Refactor ppc64 function call and return value handling This patch refactors the ppc64 function call and return value handling code in ppc-sysv-tdep.c. The main problem to be addressed by this refactoring is the code duplication caused by certain aggregate types: According to the ABI, some types are to be decomposed into component types for parameter and return value handling. For example, complex types are to be passed as if the real and imaginary component were separate arguments. Similarly, certain OpenCL vector types are passed as if they were multiple separate arguments of the vector element type. With the new ELFv2 ABI, there is another case: "homogeneous aggregates" (e.g. a struct containing 4 floats) are passed in multiple floating point registers as well. Unfortunately, the current code is not structured to easily model these ABI properties. For example, code to pass complex values re-implements code to pass the underlying (floating-point) type. This has already led to some unfortunate code duplication, and with the addition of ELFv2 ABI support, I would have had to add yet more such duplication. To avoid that, I've decided to refactor the code in order to re-use subroutines that handle the "base" types when handling those aggregate types. This was not intended to cause any difference on current (ELFv1) ABI code, but in fact it fixes a bug: FAIL: gdb.base/varargs.exp: print find_max_float_real(4, fc1, fc2, fc3, fc4) This was caused by the old code in ppc64_sysv_abi_push_float incorrectly handling floating-point arguments to vararg routines, which just happens to work out correctly automatically in the refactored code ... gdb/ChangeLog: * ppc-sysv-tdep.c (get_decimal_float_return_value): Update comment.

Mostly trivial enum fixes This is a patch I extracted from Pedro's C++ branch. It contains the most trivial enum fixes, where an integer type/value was used instead of the appropriate enum type/value. It fixes many C++ errors, since in C++ you can't mix integers and enums implicitely. Regardless of the C++ conversion, I think this is a good cleanup to make use of the appropriate enum types. Regression-tested on native x86_64. gdb/ChangeLog: * aarch64-linux-nat.c (aarch64_linux_can_use_hw_breakpoint): Use enum type or value instead of integer. (aarch64_linux_insert_watchpoint): Likewise.

Convert lvalue reference type check to general reference type check In almost all contexts (except for overload resolution rules and expression semantics), lvalue and rvalue references are equivalent. That means that in all but these cases we can replace a TYPE_CODE_REF check to a TYPE_IS_REFERENCE check and, for switch statements, add a case label for a rvalue reference type next to a case label for an lvalue reference type.

use bound_minsym as result for lookup_minimal_symbol et al This patch changes a few minimal symbol lookup functions to return a bound_minimal_symbol rather than a pointer to the minsym. This change helps prepare gdb for computing a minimal symbol's address at the point of use. Note that this changes even those functions that ostensibly search a single objfile. That was necessary because, in fact, those functions can search an objfile and its separate debug objfiles; and it is important for the caller to know in which objfile the minimal symbol was actually found.

change minsym representation In a later patch we're going to change the minimal symbol address calculation to apply section offsets at the point of use. To make it simpler to catch potential problem spots, this patch changes the representation of minimal symbols and introduces new minimal-symbol-specific variants of the various accessors. This is necessary because it would be excessively ambitious to try to convert all the symbol types at once. The core of this change is just renaming a field in minimal_symbol; the rest is just a fairly mechanical rewording. 2014-02-26 Tom Tromey <tromey@redhat.com> * symtab.h (struct minimal_symbol) <mginfo>: Rename from ginfo.

change minsym representation In a later patch we're going to change the minimal symbol address calculation to apply section offsets at the point of use. To make it simpler to catch potential problem spots, this patch changes the representation of minimal symbols and introduces new minimal-symbol-specific variants of the various accessors. This is necessary because it would be excessively ambitious to try to convert all the symbol types at once. The core of this change is just renaming a field in minimal_symbol; the rest is just a fairly mechanical rewording. 2014-02-26 Tom Tromey <tromey@redhat.com> * symtab.h (struct minimal_symbol) <mginfo>: Rename from ginfo.

use bound_minsym as result for lookup_minimal_symbol et al This patch changes a few minimal symbol lookup functions to return a bound_minimal_symbol rather than a pointer to the minsym. This change helps prepare gdb for computing a minimal symbol's address at the point of use. Note that this changes even those functions that ostensibly search a single objfile. That was necessary because, in fact, those functions can search an objfile and its separate debug objfiles; and it is important for the caller to know in which objfile the minimal symbol was actually found.

