Alexis Hunt 483cf24547 Make all fstream tests use tmpnam if creating files, rather than 
hard-coded names.

Owen Anderson 83c6c4f30e Revamp our handling of tLDMIA[_UPD] and tSTMIA[_UPD] to avoid having multiple instructions with the same encoding. This resolves another conflict when bringing up the new-style disassembler.

Jeffrey Yasskin 7a16288157 Add APInt(numBits, ArrayRef<uint64_t> bigVal) constructor to prevent future ambiguity 
errors like the one corrected by r135261.  Migrate all LLVM callers of the old

Evan Cheng b505ace101 MCContext now takes MCRegisterInfo. 
llvm-svn: 135425
 2011-07-18 20:57:51 +00:00
Evan Cheng d60fa58ba1 Sink getDwarfRegNum, getLLVMRegNum, getSEHRegNum from TargetRegisterInfo down 
to MCRegisterInfo. Also initialize the mapping at construction time.

This patch eliminate TargetRegisterInfo from TargetAsmInfo. It's another step
towards fixing the layering violation.

Devang Patel 4dc76f2438 During bottom up fast-isel, instructions emitted to materalize registers are at top of basic block and do not have debug location. This may misguide debugger while entering the basic block and sometimes debugger provides semi useful view of current location to developer by picking up previous known location as current location. Assign a sensible location to the first instruction in a basic block, if it does not have one location derived from source file, so that debugger can provide meaningful user experience to developers in edge cases.

Andrew Trick 7da2417c8a indvars: LinearFunctionTestReplace for non-canonical IVs. 
For -disable-iv-rewrite, perform LFTR without generating a new
"canonical" induction variable. Instead find the "best" existing
induction variable for use in the loop exit test and compute the final
value of that IV for use in the new loop exit test. In short,
convert to a simple eq/ne exit test as long as it's cheap to do so.

Akira Hatanaka 27292638bd Set mayLoad or mayStore flags for SC and LL in order to prevent LICM from 
moving them out of the loop. Previously, stores and loads to a stack frame
object were inserted to accomplish this. Remove the code that was needed to do
this. Patch by Sasa Stankovic.

Owen Anderson 64d53620aa Re-apply r135319 with a fix for the constant island pass. 
Original Log: Get rid of the separate opcodes for the Darwin versions of tBL, tBLXi, and tBLXr, using pseudo-instructions to lower to the single final opcode.  Update the ARM disassembler for this change.

Jakob Stoklund Olesen c45d38e14a Fix a crash when building 177.mesa for armv6. 
When splitting a live range immediately before an LDR_POST instruction
that redefines the address register, make sure to use the correct value
number in leaveIntvBefore.

We need the value number entering the instruction.

Andrew Trick a27d8b183a indvars: Added isHighCostExpansion. Avoid generating extra ops in the 
preheader for the sole purpose of LFTR, since LFTR itself is usually not
a clear optimization.

Alexis Hunt f3ff971561 Give A an explicitly non-throwing destructor so that B's destructor is 
itself non-throwing.  Since nested_exception's destructor is
non-throwing, if B's destructor is not, this causes an error in C++03
mode due to the overriding function having a more lax specification.
This did not occur in C++0x mode as A's destructor was implicitly
non-throwing.

Jakob Stoklund Olesen abcfdcea5c Intern all RecTy subclass instances to avoid duplicates. 
Make all of the RecTy constructors private, and use get() factory
methods instead. Return singleton instances when it makes sense.

ListTy instance pointers are stored in the element RecTy instance.

BitsRecTy instance pointers, one per length, are stored in a static vector.

Also unique DefInit instances. A Record has a unique DefInit which
has a unique RecordRecTy instance.

This saves some 200k-300k RecTy allocations when parsing ARM.td. It
reduces TableGen's heap usage by almost 50%.

Frits van Bommel 1b3ee75077 Hopefully fix some GCC-based buildbots. GCC apparently decays the array to a pointer here before overload resolution, so construct with an explicit length instead.

Frits van Bommel 717d7edd3e Migrate LLVM and Clang to use the new makeArrayRef(...) functions where previously explicit non-default constructors were used. 
Mostly mechanical with some manual reformatting.

 2011-07-18 12:00:32 +00:00
Frits van Bommel 23db45e99c Introduce the 'makeArrayRef(...)' family of functions, which fills a similar role for ArrayRef<> as std::make_pair() fills for std::pair<>: they return the right instantiation of ArrayRef<T> based on the types of the parameters. 
They mostly mirror the ArrayRef constructors, with two exceptions:
 * There's no function mirroring the default constructor because it wouldn't have any parameters to deduce the right ArrayRef<T> from.
 * There's an explicit SmallVector<T> overload in addition to the SmallVectorImpl<T> overload. Without it, the single-element overload would try to create an ArrayRef<Smallvector<T> > because it's a better match according to the overloading rules. (And both overloads are used in the current tree, so neither is redundant)
