9cfc799171 Remove another duplicated variable. We only need one to tell us if the linker
knows dwarf or not.

4db98becf7 The inline asm operand modifier 'n' is suppose
to be generic across architectures. It has the
following description in the gnu sources:

    Negate the immediate constant

Several Architectures such as x86 have local implementations
of operand modifier 'n' which go beyond the above description
slightly. This won't affect them.

Affected files:

    lib/CodeGen/AsmPrinter/AsmPrinterInlineAsm.cpp
        Added 'n' to the switch cases.

    test/CodeGen/Generic/asm-large-immediate.ll
        Generic compiled test (x86 for me)

    test/CodeGen/Mips/asm-large-immediate.ll
        Mips compiled version of the generic one

d5e11ad51a The inline asm operand modifier 'c' is suppose
to be generic across architectures. It has the
following description in the gnu sources:

    Substitute immediate value without immediate syntax

Several Architectures such as x86 have local implementations
of operand modifier 'c' which go beyond the above description
slightly. To make use of the generic modifiers without overriding
local implementation one can make a call to the base class method
for AsmPrinter::PrintAsmOperand() in the locally derived method's 
"default" case in the switch statement. That way if it is already
defined locally the generic version will never get called.

This change is needed when test/CodeGen/generic/asm-large-immediate.ll
failed on a native Mips board. The test was assuming a generic
implementation was in place.

Affected files:

    lib/Target/Mips/MipsAsmPrinter.cpp:
        Changed the default case to call the base method.
    lib/CodeGen/AsmPrinter/AsmPrinterInlineAsm.cpp
        Added 'c' to the switch cases.
    test/CodeGen/Mips/asm-large-immediate.ll
        Mips compiled version of the generic one

396618b43a Switch all register list clients to the new MC*Iterator interface.
No functional change intended.

Sorry for the churn. The iterator classes are supposed to help avoid
giant commits like this one in the future. The TableGen-produced
register lists are getting quite large, and it may be necessary to
change the table representation.

This makes it possible to do so without changing all clients (again).

3e96531186 Refactor data-in-code annotations.
Use a dedicated MachO load command to annotate data-in-code regions.
This is the same format the linker produces for final executable images,
allowing consistency of representation and use of introspection tools
for both object and executable files.

Data-in-code regions are annotated via ".data_region"/".end_data_region"
directive pairs, with an optional region type.

data_region_directive := ".data_region" { region_type }
region_type := "jt8" | "jt16" | "jt32" | "jta32"
end_data_region_directive := ".end_data_region"

The previous handling of ARM-style "$d.*" labels was broken and has
been removed. Specifically, it didn't handle ARM vs. Thumb mode when
marking the end of the section.

21e42d0ea5 It's possible to have a constant expression who's size is quite big (e.g.,
i128). In that case, we may not be able to print out the MCExpr as an
expression. For instance, we could have an MCExpr like this:

    0xBEEF0000BEEF0000 | (0xBEEF0000BEEF0000 << 64)

The MCExpr printer handles sizes up to 64-bits, but this expression would
require 128-bits. In this situation, try to evaluate the constant expression and
emit that as the value into 64-bit chunks.

d55a2664f9 Allow the use of an alternate symbol for calculating a function's size.
The standard function epilog includes a .size directive, but ppc64 uses
an alternate local symbol to tag the actual start of each function.

Until recently, binutils accepted the .size directive as:
 .size	test1, .Ltmp0-test1
however, using this directive with recent binutils will result in the error:
 .size expression for XXX does not evaluate to a constant
so we must use the label which actually tags the start of the function.