start change to progspace independence This patch starts changing minimal symbols to be independent of the program space. Specifically, it adds a new objfile parameter to MSYMBOL_VALUE_ADDRESS and changes all the code to use it. This is needed so we can change gdb to apply the section offset when a minsym's address is computed, as opposed to baking the offsets into the symbol itself. A few spots still need the unrelocated address. For these, we introduce MSYMBOL_VALUE_RAW_ADDRESS. As a convenience, we also add the new macro BMSYMBOL_VALUE_ADDRESS, which computes the address of a bound minimal symbol. This just does the obvious thing with the fields. Note that this change does not actually enable program space independence. That requires more changes to gdb. However, to ensure that these changes compile properly, this patch does add the needed section lookup code to MSYMBOL_VALUE_ADDRESS -- it just ensures it has no effect at runtime by multiplying the offset by 0. 2014-02-26 Tom Tromey <tromey@redhat.com> * ada-lang.c (ada_main_name): Update.

Refactor ppc64 function call and return value handling This patch refactors the ppc64 function call and return value handling code in ppc-sysv-tdep.c. The main problem to be addressed by this refactoring is the code duplication caused by certain aggregate types: According to the ABI, some types are to be decomposed into component types for parameter and return value handling. For example, complex types are to be passed as if the real and imaginary component were separate arguments. Similarly, certain OpenCL vector types are passed as if they were multiple separate arguments of the vector element type. With the new ELFv2 ABI, there is another case: "homogeneous aggregates" (e.g. a struct containing 4 floats) are passed in multiple floating point registers as well. Unfortunately, the current code is not structured to easily model these ABI properties. For example, code to pass complex values re-implements code to pass the underlying (floating-point) type. This has already led to some unfortunate code duplication, and with the addition of ELFv2 ABI support, I would have had to add yet more such duplication. To avoid that, I've decided to refactor the code in order to re-use subroutines that handle the "base" types when handling those aggregate types. This was not intended to cause any difference on current (ELFv1) ABI code, but in fact it fixes a bug: FAIL: gdb.base/varargs.exp: print find_max_float_real(4, fc1, fc2, fc3, fc4) This was caused by the old code in ppc64_sysv_abi_push_float incorrectly handling floating-point arguments to vararg routines, which just happens to work out correctly automatically in the refactored code ... gdb/ChangeLog: * ppc-sysv-tdep.c (get_decimal_float_return_value): Update comment.

Convert lvalue reference type check to general reference type check In almost all contexts (except for overload resolution rules and expression semantics), lvalue and rvalue references are equivalent. That means that in all but these cases we can replace a TYPE_CODE_REF check to a TYPE_IS_REFERENCE check and, for switch statements, add a case label for a rvalue reference type next to a case label for an lvalue reference type. This patch does exactly that. gdb/ChangeLog PR gdb/14441 * aarch64-tdep.c (aarch64_type_align) (aarch64_extract_return_value, aarch64_store_return_value): Change lvalue reference type checks to general reference type checks. * amd64-tdep.c (amd64_classify): Likewise. * amd64-windows-tdep.c (amd64_windows_passed_by_integer_register): Likewise. * arm-tdep.c (arm_type_align, arm_extract_return_value) (arm_store_return_value): Likewise. * ax-gdb.c (gen_fetch, gen_cast): Likewise. * c-typeprint.c (c_print_type): Likewise. * c-varobj.c (adjust_value_for_child_access, c_value_of_variable) (cplus_number_of_children, cplus_describe_child): Likewise. * compile/compile-c-symbols.c (generate_vla_size): Likewise. * completer.c (expression_completer): Likewise. * cp-support.c (make_symbol_overload_list_adl_namespace): Likewise. * darwin-nat-info.c (info_mach_region_command): Likewise. * dwarf2loc.c (entry_data_value_coerce_ref) (value_of_dwarf_reg_entry): Likewise. * eval.c (ptrmath_type_p, evaluate_subexp_standard) (evaluate_subexp_for_address, evaluate_subexp_for_sizeof): Likewise. * findvar.c (extract_typed_address, store_typed_address): Likewise. * gdbtypes.c (rank_one_type): Likewise. * hppa-tdep.c (hppa64_integral_or_pointer_p): Likewise. * infcall.c (value_arg_coerce): Likewise. * language.c (pointer_type): Likewise. * m32c-tdep.c (m32c_reg_arg_type, m32c_m16c_address_to_pointer): Likewise. * m88k-tdep.c (m88k_integral_or_pointer_p): Likewise. * mn10300-tdep.c (mn10300_type_align): Likewise. * msp430-tdep.c (msp430_push_dummy_call): Likewise. * ppc-sysv-tdep.c (do_ppc_sysv_return_value) (ppc64_sysv_abi_push_param, ppc64_sysv_abi_return_value): Likewise. * printcmd.c (print_formatted, x_command): Likewise. * python/py-type.c (typy_get_composite, typy_template_argument): Likewise. * python/py-value.c (valpy_referenced_value) (valpy_get_dynamic_type, value_has_field): Likewise. * s390-linux-tdep.c (s390_function_arg_integer): Likewise. * sparc-tdep.c (sparc_integral_or_pointer_p): Likewise. * sparc64-tdep.c (sparc64_integral_or_pointer_p): Likewise. * spu-tdep.c (spu_scalar_value_p): Likewise. * symtab.c (lookup_symbol_aux): Likewise. * typeprint.c (whatis_exp, print_type_scalar): Likewise. * valarith.c (binop_types_user_defined_p, unop_user_defined_p): Likewise. * valops.c (value_cast_pointers, value_cast) (value_reinterpret_cast, value_dynamic_cast, value_addr, typecmp) (value_struct_elt, value_struct_elt_bitpos) (value_find_oload_method_list, find_overload_match) (value_rtti_indirect_type): Likewise. * valprint.c (val_print_scalar_type_p, generic_val_print): Likewise. * value.c (value_actual_type, value_as_address, unpack_long) (pack_long, pack_unsigned_long, coerce_ref_if_computed) (coerce_ref): Likewise. * varobj.c (varobj_get_value_type): Likewise.

