Dale Johannesen 43a2ed8611 Alignment of struct containing vectors depends on 
whether SSE is present, on Darwin anyway.  Make it
explicit.

Wojciech Matyjewicz 784d071e16 We should check that existing cast operation has the appropriate opcode before we reuse it.

Wojciech Matyjewicz 5c252865de Add a check if the initial value of the induction variable is 0 (the method comment says it should be).

Eli Friedman a62f3e1352 Expose the logic for field address codegen; it is needed for aggregate 
initializers, and I don't want to duplicate the bitfield-handling code.  
(I'll send a patch for aggregate initializers to the mailing 
list sometime soon.)

Chris Lattner 7f5c2553c7 check that terminators only occur at the end of a block. This catches the 
common problem of putting two terminators in the same block.  I can't write
a testcase for this because the .ll parser rejects this before the verifier
can, but this can occur when generating IR.

Dan Gohman 65f63eba2b Change ConstantSDNode to store an APInt instead of a uint64_t, and 
begin adding some methods to use it this way.

Steve Naroff a369922449 A bunch-o changes to fix <rdar://problem/5716046> incomplete implementation of ObjC class warning is incomplete 
As part of this fix, I made a low-level change to the text diagnostics machinery (to basically avoid printing duplicate source lines/carets when you have multiple diagnostics that refer to the same exact place). For now, this only happens with we don't have a source range (could be extended to support source ranges as well).

unsigned.

Evan Cheng 3b3286d4bc It's not always safe to fold movsd into xorpd, etc. Check the alignment of the load address first to make sure it's 16 byte aligned.

 2008-02-08 21:10:02 +00:00
Ted Kremenek 4142cc834b Changed "GetValue" methods to take an 
Expr* instead of a Stmt*, since we only
store bindings for Expr*.

Dale Johannesen 36c2967d89 64-bit (MMX) vectors do not need restrictive alignment. 
128-bit vectors need it only when SSE is on.

Steve Naroff db5f7d7699 Support fuzzy parsing MS line-oriented __asm's that originate from a macro (a case where we can't obtain source line info). As the test case indicates, we don't currently support line-oriented asm statements that mix file/macro body tokens.

Eli Friedman 1974e5321a Detabify SemaExpr. My text editor defaults to 8 spaces per tab, so it 
gets kind of annoying.

is needed.
