For mips a branch an 18-bit signed offset (the 16-bit
offset field shifted left 2 bits) is added to the
address of the instruction following the branch
(not the branch itself), in the branch delay slot,
to form a PC-relative effective target address.
Previously, the code generator did not perform the
shift of the immediate branch offset which resulted
in wrong instruction opcode. This patch fixes the issue.

This patch that enables the Mips assembler to use symbols for offset for instructions2013-03-22T00:05:30ZJack Carterjack.carter@imgtec.com2013-03-22T00:05:30Zurn:sha1:25df6a93f3324bd30f44dcb95fd17aff0a92d438
This patch uses the generated instruction info tables to
identify memory/load store instructions.
After successful matching and based on the operand type
and size, it generates additional instructions to the output.

This patch enables the Mips .set directive to define aliases2013-03-21T21:44:16ZJack Carterjack.carter@imgtec.com2013-03-21T21:44:16Zurn:sha1:c91b5e197bb41ccb2f9f78b6176e61c848df9e15
The .set directive in the Mips the assembler can be
used to set the value of a symbol to an expression.
This changes the symbol's value and type to conform
to the expression's.
Syntax: .set symbol, expression
This patch implements the parsing of the above syntax
and enables the parser to use defined symbols when
parsing operands.

Add a new method which enables one to change register classes.2013-03-14T22:02:09ZReed Kotlerrkotler@mips.com2013-03-14T22:02:09Zurn:sha1:f8b0a08b6a2e2f4eacdb05eae9a8dd704b692b55
See the Mips16ISetLowering.cpp patch to see a use of this.
For now now the extra code in Mips16ISetLowering.cpp is a nop but is
used for test purposes. Mips32 registers are setup and then removed and
then the Mips16 registers are setup.
Normally you need to add register classes and then call
computeRegisterProperties.

Provide the register scavenger to processFunctionBeforeFrameFinalized2013-03-14T20:33:40ZHal Finkelhfinkel@anl.gov2013-03-14T20:33:40Zurn:sha1:3080d23fde4981835d8a7faf46c152441fadb11f
Add the current PEI register scavenger as a parameter to the
processFunctionBeforeFrameFinalized callback.
This change is necessary in order to allow the PowerPC target code to
set the register scavenger frame index after the save-area offset
adjustments performed by processFunctionBeforeFrameFinalized. Only
after these adjustments have been made is it possible to estimate
the size of the stack frame.