Refactor ppc64 function call and return value handling This patch refactors the ppc64 function call and return value handling code in ppc-sysv-tdep.c. The main problem to be addressed by this refactoring is the code duplication caused by certain aggregate types: According to the ABI, some types are to be decomposed into component types for parameter and return value handling. For example, complex types are to be passed as if the real and imaginary component were separate arguments. Similarly, certain OpenCL vector types are passed as if they were multiple separate arguments of the vector element type. With the new ELFv2 ABI, there is another case: "homogeneous aggregates" (e.g. a struct containing 4 floats) are passed in multiple floating point registers as well. Unfortunately, the current code is not structured to easily model these ABI properties. For example, code to pass complex values re-implements code to pass the underlying (floating-point) type. This has already led to some unfortunate code duplication, and with the addition of ELFv2 ABI support, I would have had to add yet more such duplication. To avoid that, I've decided to refactor the code in order to re-use subroutines that handle the "base" types when handling those aggregate types. This was not intended to cause any difference on current (ELFv1) ABI code, but in fact it fixes a bug: FAIL: gdb.base/varargs.exp: print find_max_float_real(4, fc1, fc2, fc3, fc4) This was caused by the old code in ppc64_sysv_abi_push_float incorrectly handling floating-point arguments to vararg routines, which just happens to work out correctly automatically in the refactored code ... gdb/ChangeLog: * ppc-sysv-tdep.c (get_decimal_float_return_value): Update comment.

Refactor ppc64 function call and return value handling This patch refactors the ppc64 function call and return value handling code in ppc-sysv-tdep.c. The main problem to be addressed by this refactoring is the code duplication caused by certain aggregate types: According to the ABI, some types are to be decomposed into component types for parameter and return value handling. For example, complex types are to be passed as if the real and imaginary component were separate arguments. Similarly, certain OpenCL vector types are passed as if they were multiple separate arguments of the vector element type. With the new ELFv2 ABI, there is another case: "homogeneous aggregates" (e.g. a struct containing 4 floats) are passed in multiple floating point registers as well. Unfortunately, the current code is not structured to easily model these ABI properties. For example, code to pass complex values re-implements code to pass the underlying (floating-point) type. This has already led to some unfortunate code duplication, and with the addition of ELFv2 ABI support, I would have had to add yet more such duplication. To avoid that, I've decided to refactor the code in order to re-use subroutines that handle the "base" types when handling those aggregate types. This was not intended to cause any difference on current (ELFv1) ABI code, but in fact it fixes a bug: FAIL: gdb.base/varargs.exp: print find_max_float_real(4, fc1, fc2, fc3, fc4) This was caused by the old code in ppc64_sysv_abi_push_float incorrectly handling floating-point arguments to vararg routines, which just happens to work out correctly automatically in the refactored code ... gdb/ChangeLog: * ppc-sysv-tdep.c (get_decimal_float_return_value): Update comment.

