Bug ID: 111135 Summary: Add ECF_MALLOC for BUILT_IN_GOMP_ALLOC Product: gcc Version: 14.0 Status: UNCONFIRMED Keywords: missed-optimization Severity: normal Priority: P3 Component: fortran Assignee: unassigned at gcc dot gnu.org Reporter: burnus at gcc dot gnu.org Target Milestone: --- The Fortran side is all in gcc/fortran/f95-lang.cc It seems as if ECF_MALLOC should be added to ATTR_ALLOC_WARN_UNUSED_RESULT_SIZE_2_NOTHROW_LIST to match both builtin-attrs.def; that macro is used for: BUILT_IN_ALIGNED_ALLOC BUILT_IN_GOMP_ALLOC (I find the builtin-attrs.def file not very readable.) I do note that f95-lang.cc has: DECL_IS_MALLOC (builtin_decl_explicit (BUILT_IN_CALLOC)) = 1; while builtins.def uses ATTR_MALLOC_WARN_UNUSED_RESULT_SIZE_1_2_NOTHROW_LEAF_LIST for it. Thus, setting DECL_IS_MALLOC for GOMP_ALLOC explicitly would work as well (ALIGNED_ALLOC is not (yet) used in the Fortran FE.) BTW: The ECF_MALLOC causes DECL_IS_MALLOC to be set via tree.cc's set_call_expr_flags.
