Sanjiv Gupta 44ea053a49 Emit .line debug directives for stoppoints. The debug location is retrieved by the MachineInstr itself, rather than by custom handling the DBG_STOPPOINT nodes.

Sanjiv Gupta 4b489c75c2 Handle indirect function calls. 
Every function has the address of its frame in the beginning of code section.
The frame address is retrieved and used to pass arguments.

Sanjiv Gupta 0b08df8c09 Map stack based frameindices for spills to zero based indices that can be accessed based on an external symbol defining the location of temporary data for a function. For example: we have spill slots addressed as foo.tmp + 0, foo.tmp + 1 etc.

Sanjiv Gupta cc841a3810 To convert the StopPoint insn into an assembler directive by ISel, we need to have access to the line number field. So we convert that info as an operand by custom handling DBG_STOPPOINT in legalize.

Sanjiv Gupta 1e8860a8f5 Params are not being generated as static globals now. The caller passes them onto the callee's stack directly and the callee loads the argvals from its own stack. Clang generated frameindexes validatd by recalculating the stack as if all frameindexes represent 1-byte slots.

Evan Cheng 5e5a63cf8f CodeGen still defaults to non-verbose asm, but llc now overrides it and default to verbose.

Sanjiv Gupta f883419b2f Banksel optimization is now based on the section names of symbols, since the symbols in one section will always be put into one bank.

Bill Wendling c5437ea429 Overhaul my earlier submission due to feedback. It's a large patch, but most of 
them are generic changes.

- Use the "fast" flag that's already being passed into the asm printers instead
  of shoving it into the DwarfWriter.

- Instead of calling "MI->getParent()->getParent()" for every MI, set the
  machine function when calling "runOnMachineFunction" in the asm printers.

Sanjiv Gupta c3f7b82628 Function temporaries can not overlap with retval or args.See the comment in source code to know the reason. Anything having .auto. in its name is local to a function in nature irrespective of the linkage specified. print static local variables in module level IDATA section.

Dale Johannesen 62fd95d6ec Get rid of the last non-DebugLoc versions of getNode! 
Many targets build placeholder nodes for special operands, e.g.
GlobalBaseReg on X86 and PPC for the PIC base.  There's no
sensible way to associate debug info with these.  I've left
them built with getNode calls with explicit DebugLoc::getUnknownLoc operands. 
I'm not too happy about this but don't see a good improvement;
I considered adding a getPseudoOperand or something, but it
seems to me that'll just make it harder to read.

 2009-02-07 00:55:49 +00:00
Dale Johannesen 84935759d5 Remove more non-DebugLoc getNode variants. Use 
getCALLSEQ_{END,START} to permit passing no DebugLoc
there.  UNDEF doesn't logically have DebugLoc; add
getUNDEF to encapsulate this.

Dale Johannesen 9f3f72f144 Get rid of one more non-DebugLoc getNode and 
its corresponding getTargetNode.  Lots of
caller changes.

Sanjiv Gupta 50aeb12d80 Made the common case of default address space directive as non-virtual for performance reasons. Provide a single virtual interface for directives of all sizes in non-default address spaces.

Sanjiv Gupta 964a29f671 Enable emitting of constant values in non-default address space as well. The APIs emitting constants now take an additional parameter signifying the address space in which to emit. The APIs like getData8BitsDirective() etc are made virtual enabling targets to be able to define appropirate directivers for various sizes and address spaces.

Dan Gohman 619ef48a52 Move a few containers out of ScheduleDAGInstrs::BuildSchedGraph 
and into the ScheduleDAGInstrs class, so that they don't get
destructed and re-constructed for each block. This fixes a
compile-time hot spot in the post-pass scheduler.

To help facilitate this, tidy and do some minor reorganization
in the scheduler constructor functions.

Duncan Sands 6ed40141f7 Change the interface to the type legalization method 
ReplaceNodeResults: rather than returning a node which
must have the same number of results as the original
node (which means mucking around with MERGE_VALUES,
and which is also easy to get wrong since SelectionDAG
folding may mean you don't get the node you expect),
return the results in a vector.
