26a84d4f3c Add support for CPU features (i.e., bugs) and workarounds. 
This is just the framework to identify the needed workarounds. They are not actually implemented.

63cc527fbc Inline assembly support for Blackfin. 
We use the same constraints as GCC, including those that are slightly insane for inline assembler.

d950941e13 Analog Devices Blackfin back-end. 
Generate code for the Blackfin family of DSPs from Analog Devices:

  http://www.analog.com/en/embedded-processing-dsp/blackfin/processors/index.html
  
We aim to be compatible with the exsisting GNU toolchain found at:

  http://blackfin.uclinux.org/gf/project/toolchain
  
The back-end is experimental.

4ea480499c Avoid forming a SELECT_CC in a type that the target doesn't 
support. This isn't immediately interesting, because Legalize
ends up lowering SELECT_CC if the target doesn't support it,
but this simplifies the process.

Also, if the SELECT_CC would be expanded in Legalize, it
can potentially end up with two copies of the condition
expression. By leaving it as SELECT+SETCC, the SELECT can be
expanded into two SELECTs that use a single SETCC.

The two comparisons are usually CSE'd, but depending on
when various expressions get legalized, the comparison
expression could involve calls to library functions, such
that the comparison expression may not be able to be CSE'd.
This will be needed by a future patch.

d90183d25d Move the getInlineAsmLength virtual method from TAI to TII, where 
the only real caller (GetFunctionSizeInBytes) uses it.

The custom ARM implementation of this is basically reimplementing
an assembler poorly for negligible gain.  It should be removed 
IMNSHO, but I'll leave that to ARMish folks to decide.

d5bbb07ec8 move getDwarfExceptionSection from TAI to TLOF and rename it to 
getLSDASection() to be more specific.  This makes it pretty obvious
that the ELF LSDA section is being specified wrong in PIC mode.  We're
probably getting a lot of startup-time relocations to a readonly page,
which is expensive and bad.

Someone who cares about ELF C++ should investigate this.

83d77faf6e Remove "JumpTableDataSection" from TAI, instead, have AsmPrinter 
compute it based on what it knows.  As part of this, rename getSectionForMergeableConstant
to getSectionForConstant because it works for non-mergable constants also.

The only functionality change from this is that Xcore will start dropping
its jump tables into readonly section instead of data section in -static mode.
This should be fine as the linker resolves the relocations.  If this is a
problem, let me know and we'll come up with another solution.
