Chris Lattner 89261502cb make -show-inst be formatted a bit nicer. Before: 
movl	$3735928559, a          ## inst: <MCInst 1273 <MCOperand Reg:0> <MCOperand Imm:1> <MCOperand Reg:0> <MCOperand Expr:(a)> <MCOperand Reg:0> <MCOperand Expr:(3735928559)>>

after:

Lang Hames 48121948dc Fixed a bug in the PBQP allocator's findCoalesces method. 
Previously spill registers, whose def indexes are not defined, would sometimes be improperly marked as coalescable with conflicting registers. The new findCoalesces routine conservatively assumes that any register with at least one undefined def is not coalescable with any register it interferes with.

 2010-02-09 00:49:22 +00:00
Lang Hames 7b1e683975 Added copy sensible construction & assignment to PBQP graphs and fixed a memory access bug in the heuristic solver.

Lang Hames 4695741312 Changed the definition of an "invalid" slot to include the empty & tombstone values, but not zero.

Eric Christopher 9f85e7eb16 Add a new pass to do llvm.objsize lowering using SCEV. 
Initial skeleton and SCEVUnknown lowering implemented,
the rest should come relatively quickly.  Move testcase
to new directory.

Move pass to right before SimplifyLibCalls - which is
moved down a bit so we can take advantage of a few opts.

 2010-02-09 00:11:10 +00:00
Chris Lattner a460edca79 enhance bits_storage to work with enums by using a c-style 
cast instead of reinterpret_cast, fixing PR6243.  Apparently
reinterpret_cast and I aren't getting along today.

 2010-02-09 00:05:45 +00:00
Dan Gohman 227077d1be Implement AsmPrinter support for several more operators which have 
direct MCExpr equivalents. Don't use MCExpr::Shr because it isn't
consistent between targets.

llvm-svn: 95620
 2010-02-09 00:02:37 +00:00
Dan Gohman 9a9d9ea7bc Document that MCExpr::Mod is actually remainder. 
Document that MCExpr::Div, Mod, and the comparison operators are all
signed operators.

Document that the comparison operators' results are target-dependent.

Document that the behavior of shr is target-dependent.

Sean Callanan cb956d93b8 Added header file declarations and .exports entries 
for the new APIs offered by the enhanced disassembler
for inspecting operands.

Jim Grosbach a570d05228 tighten up eh.setjmp sequence a bit. 
llvm-svn: 95603
 2010-02-08 23:22:00 +00:00
Chris Lattner ebc970e4eb now that @GOTOFF is no longer represented as a suffix on a 
MCSymbol, we can remove the 'suffix' argument of 
GetBlockAddressSymbol.  Do so.

Chris Lattner 99777dd78f switch the rest of the "@ concatentation" logic in the X86 
backend to use X86MCTargetExpr, simplifying a bunch of code.

llvm-svn: 95595
 2010-02-08 22:52:47 +00:00
Sean Callanan 4d16049c61 Fixed the AT&T AsmLexer to report the proper strings 
for register tokens.  Before, if it encountered
'%al,' it would report 'al,' as the token.  Now it
correctly reports '%al'.

llvm-svn: 95594
 2010-02-08 22:50:23 +00:00
Chris Lattner b8479fb309 switch ELF @GOTOFF references to use X86MCTargetExpr. 
llvm-svn: 95593
 2010-02-08 22:33:55 +00:00
Dan Gohman e51b57bee0 ConstantFoldConstantExpression can theoretically return the original 
expression; don't go into an infinite loop if it does.

llvm-svn: 95591
 2010-02-08 22:19:11 +00:00
Chris Lattner b6b2164e28 add an x86 implementation of MCTargetExpr for 
representing @GOT and friends.  Use it for
personality references as a first use.

Chris Lattner 54d88f1759 don't make hte dtor private or we can't construct the class. 
llvm-svn: 95587
 2010-02-08 22:07:36 +00:00
Chris Lattner cddc4c17b1 use a c-style cast instead of reinterpret-cast, as sometimes the 
cast needs to adjust for a vtable pointer when going from base to
derived type (when the base doesn't have a vtable but the
derived type does).

llvm-svn: 95585
 2010-02-08 22:05:38 +00:00
Johnny Chen 9e60686a83 Add VCVTR (between floating-point and integer, VFP) for disassembly purpose. 
The 'R' suffix means the to-integer operations use the rounding mode specified
by the FPSCR, encoded as Inst{7} = 0.

A8.6.295

Dan Gohman 4268d6a7c3 When CodeGen'ing unoptimized code, there may be unfolded constant expressions 
in global initializers. Instead of aborting, attempt to fold them on the
spot. If folding succeeds, emit the folded expression instead.

This fixes PR6255.

llvm-svn: 95583
 2010-02-08 22:02:38 +00:00
Dan Gohman 6f9646e1c5 Add const qualifiers.

 2010-02-08 22:00:06 +00:00
Dale Johannesen 120cfe23a7 Apply the 95471 fix to SelectionDAGBuilder as well; 
we can get in here if FastISel gives up in a block.
(Actually the two copies of this need to be unified.  Later.)

 2010-02-08 21:53:27 +00:00
Dan Gohman bd374da130 In guaranteed tailcall mode, don't decline the tailcall optimization 
for blocks ending in "unreachable".

llvm-svn: 95565
 2010-02-08 20:34:14 +00:00
Dan Gohman 3464a5b609 Rename the PerformTailCallOpt variable to GuaranteedTailCallOpt to reflect 
its current purpose.

llvm-svn: 95564
 2010-02-08 20:27:50 +00:00
Johnny Chen beb1238a85 Add VCMP (VFP floating-point compare without 'E' bit set) for disassembly purpose. 
llvm-svn: 95560
 2010-02-08 19:41:48 +00:00
Chris Lattner 38d022efe9 add scaffolding for target-specific MCExprs. 
llvm-svn: 95559
 2010-02-08 19:41:07 +00:00
Duncan Sands e77bebc4ba Flesh out the list of predicates, for those who like this style. I was 
looking for isPointer, and added the rest for uniformity.

Daniel Dunbar ff7e95878f ImmutableIntervalMap: Fix for unqualified lookup into dependent base class, done 
by clang's -fixit! :)

llvm-svn: 95551
 2010-02-08 18:08:46 +00:00
Johnny Chen c7e606f132 Added VMOVRRS/VMOVSRR to ARMInstrVFP.td for disassembly purpose. 
A8.6.331 VMOV (between two ARM core registers and two single-precision registers)

llvm-svn: 95548
