Reid Spencer 65ba7501fc Implement printing of instruction result values when debug info is turned 
on. This helps to speed up the debugging time by showing computational
results as the program executes.

Reid Spencer 146281ce1a The wrapping behavior of part_set is not desirable. Adjust the

llvm-svn: 37036
 2007-05-14 16:50:20 +00:00
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.

 2007-05-14 14:31:17 +00:00
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.

llvm-svn: 37026
 2007-05-14 00:15:28 +00:00
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.

llvm-svn: 37019
 2007-05-13 17:30:11 +00:00
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

llvm-svn: 36991
 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.
