Disable statistics on Release builds and move tests that depend on -stats.2013-03-08T22:56:31ZJan Wen Voungjvoung@google.com2013-03-08T22:56:31Zurn:sha1:fa785cb22d50c657eb08c762d627cd6aa96982f3
Summary:
Statistics are still available in Release+Asserts (any +Asserts builds),
and stats can also be turned on with LLVM_ENABLE_STATS.
Move some of the FastISel stats that were moved under DEBUG()
back out of DEBUG(), since stats are disabled across the board now.
Many tests depend on grepping "-stats" output. Move those into
a orig_dir/Stats/. so that they can be marked as unsupported
when building without statistics.

Add a new attribute, 'noduplicate'. If a function contains a noduplicate call, the call cannot be duplicated - Jump threading, loop unrolling, loop unswitching, and loop rotation are inhibited if they would duplicate the call.2012-12-20T16:04:27ZJames Molloyjames.molloy@arm.com2012-12-20T16:04:27Zurn:sha1:67ae13575900e8efd056672987249fd0adbf5e73
Similarly inlining of the function is inhibited, if that would duplicate the call (in particular inlining is still allowed when there is only one callsite and the function has internal linkage).

getSmallConstantTripMultiple should never return zero.2012-10-24T19:46:44ZHal Finkelhfinkel@anl.gov2012-10-24T19:46:44Zurn:sha1:8c65549318950ff3fc1cb3d7a73fb50c688c78a5
When the trip count is -1, getSmallConstantTripMultiple could return zero,
and this would cause runtime loop unrolling to assert. Instead of returning
zero, one is now returned (consistent with the existing overflow cases).
Fixes PR14167.

Fix 12513: Loop unrolling breaks with indirect branches.2012-04-10T05:14:42ZAndrew Trickatrick@apple.com2012-04-10T05:14:42Zurn:sha1:d9fc1ce8096f7138c60edc3a6655583bf209780e
Take this opportunity to generalize the indirectbr bailout logic for
loop transformations. CFG transformations will never get indirectbr
right, and there's no point trying.

Add -unroll-runtime for unrolling loops with run-time trip counts.2011-12-09T06:19:40ZAndrew Trickatrick@apple.com2011-12-09T06:19:40Zurn:sha1:5d73448bb7f3d326f310e6f35030821b103b1cdb
Patch by Brendon Cahoon!
This extends the existing LoopUnroll and LoopUnrollPass. Brendon
measured no regressions in the llvm test suite with -unroll-runtime
enabled. This implementation works by using the existing loop
unrolling code to unroll the loop by a power-of-two (default 8). It
generates an if-then-else sequence of code prior to the loop to
execute the extra iterations before entering the unrolled loop.
