* Convert the uses of '|&' to use '2>&1 |' instead, which works on oldChandler Carruth2012-07-021-1/+1
| | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159544 91177308-0d34-0410-b5e6-96231b3b80d8
* Convert all tests using TCL-style quoting to use shell-style quoting.Chandler Carruth2012-07-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | This was done through the aid of a terrible Perl creation. I will not paste any of the horrors here. Suffice to say, it require multiple staged rounds of replacements, state carried between, and a few nested-construct-parsing hacks that I'm not proud of. It happens, by luck, to be able to deal with all the TCL-quoting patterns in evidence in the LLVM test suite. If anyone is maintaining large out-of-tree test trees, feel free to poke me and I'll send you the steps I used to convert things, as well as answer any painful questions etc. IRC works best for this type of thing I find. Once converted, switch the LLVM lit config to use ShTests the same as Clang. In addition to being able to delete large amounts of Python code from 'lit', this will also simplify the entire test suite and some of lit's architecture. Finally, the test suite runs 33% faster on Linux now. ;] For my 16-hardware-thread (2x 4-core xeon e5520): 36s -> 24s git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159525 91177308-0d34-0410-b5e6-96231b3b80d8

* Use a bigger hammer to fix PR11314 by disabling the "forcing two-addressEvan Cheng2011-11-101-1/+1
| | | | | | | | | | | | | | | | | instruction lower optimization" in the pre-RA scheduler. The optimization, rather the hack, was done before MI use-list was available. Now we should be able to implement it in a better way, perhaps in the two-address pass until a MI scheduler is available. Now that the scheduler has to backtrack to handle call sequences. Adding artificial scheduling constraints is just not safe. Furthermore, the hack is not taking all the other scheduling decisions into consideration so it's just as likely to pessimize code. So I view disabling this optimization goodness regardless of PR11314. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@144267 91177308-0d34-0410-b5e6-96231b3b80d8

* Re-implement the main strength-reduction portion of LoopStrengthReduction.Dan Gohman2010-01-211-2/+2
| | | | | | | | | | | | | | | This new version is much more aggressive about doing "full" reduction in cases where it reduces register pressure, and also more aggressive about rewriting induction variables to count down (or up) to zero when doing so reduces register pressure. It currently uses fairly simplistic algorithms for finding reuse opportunities, but it introduces a new framework allows it to combine multiple strategies at once to form hybrid solutions, instead of doing all full-reduction or all base+index. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94061 91177308-0d34-0410-b5e6-96231b3b80d8
