Gabe Black b64d0bdeda X86: Fix condition code setting for signed multiplies with negative results. 2009-08-05 03:07:01 -07:00
Gabe Black 2914a8eb16 X86: Make the check for negative operands for sign multiply more direct. 2009-08-05 03:06:37 -07:00
Gabe Black e2e0ae576a X86: Make sure immediate values are truncated properly.
Register values will be "picked" which will assure they don't have junk beyond
the part we're using. Immediate values don't go through a similar process, so
we should truncate them explicitly.

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

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