Refactor ppc64 function call and return value handling This patch refactors the ppc64 function call and return value handling code in ppc-sysv-tdep.c. The main problem to be addressed by this refactoring is the code duplication caused by certain aggregate types: According to the ABI, some types are to be decomposed into component types for parameter and return value handling. For example, complex types are to be passed as if the real and imaginary component were separate arguments. Similarly, certain OpenCL vector types are passed as if they were multiple separate arguments of the vector element type. With the new ELFv2 ABI, there is another case: "homogeneous aggregates" (e.g. a struct containing 4 floats) are passed in multiple floating point registers as well. Unfortunately, the current code is not structured to easily model these ABI properties. For example, code to pass complex values re-implements code to pass the underlying (floating-point) type. This has already led to some unfortunate code duplication, and with the addition of ELFv2 ABI support, I would have had to add yet more such duplication. To avoid that, I've decided to refactor the code in order to re-use subroutines that handle the "base" types when handling those aggregate types. This was not intended to cause any difference on current (ELFv1) ABI code, but in fact it fixes a bug: FAIL: gdb.base/varargs.exp: print find_max_float_real(4, fc1, fc2, fc3, fc4) This was caused by the old code in ppc64_sysv_abi_push_float incorrectly handling floating-point arguments to vararg routines, which just happens to work out correctly automatically in the refactored code ... gdb/ChangeLog: * ppc-sysv-tdep.c (get_decimal_float_return_value): Update comment.

This was not intended to cause any difference on current (ELFv1) ABI code, but in fact it fixes a bug: FAIL: gdb.base/varargs.exp: print find_max_float_real(4, fc1, fc2, fc3, fc4) This was caused by the old code in ppc64_sysv_abi_push_float incorrectly handling floating-point arguments to vararg routines, which just happens to work out correctly automatically in the refactored code ... gdb/ChangeLog: * ppc-sysv-tdep.c (get_decimal_float_return_value): Update comment. (struct ppc64_sysv_argpos): New data structure. (ppc64_sysv_abi_push_float): Remove. (ppc64_sysv_abi_push_val): New function. (ppc64_sysv_abi_push_integer): Likewise.

Refactor ppc64 function call and return value handling This patch refactors the ppc64 function call and return value handling code in ppc-sysv-tdep.c. The main problem to be addressed by this refactoring is the code duplication caused by certain aggregate types: According to the ABI, some types are to be decomposed into component types for parameter and return value handling. For example, complex types are to be passed as if the real and imaginary component were separate arguments. Similarly, certain OpenCL vector types are passed as if they were multiple separate arguments of the vector element type. With the new ELFv2 ABI, there is another case: "homogeneous aggregates" (e.g. a struct containing 4 floats) are passed in multiple floating point registers as well. Unfortunately, the current code is not structured to easily model these ABI properties. For example, code to pass complex values re-implements code to pass the underlying (floating-point) type. This has already led to some unfortunate code duplication, and with the addition of ELFv2 ABI support, I would have had to add yet more such duplication. To avoid that, I've decided to refactor the code in order to re-use subroutines that handle the "base" types when handling those aggregate types. This was not intended to cause any difference on current (ELFv1) ABI code, but in fact it fixes a bug: FAIL: gdb.base/varargs.exp: print find_max_float_real(4, fc1, fc2, fc3, fc4) This was caused by the old code in ppc64_sysv_abi_push_float incorrectly handling floating-point arguments to vararg routines, which just happens to work out correctly automatically in the refactored code ... gdb/ChangeLog: * ppc-sysv-tdep.c (get_decimal_float_return_value): Update comment.

