Chris Lattner be49c03ff4 use the new optimized debug info metadata accessors. In 
addition to the inherent win, this eliminates the pointless
cost of going through the name -> mdkind stringmap that we
were paying.

John McCall cef1582923 Support __attribute__((unused)) on types. This suddenly started firing 
a lot for me on selfhosts, I dunno why.

Daniel Dunbar 034299ef25 IRGen: Move the auxiliary data structures tracking AST -> LLVM mappings out of CodeGenTypes, to per-record CGRecordLayout structures. 
- I did a cursory check that this was perf neutral, FWIW.

 2010-03-31 01:09:11 +00:00
Daniel Dunbar e75a64f2d3 CGRecordLayoutBuilder: Switch unions to use same mechanism for tracking field and bit-field info as structs. 
- Anders, please check.

Douglas Gregor d7f18dd750 Drastically simplify the computation of linkage for typeinfo by using 
the existing (and already well-tested) linkage computation for types,
with minor tweaks for dynamic classes and (pointers to) incomplete
types. Fixes PR6597.

 2010-03-30 23:58:36 +00:00
John McCall d9c7c6568e Introduce a new kind of derived-to-base cast which bypasses the need for 
null checks, and make sure we elide null checks when accessing base class
members.

Jakob Stoklund Olesen 4d2972d793 Slightly relax test case. An upcoming LLVM commit will change the xor instruction.

Rafael Espindola 49b85ab6e6 Remember the regparm attribute in FunctionType::ExtInfo. 
Fixes PR3782.

 2010-03-30 22:15:11 +00:00
Argyrios Kyrtzidis 998d51b98f When "delayed parsing" C++ default arguments, if there is an error, there may be tokens left in the token stream 
that will interfere (they will be parsed as if they are after the class' '}') and a crash will occur because
the CachedTokens that holds them will be deleted while the lexer is still using them.

Make sure that the tokens of default args are removed from the token stream.
Fixes PR6647.

llvm-svn: 99939
 2010-03-30 22:14:32 +00:00
Douglas Gregor 504662f28f Add a test for C++ [stmt.select]p3, which specifies that redeclaring a 
name in the outermost block of a if/else that declares the same name
is ill-formed. Turns out that Clang and MSVC were right about PR6739;
GCC is too lax.

John McCall 16df1e59f2 Propagate the "found declaration" (i.e. the using declaration instead of 
the underlying/instantiated decl) through a lot of API, including "intermediate"
MemberExprs required for (e.g.) template instantiation.  This is necessary
because of the access semantics of member accesses to using declarations:
only the base class *containing the using decl* need be accessible from the
naming class.

This allows us to complete an access-controlled selfhost, if there are no
recent regressions.

Rafael Espindola 5c61cbeb58 Fix this test on windows. When running on windows we print 
double 0.000000e+000
instead of

llvm-svn: 99930
 2010-03-30 21:02:45 +00:00
Douglas Gregor 607f14168a Improve diagnostics when printing a template instantiation backtrace 
involving substitution of deduced template arguments into a class
template partial specialization or function template, or when
substituting explicitly-specific template arguments into a function
template. We now print the actual deduced argument bindings so the
user can see what got deduced.

Ted Kremenek 2d107f9d1d RegionStore: specially handle loads from integer global variables declared 'const'.

Rafael Espindola c50c27cca8 the big refactoring bits of PR3782. 
This introduces FunctionType::ExtInfo to hold the calling convention and the
noreturn attribute. The next patch will extend it to include the regparm
attribute and fix the bug.

llvm-svn: 99920
 2010-03-30 20:24:48 +00:00
Douglas Gregor ad2c6988a2 Introduce new AST statistics that keep track of the number of isa (or 
dyn_cast) invocations for C++ and Objective-C types, declarations,
expressions, and statements. The statistics will be printed when
-print-stats is provided to Clang -cc1, with results such as:

277073 clang - Number of checks for C++ declaration nodes
 13311 clang - Number of checks for C++ expression nodes
    18 clang - Number of checks for C++ statement nodes
174182 clang - Number of checks for C++ type nodes
 92300 clang - Number of checks for Objective-C declaration nodes
  9800 clang - Number of checks for Objective-C expression nodes
     7 clang - Number of checks for Objective-C statement nodes
 65733 clang - Number of checks for Objective-C type nodes

The statistics are only gathered when NDEBUG is not defined, since
they introduce potentially-expensive operations into very low-level
routines (isa).

Ted Kremenek 4be6a75884 Change the analyzer to recognize (but ignore) assignments to isa. Fixes PR 6302.
