Jakob Stoklund Olesen 13ce236c4c Insert code in the right location when lowering PowerPC atomics. 
This causes defs to dominate uses, no instructions after terminators, and other
goodness.

Jakob Stoklund Olesen 7067bff976 Use X0 instead of R0 for the zero register on ppc64. 
The 32-bit R0 cannot be used where a 64-bit register is expected.

Devang Patel f3292b2196 Revert r124611 - "Keep track of incoming argument's location while emitting LiveIns." 
In other words, do not keep track of argument's location.  The debugger (gdb) is not prepared to see line table entries for arguments. For the debugger, "second" line table entry marks beginning of function body.
This requires some coordination with debugger to get this working. 
 - The debugger needs to be aware of prolog_end attribute attached with line table entries.
 - The compiler needs to accurately mark prolog_end in line table entries (at -O0 and at -O1+)

Jeffrey Yasskin 9b43f33620 Change all self assignments X=X to (void)X, so that we can turn on a 
new gcc warning that complains on self-assignments and
self-initializations.

Chris Lattner 3e5fbd74ed rename MVT::Flag to MVT::Glue. "Flag" is a terrible name for 
something that just glues two nodes together, even if it is
sometimes used for flags.

Wesley Peck 527da1b6e2 Renaming ISD::BIT_CONVERT to ISD::BITCAST to better reflect the LLVM IR concept.

Chris Lattner dd6df84900 convert the operand bits into bitfields since they are all combinable in 
different ways.  Add $non_lazy_ptr support, and proper lowering for
global values.

Now all the ppc regression tests pass with the new instruction printer.

Chris Lattner edb9d84dcc add targetoperand flags for jump tables, constant pool and block address 
nodes to indicate when ha16/lo16 modifiers should be used.  This lets
us pass PowerPC/indirectbr.ll.

The one annoying thing about this patch is that the MCSymbolExpr isn't
expressive enough to represent ha16(label1-label2) which we need on
PowerPC.  I have a terrible hack in the meantime, but this will have
to be revisited at some point.

Last major conversion item left is global variable references.

Chris Lattner df8e17d80b implement support for the MO_DARWIN_STUB TargetOperand flag, 
and have isel apply to to call operands as required.  This allows
us to get $stub suffixes on label references on ppc/tiger with the
new instprinter, fixing two tests.  Only 2 to go.

Duncan Sands 71049f78ed In the calling convention logic, ValVT is always a legal type, 
and as such can be represented by an MVT - the more complicated
EVT is not needed.  Use MVT for ValVT everywhere.

 2010-11-04 10:49:57 +00:00
Duncan Sands f5dda01f33 Inside the calling convention logic LocVT is always a simple 
value type, so there is no point in passing it around using
an EVT.  Use the simpler MVT everywhere.  Rather than trying
to propagate this information maximally in all the code that
using the calling convention stuff, I chose to do a mainly
low impact change instead.

Jakob Stoklund Olesen 6c4353ecee PowerPC varargs functions store live-in registers on the stack. Make sure we use 
virtual registers for those stores since RegAllocFast requires that each live
physreg only be used once.

This fixes PR8357.

Chris Lattner d10babfd65 fix the expansion of va_arg instruction on PPC to know the arg 
alignment for PPC32/64, avoiding some masking operations.

llvm-gcc expands vaarg inline instead of using the instruction
so it has never hit this.

Chris Lattner 2510de2bea reimplement memcpy/memmove/memset lowering to use MachinePointerInfo 
instead of srcvalue/offset pairs.  This corrects SV info for mem 
operations whose size is > 32-bits.

Torok Edwin 31e90d2dd1 Use indirect calls in PowerPC JIT. 
See PR5201. There is no way to know if direct calls will be within the allowed
range for BL. Hence emit all calls as indirect when in JIT mode.
Without this long-running applications will fail to JIT on PowerPC with a
relocation failure.

Dale Johannesen ce97d55ad9 The hasMemory argument is irrelevant to how the argument 
for an "i" constraint should get lowered; PR 6309.  While
this argument was passed around a lot, this is the only
place it was used, so it goes away from a lot of other
places.

llvm-svn: 101977
 2010-04-21 01:34:56 +00:00
Dan Gohman 21cea8ac2e Use const qualifiers with TargetLowering. This eliminates several 
const_casts, and it reinforces the design of the Target classes being
immutable.

SelectionDAGISel::IsLegalToFold is now a static member function, because
PIC16 uses it in an unconventional way. There is more room for API
cleanup here.

And PIC16's AsmPrinter no longer uses TargetLowering.