Refactor ppc64 function call and return value handling This patch refactors the ppc64 function call and return value handling code in ppc-sysv-tdep.c. The main problem to be addressed by this refactoring is the code duplication caused by certain aggregate types: According to the ABI, some types are to be decomposed into component types for parameter and return value handling. For example, complex types are to be passed as if the real and imaginary component were separate arguments. Similarly, certain OpenCL vector types are passed as if they were multiple separate arguments of the vector element type. With the new ELFv2 ABI, there is another case: "homogeneous aggregates" (e.g. a struct containing 4 floats) are passed in multiple floating point registers as well. Unfortunately, the current code is not structured to easily model these ABI properties. For example, code to pass complex values re-implements code to pass the underlying (floating-point) type. This has already led to some unfortunate code duplication, and with the addition of ELFv2 ABI support, I would have had to add yet more such duplication. To avoid that, I've decided to refactor the code in order to re-use subroutines that handle the "base" types when handling those aggregate types. This was not intended to cause any difference on current (ELFv1) ABI code, but in fact it fixes a bug: FAIL: gdb.base/varargs.exp: print find_max_float_real(4, fc1, fc2, fc3, fc4) This was caused by the old code in ppc64_sysv_abi_push_float incorrectly handling floating-point arguments to vararg routines, which just happens to work out correctly automatically in the refactored code ... gdb/ChangeLog: * ppc-sysv-tdep.c (get_decimal_float_return_value): Update comment.

Refactor ppc64 function call and return value handling This patch refactors the ppc64 function call and return value handling code in ppc-sysv-tdep.c. The main problem to be addressed by this refactoring is the code duplication caused by certain aggregate types: According to the ABI, some types are to be decomposed into component types for parameter and return value handling. For example, complex types are to be passed as if the real and imaginary component were separate arguments. Similarly, certain OpenCL vector types are passed as if they were multiple separate arguments of the vector element type. With the new ELFv2 ABI, there is another case: "homogeneous aggregates" (e.g. a struct containing 4 floats) are passed in multiple floating point registers as well. Unfortunately, the current code is not structured to easily model these ABI properties. For example, code to pass complex values re-implements code to pass the underlying (floating-point) type. This has already led to some unfortunate code duplication, and with the addition of ELFv2 ABI support, I would have had to add yet more such duplication. To avoid that, I've decided to refactor the code in order to re-use subroutines that handle the "base" types when handling those aggregate types. This was not intended to cause any difference on current (ELFv1) ABI code, but in fact it fixes a bug: FAIL: gdb.base/varargs.exp: print find_max_float_real(4, fc1, fc2, fc3, fc4) This was caused by the old code in ppc64_sysv_abi_push_float incorrectly handling floating-point arguments to vararg routines, which just happens to work out correctly automatically in the refactored code ... gdb/ChangeLog: * ppc-sysv-tdep.c (get_decimal_float_return_value): Update comment.

Refactor ppc64 function call and return value handling This patch refactors the ppc64 function call and return value handling code in ppc-sysv-tdep.c. The main problem to be addressed by this refactoring is the code duplication caused by certain aggregate types: According to the ABI, some types are to be decomposed into component types for parameter and return value handling. For example, complex types are to be passed as if the real and imaginary component were separate arguments. Similarly, certain OpenCL vector types are passed as if they were multiple separate arguments of the vector element type. With the new ELFv2 ABI, there is another case: "homogeneous aggregates" (e.g. a struct containing 4 floats) are passed in multiple floating point registers as well. Unfortunately, the current code is not structured to easily model these ABI properties. For example, code to pass complex values re-implements code to pass the underlying (floating-point) type. This has already led to some unfortunate code duplication, and with the addition of ELFv2 ABI support, I would have had to add yet more such duplication.

Refactor ppc64 function call and return value handling This patch refactors the ppc64 function call and return value handling code in ppc-sysv-tdep.c. The main problem to be addressed by this refactoring is the code duplication caused by certain aggregate types: According to the ABI, some types are to be decomposed into component types for parameter and return value handling. For example, complex types are to be passed as if the real and imaginary component were separate arguments. Similarly, certain OpenCL vector types are passed as if they were multiple separate arguments of the vector element type. With the new ELFv2 ABI, there is another case: "homogeneous aggregates" (e.g. a struct containing 4 floats) are passed in multiple floating point registers as well. Unfortunately, the current code is not structured to easily model these ABI properties. For example, code to pass complex values re-implements code to pass the underlying (floating-point) type. This has already led to some unfortunate code duplication, and with the addition of ELFv2 ABI support, I would have had to add yet more such duplication. To avoid that, I've decided to refactor the code in order to re-use subroutines that handle the "base" types when handling those aggregate types.
