few places in InstCombine to use it, to fix problems handling pointer
types. This fixes the recent llvm-gcc bootstrap error.

hey it uses .previous, so it should work :)

Re-apply LiveInterval index dumping patch, with fixes suggested by Bill
and others.

more step towards "semantics sections"

Add a testcase.

llvm-svn: 77992

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:".

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.

Add 'Indirect' LocInfo class and use to pass __m128 on win64. Also minore fixes here and there (mostly __m64).

Cleanup Darwin MMX calling conv stuff - make the stuff more generic. This also fixes a subtle bug, when 6th v1i64 argument passed wrongly.

Unbreak Win64 CC. Step one: honour register save area, fix some alignment and provide a different set of call-clobberred registers.

This is not just a matter of passing in the target triple from the module;
currently backends are making decisions based on the build and host
architecture. The goal is to migrate to making these decisions based off of the
triple (in conjunction with the feature string). Thus most clients pass in the
target triple, or the host triple if that is empty.

This has one important change in the way behavior of the JIT and llc.

For the JIT, it was previously selecting the Target based on the host
(naturally), but it was setting the target machine features based on the triple
from the module. Now it is setting the target machine features based on the
triple of the host.

For LLC, -march was previously only used to select the target, the target
machine features were initialized from the module's triple (which may have been
empty). Now the target triple is taken from the module, or the host's triple is
used if that is empty. Then the triple is adjusted to match -march.

The take away is that -march for llc is now used in conjunction with the host
triple to initialize the subtarget. If users want more deterministic behavior
from llc, they should use -mtriple, or set the triple in the input module.
