but I cannot reproduce the problem and have scrubed my sources and

Formatting fixes. Mostly long lines and

This patch tackles the problem of parsing Mips
...
register names in the standalone assembler llvm-mc.
Registers such as $A1 can represent either a 32 or
64 bit register based on the instruction using it.
In addition, based on the abi, $T0 can represent different
32 bit registers.
The problem is resolved by the Mips specific AsmParser
td definitions changing to work together. Many cases of
RegisterClass parameters are now RegisterOperand.

Initial assembler implementation of Mips load address macro
...
This patch provides initial implementation of load address
macro instruction for Mips. We have implemented two kinds
of expansions with their variations depending on the size
of immediate operand:
1) load address with immediate value directly:
* la d,j => addiu d,$zero,j (for -32768 <= j <= 65535)
* la d,j => lui d,hi16(j)
ori d,d,lo16(j) (for any other 32 bit value of j)
2) load load address with register offset value
* la d,j(s) => addiu d,s,j (for -32768 <= j <= 65535)
* la d,j(s) => lui d,hi16(j) (for any other 32 bit value of j)
ori d,d,lo16(j)
addu d,d,s
This patch does not cover the case when the address is loaded
from the value of the label or function.

Implement methods that enable expansion of load immediate

macro instruction (li) in the assembler.
We have identified three possible expansions depending on
the size of immediate operand:
1) for 0 ≤ j ≤ 65535.
li d,j =>
ori d,$zero,j
2) for −32768 ≤ j < 0.
li d,j =>
addiu d,$zero,j
3) for any other value of j that is representable as a 32-bit integer.
li d,j =>
lui d,hi16(j)
ori d,d,lo16(j)
All of the above have been implemented in ths patch.
