into a new MCDirectives.h file.

to MCExpr then emit them through MCStreamer with EmitValue.  I think all
global variable initializers are now going through mcstreamer.

and some .weak directives.

cleanup and eliminate a bunch more uses of "EOL".

handle the comment better, MCize the non-.sleb case.

this makes the code work transparently the same

pretty printing encoding comments and eliminates redundancy on
the client side.  We now get pretty dwarf like this again:

        .byte   255                                         ## @LPStart Encoding = omit
        .byte   0                                           ## @TType Encoding = absptr
        .byte   0x28                                        ## @TType base offset
        .byte   3                                           ## Call site Encoding = udata4
        .byte   0x1a                                        ## Call site table size
...

llvm-svn: 94239

and much more accurately describes what it is all about.

output.  An example:

        .align  4, 0x90
LBB1_5:                                                     ## %while.cond3
                                                            ##   Parent Loop BB1_1 Depth=1
                                                            ## =>  This Loop Header: Depth=2
                                                            ##       Child Loop BB1_8 Depth 3
                                                            ##       Child Loop BB1_6 Depth 3

llvm-svn: 94225

For loop headers, print Inner loop along with the other stuff so it doesn't take
an extra line.  We now get stuff like this:

LBB1_4:                                                     ## %land.end
                                                            ##   in Loop: Header=BB1_1 Depth=1
        notb    %al
        testb   $1, %al
        jne     LBB1_8

and:

LBB1_6:                                                     ## %while.cond7
                                                            ## Inner Loop Header: Depth=3
                                                            ##     Inside Loop BB1_5 Depth 2
                                                            ##   Inside Loop BB1_1 Depth 1

which still isn't great for loop headers, but is much less verbose.

llvm-svn: 94221

comment emission stuff.  I'm going to rewrite this though because the
current output doesn't make sense.

llvm-svn: 94215

AddComment and GetCommentOS.  Add a blank line between globals
(even in non-verbose mode) to make the assembly more readable.

llvm-svn: 94202

that doesn't want to use twines.

llvm-svn: 94199

LoopStrengthReduce, as it's causing too much trouble (even with the
old LoopStrengthReduce code).

llvm-svn: 94172

Switch over the asm-verbose comment for double values to use it.  We now get:

_x:
	.long	343597384                                   ## double 1.231200e+02
	.long	1079953326

For example, note that the comment is on the same line as the .long.  Woo.

llvm-svn: 94166

llvm-svn: 94165

missing ones are libsupport, libsystem and libvmcore.  libvmcore is
currently blocked on bugpoint, which uses EH.  Once it stops using
EH, we can switch it off.

This #if 0's out 3 unit tests, because gtest requires RTTI information.
Suggestions welcome on how to fix this.

Teach pre-regalloc scheduler to schedule loads from nearby addresses. It may improve cache locality. This is controlled by -cluster-loads for now.

When XDEBUG is enabled, check for SelectionDAG cycles at some key
points.  This will help us find future problems like the one
described in PR6019.
