Check for stack space more intelligently. libgcc sets the stack limit field in TCB to 256 bytes above the actual allocated stack limit. This means if the function's stack frame needs less than 256 bytes, we can just compare the stack pointer with the stack limit. This should result in lesser calls to __morestack. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145766 91177308-0d34-0410-b5e6-96231b3b80d8

Check for stack space more intelligently. libgcc sets the stack limit field in TCB to 256 bytes above the actual allocated stack limit. This means if the function's stack frame needs less than 256 bytes, we can just compare the stack pointer with the stack limit. This should result in lesser calls to __morestack. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145766 91177308-0d34-0410-b5e6-96231b3b80d8
