New Revision: 199706
URL: http://llvm.org/viewvc/llvm-project?rev=199706&view=rev
Log:
ARM IAS: support .personalityindex
The .personalityindex directive is equivalent to the .personality directive with
the ARM EABI personality with the specific index (0, 1, 2). Both of these
directives indicate personality routines, so enhance the personality directive
handling to take into account personalityindex.
Bonus fix: flush the UnwindContext at the beginning of a new function.
Thanks to Logan Chien for additional tests!
