Ted Kremenek 5b24adda26 Add optional record of "location" SVals in the environment. When we analyzing loads/stores, we lose the location SVal, which makes it difficult to recover in some cases (e.g., for post diagnostics). This is prep for pending changes to GRExprEngine.

 2010-09-03 01:07:02 +00:00
Ted Kremenek db4c128f2f Add GRState::getSimplifiedSVal(), which provides an API hook for doing symbol -> constant folding. This isn't used yet, but 
is prep for some pending optimizations in GRExprEngine.

Anders Carlsson af7534f084 Get rid of the "functions declared 'noreturn' should have a 'void' result type" warning. 
The rationale behind this is that it is normal for callback functions to have a non-void return type
and it should still be possible to mark them noreturn. (JavaScriptCore is a good example of this).

John McCall 12d3891a27 It's not safe to use the generic CXXMethodDecl overload of CGT::getFunctionInfo 
to set up a destructor call, because ABIs can tweak these conventions.
Fixes rdar://problem/8386802.

Daniel Dunbar a70fab8dd7 IRgen/Obj-C: Rewrite Objective-C bit-field access to compute the access strategy 
using the same methods as used for normal structures.
 - This fixes problems with reading past the end of the structure and with
   handling straddled bit-field access.

Tom Care 796ed50433 Reapply 112850 and 112839 with a constructor for the BinaryOperatorData struct. Clang would zero out the enum and pointer in the struct in some conditions, but GCC would never zero out the values.

Chris Lattner fb483625b1 reapply 112894: 
Remove #uses comments from functions: they we're padded out to column 50
and were potentially confusing for externally visible functions.

going further, remove the "<i8**> [#uses=3]" comments entirely. They
add a lot of noise, confuse people about what the IR is, and don't add 
any particular value.  When the types are long it makes it really really
hard to read IR.

If someone is interested in this sort of thing, the right way to do this
is to implement an AsmAnnotationWriter that produces the same output, and
add a flag to llvm-dis (only) to produce this output.

Chris Lattner 60c160ff4d remove some tests that aren't adding any value: the check lines don't 
make it clear what they're testing so there is no way to know it's right
or to update it.

Dan Gohman 2adf2f2714 Use the FindProgramByName fallback only with known absolute paths. 
I wasn't able to convince myself that all GetMainExecutable
implementations always return absolute paths; this prevents
unexpected behavior in case they ever don't.

Jim Grosbach 7fd9aea67c For ARM stack frames that utilize variable sized objects and have either 
large local stack areas or require dynamic stack realignment, allocate a
base register via which to access the local frame. This allows efficient
access to frame indices not accessible via the FP (either due to being out
of range or due to dynamic realignment) or the SP (due to variable sized
object allocation). In particular, this greatly improves efficiency of access
to spill slots in Thumb functions which contain VLAs.

Bill Wendling ec9b5fe131 - Change __builtin_ia32_palignr intrinsic type to match the pattern in clang. 
- Add patterns to match the following MMX builtins:

   * __builtin_ia32_vec_init_v8qi
   * __builtin_ia32_vec_init_v4hi
   * __builtin_ia32_vec_init_v2si
   * __builtin_ia32_vec_ext_v2si

  These builtins do not correspond to a single MMX instruction. They will have
  to be lowered -- most likely in the back-end.
