Big change #1 for personality function references:
Eliminate the PersonalityPrefix/Suffix & NeedsIndirectEncoding
fields from MAI: they aren't part of the asm syntax, they are
related to the structure of the object file.

To replace their functionality, add a new
TLOF::getSymbolForDwarfGlobalReference method which asks targets
to decide how to reference a global from EH in a pc-relative way.

The default implementation just returns the symbol.  The default
darwin implementation references the symbol through an indirect
$non_lazy_ptr stub.  The bizarro x86-64 darwin specialization
handles the weird "foo@GOTPCREL+4" hack.

DwarfException.cpp now uses this to emit the reference to the
symbol in the right way, and this also eliminates another
horrible hack from DwarfException.cpp:

-    if (strcmp(MAI->getPersonalitySuffix(), "+4@GOTPCREL"))

15 years agoWhen a constant's type is refined, update the constant in place
Dan Gohman [Tue, 15 Sep 2009 15:58:07 +0000 (15:58 +0000)]
When a constant's type is refined, update the constant in place
instead of cloning and RAUWing it.

 - Make AbstractTypeUser a friend of Value so that it can offer
   its subclasses a way to update a Value's type in place. This
   is better than a universally visible setType method on Value,
   and it's sufficient for the immediate need.

 - Eliminate the constant "convert" functions. This eliminates a
   lot of logic duplication, and fixes a complicated bug where a
   constant can't actually be cloned during the type refinement
   process because some of the types that its folder needs are
   half-destroyed, being in the middle of refinement themselves.

 - Move the getValType functions from being static overloaded
   functions in Constants.cpp to be members of class template
   specializations in ConstantsContext.h. This means that the
   code ends up getting instantiated twice, however it also
   makes it possible to eliminate all "convert" functions, so
   it's not a big net code size increase. And if desired, the
   duplicate instantiations could be eliminated with some
