Lauro Ramos Venancio 1b8d46ab21 Fix previous patch. GOTOFF can be used only when the symbol has internal 
linkage or hidden visibility.

Chris Lattner e49c974a7c implement a simple fneg optimization/propagation thing. This compiles: 
CodeGen/PowerPC/fneg.ll into:

_t4:
        fmul f0, f3, f4
        fmadd f1, f1, f2, f0
        blr

instead of:

_t4:
        fneg f0, f3
        fmul f0, f0, f4
        fmsub f1, f1, f2, f0
        blr

Evan Cheng 4c28ec187e Test for PR1406. 
llvm-svn: 37051
 2007-05-14 21:12:43 +00:00
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.

Evan Cheng fc2377d4ed When marking a register as being implicitly defined, make sure to clear its partial use info as well.

Lauro Ramos Venancio d705f5d51d Optimize PIC implementation. GOTOFF can be used when the symbol is defined 
and used in the same module.

Evan Cheng bc5c15276b Remove duplicated line. 
llvm-svn: 37040
 2007-05-14 18:03:45 +00:00
Reid Spencer 9cdab38520 Reverse last patch .. premature. Depends on uncommitted CBE patch. 
llvm-svn: 37039
 2007-05-14 17:58:52 +00:00
Reid Spencer 9c6a4d64aa Update this test to match the (corrected) output from the CBE. 
llvm-svn: 37038
 2007-05-14 17:56:39 +00:00
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.

llvm-svn: 37037
 2007-05-14 17:21:17 +00:00
Reid Spencer 146281ce1a The wrapping behavior of part_set is not desirable. Adjust the 
documentation to describe the desired behavior.

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.

Dan Gohman 8d40e4d965 Correct a few comments. 
llvm-svn: 37034
 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: 37033
 2007-05-14 14:25:08 +00:00
Dan Gohman 86110bdf06 Use templates for the GraphType for DefaultDOTGraphTraits' members instead 
of just using void*. This allows it to be used with graph adapters like
Inverse.

llvm-svn: 37032
 2007-05-14 14:23:27 +00:00
Dan Gohman 619bfa47e3 Add a addRequiredTransitiveID member function, which is to 
addRequiredTransitive as addRequiredID is to addRequired.

Reid Spencer 98ed7db7ab Make the results for the rotate functions correct when rotateAmt == 0. 
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.

llvm-svn: 37018
 2007-05-13 15:42:26 +00:00
Chris Lattner 8176a2f24e add initial description of llvm top-level stuff. 
llvm-svn: 37017
 2007-05-13 01:39:44 +00:00
Chris Lattner d72bb414b6 finish the description of the bitstream format. 
llvm-svn: 37016
 2007-05-13 00:59:52 +00:00
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.

llvm-svn: 37015
 2007-05-12 22:36:25 +00:00
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.

llvm-svn: 37010
 2007-05-12 18:01:57 +00:00
Reid Spencer 5d22b630af Add a test case for shl of APInt integers > 64 bits by 0 shift amount.
