df1b7b6164 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.

1d3b05933f make mcasmstreamer handle expanding 8 byte integer constants to 
4-byte constants if .quad isn't supported.  Switch a bunch of

7c3ff46d45 add an MCAsmStreamer::EmitFill specialization of EmitFill that 
emits one directive instead of N.  Not doing this would be a
significant regression on the # bytes generated by .fill.

6f360c3c91 now that MCSymbol::print doesn't use it's MAI argument, we can 
remove it and change all the code that prints MCSymbols to use 
<< instead, which is much simpler and cleaner.

4a33f01892 Change MCAsmStreamer to take an MCInstPrinter instead of a 
full AsmPrinter, and change TargetRegistry to keep track
of registered MCInstPrinters.

llvm-mc is still linking in the entire
target foo to get the code emitter stuff, but this is an
important step in the right direction.

2bb8df3b5d llvm-mc: Clean up some handling of symbol/section association to be more correct 
(external was really undefined and there wasn't an explicit representation for
absolute symbols).
 - This still needs some cleanup to how the absolute "pseudo" section is dealt
   with, but I haven't figured out the nicest approach yet.

b82fc63e02 Make AsmStreamer maintain a notion of the current section, pushing it up from the 
MCAsmStreamer.  Based on this, eliminate the current section from AsmPrinter.

While I'm at it, clean up the last of the horrible "switch to null section" stuff
and add an assert.  This change is in preparation for completely eliminating 
asmprinter::switchtosection.

fc68e5368b change AsmPrinter to switch sections using AsmStreamer instead of 
doing it directly.  This requires const'izing a bunch of stuff that
took sections, but this seems like the right semantic thing to do:
emitting a label to a section shouldn't mutate the MCSection object
itself, for example.

3c9ab92a24 llvm-mc: Fix bugs where bytes were unintentionally being printed as signed. 
- We now print all of 403.gcc cleanly (llvm-mc -> 'as' as diffed to 'as'), minus two 
   'rep;movsl' instructions (which I missed before).

b9d9ce9513 llvm-mc: When handling a .set, make sure to print subsequent references to the 
symbol as the symbol name itself, not the expression it was defined to. These
have different semantics due to the quirky .set behavior (which absolutizes an
expression that would otherwise be treated as a relocation).

dc5840c57c Update llvm-mc / MCAsmStreamer to print the instruction using the actual target 
specific printer (this only works on x86, for now).
 - This makes it possible to do some correctness checking of the parsing and
   matching, since we can compare the results of 'as' on the original input, to
   those of 'as' on the output from llvm-mc.

 - In theory, we could now have an easy ATT -> Intel syntax converter. :)

 2009-08-10 18:15:01 +00:00
Chris Lattner
cc70d578be Make the big switch: Change MCSectionMachO to represent a section *semantically* 
instead of syntactically as a string.  This means that it keeps track of the 
segment, section, flags, etc directly and asmprints them in the right format.
This also includes parsing and validation support for llvm-mc and 
"attribute(section)", so we should now start getting errors about invalid 
section attributes from the compiler instead of the assembler on darwin.

Still todo: 
1) Uniquing of darwin mcsections
2) Move all the Darwin stuff out to MCSectionMachO.[cpp|h]
3) there are a few FIXMEs, for example what is the syntax to get the
   S_GB_ZEROFILL segment type?
