Chris Lattner d1acffc845 Change constantexpr global variable initializers to convert the constants
to MCExpr then emit them through MCStreamer with EmitValue.  I think all
global variable initializers are now going through mcstreamer.

Chris Lattner c3f23b84ea remove one form of EmitString, just use EmitBytes instead. We must
be careful to add a \0 at the end though, because EmitString didn't
do this.

Chris Lattner edf96a4cc3 add a new DwarfPrinter::EmitEncodingByte method which handles
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
...

Chris Lattner 00562558ab make the loop comment printer print out a much better structured
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

Chris Lattner e567c8e67f For blocks that are not loop headers, just print their loop depth and header BB.
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.

Chris Lattner 23e43dbba1 reenable the label loop comments and switch them to use the formatted
comment emission stuff.  I'm going to rewrite this though because the
current output doesn't make sense.

Chris Lattner a3eee3cb69 Convert some more random-comment-printing stuff to use
AddComment and GetCommentOS.  Add a blank line between globals
(even in non-verbose mode) to make the assembly more readable.

llvm-svn: 94202
2010-01-22 19:52:01 +00:00
Chris Lattner 8fa0e35f97 add a new MCAsmStreamer::GetCommentOS method to simplify stuff

llvm-svn: 94190
2010-01-22 18:21:35 +00:00
Chris Lattner 38e9219f71 Add the ability for MCStreamer to emit comments on the same line as directives.
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.

Chris Lattner 7ba0661f27 Stop building RTTI information for *most* llvm libraries. Notable
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.
