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."

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).

Fix (and test) function-local metadata that occurs before the instruction that it refers to; fix is to not enumerate operands of function-local metadata until after all instructions have been enumerated

least we avoid cases where we might crash because of an assertion
failure later on (when the return type differs from what is expected).

Don't try to fold DeclRefExprs that point to ParmVarDecls. This had the side-effect of always folding the expression to the default argument of the parameter. For example:

void f(int a = 10) {
  return a;
}

would always return 10, regardless of the passed in argument.

This fixes another 600 test failures. We're now down to only 137 failures!

In some contexts, type declarations cannot occur. Pass this information down to ParseClassSpecifier, to make its decision easier. Fixes PR6200.

doing so invalidates the file guard optimization and is not
in the spirit of "#if 0" because it is supposed to completely
skip everything, even if it isn't lexically valid. Patch by
Abramo Bagnara!

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.
