Dale Johannesen c5283ecd6f long double patch 2 of N. Handle it in TargetData. 
(I've tried to get the info right for all targets,
but I'm not expert on all of them - check yours.)

Evan Cheng 9081ab8127 Oops. These stores actually produce results.

Evan Cheng 94b5a80b93 Change instruction description to split OperandList into OutOperandList and 
InOperandList. This gives one piece of important information: # of results
produced by an instruction.
An example of the change:
def ADD32rr  : I<0x01, MRMDestReg, (ops GR32:$dst, GR32:$src1, GR32:$src2),
                 "add{l} {$src2, $dst|$dst, $src2}",
                 [(set GR32:$dst, (add GR32:$src1, GR32:$src2))]>;
=>
def ADD32rr  : I<0x01, MRMDestReg, (outs GR32:$dst), (ins GR32:$src1, GR32:$src2),
                 "add{l} {$src2, $dst|$dst, $src2}",
                 [(set GR32:$dst, (add GR32:$src1, GR32:$src2))]>;

Anton Korobeynikov 383a324735 Long live the exception handling! 
This patch fills the last necessary bits to enable exceptions
handling in LLVM. Currently only on x86-32/linux.

In fact, this patch adds necessary intrinsics (and their lowering) which
represent really weird target-specific gcc builtins used inside unwinder.

After corresponding llvm-gcc patch will land (easy) exceptions should be
more or less workable. However, exceptions handling support should not be 
thought as 'finished': I expect many small and not so small glitches
everywhere.

Dan Gohman f8f531bf69 Change getCopyToParts and getCopyFromParts to always use target-endian 
register ordering, for both physical and virtual registers. Update the PPC
target lowering for calls to expect registers for the call result to
already be in target order.

Chris Lattner 517290ae52 The various "getModuleMatchQuality" implementations should return 
zero if they see a target triple they don't understand.

Dan Gohman 309d3d51b3 Move ComputeMaskedBits, MaskedValueIsZero, and ComputeNumSignBits from 
TargetLowering to SelectionDAG so that they have more convenient
access to the current DAG, in preparation for the ValueType routines
being changed from standalone functions to members of SelectionDAG for
the pre-legalize vector type changes.

Dale Johannesen 82810c8a13 Make tail merging the default, except on powerPC. There was no prior art 
for a target-dependent default with a command-line override; this way
should be generally usable.

 2007-05-03 01:11:54 +00:00
Devang Patel e95c6ad802 Use 'static const char' instead of 'static const int'. 
Due to darwin gcc bug, one version of darwin linker coalesces
static const int, which defauts PassID based pass identification.
