John McCall 077dc60540 Don't assert on attempts to throw 'bool'. I wonder if in the history of C++ 
anyone has ever intentionally done this outside of a compiler test case.

John McCall 4af6bf1fdc Apply visibility in IR gen to variables that are merely declared 
and never defined.  We were previously emitting these with default
visibility unless they were declared with private_extern.

Ignore global visibility settings when computing visibility for
a declaration's context, and key several conditions on whether a
visibility attribute exists anywhere in the hierarchy as opposed
to whether it exists at the current level.

Greg Clayton 93aa84e83b Modified the lldb_private::TypeList to use a std::multimap for quicker lookup 
by type ID (the most common type of type lookup).

Changed the API logging a bit to always show the objects in the OBJECT(POINTER)
format so it will be easy to locate all instances of an object or references
to it when looking at logs.

Charles Davis 31575f758c Add a hook to the CXXABI object to get the default method calling convention. 
This isn't used yet, because someone more experienced than I needs to look
at the type system about gutting getCanonicalCallConv().

NAKAMURA Takumi 821de3d161 test/Scripts/macho-dump: Make hack for Python-2.4. [PR7995] 
With Python-2.4, Reader::read64 always returns (unexpected) long integer.
FileCheck detects failure on test/MC/MachO among '0' and '0L'.

CentOS5(aka RHEL5 clone) provides python-2.4.

John McCall 033caa5895 When computing the visibility of a class member, calculate the visibility 
of its context without considering global settings like -fvisibility=hidden.

Sean Callanan 322f529b37 Added a user-settable variable, 'target.expr-prefix', 
which holds the name of a file whose contents are
prefixed to each expression.  For example, if the file
~/lldb.prefix.header contains:

typedef unsigned short my_type;

then you can do this:

(lldb) settings set target.expr-prefix '~/lldb.prefix.header'
(lldb) expr sizeof(my_type)
(unsigned long) $0 = 2

When the variable is changed, the corresponding file
is loaded and its contents are fetched into a string
that is stored along with the target.  This string
is then passed to each expression and inserted into
it during parsing, like this:

typedef unsigned short my_type;
                             
void                           
$__lldb_expr(void *$__lldb_arg)          
{                              
    sizeof(my_type);                        
}

Caroline Tice 3cc8751d59 Remove references to particular Python version (use the system default 
version);  change include statements to use Python.h in the Python framework
on Mac OS X systems; leave it using regular Python.h on other systems.

a system to test it on...
