12 years agoExtend Attributes to 64 bits
Kostya Serebryany [Fri, 20 Jan 2012 17:56:17 +0000 (17:56 +0000)]
Extend Attributes to 64 bits

Problem: LLVM needs more function attributes than currently available (32 bits).
One such proposed attribute is "address_safety", which shows that a function is being checked for address safety (by AddressSanitizer, SAFECode, etc).

Solution:
- extend the Attributes from 32 bits to 64-bits
- wrap the object into a class so that unsigned is never erroneously used instead
- change "unsigned" to "Attributes" throughout the code, including one place in clang.
- the class has no "operator uint64 ()", but it has "uint64_t Raw() " to support packing/unpacking.
- the class has "safe operator bool()" to support the common idiom:  if (Attributes attr = getAttrs()) useAttrs(attr);
- The CTOR from uint64_t is marked explicit, so I had to add a few explicit CTOR calls
- Add the new attribute "address_safety". Doing it in the same commit to check that attributes beyond first 32 bits actually work.
- Some of the functions from the Attribute namespace are worth moving inside the class, but I'd prefer to have it as a separate commit.

Tested:
"make check" on Linux (32-bit and 64-bit) and Mac (10.6)
built/run spec CPU 2006 on Linux with clang -O2.

This change will break clang build in lib/CodeGen/CGCall.cpp.

Add an LLDB data formatter script for llvm::SmallVector, maybe this is helpful to someone else.

This lets lldb give sane output for SmallVectors, e.g.
Before:
(lldb) p sv
(llvm::SmallVector<int, 10>) $0 = {
  (llvm::SmallVectorImpl<int>) llvm::SmallVectorImpl<int> = {
    (llvm::SmallVectorTemplateBase<int>) llvm::SmallVectorTemplateBase<int> = {
      (llvm::SmallVectorTemplateCommon<int>) llvm::SmallVectorTemplateCommon<int> = {
        (llvm::SmallVectorBase) llvm::SmallVectorBase = {
          (void *) BeginX = 0x00007fff5fbff960
...
}

After:
(lldb) p sv
(llvm::SmallVector<int, 10>) $0 = {
  (int) [0] = 42
  (int) [1] = 23
...
}

The script is still a bit rough so expect crashes for vectors of complex types.
Synthetic children are _not_ available in xcode 4.2, newer LLDBs should work though.

Fix 11769.

In CanXFormVExtractWithShuffleIntoLoad we assumed that EXTRACT_VECTOR_ELT can be later handled by the DAGCombiner.
However, in some cases on AVX, the EXTRACT_VECTOR_ELT is legalized to EXTRACT_SUBVECTOR + EXTRACT_VECTOR_ELT, which
currently is not handled by the DAGCombiner. In this patch I added a check that we only extract from the XMM part.
