No new tests are added.
All tests in ExecutionEngine/MCJIT that have been failing pass after this patch
is applied (when "make check" is done on a mips board).

floats.

Refactor the TableGen'erated fixed length disassemblmer to use a
table-driven state machine rather than a massive set of nested
switch() statements.

As a result, the ARM Disassembler (ARMDisassembler.cpp) builds much more
quickly and generates a smaller end result. For a Release+Asserts build on
a 16GB 3.4GHz i7 iMac w/ SSD:

Time to compile at -O2 (averaged w/ hot caches):
  Previous: 35.5s
  New:       8.9s

TEXT size:
  Previous: 447,251
  New:      297,661

Builds in 25% of the time previously required and generates code 66% of
the size.

Execution time of the disassembler is only slightly slower (7% disassembling
10 million ARM instructions, 19.6s vs 21.0s). The new implementation has
not yet been tuned, however, so the performance should almost certainly
be recoverable should it become a concern.

The fields in the td definition were switched.

llvm-svn: 161607

initialize fields of the class that it used.

The result was nonsense code.

Before:
0000000000000000 <foo>:
   0:    00441100     0x441100
   4:    03e00008     jr    ra
   8:    00000000     nop

After:
0000000000000000 <foo>:
   0:    00041000     sll    v0,a0,0x0
   4:    03e00008     jr    ra
   8:    00000000     nop

I hit this in a very large program (spirit.cpp), but 
have not figured out how to make a small make check
test for it.

llvm-svn: 161366

were using a class defined for 32 bit instructions and 
thus the instruction was for addiu instead of daddiu.

This was corrected by adding the instruction opcode as a 
field in the  base class to be filled in by the defs.

llvm-svn: 161359

These 2 relocations gain access to the 
highest and the second highest 16 bits
of a 64 bit object.

R_MIPS_HIGHER %higher(A+S)
The %higher(x) function is [ (((long long) x + 0x80008000LL) >> 32) & 0xffff ]. 

R_MIPS_HIGHEST %highest(A+S)
The %highest(x) function is [ (((long long) x + 0x800080008000LL) >> 48) & 0xffff ]. 

llvm-svn: 161348

Change these to patterns.
2. Add another 16 instructions.

call when the function does not have a reserved call frame.

llvm-svn: 161092

MipsSEFrameLowering.

Implement MipsSEFrameLowering::hasReservedCallFrame. Call frames will not be
reserved if there is a call with a large call frame or there are variable sized
objects on the stack.

The frame object which points to the dynamically allocated area will not be
needed after changes are made to cease reserving call frames.

or not it is in mips16 mode. Define MipsPseudo (mode-independant pseudo) and
PseudoSE (mips32/64 pseudo) classes.

llvm-svn: 161069

arguments to the stack in MipsISelLowering::LowerCall, use stack pointer and
integer offset operands rather than frame object operands.

llvm-svn: 161068

single-precision load and store.

Also avoid selecting LUXC1 and SUXC1 instructions during isel. It is incorrect
to map unaligned floating point load/store nodes to these instructions.

llvm-svn: 161063

replace uses of function getMaxCallFrameSize defined in MipsFunctionInfo with
the one MachineFrameInfo has.

llvm-svn: 160774

 
The long branch pass (fixed in r160601) no longer uses the global base register
to compute addresses of branch destinations, so it is not necessary to reserve
a slot on the stack.

Hello world will compile and execute with this patch.

Patch by Reed Kotler.

llvm-svn: 160651

llvm-svn: 160636

This pass no longer requires that the global pointer value be saved to the
stack or register since it uses bal instruction to compute branch distance.

llvm-svn: 160601

llvm-svn: 160599

llvm-svn: 160598

Test case will be added later when long branch patch is checked in.
