Reid Spencer 309080abbc Fix PR902: 
Errors are generated with the YYERROR macro which can only be called from
a production (inside yyparse) because of the goto statement in the macro.
This lead to several situations where GEN_ERROR was not called but
GenerateError was used instead (because it doesn't use YYERROR). However,
in such situations, catching the error much later (e.g. at the end of
the production) is not sufficient because LLVM can assert on invalid data
before the end of the production is reached. The solution is to ensure that
the CHECK_FOR_ERROR macro (which invokes YYERROR if there's an error) is
used as soon as possible after a call to GenerateError has been made.

Bill Wendling 5d409822d6 "Once more into the breach, dear friends, once more, or fill the wall up

No! Really! Serious this time...It was how the vreg uses were being
adjusted that was causing hte Olden tests to fail. I corrected this and
the Olden and Regression tests all passed.

Evan Cheng d31f55c236 PEI now place callee save spills closest to the address pointed to by the

Evan Cheng 17a8d08dba - Added a hook processFunctionBeforeCalleeSaveScn(). This is called by PEI just 
before it determines which callee-save registers are to be spilled. This allows
the target to make changes such as forcing certain physical registers to be
spilled.
- Modified comments. It's important to note the order of registers in the array
returns by getCalleeSaveRegs() determines the order of callee save spill code.

Chris Lattner 6bd6da4097 Be far more careful when splitting a loop header, either to form a preheader 
or when splitting loops with a common header into multiple loops.  In particular
the old code would always insert the preheader before the old loop header.  This
is disasterous in cases where the loop hasn't been rotated.  For example, it can
produce code like:

        .. outside the loop...
        jmp LBB1_2      #bb13.outer
LBB1_1: #bb1
        movsd 8(%esp,%esi,8), %xmm1
        mulsd (%edi), %xmm1
        addsd %xmm0, %xmm1
        addl $24, %edi
        incl %esi
        jmp LBB1_3      #bb13
LBB1_2: #bb13.outer
        leal (%edx,%eax,8), %edi
        pxor %xmm1, %xmm1
        xorl %esi, %esi
LBB1_3: #bb13
        movapd %xmm1, %xmm0
        cmpl $4, %esi
        jl LBB1_1       #bb1

Note that the loop body is actually LBB1_1 + LBB1_3, which means that the
loop now contains an uncond branch WITHIN it to jump around the inserted
loop header (LBB1_2).  Doh.

This patch changes the preheader insertion code to insert it in the right
spot, producing this code:

        ... outside the loop, fall into the header ...
LBB1_1: #bb13.outer
        leal (%edx,%eax,8), %esi
        pxor %xmm0, %xmm0
        xorl %edi, %edi
        jmp LBB1_3      #bb13
LBB1_2: #bb1
        movsd 8(%esp,%edi,8), %xmm0
        mulsd (%esi), %xmm0
        addsd %xmm1, %xmm0
        addl $24, %esi
        incl %edi
LBB1_3: #bb13
        movapd %xmm0, %xmm1
        cmpl $4, %edi
        jl LBB1_2       #bb1

Totally crazy, no branch in the loop! :)
