2016-07-18Allocate constant size dynamic stack space in the prologueDominik Vogt8-84/+225
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. gcc/ChangeLog: 2016-07-18 Dominik Vogt <vogt@linux.vnet.ibm.com> * cfgexpand.c (expand_stack_vars): Implement synamic stack space allocation in the prologue. * explow.c (get_dynamic_stack_base): New function to return an address expression for the dynamic stack base.
