Anton Korobeynikov c5faeb82b5 Move X86 assembler printers into separate directory. This allows JIT-only users not to link it in (use 'x86codegen' llvm-config arg for this)

Chris Lattner 17f7165f84 Rework the routines that convert AP[S]Int into a string. Now, instead of 
returning an std::string by value, it fills in a SmallString/SmallVector
passed in.  This significantly reduces string thrashing in some cases.

More specifically, this:
 - Adds an operator<< and a print method for APInt that allows you to 
   directly send them to an ostream.
 - Reimplements APInt::toString to be much simpler and more efficient
   algorithmically in addition to not thrashing strings quite as much.

This speeds up llvm-dis on kc++ by 7%, and may also slightly speed up the
asmprinter.  This also fixes a bug I introduced into the asmwriter in a
previous patch w.r.t. alias printing.

Owen Anderson 4f6bf04616 Convert uses of std::vector in TargetInstrInfo to SmallVector. This change had to be propoagated down into all the targets and up into all clients of this API.

 2008-08-14 22:49:33 +00:00
Dan Gohman 65d83ccf26 Don't try to use the insertps instruction for vector 
element inserts with non-constant indices. This fixes
CodeGen/X86/vector-variable-idx.ll on machines that
have SSE4.1.

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.

rather than the absolute address if the target is within range.

Dale Johannesen d4a5e8f74a In the absence of a linker to build the GOT, use the 32-bit 
non_lazy_ptr mechanism on x86-64 Darwin JIT.  Fixes a bunch
of last night's failures.

Dale Johannesen dafdbf77b3 Some fixes for x86-64 JIT. Make it use small code 
model, except for external calls; this makes
addressing modes PC-relative.  Incomplete.

The assertion at the top of Emitter::runOnMachineFunction
was obviously bogus (always true) so I removed it.
If someone knows what the correct test should be to cover
all the various targets, please fix.
