Nick Lewycky 292e78c3cd When removing a function from the function set and adding it to deferred, we 
could end up removing a different function than we intended because it was
functionally equivalent, then end up with a comparison of a function against
itself in the next round of comparisons (the one in the function set and the
one on the deferred list). To fix this, I introduce a choice in the form of
comparison for ComparableFunctions, either normal or "pointer only" used to
find exact Function*'s in lookups.

Also add some debugging statements.

NAKAMURA Takumi f214f50739 Add testing stuff to CMake documents. 
- Note "GnuWin32".
  - Note LLVM_LIT_TOOLS_DIR
  - Now we can run tests on VS w/e all tests might pass or not!

NAKAMURA Takumi 0627147d12 test/lit.cfg: Seek sane tools(and bash) in directories and set to $PATH. 
LitConfig.getBashPath() will not seek in $PATH after LitConfig.getToolsPath() was executed.

llvm-svn: 125176
 2011-02-09 04:19:21 +00:00
NAKAMURA Takumi edfec9d04b lit/LitConfig.py: Add the new method getToolsPath(dir,paths,tools). 
It seeks tools(eg. [cmp, grep, sed]) in same directory, to be sane.

It seeks "bash" only in the directory found at last time. Or bash would be insane (against other tools).

llvm-svn: 125175
 2011-02-09 04:19:15 +00:00
NAKAMURA Takumi b5c0b4667e lit/Util.py: Add two functions, checkToolsPath(dir,tools) and whichTools(tools,paths). 
checkToolsPath(dir,tools):
return True if "dir" contains all "tools".

whichTools(tools,paths):
return a directory that contains all "tools" in "paths".
Or return None when all "tools" were not met.

NAKAMURA Takumi 189111808e lib/Support/Errno.cpp: Check strerror_s() with HAVE_DECL_STRERROR_S in config.h.*. 
AC_CHECK_FUNCS seeks a symbol only in libs. We should check the declaration in string.h.

FIXME: I have never seen mingw(s) have strerror_s() (not _strerror_s()).
FIXME: Autoconf/CMake may seek strerror_s() with the definition MINGW_HAS_SECURE_API in future.

Douglas Gregor 2575631c0f When IRgen refers to a function declaration that is not a definition, 
and we later find the definition, make sure that we add the definition
(not the declaration) to the list of deferred definitions to
emit. Fixes PR8864.

Ted Kremenek a40f8ebc83 static analyzer: Further reduce the analyzer's memory usage when analyzing sqlite3 by 7-10% by recylcing "uninteresting" ExplodedNodes. 
The optimization involves eagerly pruning ExplodedNodes from the ExplodedGraph that contain
practically no difference between the predecessor and successor nodes.  For example, if
the state is different between a predecessor and a node, the node is left in.  Only for
the 'environment' component of the state do we not care if the ExplodedNodes are different.
This paves the way for future optimizations where we can reclaim the environment objects.

Jakob Stoklund Olesen 1305bc0a65 Evict a lighter single interference before attempting to split a live range. 
Registers are not allocated strictly in spill weight order when live range
splitting and spilling has created new shorter intervals with higher spill
weights.

When one of the new heavy intervals conflicts with a single lighter interval,
simply evict the old interval instead of trying to split the heavy one.

The lighter interval is a better candidate for splitting, it has a smaller use
density.

Owen Anderson 4ebf471c9b Revert both r121082 (which broke a bunch of constant pool stuff) and r125074 (which worked around it). This should get us back to the old, correct behavior, though it will make the integrated assembler unhappy for the time being.
