Duncan P. N. Exon Smith [Fri, 25 Mar 2016 14:40:18 +0000 (14:40 +0000)]
Bitcode: Collect all MDString records into a single blob

Optimize output of MDStrings in bitcode.  This emits them in big blocks
(currently 1024) in a pair of records:
  - BULK_STRING_SIZES: the sizes of the strings in the block, and
  - BULK_STRING_DATA: a single blob, which is the concatenation of all
    the strings.

Inspired by Mehdi's similar patch, http://reviews.llvm.org/D18342, this
should (a) slightly reduce bitcode size, since there is less record
overhead, and (b) greatly improve reading speed, since blobs are super
cheap to deserialize.

I needed to add support for blobs to streaming input to get the test
suite passing.
  - StreamingMemoryObject::getPointer reads ahead and returns the
    address of the blob.
  - To avoid a possible reallocation of StreamingMemoryObject::Bytes,
    BitstreamCursor::readRecord needs to move the call to JumpToEnd
    forward so that getPointer is the last bitstream operation.

Add utility script to generate checks for opt or llc regression tests

the IR checking more flexible.

violated all best practices of Python programming if I've made a functional

wrong, please let me know or feel free to fix it. I didn't even read any
documentation...

The good news:
I tested this on ~10 existing opt/llc regression tests, and it does what
I hoped for. It produces exact checking for IR regression tests and doesn't
signficantly change the existing llc-with-x86-target asm checking. The opt
tests that were modified in r263667, r263668, r263674, and r263679 are
examples of the expected results, except that this version of the script
puts the check lines ahead of the IR to follow the existing llc/asm
behavior.

If there are no complaints/fallout, we should be able to remove the
original script. Extending this script to be used for non-x86 and clang

[asan] Intercept all Heap* related imports from ucrtbase.dll

ucrtbase.dll appears to be built with some kind of cross-module
inlining, because there are calls to imported Heap* routines sprinkled
throughout the code. This inlining defeats our attempts to hotpatch
malloc, _malloc_base, and related functions. Failing to intercept an
allocation or deallocation results in a crash when the program attempts
to deallocate or reallocate memory with the wrong allocator.

This change patches the IAT of ucrtbase.dll to replace the addresses of
the imported Heap* functions with implementations provided by ASan.  We
don't globally intercept the win32 Heap* functions because they are
typically used by system DLLs that run before ASan initializes.
Eventually, we may want to intercept them, but for now I think this is

doesn't help the user identify the problem.

When no intermediate DWP files are generated, the path to the two DWO
files could be provided - but is lost once the DWOs are merged into a
DWP.

So, include the name of the DWO (dwo_name) in the split file so that
collissions involving a source CU from a DWP can be better diagnosed.

8 years ago[LLE] Check for mismatching types between the store and the load earlier
Adam Nemet [Thu, 24 Mar 2016 17:59:26 +0000 (17:59 +0000)]
[LLE] Check for mismatching types between the store and the load earlier

isDependenceDistanceOfOne asserts that the store and the load access
through the same type.  This function is also used by
removeDependencesFromMultipleStores so we need to make sure we filter
out mismatching types before reaching this point.

Now we do this when the initial candidates are gathered.

This is a refinement of the fix made in r262267.

Fixes PR27048.
