Colin LeMahieu ecef1d9cbc [Hexagon] Adding relocation for code size, cold path optimization allowing a 23-bit 4-byte aligned relocation to be a valid instruction encoding.
The usual way to get a 32-bit relocation is to use a constant extender which doubles the size of the instruction, 4 bytes to 8 bytes.

Another way is to put a .word32 and mix code and data within a function.  The disadvantage is it's not a valid instruction encoding and jumping over it causes prefetch stalls inside the hardware.

This relocation packs a 23-bit value in to an "r0 = add(rX, #a)" instruction by overwriting the source register bits.  Since r0 is the return value register, if this instruction is placed after a function call which return void, r0 will be filled with an undefined value, the prefetch won't be confused, and the callee can access the constant value by way of the link register.

Dimitry Andric 227b928abc Fix several accidental DOS line endings in source files
Summary:
There are a number of files in the tree which have been accidentally checked in with DOS line endings.  Convert these to native line endings.

There are also a few files which have DOS line endings on purpose, and I have set the svn:eol-style property to 'CRLF' on those.
