Evan Cheng 0e4df63bd5 Update test to match 95961. 
llvm-svn: 95971
 2010-02-12 07:48:46 +00:00
Anders Carlsson e8a9756e63 Keep track of the address points for all primary bases, and add the ability to dump multiple address points for a single offset.

Douglas Gregor f40863caff Work around an annoying, non-standard optimization in the glibc 
headers, where malloc (and many other libc functions) are declared
with empty throw specifications, e.g.,  

  extern void *malloc (__SIZE_TYPE__ __size) throw () __attribute__
  ((__malloc__)) ;

The C++ standard doesn't seem to allow this, and redeclaring malloc as
the standard permits (as follows) resulted in Clang (rightfully!)
complaining about mis-matched exception specifications.

  void *malloc(size_t size);

We work around this by silently propagating an empty throw
specification "throw()" from a function with C linkage declared in a
system header to a redeclaration that has no throw specifier.

Ick.

John McCall 84c416b9f6 Fix a bug causing an assertion when a covariant return type differed from 
an overriden type only by reduced qualification.

Douglas Gregor 87b4b4184c Improve a test slightly

 2010-02-12 06:08:51 +00:00
Douglas Gregor d3a5918742 In C++, allow builtins to be referred to via qualified name lookup, e.g., 
::__builtin_va_copy

Fixes one of the Firefox issues in PR5511.

 2010-02-12 05:48:04 +00:00
Anders Carlsson 65b4978f7f More work on vtable layout. We can now layout vtables with primary bases. 
llvm-svn: 95965
 2010-02-12 05:25:12 +00:00
John McCall 62d5d64ce9 Waste two bits in every clang::Type so that the type class can be read 
in a single byte-load rather than some crazy bitmunging operation.

llvm-svn: 95964
 2010-02-12 03:41:30 +00:00
Anders Carlsson 09da3372b6 When dumping vtables, dump whether a virtual member function is pure or not.

Evan Cheng 993bd1b7da Test for 95961. 
llvm-svn: 95962
 2010-02-12 02:35:03 +00:00
Chris Lattner f7477e599f add a bunch of mod/rm encoding types for fixed mod/rm bytes. 
This will work better for the disassembler for modeling things
like lfence/monitor/vmcall etc.

Evan Cheng 67e45e1670 Test case for 95958. 
llvm-svn: 95959
 2010-02-12 02:02:23 +00:00
Chris Lattner 44ac89f517 revert r95949, it turns out that adding new prefixes is not a 
great solution for the disassembler, we'll go with "plan b".

Daniel Dunbar 692d06fb77 MC: Fix bug where trailing tied operands were forgotten; the X86 assembler 
matcher is now free of implicit operands!
 - Still need to clean up the code now that we don't to worry about implicit
   operands, and to make it a hard error if an instruction fails to specify all
   of its operands for some reason.

 2010-02-12 01:46:54 +00:00
Johnny Chen 905a2d7727 Added coprocessor Instructions CDP, CDP2, MCR, MCR2, MRC, MRC2, MCRR, MCRR2, 
MRRC, MRRc2.  For disassembly only.

Bob Wilson 0827e040e0 Add a new pass on machine instructions to optimize away PHI cycles that 
reduce down to a single value.  InstCombine already does this transformation
but DAG legalization may introduce new opportunities.  This has turned out to
be important for ARM where 64-bit values are split up during type legalization:
InstCombine is not able to remove the PHI cycles on the 64-bit values but
the separate 32-bit values can be optimized.  I measured the compile time 
impact of this (running llc on 176.gcc) and it was not significant.

 2010-02-12 01:30:21 +00:00
Daniel Dunbar d7e9212e2d X86: Fix definition for RCL/RCR.*m? operations -- they were getting represented 
with "tied memory operands", which is wrong.

llvm-svn: 95950
 2010-02-12 01:22:03 +00:00
Chris Lattner 336f9abb45 add another bit of space for new kinds of instruction prefixes. 
llvm-svn: 95949
 2010-02-12 01:15:16 +00:00
Nate Begeman c780af6471 Add a missing pattern for movhps so that we get: 
movq	(%ecx,%edx,2), %xmm2
movhps	(%ecx,%eax,2), %xmm2

rather than:

movq     (%eax, %edx, 2), %xmm2		
movq     (%eax, %ebx, 2), %xmm3		
movlhps  %xmm3, %xmm2			

Testcase forthcoming.

