Note that to make this macro affect the alignment of stack
locals, a fix was required, and special precautions when handling
- the stack pointer in various other macros (FUNCTION_PROLOGUE et al)
- were required. See file "function.c". If you would just define
+ the stack pointer in various other macros (TARGET_ASM_FUNCTION_PROLOGUE

this macro, it would only affect the builtin alloca and variable
local data (non-ANSI, non-K&R, Gnu C extension). */
