* i386: Update preferred stack boundary for leaf functionshjl/pr82166/gcc-7-branchhjl2017-09-172-5/+26

* i386: Avoid stack realignment if possiblehjl2017-09-105-50/+136
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ix86_finalize_stack_frame_flags has been extended to eliminate frame pointer when the new stack frame isn't needed with and without -maccumulate-outgoing-args as well as -fomit-frame-pointer. Since stack access with larger alignment may be optimized out, to decide if stack realignment is needed, we need to not only check for stack frame access, but also verify the alignment of stack frame access. Since alignment of memory access via arg_pointer is set up by caller, not by callee, we should find the maximum stack alignment from the stack frame access instructions via stack pointer and frame pointrer to avoid stack realignment when stack alignment needed is less than incoming stack boundary. gcc/ PR target/59501 PR target/81624 PR target/81769 * config/i386/i386.c (ix86_finalize_stack_realign_flags): Don't realign stack if stack alignment needed is less than incoming stack boundary. gcc/testsuite/ PR target/59501 PR target/81624 PR target/81769 * gcc.target/i386/pr59501-4a.c: Remove xfail. * gcc.target/i386/pr81769-1a.c: New test. * gcc.target/i386/pr81769-1b.c: Likewise. * gcc.target/i386/pr81769-2.c: Likewise.

* [PR79542][Ada] Fix ICE in dwarf2out.c with nested func. inliningpmderodat2017-09-055-57/+149
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a backport from trunk. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79542 reports an ICE in dwarf2out.c for an Ada testcase built with optimization. This crash happens during the late generation pass because add_gnat_descriptive_type cannot find the type DIE corresponding to some descriptive type after having tried to generate it. This is because the DIE was generated during the early generation pass, but then pruned by the type pruning machinery. So why was it pruned? We are in a situation where we have cloned types (because of inlining, IIUC) whose TYPE_NAME have non-null DECL_ABSTRACT_ORIGIN attributes. As a consequence: * In modified_type_die, the "handle C typedef types" part calls gen_type_die on the cloned type. * gen_type_die matches a typedef variant, and then calls gen_decl_die on its TYPE_NAME, which will end up calling gen_typedef_die. * gen_typedef_die checks decl_ultimate_origin for this TYPE_DECL, and finds one, so it only adds a DW_AT_abstract_origin attribute to the DW_TAG_typedef DIE, but the cloned type itself does not get its own DIE. * Back in modified_type_die, the call to lookup_type_die on the type passed to gen_type_die returns NULL. In the end, whole type trees, i.e. the ones referenced by DECL_ABSTRACT_ORIGIN attributes, are never referenced from type pruning "roots" and are thus pruned. The descriptive type at stake here is one of them, hence the assertion failure. This patch attemps to fix that with what seems to be the most sensible thing to do in my opinion: updating the "handle C typedef types" part in modified_type_die to check decl_ultimate_origin before calling gen_type_die: if that function returns something not null, then we know that gen_type_die/gen_typedef_die will not generate a DIE for the input type, so we try to process the ultimate origin instead. It also updates in a similar way gen_type_die_with_usage, assert that when gen_typedef_die is called on nodes that have an ultimate origin, this origin is themselves. gcc/ PR ada/79542 * dwarf2out.c (modified_type_die): For C typedef types that have an ultimate origin, process the ultimate origin instead of the input type. (gen_typedef_die): Assert that input DECLs have no ultimate origin. (gen_type_die_with_usage): For typedef variants that have an ultimate origin, just call gen_decl_die on the original DECL.