Chris Lattner 1572e760bc fix the encodings of monitor and mwait, which were completely 
busted in both encoders.  I'm not bothering to fix it in the
old one at this point.

Chris Lattner 62f50dad8d improve support for minix, PR6280, patch by 
Kees van Reeuwijk!

llvm-svn: 95946
 2010-02-12 00:37:46 +00:00
Charles Davis be5557e86b Add a new function attribute, 'alignstack'. It will indicate (when the backends 
implement support for it) that the stack should be forcibly realigned in the
prologue (and the process reversed in the epilogue).

Ted Kremenek e9711db487 Two changes to scan-build: 
(1) When no 'clang' is found with 'scan-build', remember the one from
the path as scan-build sees it, not the build system.  This prevents
us from finding different clangs during the build.

(2) Don't set LDPLUSPLUS when running xcodebuild; instead rely on the
clang driver to do the right thing.

Tanya Lattner 90073804fb Implementing unused function warning. 
llvm-svn: 95940
 2010-02-12 00:07:30 +00:00
Charles Davis a90f7ca591 Warn about using the new force_align_arg_pointer attribute on a function 
pointer. If you don't like the new warning, you can turn it off with
-Wno-force-align-arg-pointer.

Jakob Stoklund Olesen 93c92225af Reapply coalescer fix for better cross-class coalescing. 
This time with fixed test cases.

llvm-svn: 95938
 2010-02-11 23:55:29 +00:00
Fariborz Jahanian 4c4ca5a9d3 Fixes a rewriting bug where order of constructor expression arguments did not match 
order of constructor arguments (all block API specific). This was exposed only in 
a large block literal expression in a large file where PtrSet container size 
execceded its limit and required reallocation.  Fixes radar 7638294

 2010-02-11 23:35:57 +00:00
Chris Lattner b1913c4df9 enhance llvm-mc -show-inst to print the enum of an instruction, like so: 
testb	%al, %al                ## <MCInst #2412 TEST8rr
                                        ##   <MCOperand Reg:2>
                                        ##   <MCOperand Reg:2>>
	jne	LBB1_7                  ## <MCInst #938 JNE_1
                                        ##   <MCOperand Expr:(LBB1_7)>>

Douglas Gregor 50dc219e8b When we have a dependent direct initializer but not a dependent 
variable type, we can (and should) still check for completeness of the
variable's type. Do so, to work around an assertion that shows up in
Boost's shared_ptr.

Ted Kremenek 9d6eb40ce7 Fix leak in CXXNewExpr where the SubExprs array would get allocated directly using 'new[]' instead of the allocator associated with ASTContext. 
llvm-svn: 95933
 2010-02-11 22:51:03 +00:00
John McCall 81472e34b2 Make this test not rely on the system <limits.h>. Hopefully fixes the 
MSVC build.

llvm-svn: 95932
 2010-02-11 22:45:16 +00:00
Ted Kremenek 9c8a6f5a8e Fix re-allocation in AttrWithString::ReplaceString() to use the allocator assosciated with ASTContext. 
llvm-svn: 95931
 2010-02-11 22:44:22 +00:00
Ted Kremenek 2c809308ca Allocate the SubExprs array in ObjCMessageExpr using the allocator associated with ASTContext. This fixes yet another leak (<rdar://problem/7639260>). 
llvm-svn: 95930
 2010-02-11 22:41:21 +00:00
Chris Lattner 524138176d add a new MCInstPrinter::getOpcodeName interface, when it is 
implemented, llvm-mc --show-inst now uses it to print the
instruction opcode as well as the number.

Chris Lattner b8af65ed0b improve encoding information for branches. We now know they have 
8 or 32-bit immediates, which allows the new encoder to handle
them.

llvm-svn: 95925
 2010-02-11 21:29:29 +00:00
Chris Lattner ddeceae839 make getFixupKindInfo return a const reference, allowing 
the tables to be const.  Teach MCCodeEmitter to handle
the target-indep kinds so that we don't crash on them.

Jakob Stoklund Olesen 28139f0043 It is always good to do a cross-class join when the large register has a tiny interval. 
Also avoid division by zero.
