Chris Lattner d767a0300e Reimplement DefineTypeSize in terms of APInt. This eliminates some
magic integer arithmetic and allows it to work with types larger
than 64 bits.

Chris Lattner 190aa10fe6 rework processing of unavailable and deprecated attributes to avoid
unneeded allocation of an empty StringLiteral when these don't have

Chris Lattner adf38b3e09 change instcombine to not turn a call to non-varargs bitcast of
function prototype into a call to a varargs prototype.  We do
allow the xform if we have a definition, but otherwise we don't
want to risk that we're changing the abi in a subtle way.  On
X86-64, for example, varargs require passing stuff in %al.

Ted Kremenek d813801384 Fix tiny error in CFG construction for BinaryConditionalOperators, making sure the branch always has two successors. Also teach Environment::getSVal() about OpaqueValueExprs.
This fixes a crash reported in PR9287, and also fixes a false positive involving the value of such ternary
expressions not properly getting propagated.

Douglas Gregor 7b26ff912f Teach NestedNameSpecifier to keep track of namespace aliases the same
way it keeps track of namespaces. Previously, we would map from the
namespace alias to its underlying namespace when building a
nested-name-specifier, losing source information in the process.

Ken Dyck 8e74e79145 Use CharUnits values for Size and DataSize outside of the bitfield layout

llvm-svn: 126355
2011-02-24 01:15:17 +00:00
Ken Dyck ecfc75529f Make the Size and DataSize members more CharUnits-friendly by wrapping them
with getter and setter methods in both bit units and CharUnits. This will help
simplify some of the unit mismatch in the parts of the code where sizes are
known to be exact multiples of the width of the char type.

Assertions in the getters help guard against accidentally converting to
CharUnits when sizes are not exact multiples of the char width.

Jakob Stoklund Olesen 2b4ded329d Use the same spill slot for all live ranges that descend form the same original
register.

This avoids some silly stack slot shuffling when both sides of a copy get
spilled.

nested-name-specifier and source range to be set at the same time.

Douglas Gregor 90c9972fb2 Teach CXXScopeSpec to handle the extension of a nested-name-specifier
with another component in the nested-name-specifiers, updating its
representation (a NestedNameSpecifier) and source-location information
(currently a SourceRange) simultaneously. This is groundwork for
adding source-location information to nested-name-specifiers.

Chandler Carruth 220617c1ba Clean up the CMake test execution by nuking this directory before we try
to create it. Lit doesn't apparently clean up test directories
effectively, and so this broke randomly on subsequent runs.

Also XFAIL the test on windows, as there's not much hope for these
commands doing the right thing there.

Paired with Nick Lewycky.

Chandler Carruth 4c6fdca035 Implement a warning for known shift overflows on constant shift
expressions. Consider the code:

  int64_t i = 10 << 30;

This compiles fine, but most developers expect it to produce the value
for 10 gigs, not -2 gigs. This is actually undefined behavior because
the LHS is a signed integer type.

The warning is currently gated behind -Wshift-overflow.

There is a special case where only the sign bit is overridden that gets
a custom error message and is by default ignored. This case is much less
likely to cause observed buggy behavior, it's just undefined behavior
according to the spec. This warning can be enabled with
-Wshift-sign-overflow.

Original patch by Oleg Slezberg, with style tweaks and some correctness
fixes by me.

Jim Grosbach 0c03a3a146 Revert r125595, which is an X86-only undocumented assembly syntax extension
enabled for all targets. Non-X86 targets should not have this behavior
enabled by default.

Joerg, if you would like to resubmit with the behavior conditionalized to be
X86-ELF only, that's fine.

-Introduce EndOfFunctionNodeBuilder::withCheckerTag to allow it be "specialized" with a

-For EndOfFunctionNodeBuilder::generateNode, reverse the order of tag/P parameters since
 there are actual calls that assume the second parameter is ExplodedNode.
