function.

 2010-05-18 22:51:59 +00:00
Douglas Gregor 4618868a7d Implement C++ support for vector and extended vector types. This 
involves extending implicit conversion sequences to model vector
conversions and vector splats, along with teaching the C++ conditional
operator-checking code about vector types.

Fixes <rdar://problem/7983501>.

Dan Gohman 06ab08f795 Print an error message in Formula::print if the HasBaseReg flag 
is inconsistent with the BaseRegs field. It's not print's job to
assert on an invalid condition, but it can make one more obvious.

Chris Lattner 9f46539e07 make mcinstlower remove all but the first operand to CALL64pcrel32. 
The register use operands (e.g. the first argument is passed in a 
register) is currently being modeled as a normal register use,
instead of correctly being an implicit use.  This causes the operand
to get propagated onto the mcinst, which was causing the encoder to
emit a rex prefix byte, which generates an invalid call.

This fixes rdar://7998435

Jakob Stoklund Olesen 663543b4d7 Properly handle multiple definitions of a virtual register in the same 
instruction.

This can happen on ARM:

>> %reg1035:5<def>, %reg1035:6<def> = VLD1q16 %reg1028, 0, pred:14, pred:%reg0
Regs: Q0=%reg1032* R0=%reg1028* R1=%reg1029* R2 R3=%reg1031*
Killing last use: %reg1028
Allocating %reg1035 from QPR
Assigning %reg1035 to Q1
<< %D2<def>, %D3<def> = VLD1q16 %R0<kill>, 0, pred:14, pred:%reg0, %Q1<imp-def>

Ted Kremenek 49be9e0819 Teach CursorVisitor about duplicate ObjCPropertyDecls that can arise because of a current 
design limitation in how we handle Objective-C class extensions.  This was causing the CursorVisitor
to essentially visit an @property twice (once in the @interface, the other in the class extension).

Kevin Enderby 7bcc9e9450 Incorporate Daniel's suggestion and use !isdigit(CurPtr[0]) and not 
CurPtr[0] == '\n' when testing the character after a "0b" when looking
to see if it part of a something like "jmp 0b".

Kevin Enderby 53e0631516 Fixed the problem with a branch to "0b" that was not parsed by llvm-mc 
correctly.  The Lexer was incorrectly eating the newline casusing it to branch
to address 0.  Updated the test case to use a "0:" label and a branch to "0b".

Douglas Gregor 86ad085b40 Give a slight edge to the context-sensitive keyword 'super' over 
non-function-local declarations with names similar to what the user
typed. For example, this allows us to correct 'supper' to 'super' in
an Objective-C message send, even though the C function 'isupper' has
the same edit distance.

Douglas Gregor 5fd04d4832 Tweak typo-correction logic a bit regarding "super", so that we 
consider "super" as a candidate whenever we're parsing an expression
within an Objective-C method in an interface that has a superclass. At
some point, we'd like to give "super" a little edge over non-local
names; that will come later.
