Jakob Stoklund Olesen 4d6eafa138 Change the Spiller interface to take a LiveRangeEdit reference. 
This makes it possible to register delegates and get callbacks when the spiller
edits live ranges.

Ted Kremenek f9d8290af1 Rework interaction between AnalysisContext and CFG::BuildOptions to keep a BuildOptions object around instead of keeping a copy of the flags. 
Moreover, change AnalysisContext to use an OwningPtr for created analysis objects instead
of directly managing them.

Finally, add a 'forcedBlkExprs' entry to CFG::BuildOptions that will be used by the
CFGBuilder to force specific expressions to be block-level expressions.

Devang Patel fa31d38aad Introduce DebugInfoProbe. This is used to monitor how llvm optimizer is treating debugging information. 
It generates output that lools like

8 times line number info lost by Scalar Replacement of Aggregates (SSAUp) 
1 times line number info lost by Simplify well-known library calls 
12 times variable info lost by Jump Threading

Johnny Chen a460316d81 Add test cases for Python SBThread.StepOut() API by stepping out of a malloc call where the call site is at function b(). 
Verifies that after the thread.StepOut(), we are at the correct line within function b.

Evan Cheng ca9a936332 Change the definition of TargetRegisterInfo::getCrossCopyRegClass to be more 
flexible.

If it returns a register class that's different from the input, then that's the
register class used for cross-register class copies.
If it returns a register class that's the same as the input, then no cross-
register class copies are needed (normal copies would do).
If it returns null, then it's not at all possible to copy registers of the
specified register class.

Johnny Chen 9363d41f14 LLVM combines the offset mode of A8.6.199 A1 & A2 into STRBT. 
The insufficient encoding information of the combined instruction confuses the decoder wrt
UQADD16.  Add extra logic to recover from that.

Fixed an assert reported by Sean Callanan

Jakob Stoklund Olesen d0db705256 Make physreg coalescing independent on the number of uses of the virtual register. 
The damage done by physreg coalescing only depends on the number of instructions
the extended physreg live range covers. This fixes PR9438.

The heuristic is still luck-based, and physreg coalescing really should be
disabled completely. We need a register allocator with better hinting support
before that is possible.

Convert a test to FileCheck and force spilling by inserting an extra call. The
previous spilling behavior was dependent on misguided physreg coalescing
decisions.

 2011-03-09 19:27:06 +00:00
Jakob Stoklund Olesen 456e104c13 Delete a test case that is very sensitive to coalescer behavior. 
The test is derived from an old miscompilation of
MultiSource/Benchmarks/VersaBench/8b10b which is run regularly, so we are not
losing coverage.
