* Make ARM an X86 memcpy expansion more similar to each other.Rafael Espindola2007-10-311-7/+5
| | | | | | | | | | Now both subtarget define getMaxInlineSizeThreshold and the expansion uses it. This should not change generated code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43552 91177308-0d34-0410-b5e6-96231b3b80d8
* Add support for having different alignment for objects on call frames.Rafael Espindola2007-09-071-1/+1
| | | | | | | | The x86-64 ABI states that objects passed on the stack have 8 byte alignment. Implement that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41768 91177308-0d34-0410-b5e6-96231b3b80d8

* Implement Subtarget supportNate Begeman2005-07-121-0/+55
Implement the X86 Subtarget. This consolidates the checks for target triple, and setting options based on target triple into one place. This allows us to convert the asm printer and isel over from being littered with "forDarwin", "forCygwin", etc. into just having the appropriate flags for each subtarget feature controlling the code for that feature. This patch also implements indirect external and weak references in the X86 pattern isel, for darwin. Next up is to convert over the asm printers to use this new interface. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22389 91177308-0d34-0410-b5e6-96231b3b80d8
