4971331b4f ARM: Mul and mla ignore the c and v flags, but we were setting them to 1. 2009-07-29 22:24:00 -07:00

b066e717f4 ARM: Fix an instruction in the cmpxchg kernel provided routine. 
The instruction was encoded as a load instead of the intended store.

c2da5bae17 ARM: Get rid of a stray line in the set_tls handler. 2009-07-29 00:17:20 -07:00

1e04b6281d ARM: Make the ARM native tracer stop M5 if control diverges. 
If the control flow of M5's executable and statetrace's target process get out
of sync even a little, there will be a LOT of output, very little of which
will be useful. There's also almost no hope for recovery. In those cases, we
might as well give up and not generate a huge, mostly worthless trace file.

a41e132007 ARM: Make native trace only print when registers are changing value. 
When registers have incorrect values but aren't actively changing, it's likely
they're not being modified at all. The fact that they're still wrong isn't
very important.
