1. Added a status note when a config file is loaded directly with load_config. This helps notice loads of lit.cfg from lit.site.cfg
2. Added a status note on the result of a config load. Previously, it was just notifying that it tries to load a config file. Now it will also say whether the load succeeded or the file wasn't found

Teach GlobalOpt to handle atomic accesses to globals.

 * Most of the transforms come through intact by having each transformed load or
store copy the ordering and synchronization scope of the original.
 * The transform that turns a global only accessed in main() into an alloca
(since main is non-recursive) with a store of the initial value uses an
unordered store, since it's guaranteed to be the first thing to happen in main.
(Threads may have started before main (!) but they can't have the address of a
function local before the point in the entry block we insert our code.)
 * The heap-SRoA transforms are disabled in the face of atomic operations. This
can probably be improved; it seems odd to have atomic accesses to an alloca
that doesn't have its address taken.

AnalyzeGlobal keeps track of the strongest ordering found in any use of the
global. This is more information than we need right now, but it's cheap to

12 years agoReduce the number of dom queries made by GVN's conditional propagation
Duncan Sands [Sun, 5 Feb 2012 18:25:50 +0000 (18:25 +0000)]
Reduce the number of dom queries made by GVN's conditional propagation
logic by half: isOnlyReachableViaThisEdge was trying to be clever and
handle the case of a branch to a basic block which is contained in a
loop.  This costs a domtree lookup and is completely useless due to
GVN's position in the pass pipeline: all loops have preheaders at this
point, which means it is enough for isOnlyReachableViaThisEdge to check
that Dst has only one predecessor.  (I checked this theoretical argument
by running over the entire nightly testsuite, and indeed it is so!).
