2020-05-14Make anti_adjust_stack_and_probe_stack_clash extern and use it for ZAndreas Krebbel
When compiling with -mbackchain -fstack-clash-protection currently no probes are emitted. This patch adjusts the "allocate_stack" expander to call anti_adjust_stack_and_probe_stack_clash when needed. In order to do this I had to export that function from explow.c. Ok for mainline? gcc/ChangeLog: 2020-05-14 Andreas Krebbel <krebbel@linux.ibm.com> * config/s390/s390.md ("allocate_stack"): Call anti_adjust_stack_and_probe_stack_clash when stack clash protection is enabled. * explow.c (anti_adjust_stack_and_probe_stack_clash): Remove prototype. Remove static. * explow.h (anti_adjust_stack_and_probe_stack_clash): Add prototype. gcc/testsuite/ChangeLog: 2020-05-14 Andreas Krebbel <krebbel@linux.ibm.com> * gcc.target/s390/stack-clash-3.c: New test.

2018-11-21[PATCH][PR84877]Dynamically align the address for local parameter copy on ↵Renlin Li
the stack when required alignment is larger than MAX_SUPPORTED_STACK_ALIGNMENT As described in PR84877. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=84877 The local copy of parameter on stack is not aligned. For BLKmode paramters, a local copy on the stack will be saved. There are three cases: 1) arguments passed partially on the stack, partially via registers. 2) arguments passed fully on the stack. 3) arguments passed via registers. After the change here, in all three cases, the stack slot for the local parameter copy is aligned by the data type. The stack slot is the DECL_RTL of the parameter. All the references thereafter in the function will refer to this RTL. To populate the local copy on the stack, For case 1) and 2), there are operations to move data from the caller's stack (from incoming rtl) into callee's stack. For case 3), the registers are directly saved into the stack slot. In all cases, the destination address is properly aligned. But for case 1) and case 2), the source address is not aligned by the type. It is defined by the PCS how the arguments are prepared. The block move operation is fulfilled by emit_block_move (). As far as I can see, it will use the smaller alignment of source and destination. This looks fine as long as we don't use instructions which requires a strict larger alignment than the address actually has. Here, it only changes receiving parameters. The function assign_stack_local_1 will be called in various places. Usually, the caller will constraint the ALIGN parameter. For example via STACK_SLOT_ALIGNMENT macro. assign_parm_setup_block will call assign_stack_local () with alignment from the parameter type which in this case could be larger than MAX_SUPPORTED_STACK_ALIGNMENT. The alignment operation for parameter copy on the stack is similar to stack vars. First, enough space is reserved on the stack. The size is fixed at compile time. Instructions are emitted to dynamically get an aligned address at runtime within this piece of memory. This will unavoidably increase the usage of stack. However, it really depends on how many over-aligned parameters are passed by value. gcc/ 2018-11-21 Renlin Li <renlin.li@arm.com> PR middle-end/84877 * explow.h (get_dynamic_stack_size): Declare it as external. * explow.c (record_new_stack_level): Remove function static attribute. * function.c (assign_stack_local_1): Dynamically align the stack slot addr for parameter copy on the stack. gcc/testsuite/ 2018-11-21 Renlin Li <renlin.li@arm.com> PR middle-end/84877 * gcc.dg/pr84877.c: New.

2016-07-18Allocate constant size dynamic stack space in the prologueDominik Vogt
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.
