    • Allocate constant size dynamic stack space in the prologue · 7072df0a 
      The attached patch fixes a warning during Linux kernel compilation
on S/390 due to -mwarn-dynamicstack and runtime alignment of stack
variables with constant size causing cfun->calls_alloca to be set
(even if alloca is not used at all).  The patched code places
constant size runtime aligned variables in the "virtual stack
vars" area instead of creating a "virtual stack dynamic" area.

This behaviour is activated by defining

  #define ALLOCATE_DYNAMIC_STACK_SPACE_IN_PROLOGUE 1

in the backend; otherwise the old logic is used.

The kernel uses runtime alignment for the page structure (aligned
to 16 bytes), and apart from triggereing the alloca warning
(-mwarn-dynamicstack), the current Gcc also generates inefficient
code like

  aghi %r15,-160  # prologue: create stack frame
    lgr %r11,%r15   # prologue: generate frame pointer
      aghi %r15,-32   # space for dynamic stack

which could be simplified to

  aghi %r15,-192

(if later optimization passes are able to get rid of the frame
pointer).  Is there a specific reason why the patched behaviour
shouldn't be used for all platforms?

--

As the placement of runtime aligned stack variables with constant
size is done completely in the middleend, I don't see a way to fix
this in the backend.
