Eli Friedman 1f4f9ddee8 The value of a case statement is a potentially evaluated context. Found by inspection.

Anna Zaks 7f6a6b7507 [analyzer] Refactor: prePropagateTaint -> 
TaintPropagationRule::process().

Also remove the "should be a pointer argument" warning - should be
handled elsewhere.

Anna Zaks 560dbe9ac9 [analyzer] Taint: warn when tainted data is used to specify a buffer 
size (Ex: in malloc, memcpy, strncpy..)

(Maybe some of this could migrate to the CString checker. One issue
with that is that we might want to separate security issues from
regular API misuse.)

Jim Grosbach adcc938c46 Thumb2 load/store fixups don't set the thumb bit. 
Load/store instructions w/ a fixup to be relative a function marked as thumb
don't use the low bit to specify thumb vs. non-thumb like interworking
branches do, so don't set it when dealing with those fixups.

Jakob Stoklund Olesen f43b599550 Add a CoveredBySubRegs property to Register descriptions. 
When set, this bit indicates that a register is completely defined by
the value of its sub-registers.

Use the CoveredBySubRegs property to infer which super-registers are
call-preserved given a list of callee-saved registers.  For example, the
ARM registers D8-D15 are callee-saved.  This now automatically implies
that Q4-Q7 are call-preserved.

Conversely, Win64 callees save XMM6-XMM15, but the corresponding
YMM6-YMM15 registers are not call-preserved because they are not fully
defined by their sub-registers.

Jim Grosbach 3fa6dcfebb Fix MCJIT memory leak of owned TargetMachine. 
The JIT is expected to take ownership of the TM that's passed in. The MCJIT
wasn't freeing it, resulting in leaks.

Sebastian Redl 43144e72b5 Template argument deduction for std::initializer_list arguments from initializer lists. 
llvm-svn: 148352
 2012-01-17 22:49:58 +00:00
Sebastian Redl fb0b1f1f1f Rename the first of 11 DeduceTemplateArguments overloads. 
There are 5 functions of this name in Sema, and 6 more static helpers in
SemaTemplateDeduction.cpp. The Sema functions have jobs like "deduce for
function call", "deduce for taking the address", etc. The static helpers
have jobs like "deduce by comparing two types", "deduce by comparing two
lists of types", "deduce by comparing two template arguments", etc.
The fact that they all are called the same and only differ in two of their
6 or more arguments makes the code using them very hard to read.

Here I rename the one function that concerns me most at the moment, but
as a matter of cleanup, the others will eventually be renamed as well.

Jakob Stoklund Olesen c3abb0f64a Add TableGen support for callee saved registers. 
Targets can now add CalleeSavedRegs defs to their *CallingConv.td file.
TableGen will use this to create a *_SaveList array suitable for
returning from getCalleeSavedRegs() as well as a *_RegMask bit mask
suitable for returning from getCallPreservedMask().

Jim Grosbach 4045507fea MC tweak symbol difference resolution for non-local symbols. 
When the non-local symbol in the expression is in the same fragment
as the second symbol, the assembler can still evaluate the expression
without needing a relocation.

For example, on ARM:
_foo:
	ldr lr, (_foo - 4)
