New Revision: 284174<br>
<br>
URL: <a href="http://llvm.org/viewvc/llvm-project?rev=284174&view=rev" target="_blank">

Log:<br>
Disable swiftcall test on windows: More brutal way to appease windows bots<br>
<br>
The backtrace on the bot does not give me any indication what is wrong.<br>
The test case interestingly passes in stage2 of the build.<br>
I don't have a way of debugging this.<br>
<br>
Disable the test on windows and hope if there is truly a bug in the code that<br>
was causing we will eventually run into this on other platforms.<br>
