* Make the JIT default to the DAG isel instead of the pattern isel, like LLC.Chris Lattner2005-09-291-1/+4
| | | | | | | | | | The Pattern isel has some strange memory corruption issues going on. :( This should have been converted over anyway, but it got forgotten somehow when switching to the dag isel. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23523 91177308-0d34-0410-b5e6-96231b3b80d8

* Darwin, like many BSD systems, has a setjmp/longjmp which saves the signal maskChris Lattner2005-09-271-0/+3
| | | | | | | | | | on setjmp calls and restores it on longjmp calls (both of which require syscalls). This makes the calls REALLY slow. Use _setjmp/_longjmp instead. This speeds up hexxagon from 120.31s to 15.68s: from 5.53x slower than GCC to 28% faster than GCC. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23482 91177308-0d34-0410-b5e6-96231b3b80d8

This fixes the scheduler from causing problems by moving a copyfromreg for an argument to after a select_cc node (now it can, and bad things won't happen). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23334 91177308-0d34-0410-b5e6-96231b3b80d8
