-; Windows and mingw require a prologue helper routine if more than 4096 bytes area
-; allocated on the stack.  Windows uses __chkstk and mingw uses __alloca.  __alloca
-; and the 32-bit version of __chkstk will probe the stack and adjust the stack pointer.
-; The 64-bit version of __chkstk is only responsible for probing the stack.  The 64-bit
-; prologue is responsible for adjusting the stack pointer.
-
-; Stack allocation >= 4096 bytes will require call to __chkstk in the Windows ABI.
