* Under normal circumstances, when a frame pointer is not required, we reserveEvan Cheng2007-05-011-17/+14
| | | | | | | | | | | | | argument space for call sites in the function immediately on entry to the current function. This eliminates the need for add/sub sp brackets around call sites. However, this is not always a good idea. If the "call frame" is large and the target load / store instructions have small immediate field to encode sp offset, this can cause poor codegen. In the worst case, this can make it impossible to scavenge a register if the reserved spill slot is pushed too far apart from sp / fp. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@36607 91177308-0d34-0410-b5e6-96231b3b80d8
