following it. However, the EmitGlobalConstant method wasn't emitting a body for
the constant. The assembler doesn't like that. Before, we were generating this:

  .zerofill __DATA, __common, __cmd, 1, 3

This fix puts us back to that semantic.

short-circuited conditions to AND/OR expressions, and those expressions
are often converted back to a short-circuited form in code gen.  The
original source order may have been optimized to take advantage of the
expected values, and if we reassociate them, we change the order and
subvert that optimization.  Radar 7497329.

Instruction selection for X86 now can choose an instruction
sequence that will fit any address of any symbol, no matter
the pointer width. X86-64 uses a mov+call-via-reg sequence
for this.

This makes the inliner about as agressive as it was before my changes to the
inliner cost calculations. These levels give the same performance and slightly
smaller code than before.

ProcessImplicitDefs would only mark one operand per instruction with <undef>.

64-bit sparc codegen.  Patch by Nathan Keynes!

llvm-svn: 95293

"Attached patch removes the extra NUL bytes from the output and changes
test/Archive/MacOSX.toc from a binary to a text file (removes
svn:mime-type=application/octet-stream and adds svn:eol-style=native).  I can't
figure out how to get SVN to include the new contents of the file in the patch
so I'm attaching it separately."

Patch by James Abbatiello!

Fix bugs where we would compute out of bounds as in bounds, and where
we couldn't know that the linker could override the size of an array.

Add a few new testcases, change existing testcase to use a private
global array instead of extern.

It's too risky to eliminate sext / zext of call results for tail call optimization even if the caller / callee attributes completely match. The callee may have been bitcast'ed (or otherwise lied about what it's doing).

than int. This will make it more convenient for LSR, which does
a lot of things with int64_t offsets.

llvm-svn: 95281

Indirect tail call has to go through a call preserved register since it's after callee register pops. X86 isel lowering is using EAX / R11 and it was somehow adding that to function live out. That prevented the real function return register from being added to the function live out list and bad things happen.
This fixes 483.xalancbmk (with tail call opt).

Lock prefix, Repeat string operation prefixes and the Segment override prefixes.
Also added versions of the move string and store string instructions without the
repeat prefixes to X86InstrInfo.td. And finally marked the rep versions of
move/store string records in X86InstrInfo.td as isCodeGenOnly = 1 so tblgen is
happy building the disassembler files.
