7e998b7363 add some fixme's for MCizing. EH still has a few things that 
need to be MCized, but the last debug info thing are LEB and
cygwin specific (which the MC api doesn't support yet) and
one specific form of EmitReference which I'll tackle next.

566cae9086 eliminate EOL, adding all comments with the OutStreamer.AddComment 
method.  With this, comments should end up on the same lines as the .byte
directives (for example) and we now get no output with:

$ llc CodeGen/X86/2009-02-12-DebugInfoVLA.ll -o - -filetype=null -asm-verbose

woot.

1b6d60d1c0 convert the non-"ispcrel" case of EmitReference to MC, 
significant debug info testcases are now all going through
MCStreamer, though they print a lot of extraneous newlines to "O".

c3b70f636f strength reduce MMI::MappedLabel to MMI::isLabelDeleted, 
and add a FIXME about how we are eventually going to zap this
lookup table once mc world domination is complete.

the one special case into EmitSectionOffset.  MCize
the non-special case in EmitSectionOffset.

27a9732450 simplify EmitSectionOffset to always use .set if it is 
available, the only thing this affects is that we produce
.set in one case we didn't before, which shouldn't harm
anything.  Make EmitSectionOffset call EmitDifference
instead of duplicating it.

98aa245070 MC'ize padding when padding the ULEB128 value. 
llvm-svn: 97087
 2010-02-25 00:24:52 +00:00
Bill Wendling
88fdcd323d LLVM puts padding bytes in the __gcc_except_tab section after the 
GCC_except_table label but before the Lexception, which the FDE references.
This causes problems as the FDE does not point to the start of an LSDA chunk.

Use an unnormalized uleb128 for the call-site table length that includes the
padding.

ff234e09b9 Eliminate SetDirective, and replace it with HasSetDirective. 
Default HasSetDirective to true, since most targets have it.

The targets that claim to not have it probably do, or it is
spelled differently. These include Blackfin, Mips, Alpha, and
PIC16.  All of these except pic16 are normal ELF targets, so
they almost certainly have it.

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

8b5d55ed06 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.

20eac92d88 Clean up LSDA name generation and use for SJLJ exception handling. This 
makes an eggregious hack somewhat more palatable. Bringing the LSDA forward
and making it a GV available for reference would be even better, but is
beyond the scope of what I'm looking to solve at this point.

Objective C++ code could generate function names that broke the previous
scheme. This fixes that.

fbcc663cbf llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable. 
This adds location info for all llvm_unreachable calls (which is a macro now) in
!NDEBUG builds.
In NDEBUG builds location info and the message is off (it only prints
"UREACHABLE executed").

56d0659726 assert(0) -> LLVM_UNREACHABLE. 
Make llvm_unreachable take an optional string, thus moving the cerr<< out of
line.
LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for
NDEBUG builds.

47054f3d57 Split out the Dwarf writer stuff into separate files. This is a much more 
logical/sane approach to organizing all of the stuff that goes into writing out
DWARF information. Honestly? even this is too complex for what it's supposed to
be doing.

Trivia: It *looks* like there would be functionality changes, however there aren't!
