Description Martin Nowack 2010-11-04 09:16:10 UTC 
Created attachment 22272 [details]
mark _ITM_cxa_throw and _ITM_cxa_allocate_exception as tm_callable

Both calls are inserted into the code when coping with exceptions but are not marked as transaction_safe therefore abort the compilation.

Attached patch should fix that.
Comment 1 Patrick Marlier 2010-11-25 09:39:10 UTC 
I think these functions should be marked as transaction_pure and not transaction_safe since they are managed by the TM library.
