc32plus

Thanks for any help

Vince
