Evan Cheng 35ff79370b Local spiller optimization: 
Turn a store folding instruction into a load folding instruction. e.g.
     xorl  %edi, %eax
     movl  %eax, -32(%ebp)
     movl  -36(%ebp), %eax
     orl   %eax, -32(%ebp)
=>
     xorl  %edi, %eax
     orl   -36(%ebp), %eax
     mov   %eax, -32(%ebp)
This enables the unfolding optimization for a subsequent instruction which will
also eliminate the newly introduced store instruction.

Duncan Sands d9834b29dd If the value types are equal then this routine 
asserts in later checks rather than producing
the ordinary load it is supposed to.  Avoid all
such hassles by directly returning an ordinary
load in this case.

Rafael Espindola 813a0b1d29 Test byval with a 8 bit aligned struct 
llvm-svn: 43173
 2007-10-19 11:29:21 +00:00
Rafael Espindola 846c19dd70 Add support for byval function whose argument is not 32 bit aligned. 
To do this it is necessary to add a "always inline" argument to the
memcpy node. For completeness I have also added this node to memmove
and memset.  I have also added getMem* functions, because the extra
argument makes it cumbersome to use getNode and because I get confused
by it :-)

Steve Naroff 684dc4107f Fix the previous (short lived:-) FIXME. 
I didn't realize that GCC considers this a hard error (I thought it was built-in).

Since it's not, we should simply emit an error.

[dylan:~/llvm/tools/clang] admin% cc -c trivial.m
trivial.m:6: error: cannot find interface declaration for 'NSConstantString'

[administrators-powerbook59:~/llvm/tools/clang] admin% ../../Debug/bin/clang trivial.m

Ted Kremenek 04746ce6f9 Fixed DeclStmt::child_begin() to actually create an iterator that 
visits its decls, rather than just creating an "end()" iterator.

Fixed child_end() for statements and expressions to use
child_iterator() to create the end() iterator, rather than just
returning NULL.

Fixed bug in StmtIterator where we did not correctly detect if we had
marched off the end of the ScopedDecls.

Evan Cheng 463e2ab0ac - Added getOpcodeAfterMemoryUnfold(). It doesn't unfold an instruction, but only returns the opcode of the instruction post unfolding. 
- Fix some copy+paste bugs.

integer constant.
