from the perspective of LLVM exception handling. Otherwise the C++ personality
function may decide not to run them, if it only detects cleanup handlers.
 - Test case for this is exceptions.m in llvm-test.

elsewhere.  Very slightly decouples DeclSpec users from knowing the exact
diagnostics to report, and makes it easier to provide different diagnostics in
some places.

When LowerSubregsInstructionPass::LowerInsert eliminates an INSERT_SUBREG
instriction because it is an identity copy, make sure that the same registers
are alive before and after the elimination.

When the super-register is marked <undef> this requires inserting an
IMPLICIT_DEF instruction to make sure the super register is live.

Fix a related bug where a kill flag on the inserted sub-register was not transferred properly.

Finally, clear the undef flag in MachineInstr::addRegisterKilled. Undef implies dead and kill implies live, so they cant both be valid.

Thanks Chris.

appropriate.  Patch per report on llvmdev.  No testcase because the 
original report didn't come with a testcase, and I can't come up with a case
that actually fails.

This will cause it to enter the ".text" section instead of "_text"
but masm is already broken.

 - The theory is these should never actually be called, since these boil down to
   passes which can access the target data via the standard mechanism.

llvm_report_error already prints "LLVM ERROR:". So stop reporting errors like "LLVM ERROR: llvm: error:" or "LLVM ERROR: ERROR:".

llvm-svn: 77971

obviously correct.

Since we're generating stubs by hands we don't follow the ABI and don't
create a register spill area.
Don't use this area in compilation callback!

Fix a coaelescer bug. If a copy val# is extended to eliminate a non-trivially coalesced copy, and the copy kills its source register. Trim the source register's live range to the last use if possible. This fixes up kill marker to make the scavenger happy.
