llvm-svn: 141597
 2011-10-10 23:36:56 +00:00
Eli Friedman 192e034aab A couple random preprocessor changes that got ported from C99 to C++11.

 2011-10-10 23:35:28 +00:00
Johnny Chen 541b98517e Remove test logic to check for clang and skip the rest due to insufficient debug info. 
Recent changes in lldb inlining robustness seem to have fixed it.

Bill Wendling 0a10cdc704 If the CPSR is defined by a copy, then we don't want to merge it into an IT 
block. E.g., if we have:

  movs  r1, r1
  rsb   r1, 0
  movs  r2, r2
  rsb   r2, 0

we don't want this to be converted to:

  movs  r1, r1
  movs  r2, r2
  itt   mi
  rsb   r1, 0
  rsb   r2, 0

Ted Kremenek 8f34b6999c [analyzer] Teach the static analyzer about CXXForRangeStmt. Patch by Jim Goodnow II! 
llvm-svn: 141587
 2011-10-10 22:36:31 +00:00
Ted Kremenek bed648e0b0 Rework construction of CXXForRangeStmt not to recycle the same DeclRefExpr in multiple subexpressions. This breaks the tree structure 
of the AST and completely breaks the CFG invariants.

Patch by Jim Goodnow II and reviewed by Richard Smith!

Eli Friedman 8ec0897db6 Make sure the X86 backend doesn't explode on 128-bit shuffles in AVX mode. Fixes PR11102. 
llvm-svn: 141585
 2011-10-10 22:28:47 +00:00
Johnny Chen a10e6c1052 Add '-e' and '-x' options to the test driver to be able to specify an executable (full path) 
and the breakpoint specification for the benchmark purpose.  This is used by TestSteppingSpeed.py
to benchmark the lldb stepping speed.  Without '-e' and 'x' specified, the test defaults to
run the built lldb against itself and stopped on Driver::MainLoop, then stepping for 50 times.

Nick Lewycky fcf8462583 Add support for dumping section headers to llvm-objdump. This uses the same 
flags as binutils objdump but the output is different, not just in format but
also showing different sections. Compare its results against readelf, not
objdump.

Jakob Stoklund Olesen add0c43ebb Give targets a chance to expand even standard pseudos. 
Allow targets to expand COPY and other standard pseudo-instructions
before they are expanded with copyPhysReg().

This allows the target to examine the COPY instruction for extra
operands indicating it can be widened to a preferable super-register
copy.  See the ARM -widen-vmovs option.

 2011-10-10 20:32:03 +00:00
Jakob Stoklund Olesen a1ac0dab2d Emit full ED initializers even for pseudo-instructions. 
This should unbreak the picky buildbots.

Andrew Trick b9d67ccc23 Allow stat += 0 without activating the stat. 
For me, this is a nice convenience. We generally want grep to match
stats output only when the event has occurred.

Douglas Gregor ab96bcf6ea When substituting into a sizeof parameter pack expression in a context 
where we can't expand (i.e., multi-level substitution), be sure to
substitute the pack with its level-reduced pack. Fixes PR10230.

Jakob Stoklund Olesen ba0bc4f522 Mark the standard pseudos as isPseudo = 1. 
The difference between isPseudo and isCodeGenOnly is a bit murky, but
isCodeGenOnly should eventually go away.  It is used for instructions
that are clones of real instructions with slightly different properties.

The standard pseudo-instructions never mirror real instructions, so they
are definitely in the isPseudo category.

Bob Wilson 391214aa3a Partially revert r141374: allow use of libc++ prior to Mac OS X 10.7. 
Apple only supports libc++ on OS X 10.7 and later but for the open-source
compiler that restriction doesn't make sense.

Chad Rosier fd3c90c620 When an included non-system directory duplicates a system directory the clang 
frontend removes the non-system directory to maintain gcc compatibility.  When
this happens NumAngled needs to be updated.

Bruno Cardoso Lopes cc6659b2ae The Mips specific function for instruction cache invalidation cannot be 
compiled on mips32r1 processors because it uses synci and rdhwr instructions
which are supported only on mips32r2, so I replaced this function with the
call to function cacheflush which works for both mips32r1 and mips32r2.

 2011-10-10 18:34:56 +00:00
Jakob Stoklund Olesen b253f490c3 Insert dummy ED table entries for pseudo-instructions. 
The table is indexed by opcode, so simply removing pseudo-instructions
creates a wrong mapping from opcode to table entry.

Add a test case for xorps which has a very high opcode that exposes this
problem.

Richard Smith caf3390d44 Constant expression evaluation refactoring: 
- Remodel Expr::EvaluateAsInt to behave like the other EvaluateAs* functions,
   and add Expr::EvaluateKnownConstInt to capture the current fold-or-assert
   behaviour.
 - Factor out evaluation of bitfield bit widths.
 - Fix a few places which would evaluate an expression twice: once to determine
   whether it is a constant expression, then again to get the value.

it might be wrong for other instantiations of the same function
template. Fixes PR10801.

Sebastian Redl 6ce53ae752 Now that we support move generation, mention this in the language extension and C++ status pages. Also update the C++ status for default functions, which are complete now that we can generate move functions, and destructor exception specifications, which I did a while ago.

Richard Smith f368fb40df constexpr: Disable checking of constructor member initializer lists for 
constexpr constructor templates. Such checking is optional, and currently hard
to get right since clang doesn't generate implicit member initializers until
instantiation (even for non-dependent members).

This is needed for clang to accept libstdc++ from g++4.6 in c++0x mode.
