Need to define MISSING_BLOCKS_SUPPORT in this case at buildtime.

Patch by Jack Howarth <howarth@bromo.med.uc.edu>
 

llvm-svn: 169206

Add the ability to get a symbol or symbols by name and type from a SBModule, and also the ability to get all symbols by name and type from SBTarget objects.

ASan: add new interface functions - __asan_(un)poison_stack_memory. Calls to these functions are inserted by the instrumentation pass in use-after-scope mode

llvm-svn: 169201

ASan: add initial support for handling llvm.lifetime intrinsics in ASan - emit calls into runtime library that poison memory for local variables when their lifetime is over and unpoison memory when their lifetime begins.

the alignment is clamped to TargetFrameLowering.getStackAlignment if the target
does not support stack realignment or the option "realign-stack" is off.

This will cause miscompile if the address is treated as aligned and add is
replaced with or in DAGCombine.

Added a bool StackRealignable to TargetFrameLowering to check whether stack
realignment is implemented for the target. Also added a bool RealignOption
to MachineFrameInfo to check whether the option "realign-stack" is on.

These functions have been replaced by TRI::getRegAllocationHints() which
provides the same capabilities.

Have clang use LLVM IR's fast-math flags when in FastMath or FiniteMathOnly modes. Test cases included.

llvm-svn: 169191

Now that there can be multiple hint registers from targets, it doesn't
make sense to have a function that returns 'the' preferred register.

llvm-svn: 169190

Cleaned up the option parsing code to always pass around the short options as integers. Previously we cast this down to "char" and lost some information. I recently added an assert that would detect duplicate short character options which was firing during the test suite.

This fix does the following:
- make sure all short options are treated as "int"
- make sure that short options can be non-printable values when a short option is not required or when an option group is mixed into many commands and a short option is not desired
- fix the help printing to "do the right thing" in all cases. Previously if there were duplicate short character options, it would just not emit help for the duplicates
- fix option parsing when there are duplicates to parse options correctly. Previously the option parsing, when done for an OptionGroup, would just start parsing options incorrectly by omitting table entries and it would end up setting the wrong option value

llvm-svn: 169189

Targets can provide multiple hints now, so getRegAllocPref() doesn't
make sense any longer because it only returns one preferred register.
Replace it with getSimpleHint() in the remaining heuristics. This
function only

No functional change for this commit. The follow-up patch will add more stuff to
these functions.

- use const char* instead of char* as needed in ObjC language runtime plugin
- use int to iterate through enum (operator++ on enum not defined)
- use initializer list instead of inline initialization of const field

 This change tries to simmplify E1 = " X >> C1 << C2" into :
  - E2 = "X << (C2 - C1)" if C2 > C1, or
  - E2 = "X >> (C1 - C2)" if C1 > C2, or
  - E2 = X if C1 == C2.

Virtual registers with a known preferred register are prioritized by
RAGreedy. This function makes the condition explicit without depending
on getRegAllocPref().

This small change adds support for that. It will make all MCJIT tests pass
in make-check on BigEndian platforms.

This change adds endian-awareness to MipsJITInfo and emitWordLE in
MipsCodeEmitter has become emitWord now to support both endianness.

This simplifies the hinting code quite a bit while making the targets
easier to write at the same time.

This provides the same functionality as getRawAllocationOrder() for the
even/odd hints, but without the many constant register arrays.
