format is not parsable, even if the module is legal. To get parsable output,
dump the module instead of the function or smaller, since metadata kind are
attached to the module (not the context).

(511*16) bytes register displacement (D-form).
NOTE: This is a potential headache, given the SPU's local core limitations,
allowing the software developer to commit stack overrun suicide unknowingly.
Also, large SPU stack frames will cause code size explosion. But, one presumes
that the software developer knows what they're doing...

GCC_except_table label but before the Lexception, which the FDE references.
This causes problems as the FDE does not point to the start of an LSDA chunk.
Use an unnormalized uleb128 for the call-site table length that includes the
padding.

- Function uses all scratch registers AND
- Function does not use any callee saved registers AND
- Stack size is too big to address with immediate offsets.
In this case a register must be scavenged to calculate the address of a stack
object, and the scavenger needs a spare register or emergency spill slot.

greater-than-or-equal SELECT_CCs to NEON vmin/vmax instructions. This is
only allowed when UnsafeFPMath is set or when at least one of the operands
is known to be nonzero.

the number of value bits, not the number of bits of allocation for in-memory
storage.
Make getTypeStoreSize and getTypeAllocSize work consistently for arrays and
vectors.
Fix several places in CodeGen which compute offsets into in-memory vectors
to use TargetData information.
This fixes PR1784.

Adding the function "lookupGCCName" to the MBlazeIntrinsicInfo
class to support the Clang MicroBlaze target.
Additionally, minor fixes which remove some unused PIC code
(PIC is not supported yet in the MicroBlaze backend) and
removed some unused variables.

movechild/record -> recordchild/movechild and
movechild/moveparent -> noop xforms. This slightly shrinks the tables
(x86 to 117454) and enables adding future improvements.

the old one around for comparative purposes: have the
ENABLE_NEW_ISEL #define (which is not enabled on mainline) stop
emitting the old isel at all, yay for build time win.

the new isel: fold movechild+record+moveparent into a
single recordchild N node. This shrinks the X86 table
from 125443 to 117502 bytes.

necessary to swap the operands to handle NaN and negative zero properly.
Also, reintroduce logic for checking for NaN conditions when forming
SSE min and max instructions, fixed to take into consideration NaNs and
negative zeros. This allows forming min and max instructions in more
cases.

to adding them in a determinstic order (bottom up from
the root) based on the structure of the graph itself.
This updates tests for some random changes, interesting
bits: CodeGen/Blackfin/promote-logic.ll no longer crashes.
I have no idea why, but that's good right?
CodeGen/X86/2009-07-16-LoadFoldingBug.ll also fails, but
now compiles to have one fewer constant pool entry, making
the expected load that was being folded disappear. Since it
is an unreduced mass of gnast, I just removed it.
This fixes PR6370

internal nodes with flag results. Record these with a new
OPC_MarkFlagResults opcode and use this to update the interior
nodes' flag results properly. This fixes CodeGen/X86/i256-add.ll
with the new isel.
