8a8d96b89c Revert some unneeded parts of the change in r107886 for the 
.weak_def_can_be_hidden directive.  Chris pointed out that the MCAsmInfo.h/.cpp
chunks aren't needed for this until the compiler starts generating these.  And
when that happens it will be more convenient for it to be a bool than a const
char*.

05a4c0b1f2 Introducing the "linker_weak" linkage type. This will be used for Objective-C 
metadata types which should be marked as "weak", but which the linker will
remove upon final linkage. For example, the "objc_msgSend_fixup_alloc" symbol is
defined like this:

       .globl l_objc_msgSend_fixup_alloc
       .weak_definition l_objc_msgSend_fixup_alloc
       .section __DATA, __objc_msgrefs, coalesced
       .align 3
l_objc_msgSend_fixup_alloc:
        .quad   _objc_msgSend_fixup
        .quad   L_OBJC_METH_VAR_NAME_1

This is different from the "linker_private" linkage type, because it can't have
the metadata defined with ".weak_definition".

dbea6d7acb "This is just a cosmetic change in MCAsmStreamer.cpp/EmitSymbolAttribute: all attributes have now a \t before and after, as done for '.type'. 
This makes the output look consistent, as well as help some third party assemblers expecting the attributes to be in the second column."

7e141838cd MC: Add dyn_cast support to MCSection.

80719b2d36 MC/Mach-O: Fix some differences in symbol flag handling. 
- Don't clear weak reference flag, 'as' was only "trying" to do this, it wasn't
   actually succeeding.
 - Clear the "lazy bound" bit when we mark something external. This corresponds
   roughly to the lazy clearing of the bit that 'as' implements in
   symbol_table_lookup.
 - The exact meaning of these flags appears pretty loose, since 'as' isn't very
   consistent. For now we just try to match 'as', we will clean this up one day
   hopefully.

8f5da3624f llvm-mc: Support reassignment of variables in one special case, when the

a81966a973 MC: Switch to using explicit MCAlignFragments with OnlyAlignAddress bit instead 
of manually doing padding/editing layout in LayoutSection().
    - This probably seems like six-of-one and half-dozen of another, but there
      is a method to my madness.

Daniel Dunbar
3fc379596a MC: Add MCAlignFragment::OnlyAlignAddress bit. This is a bit of magic that says the align fragment shouldn't contribute to the logical section size, it is will be used for cleaning up the code to handle section alignment. 
llvm-svn: 103690
 2010-05-13 01:10:26 +00:00
Daniel Dunbar
ec3a2ac5ed MC: Add MCSectionData::AddressSize, which is the size of the address space consumed by the section. This can differ from both the section logical size, and the section size on disk (although the current code handles this without making an explicit distinction).

9952bcf9f6 updated support for the COFF .linkonce 
Now, the .linkonce directive is emitted as part of MCSectionCOFF::PrintSwitchToSection instead of AsmPrinter::EmitLinkage since it is an attribute of the section the symbol was placed into not the symbol itself.

7670f69e42 MC/Mach-O x86_64: Switch to using fragment atom symbol.

 - This also fixes some correctness problems where local labels at the same
   address as non-local labels could be assigned to the wrong atom.
