Nuno Lopes 61b7fa2985 fix the quotient returned by sdivrem() for the case when LHS is negative and RHS is positive 
based on a patch by Preston Briggs, with some modifications

Johnny Chen 7a34875b3b rdar://problem/11487457 
Add convenience registers eax, ebx, ecx, edx, edi, esi, ebp, esp to the 'register read' command for x86_64.
Add a GDBRemoteRegisterContext::Addx86_64ConvenienceRegisters() method called from ProcessGDBRemote::BuildDynamicRegisterInfo().
Servicing of eax, for example, is accomplished by delegating to rax with an adjusted offset into the register context.

Jim Ingham a8558b6289 Also push file & line breakpoints past the prologue. Also added a "-K" argument to the relevant 
"break set" commands to set this per breakpoint.  Also, some CreateBreakpoint API's in the lldb_private
namespace had "internal" first and "skip_prologue" second.  "internal should always be last.  Fixed that.

Jim Grosbach 2597f83889 ARM: .end_data_region mismatch in Thumb2. 
32-bit offset jump tables just use real branch instructions and so aren't
marked as data regions. We were still emitting the .end_data_region
marker though, which assert()ed.

Sean Callanan ce8af862ae Added support for rvalue references in debug information 
(actually, mainly just hooked up support that was already
there).  Added a test case, although it's expected to fail
right now unless you're using top-of-tree LLVM.

however, the range can be unknown for the upper bound.

Sean Callanan 0259e51287 Fixed a nasty bug where JIT expressions didn't work 
when stopped in a const method.  Also updated our
testsuite to ensure that JIT is forced in this case.

Rafael Espindola 96dcb8d4bb Function template version of the previous patch. 
llvm-svn: 157207
 2012-05-21 20:31:27 +00:00
Rafael Espindola 93c289c28a Produce a hidden symbol for zed in 
struct HIDDEN foo {
  };
  template <class P>
  struct bar {
  };
  template <>
  struct HIDDEN bar<foo> {
    DEFAULT static void zed();
  };
  void bar<foo>::zed() {
  }

Before we would produce a hidden symbol in

  struct HIDDEN foo {
  };
  template <class P>
  struct bar {
  };
  template <>
  struct bar<foo> {
    DEFAULT static void zed();
  };
  void bar<foo>::zed() {
  }

But adding HIDDEN to the specialization would cause us to produce a default
symbol.

Benjamin Kramer a63d9531dd Unpack enums in CodeCompletetionResult.

Jakob Stoklund Olesen 29268b50f2 Give a small negative bias to giant edge bundles. 
This helps compile time when the greedy register allocator splits live
ranges in giant functions. Without the bias, we would try to grow
regions through the giant edge bundles, usually to find out that the
region became too big and expensive.

If a live range has many uses in blocks near the giant bundle, the small
negative bias doesn't make a big difference, and we still consider
regions including the giant edge bundle.

Giant edge bundles are usually connected to landing pads or indirect
branches.
