2010-01-15 23:25:11 +00:00
Chris Lattner 91687f6e28 add a AsmPrinter::GetGlobalValueSymbol and GetExternalSymbolSymbol
helper method, use it to simplify some code.

Chris Lattner 25d8ed3773 remove uses of deprecated functions, this generates slightly
different BlockAddress labels, but nothing semantically important.

Add a FIXME that BlockAddress codegen is broken if the LLVM BB has 
an empty name (e.g. strip was run).

Chris Lattner 2b630fe822 use the new form of getNameWithPrefix, not makeNameProper.
Among other things, this would do very weird things if the 
basic block name had (e.g.) a space in it on darwin:
makeNameProper would add quotes, then the mcsymbol would 
escape the quotes.

Chris Lattner 209aecad0c change Mangler::makeNameProper to return its result in a SmallVector
instead of returning it in an std::string.  Based on this change:

1. Change TargetLoweringObjectFileCOFF::getCOFFSection to take a StringRef
2. Change a bunch of targets to call makeNameProper with a smallstring,
   making several of them *much* more efficient.
3. Rewrite Mangler::makeNameProper to not build names and then prepend
   prefixes, not use temporary std::strings, and to avoid other crimes.

Dan Gohman 3a6164e8ab Print newlines after printing labels for debug info, so that the output
isn't cluttered with things like "Llabel47:Llabel48:  movq  (%rsi), %xmm3"

Dan Gohman abc77742c8 Fix this code to use DIScope instead of DICompileUnit, as in r90181.
Don't print "SrcLine"; just print the filename and line number, which
is obvious enough and more informative.

David Greene 25905c8336 Support spill comments.
Have the asm printer emit a comment if an instruction is a spill or
reload and have the spiller mark copies it introdues so the asm printer
can also annotate those.

David Greene 659c1a9d78 Move DebugInfo checks into EmitComments and remove them from

Jakob Stoklund Olesen c7cfc94bcc Print out an informative comment for KILL instructions.
The KILL pseudo-instruction may survive to the asm printer pass, just like the IMPLICIT_DEF. Print the KILL as a comment instead of just leaving a blank line in the output.

With -asm-verbose=0, a blank line is printed, like IMPLICIT?DEF.

Dan Gohman 10d3dc569b Instead of printing unnecessary basic block labels as labels in
verbose-asm mode, print comments instead. This eliminates a non-comment
difference between verbose-asm mode and non-verbose-asm mode.

Also, factor out the relevant code out of all the targets and into
target-independent code.

Chris Lattner fdd8790718 strength reduce a ton of type equality tests to check the typeid (Through
the new predicates I added) instead of going through a context and doing a
pointer comparison.  Besides being cheaper, this allows a smart compiler
to turn the if sequence into a switch.

Bob Wilson b633d7a665 Add a new virtual EmitStartOfAsmFile method to the AsmPrinter and use this
to emit target-specific things at the beginning of the asm output.  This
fixes a problem for PPC, where the text sections are not being kept together
as expected.  The base class doInitialization code calls DW->BeginModule()
which emits a bunch of DWARF section directives.  The PPC doInitialization
code then emits all the TEXT section directives, with the intention that they
will be kept together. But as I understand it, the Darwin assembler treats
the default TEXT section as a special case and moves it to the beginning of
the file, which means that all those DWARF sections are in the middle of
the text.  With this change, the EmitStartOfAsmFile hook is called before
the DWARF section directives are emitted, so that all the PPC text section
directives come out right at the beginning of the file.

Anton Korobeynikov 592638ae05 Allow symbols to start from the digit if target requests it. This allows, e.g. pinning
