* Fix eabi calling convention when a 64 bit value shadows r3.Rafael Espindola2010-08-061-0/+14
| | | | | | | | | | | Without this what was happening was: * R3 is not marked as "used" * ARM backend thinks it has to save it to the stack because of vaarg * Offset computation correctly ignores it * Offsets are wrong git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@110446 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix memdep's code for reasoning about dependences between two calls. A RefDan Gohman2010-08-051-1/+0
| | | | | | | | | | | response from getModRefInfo is not useful here. Instead, check for identical calls only in the NoModRef case. Reapply r110270, and strengthen it to compensate for the memdep changes.
