Devang Patel 52dc07b01a Use DenseMap. Patch by Pratik Solanki. 
llvm-svn: 54792
 2008-08-14 21:31:10 +00:00
Ted Kremenek 5ba24b7e08 Removed redundant ctor.

Ted Kremenek db7dd9cd15 Migrated retain/release checker to use the Generic Data Map in GRState (instead 
of using CheckerState).

Removed CheckerState from GRState.

Added class GRStateRef which wraps GRState* and GRStateManager*. This is handy
for generating new states with a single handle.

Added member template set/get functions to GRStateRef/GRState/GRStateManager for
accessing the Generic Data Map.

Owen Anderson fa8b2ea41b Speed up addRegisterDead by adding more fast checks before performing the expensive 
subregister query, and by increasing the size of the subregister hashtable so
that there are fewer collisions.

Dan Gohman 8de6d22392 Use empty() instead of begin() == end().

Matthijs Kooijman 4801bd41cf Replace two for loops with while(!X->use_empty()) loops. This prevents 
invalidating the iterator by deleting the current use. This fixes a segfault on
64 bit linux reported in PR2675.

Also remove an unneeded if.

Chris Lattner 89d6c9f698 Make diagnostics relating to the callee hilight just the callee 
and put the caret on the ()'s.  e.g. produces:

t.c:13:9: error: called object is not a function or function pointer
  ((B)a)();
  ~~~~~~^

instead of:

t.c:13:3: error: called object is not a function or function pointer
  ((B)a)();
  ^~~~~~~~

Daniel Dunbar c4baa06d15 Add GetAddrOfConstantCString method 
- Returns addr of constant for argument + '\0'.
 - I couldn't think of a better name.
 - Move appropriate users of GetAddrOfConstantString to this.

Rename getStringForStringLiteral to GetStringForStringLiteral.

Add GetAddrOfConstantStringFromLiteral
 - This combines GetAddrOfConstantString and
   GetStringForStringLiteral. This method can be, but is not yet, more
   efficient.

Change GetAddrOfConstantString to not add terminating '\0'
 - <rdar://problem/6140956>

Dan Gohman 6134fbccef Fix a bogus srem rule - a negative value srem'd by a power-of-2 
can have a non-negative result; for example, -16%16 is 0. Also,
clarify the related comments. This fixes PR2670.

 2008-08-13 22:08:30 +00:00
Dan Gohman 7e3c392248 Allow SelectionDAG to create EXTRACT_VECTOR_ELT nodes with 
non-constant indices. Only a few of the peephole checks require
a constant index.

llvm-svn: 54764
 2008-08-13 21:51:37 +00:00
Owen Anderson 51f689a652 Make the allocation of LiveIntervals explicit, rather than holding them in the r2iMap_ by value. This will prevent references to them from being invalidated 
if the map is changed.

Ted Kremenek 16306107cf Renamed GRState::CheckerStatePrinter to GRState::Printer. 
Updated checker state printer interface to allow transfer functions to return an arbitrary number of GRState::Printers.

Dan Gohman 8ded5d5884 Fix SCCP's handling of struct value loads and stores. SCCP doesn't 
track individual leaf values in such cases, so it needs to treat
struct values as normal values in this case.

Duncan Sands ea68a6ccdf Teach constant folding that an inttoptr of a 
ptrtoint can be turned into a bitcast if the
integer is at least as wide as a pointer.

Dan Gohman b2226e21c3 Initial checkin of the new "fast" instruction selection support. See 
the comments in FastISelEmitter.cpp for details on what this is.
This is currently experimental and unusable.

Steve Naroff eb03dace87 Sema::ActOnStartProtocolInterface(): Make sure the protocol decl has a valid start location. 
The following case resulted in an invalid start location:

@protocol Buggy;

Bruno Cardoso Lopes 92c64ae2d0 Removed SELECT_CC custom lowering. This is not needed anymore, the SELECT node 
is lowered properly and covers everything LowerSELECT_CC did.
Added method printUnsignedImm in AsmPrinter to print uimm16 operands. This
avoid the ugly instruction by instruction checking in printOperand.
Added a swap instruction present in the allegrex core.
Added two conditional instructions present in the allegrex core : MOVZ and MOVN.
They both allow a more efficient SELECT operation for integers.
Also added SELECT patterns to optimize MOVZ and MOVN usage.
The brcond and setcc patterns were cleaned: redundant and suboptimal patterns
were
removed. The suboptimals were replaced by more efficient ones.
Fixed some instructions that were using immZExt16 instead of immSExt16.
