Constants and Metadata share ValueList. This means they must be emitted interleaved (using appropriate BLOCK_IDs) otherwise ValuePtrs index gets out of sync.

Remove ARM specific getInlineAsmLength. We'll rely on the simpler (and faster) generic algorithm for now. If more accurate computation is needed, we'll rely on the disassembler.

Emit sub r, #c instead of transforming it to add r, #-c if c fits in 8-bit. This is a bit of pre-mature optimization. 8-bit variant makes it likely it will be narrowed to a 16-bit instruction.

TLI.computeMaskedBitsForTargetNode from ComputeMaskedBits, since
the former may call back into the latter. This fixes a major
compile time problem on a testcase that happnened to hit this
in a particularly bad way, PR4643.

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

llvm-svn: 78005

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

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

llvm-svn: 78003

more step towards "semantics sections"

llvm-svn: 78002

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:".

llvm-svn: 77971

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!
