Douglas Gregor b278aafbfb Allocate CodeCompletionString and all of its components in a 
BumpPtrAllocator, rather than manually new/delete'ing them. This
optimization also allows us to avoid allocating memory for and copying
constant strings (e.g., "return", "class").

This also required embedding the priority and availability of results
within the code completion string, to avoid extra memory allocation
within libclang.

David Greene 433c6180ab [AVX] Implement EnforceSmallerThan for mixed int/fp type lists. This 
makes type checking for extract_subvector and insert_subvector more
robust and will allow stricter typechecking of more patterns in the
future.

This change handles int and fp as disjoint sets so that it will
enforce integer types to be smaller than the largest integer type and
fp types to be smaller than the largest fp type.  There is no attempt
to check type sizes across the int/fp sets.

Johnny Chen 3d9011d6dd Add EmulateVPOP() to the g_arm_opcodes and g_thumb_opcodes tables, which represents 
an operation to load multiple extension registers from the stack.

Argyrios Kyrtzidis 8b6ec6870f Warn for "if ((a == b))" where the equality expression is needlessly wrapped inside parentheses. 
It's highly likely that the user intended an assignment used as condition.

Addresses rdar://8848646.

Ted Kremenek 5b4288440d Add temporary hack to -Wuninitialize to create a separate CFG (for C++ code) that doesn't include implicit dtors. 
Implicit dtors confuse the ad hoc path-sensitivity of UninitializedValuesV2.cpp.  This isn't
the ideal solution, as it will directly impact compile time, but should significantly reduce
the noise of -Wuninitialized on some code bases.

This immediately "fixes" the false positive reported in PR 9063, although this
isn't the right fix in the long run.

Ted Kremenek ba357296e7 Enhance -Wuninitialized to better reason about || and &&, tracking dual dataflow facts and properly merging them.

Douglas Gregor 1732850158 Fix a thinko where I didn't update a consistency check for 
PackExpansionType in the AST reader. We need more testing for variadic
templates + PCH, but this fixes PR9073.

pattern matching can also pattern match undef, creating a more uniform
style.

John McCall 04fcd0d58f The code trying to assign a typedef to an anonymous tag declaration was 
extremely rambunctious, both on parsing and on template instantiation.
Calm it down, fixing an internal consistency assert on anonymous enum
instantiation manglings.

Argyrios Kyrtzidis 0d349f9b8a When initializing struct members, the important thing is that the "initializing" expression is 
compatible, not having the same type.

Fix rdar://8183908 in which compatible vector types weren't initialized properly leading to a crash.

Rafael Espindola 08bccdad19 Don't tell the linker about available_externally definitions. If we do, it will 
complain about duplicated definitions.

llvm-svn: 124634
 2011-02-01 00:41:51 +00:00
Rafael Espindola 9fa5a67d3d Set visibility for available_externally globals. This is important for two reasons: 
* llvm-link would complains about mismatched visibility
* If we produce a relocation with an available_externally, it is good to know that
it is hidden.
