Evan Cheng c690cba7d9 Fix for PR1406:
v1 =
r2 = move v1
   = op r2<kill>
...
r2 = move v1
   = op r2<kill>

Clear the first r2 kill if v1 and r2 are joined.

Reid Spencer 764ae2a21b Give names to the final result values of the part_set computations. This
just aids in readability and debugability of the output. No functional change.

Reid Spencer 146281ce1a The wrapping behavior of part_set is not desirable. Adjust the
documentation to describe the desired behavior.

Reid Spencer 70845c05e4 Revise definition of part_select. The wrapping behavior is not useful so
in the reverse case the only difference is that the bits are returned in
reverse order.

Dan Gohman 90d97ac1e6 Add passes -view-cfg and -view-cfg-only that are like -print-cfg and
-print-cfg-only except they use the ViewCFG function, which displays the
CFG rendered with graphviz with gv.

Reid Spencer 4c50b52f63 Add some things needed by the llvm-gcc version supporting bit accurate integer
types:
1. Functions to compute div/rem at the same time.
2. Further assurance that an APInt with 0 bitwidth cannot be constructed.
3. Left and right rotate operations.
4. An exactLogBase2 function which requires an exact power of two or it
   returns -1.

Anton Korobeynikov 1ee0c8d563 Emit function debug frames in one atom. This will prevent us from generating incorrect assembler in case of both
debug information & exception information presented.

Anton Korobeynikov bbaf55448b Emit multiple common EH frames for multiple (including blank) personality
functions. This partly fixes PR1414: now we're restricted only to one
personality function per eh frame, not per module. Further work on
"multiple personalities" topic needs representative example.

Anton Korobeynikov 13da17843c More DWARF-related things cleanup:
1. Fix PR1380
2. Apply Duncan's patch from PR1410
3. Insert workaround for "one personality function per module" as noted in PR1414
4. Emit correct debug frames for x86/linux. This partly fixes DebugInfo/2006-11-06-StackTrace.cpp: stack trace is
shown correctly, but arguments for function on top of stack are displayed incorrectly.

Reid Spencer 81ee020f64 Fix shl to produce the correct result when the bitwidth is > 64 and the
shift amount is 0. Previously this code would do a lshr by the bit width
which can lead to incorrect results.

2007-05-11 20:59:29 +00:00
Dan Gohman 2980d9da45 This patch extends the LoopUnroll pass to be able to unroll loops
with unknown trip counts. This is left off by default, and a
command-line option enables it. It also begins to separate loop
unrolling into a utility routine; eventually it might be made usable
from other passes.

It currently works by inserting conditional branches between each
unrolled iteration, unless it proves that the trip count is a
multiple of a constant integer > 1, which it currently only does in
the rare case that the trip count expression is a Mul operator with
a ConstantInt operand. Eventually this information might be provided
by other sources, for example by a pass that peels/splits the loop
for this purpose.
