 This patch introduces RegisterOperand class into Mips FPU instruction definitions and adds dedicated parser methods to MipsAsmParser. It is the first in a series of patches that should fix the problems with parsing Mips FPU instructions and optimize the code in MipsAsmParser.

Access the TargetLoweringInfo from the TargetMachine object instead of caching it. The TLI may change between functions. No functionality change.

llvm-svn: 184360

The RenderMethod field in RegisterOperand class sets the name of the method on the target specific operand to call to add the target specific operand to an MCInst. This patch defines RenderMethod for mips RegisterOperand classes and removes redundant code from MipsAsmParser.cpp

When producing objects that are abi compliant we are 
marking neither the object file nor the assembly file
correctly and thus generate warnings. 

We need to set the EF_CPIC flag in the ELF header when
generating direct object.

Note that the warning is only generated when compiling without PIC.

When compiling with clang the warning will be suppressed by supplying:

 -Wa,-mno-shared -Wa,-call_nonpic

Also the following directive should also be added:

	.option	pic0

when compiling without PIC,  This eliminates the need for supplying:

  -mno-shared -call_nonpic

on the assembler command line.

Someone may want to do something crazy, like replace these objects if they
change or something.

No functionality change intended.

Frame index handling is now target-agnostic, so delete the target hooks
for creation & asm printing of target-specific addressing in DBG_VALUEs
and any related functions.

Backends shouldn't retain any global state. No functionality change.

The pass emits a call to sqrt that has attribute "read-none". This call will be
converted to an ISD::FSQRT node during DAG construction, which will turn into
a mips native sqrt instruction.

or unsigned arguments and I did not distinguish the case and improperly
rejected some valid cases that the assembler had previously accepted
when they were pure pseudos that expanded as assembly instructions.

the internals of TargetMachine could change.

Caching it as a pointer allows us to reset it if the TargetMachine object

Fixes PR16146: gdb.base__call-ar-st.exp fails after
pre-RA-sched=source fixes.

Patch by Xiaoyi Guo!

This also fixes an unsupported dbg.value test case. Codegen was
previously incorrect but the test was passing by luck.

llvm-svn: 182885

This patch solves the problem of numeric register values not being accepted:

../set_alias.s:1:11: error: expected valid expression after comma
        .set    r4,$4
                    ^
The parsing of .set directive is changed and handling of symbols in code 
as well to enable this feature. 

The test example is added.

There was exactly one caller using this API right, the others were relying on
specific behavior of the default implementation. Since it's too hard to use it
right just remove it and standardize on the default behavior.

pic calls. These need to be there so we don't try and use helper
functions when we call those.

As part of this, make sure that we properly exclude helper functions in pic
mode when indirect calls are involved.

By default, a teq instruction is inserted after integer divide. No divide-by-zero

Previously, three instructions were needed:

trunc.w.s $f0, $f2
mfc1 $4, $f0
sw $4, 0($2)

Now we need only two:

trunc.w.s $f0, $f2
swc1 $f0, 0($2)
