the anonymous namespace to its parent. Semantically, this means that
the anonymous namespaces defined in one module are distinct from the

Always allow redefinition of typedefs when modules are enabled. This
...
is important because it's fairly common for headers (especially system
headers) to want to provide only those typedefs needed for that
particular header, based on some guard macro, e.g.,
#ifndef _SIZE_T
#define _SIZE_T
typedef long size_t;
#endif
which is repeated in a number of headers. The guard macro protects
against duplicate definitions. However, this means that only the first
occurrence of this pattern actually defines size_t, so the submodule
corresponding to this header has the only visible definition. If a
user then imports a different submodule from the same module, size_t
will be known but not visible, and therefore cannot be used.
By allowing redefinition of typedefs, each header that wants to define
size_t can do so independently, so it will be available in the
corresponding submodules.

Don't rely on the fact that shift values are never very large, and thus
...
this substraction will result in small negative numbers at worst which
become very large positive numbers on assignment and are thus caught by
the <=4 check on the next line. The >0 check clearly intended to catch
these as negative numbers.
Spotted by inspection, and impossible to trigger given the shift widths
that can be used.

Move SSE2 logical operations PAND/POR/PXOR/PANDN above SSE1 logical operations ANDPS/ORPS/XORPS/ANDNPS. This fixes a pattern ordering issue that meant that the SSE2 instructions could never be directly selected since the SSE1 patterns would always match first. This is largely moot with the ExeDepsFix pass, but I'm trying to audit for all such ordering issues.

First brush with testing __gxx_personality_v0 reveals there is still a long way to go. But my understanding of what it is supposed to do continues to improve.

Correct comment regarding members of __cxa_dependent_exception. Actually it is useful to disguise a __cxa_dependent_exception as a __cxa_exception by filling in most (not all) of these members at __cxa_dependent_exception construction time. That way most routines don't have to care which kind of exception they have.

Fixed an ARM backtracing issue where if the previous frame was a thumb
function and it was a tail call so that the current frame returned to
an address that would fall into the next function, we would use the
next function as the basis for how we unwound the previous frame's
registers and of course get things wrong. We now fix the PC code
address using the current ABI plug-in, and the ARM ABI plug-in has
been modified to correctly fix the code address. So when we do the
symbol context lookup, instead of taking an address like 0x1001 and
decrementing 1, and looking up the symbol context for a frame, we
now correctly fix 0x1001 to 0x1000, then decrement that by 1 to
get the correct symbol context.
I added a bunch more logging to "log enable lldb uwnind" to help
us in the future. We now log the PC, FP and SP (if they are available),
and we also dump the "active_row" that we find for unwinding a frame.
