Bill Wendling 374d7f2b16 If we have a function with an unreachable statement such that the ending debug
information is in an unreachable block, then it's possible that the high/low pc
values won't be set for the dwarf information. E.g., this function:

void abort(void) __attribute__((__noreturn__));
void dead_beef(void) __attribute__ ((noreturn));

int *b;

void dead_beef(void) {
  *b=0xdeadbeef;
  abort();
}

has a call to "@llvm.dbg.region.end" only in the unreachable block:

define void @dead_beef() noreturn nounwind  {
entry:
	call void @llvm.dbg.func.start(...)
	call void @llvm.dbg.stoppoint(...)
...
	call void @abort( ) noreturn nounwind 
	unreachable

return:		; No predecessors!
	call void @llvm.dbg.stoppoint(...)
	call void @llvm.dbg.region.end(...)
	ret void
}

The dwarf information emitted is something like:

0x00000084:     TAG_subprogram [5]  
                 AT_name( "dead_beef" )
                 AT_external( 0x01 )
                 AT_prototyped( 0x01 )
                 AT_decl_file( 0x01 )
                 AT_decl_line( 0x08 )

Note that this is *not* the best fix for this problem, but a band-aid for an
gaping wound. This code needs to be changed when we revamp our debugging
information.

s/ParamAttr/Attribute/g
s/PAList/AttrList/g
s/FnAttributeWithIndex/AttributeWithIndex/g
s/FnAttr/Attribute/g

This sets the stage 
- to implement function notes as function attributes and 
- to distinguish between function attributes and return value attributes.

Devang Patel 4c758ea3e0 Large mechanical patch.
s/ParamAttr/Attribute/g
s/PAList/AttrList/g
s/FnAttributeWithIndex/AttributeWithIndex/g
s/FnAttr/Attribute/g

This sets the stage 
- to implement function notes as function attributes and 
- to distinguish between function attributes and return value attributes.

This requires corresponding changes in llvm-gcc and clang.
