Caching it as a pointer allows us to reset it if the TargetMachine object
changes.

This also makes TableGen able to compute sizes/offsets of synthesized
indices representing tuples.

Fixes PR16146: gdb.base__call-ar-st.exp fails after
pre-RA-sched=source fixes.

Patch by Xiaoyi Guo!

This also fixes an unsupported dbg.value test case. Codegen was
previously incorrect but the test was passing by luck.

Change SelectionDAG::getXXXNode() interfaces as well as call sites of
these functions to pass in SDLoc instead of DebugLoc.

The wired physreg doesn't work on tied operands like on MOVXCC.

Add a README note to fix this later.

llvm-svn: 182225

llvm-svn: 182224

llvm-svn: 182222

Also clean up the arguments to all the MOVCC instructions so the
operands always are (true-val, false-val, cond-code).

[Sparc] Rearrange integer registers' allocation order so that register allocator will use I and G registers before using L and O registers.

Also, enable registers %g2-%g4 to be used in application and %g5 in 64 bit mode.

 This is to generate correct framesetup code when the function
 has variable sized allocas.

It was just a less powerful and more confusing version of
MCCFIInstruction. A side effect is that, since MCCFIInstruction uses
dwarf register numbers, calls to getDwarfRegNum are pushed out, which
should allow further simplifications.

I left the MachineModuleInfo::addFrameMove interface unchanged since
this patch was already fairly big.

Arguments after the fixed arguments never use the floating point
registers.

Don't ignore the high 32 bits of the immediate.

llvm-svn: 179985

With a little help from the frontend, it looks like the standard va_*
intrinsics can do the job.

Also clean up an old bitcast hack in LowerVAARG that dealt with
unaligned double loads. Load SDNodes can specify an alignment now.

Still missing: Calling varargs functions with float arguments.

For when 16 TB just isn't enough.

llvm-svn: 179474

This is the default model for non-PIC 64-bit code. It supports
text+data+bss linked anywhere in the low 16 TB of the address space.

llvm-svn: 179473

64-bit code models need multiple relocations that can't be inferred from
the opcode like they can in 32-bit code.

llvm-svn: 179472

Constant pool entries are accessed exactly the same way as global
variables.

llvm-svn: 179471

This fixes the pic32 code model for SPARC v9.

llvm-svn: 179469

SDNodes and MachineOperands get target flags representing the %hi() and
%lo() assembly annotations that eventually become relocations.

Also define flags to be used by the 64-bit code models.

llvm-svn: 179468

Currently, only abs32 and pic32 are implemented. Add a test case for
abs32 with 64-bit code. 64-bit PIC code is currently broken.
