The PR was only fixed on i386, the same error was also reported on aarch64. This function, because it is sometimes called even outside of function bodies, uses create_tmp_var_raw rather than create_tmp_var. But in order for that to work, when first referenced, the VAR_DECLs need to appear in a TARGET_EXPR so that during gimplification the var gets the right DECL_CONTEXT and is added to local decls. Without that, e.g. tree-nested.c ICEs on those. 2020-04-29 Haijian Zhang PR target/94820 * config/aarch64/aarch64-builtins.c (aarch64_atomic_assign_expand_fenv): Use TARGET_EXPR instead of MODIFY_EXPR for first assignment to fenv_cr, fenv_sr and new_fenv_var. --- diff --git a/gcc/ChangeLog b/gcc/ChangeLog index 3df46e498f5..93d509710b7 100644 --- a/gcc/ChangeLog +++ b/gcc/ChangeLog @@ -1,3 +1,11 @@ +2020-04-29 Haijian Zhang + + PR target/94820 + * config/aarch64/aarch64-builtins.c + (aarch64_atomic_assign_expand_fenv): Use TARGET_EXPR instead of + MODIFY_EXPR for first assignment to fenv_cr, fenv_sr and + new_fenv_var. + 2020-04-29 Thomas Schwinge * configure.ac <$enable_offload_targets>: Do parsing as done diff --git a/gcc/config/aarch64/aarch64-builtins.c b/gcc/config/aarch64/aarch64-builtins.c index 5744e68ea08..95213cd70c8 100644 --- a/gcc/config/aarch64/aarch64-builtins.c +++ b/gcc/config/aarch64/aarch64-builtins.c @@ -2313,10 +2313,12 @@ aarch64_atomic_assign_expand_fenv (tree *hold, tree *clear, tree *update) mask_sr = build_int_cst (unsigned_type_node, ~(AARCH64_FE_ALL_EXCEPT)); - ld_fenv_cr = build2 (MODIFY_EXPR, unsigned_type_node, - fenv_cr, build_call_expr (get_fpcr, 0)); - ld_fenv_sr = build2 (MODIFY_EXPR, unsigned_type_node, - fenv_sr, build_call_expr (get_fpsr, 0)); + ld_fenv_cr = build4 (TARGET_EXPR, unsigned_type_node, + fenv_cr, build_call_expr (get_fpcr, 0), + NULL_TREE, NULL_TREE); + ld_fenv_sr = build4 (TARGET_EXPR, unsigned_type_node, + fenv_sr, build_call_expr (get_fpsr, 0), + NULL_TREE, NULL_TREE); masked_fenv_cr = build2 (BIT_AND_EXPR, unsigned_type_node, fenv_cr, mask_cr); masked_fenv_sr = build2 (BIT_AND_EXPR, unsigned_type_node, fenv_sr, mask_sr); @@ -2348,8 +2350,9 @@ aarch64_atomic_assign_expand_fenv (tree *hold, tree *clear, tree *update) __atomic_feraiseexcept (new_fenv_var); */ new_fenv_var = create_tmp_var_raw (unsigned_type_node); - reload_fenv = build2 (MODIFY_EXPR, unsigned_type_node, - new_fenv_var, build_call_expr (get_fpsr, 0)); + reload_fenv = build4 (TARGET_EXPR, unsigned_type_node, + new_fenv_var, build_call_expr (get_fpsr, 0), + NULL_TREE, NULL_TREE); restore_fnenv = build_call_expr (set_fpsr, 1, fenv_sr); atomic_feraiseexcept = builtin_decl_implicit (BUILT_IN_ATOMIC_FERAISEEXCEPT); update_call = build_call_expr (atomic_feraiseexcept, 1,
