2011-06-21Driver/Darwin: Fixup version check for -object_path_lto support.Daniel Dunbar

2011-06-21Fix the default libc++ header search path to be sysrooted. Radar 9639692.Bob Wilson
The -cxx-isystem path is not prefixed with the sysroot directory, so it's not a good way for the driver to set the system default C++ search path. Instead, add -stdlib as a cc1 option and teach the frontend how to find the headers. The driver can then just pass -stdlib through to "cc1". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@133547 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-21IRgen: Add a -fuse-register-sized-bitfield-access option, for testing.Daniel Dunbar
- Changes bit-field access policy to try to use (aligned) register sized accesses. The idea here is that by using larger accesses we expose more coalescing potential to the backend when we have situations like adjacent bit-fields in the same structure (which is common), and that the backend should be smart enough to narrow the accesses down when no coalescing is done or when it is shown not to be profitable. -- $ clang -m32 -O3 -S -o - t.c _f0: ## @f0 pushl %ebp movl %esp, %ebp movl 8(%ebp), %eax movb (%eax), %cl andb $-128, %cl orb $1, %cl movb %cl, (%eax) movb 1(%eax), %cl andb $-128, %cl orb $1, %cl movb %cl, 1(%eax) movb 2(%eax), %cl andb $-128, %cl orb $1, %cl movb %cl, 2(%eax) movb 3(%eax), %cl andb $-128, %cl orb $1, %cl movb %cl, 3(%eax) popl %ebp ret $ clang -m32 -O3 -S -o - t.c -Xclang -fuse-register-sized-bitfield-access _f0: ## @f0 pushl %ebp movl %esp, %ebp movl 8(%ebp), %eax movl $-2139062144, %ecx ## imm = 0xFFFFFFFF80808080 andl (%eax), %ecx orl $16843009, %ecx ## imm = 0x1010101 movl %ecx, (%eax) popl %ebp ret -- git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@133532 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-21Introduce a new AST node describing reference binding to temporaries.Douglas Gregor
MaterializeTemporaryExpr captures a reference binding to a temporary value, making explicit that the temporary value (a prvalue) needs to be materialized into memory so that its address can be used. The intended AST invariant here is that a reference will always bind to a glvalue, and MaterializeTemporaryExpr will be used to convert prvalues into glvalues for that binding to happen. For example, given const int& r = 1.0; The initializer of "r" will be a MaterializeTemporaryExpr whose subexpression is an implicit conversion from the double literal "1.0" to an integer value. IR generation benefits most from this new node, since it was previously guessing (badly) when to materialize temporaries for the purposes of reference binding. There are likely more refactoring and cleanups we could perform there, but the introduction of MaterializeTemporaryExpr fixes PR9565, a case where IR generation would effectively bind a const reference directly to a bitfield in a struct.

2011-06-20Change how PHINodes store their operands.Jay Foad
Change PHINodes to store simple pointers to their incoming basic blocks, instead of full-blown Uses. Note that this loses an optimization in SplitCriticalEdge(), because we can no longer walk the use list of a BasicBlock to find phi nodes. See the comment I removed starting "However, the foreach loop is slow for blocks with lots of predecessors". Extend replaceAllUsesWith() on a BasicBlock to also update any phi nodes in the block's successors. This mimics what would have happened when PHINodes were proper Users of their incoming blocks. (Note that this only works if OldBB->replaceAllUsesWith(NewBB) is called when OldBB still has a terminator instruction, so it still has some successors.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@133435 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-20Move away from the poor "abstraction" I added to Type. John arguedChandler Carruth
effectively that this abstraction simply doesn't exist. That is highlighted by the fact that by using it we were papering over a more serious error in this warning: the fact that we warned for *invalid* constructs involving member pointers and block pointers. I've fixed the obvious issues with the warning here, but this is confirming an original suspicion that this warning's implementation is flawed.
