* Change the fast-isel-abort option from bool to int to enable "levels"Mehdi Amini2015-02-271-2/+2
| | | | | | | | | | | | | | | | | | | | | | | Summary: Currently fast-isel-abort will only abort for regular instructions, and just warn for function calls, terminators, function arguments. There is already fast-isel-abort-args but nothing for calls and terminators. This change turns the fast-isel-abort options into an integer option, so that multiple levels of strictness can be defined. This will help no being surprised when the "abort" option indeed does not abort, and enables the possibility to write test that verifies that no intrinsics are forgotten by fast-isel.

* [FastISel][X86] Lower unsupported selects to control-flow.Juergen Ributzka2014-06-231-0/+138
The extends the select lowering coverage by emiting pseudo cmov instructions. These insturction will be later on lowered to control-flow to simulate the select. llvm-svn: 211545
