Track volatile aggregate copies better. I'm hoping someone else will decide
how to get the backend to know that the operation is volatile.

llvm-svn: 72348

Fix thinko, and implement aggregate volatile reads.

llvm-svn: 72347

More volatile fixes. Can't testcase these yet as ultimately volatile
is still ignored.

llvm-svn: 72344

Collapse a few FIXMEs together and refactor to make fixing the code easier.

llvm-svn: 72342

One step to fixing up codegen for a=b, where a is a volatile struct.

llvm-svn: 72315

Fix typo.

llvm-svn: 72308

Have AggExprEmitter::VisitCXXConstructExpr make new variables if necessary. Stub out VisitCXXExprWithTemporaries.

llvm-svn: 72103

Reflow some comments.

llvm-svn: 71937

Make codegen for constructors work again.

llvm-svn: 70785

fix PR4067: [Linux kernel] cannot aggregate codegen stmtexpr as lvalue

llvm-svn: 70067

fix PR4026: Clang can't codegen __func__ without implicit cast

llvm-svn: 69747

Implement basic code generation of constructor calls. We can now compile:

struct S {
S(int, int);
};

void f() {
S s(10, 10);
}

llvm-svn: 69330

Minor work related to removing the assumption that value initialization
implies an all-zero bit pattern.

llvm-svn: 68994

Propagate the ASTContext to various AST traversal and lookup functions.
No functionality change (really).

llvm-svn: 68726

Minor cleanup.

llvm-svn: 67896

Remove dead code.

llvm-svn: 67477

Add codegen support for aggregate BlockDeclRefExprs.

brain thinking memcpy, fingers thinking memset :)

after going around in circles a few times, finally cave and emit structure
copies with memcpy instead of memmove. This matches what GCC does and if it
causes a problem with a particular libc we can

after going around in circles a few times, finally cave and emit structure
copies with memcpy instead of memmove. This matches what GCC does and if it
causes a problem with a particular libc we can always fix it with a target
hook.

rip out __builtin_overload

llvm-svn: 64961

Use EmitVAListRef instead of EmitLValue directly to handle array decay
case on x86_64.

llvm-svn: 64333

Make CodeGen produce an error if we come across a non-constant initializer list that involves the GNU array-range designator extension

llvm-svn: 63327

Introduce a new expression node, ImplicitValueInitExpr, that

Introduce a new expression node, ImplicitValueInitExpr, that
represents an implicit value-initialization of a subobject of a
particular type. This replaces the (ab)use of CXXZeroValueInitExpr
within initializer lists for the "holes" that occur due to the use of
C99 designated initializers.

The new test case is currently XFAIL'd, because CodeGen's
ConstExprEmitter (in lib/CodeGen/CGExprConstant.cpp) needs to be
taught to value-initialize when it sees ImplicitValueInitExprs.

Clean up designated initialization of unions, so that CodeGen doesn't
have to try to guess which member is being initialized.

llvm-svn: 63315

Improvements to code-generation and semantic analysis of designated
initializers.

- We now initialize unions properly when a member other than the
first is named by a designated initializer.

Improvements to code-generation and semantic analysis of designated
initializers.

- We now initialize unions properly when a member other than the
first is named by a designated initializer.
- We now provide proper semantic analysis and code generation for
GNU array-range designators *except* that side effects will occur
more than once. We warn about this.
