This will make it easier to turn on struct-path aware TBAA since the metadata
format will change.

Revert the test moves from 176733. Use "REQUIRES: asserts" instead.2013-03-12T16:27:52ZJan Wen Voungjvoung@google.com2013-03-12T16:27:52Zurn:sha1:4323665bd857c0527b50463d415d9e76493ad2fe

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.

Use references to attribute groups on the call/invoke instructions.2013-02-22T09:09:42ZBill Wendlingisanbard@gmail.com2013-02-22T09:09:42Zurn:sha1:351b7a10e2560a835759748c58da09e53207b39d
Listing all of the attributes for the callee of a call/invoke instruction is way
too much and makes the IR unreadable. Use references to attributes instead.

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).

Convert the uses of '|&' to use '2>&1 |' instead, which works on old2012-07-02T18:37:59ZChandler Carruthchandlerc@gmail.com2012-07-02T18:37:59Zurn:sha1:49589f0d0e35f643e697ab7ae8a51a530d38b0d8
versions of Bash. In addition, I can back out the change to the lit
built-in shell test runner to support this.
This should fix the majority of fallout on Darwin, but I suspect there
will be a few straggling issues.

Enable the new LoopInfo algorithm by default.2012-06-26T04:11:38ZAndrew Trickatrick@apple.com2012-06-26T04:11:38Zurn:sha1:c9b1e25493b393013b28e5d457f2fb2845a4dd9f
The primary advantage is that loop optimizations will be applied in a
stable order. This helps debugging and unit test creation. It is also
a better overall implementation without pathologically bad performance
on deep functions.
On large functions (llvm-stress --size=200000 | opt -loops)
Before: 0.1263s
After: 0.0225s
On deep functions (after tweaking llvm-stress, thanks Nadav):
Before: 0.2281s
After: 0.0227s
See r158790 for more comments.
The loop tree is now consistently generated in forward order, but loop
passes are applied in reverse order over the program. If we have a
loop optimization that prefers forward order, that can easily be
achieved by adding a different type of LoopPassManager.
