John McCall 05ddbb80d2 Implement the standard mangling for array-subscript expressions, and implement 
the current proposals from David Vandervoorde for new, delete, throw, typeid,
imaginary literals, string literals, and null literals.

Dan Gohman 1f471435f8 Don't propagate debug locations to instructions for materializing 
constants, since they may not be emited near the other instructions
which get the same line, and this confuses debug info.

John McCall 11e577b99a Work around an obnoxious GCC warning by changing semantics in a hopefully- 
harmless way.

llvm-svn: 108295
 2010-07-13 23:19:49 +00:00
Douglas Gregor 51954276cc Introduce a new cast kind for an "lvalue bitcast", which handles 
reinterpret_casts (possibly indirectly via C-style/functional casts)
on values, e.g., 

  int i;
  reinterpret_cast<short&>(i);

The IR generated for this is essentially the same as for

  *reinterpret_cast<short*>(&i).

Fixes PR6437, PR7593, and PR7344.

John McCall 5c08ab956b Allow for the possibility that __cxa_end_catch might throw for a catch-all block 
or a catch of a record type by value or reference.  Also convert this to a
lazy cleanup.

John McCall 2b7fc3828e Teach IR generation how to lazily emit cleanups. This has a lot of advantages, 
mostly in avoiding unnecessary work at compile time but also in producing more
sensible block orderings.

Move the destructor cleanups for local variables over to use lazy cleanups.
Eventually all cleanups will do this;  for now we have some awkward code
duplication.

Tell IR generation just to never produce landing pads in -fno-exceptions.
This is a much more comprehensive solution to a problem which previously was
half-solved by checks in most cleanup-generation spots.

Dale Johannesen caca5488dc In inline asm treat indirect 'X' constraint as 'm'.

than asserting which it was doing before.  PR 7528.

Jakob Stoklund Olesen fc4b8b8e80 Add an assertion to make PR7542 fail consistently. 
LiveInterval::overlapsFrom dereferences end() if it is called on an empty
interval.

It would be reasonable to just return false - an empty interval doesn't overlap
anything, but I want to know who is doing it first.

construct is the named metadata.

Dan Gohman afd69cf5b7 Add support for empty named metadata too. This isn't particularly 
useful, but it is nice for consistency.

Evan Cheng 0cc4ad983d Extend the r107852 optimization which turns some fp compare to code sequence using only i32 operations. It now optimize some f64 compares when fp compare is exceptionally slow (e.g. cortex-a8). It also catches comparison against 0.0.
