(alpha_cannot_fetch_register): Ditto. (alpha_cannot_store_register): Ditto. (alpha_register_convertible): Ditto. (alpha_use_struct_convention): Ditto. * config/alpha/tm-alpha.h: Update copyright years. (IN_SIGTRAMP): Use alpha_osf_in_sigtramp. (INNER_THAN): Use core_addr_lessthan. (CANNOT_FETCH_REGISTER): Use alpha_cannot_fetch_register. (CANNOT_STORE_REGISTER): Use alpha_cannot_store_register. (REGISTER_CONVERTIBLE): Use alpha_register_convertible. (USE_STRUCT_CONVENTION): Use alpha_use_struct_convention. (FRAME_CHAIN): Remove unnecessary cast. --- gdb/ChangeLog | 16 ++++++++++++++++ gdb/alpha-tdep.c | 30 ++++++++++++++++++++++++++++++ gdb/config/alpha/tm-alpha.h | 23 +++++++++++++++-------- 3 files changed, 61 insertions(+), 8 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index bc4b4fbde4d..15f5b59b005 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,19 @@ +2002-01-18 Jason Thorpe + + * alpha-tdep.c (alpha_osf_in_sigtramp): New function. + (alpha_cannot_fetch_register): Ditto. + (alpha_cannot_store_register): Ditto. + (alpha_register_convertible): Ditto. + (alpha_use_struct_convention): Ditto. + * config/alpha/tm-alpha.h: Update copyright years. + (IN_SIGTRAMP): Use alpha_osf_in_sigtramp. + (INNER_THAN): Use core_addr_lessthan. + (CANNOT_FETCH_REGISTER): Use alpha_cannot_fetch_register. + (CANNOT_STORE_REGISTER): Use alpha_cannot_store_register. + (REGISTER_CONVERTIBLE): Use alpha_register_convertible. + (USE_STRUCT_CONVENTION): Use alpha_use_struct_convention. + (FRAME_CHAIN): Remove unnecessary cast. + 2002-01-18 Andrew Cagney * NEWS: Document that testsuite/gdb.hp/gdb.threads-hp/ is diff --git a/gdb/alpha-tdep.c b/gdb/alpha-tdep.c index 0ec3add597a..a50000ede8c 100644 --- a/gdb/alpha-tdep.c +++ b/gdb/alpha-tdep.c @@ -144,6 +144,11 @@ struct linked_proc_info } *linked_proc_desc_table = NULL; +int +alpha_osf_in_sigtramp (CORE_ADDR pc, char *func_name) +{ + return (func_name != NULL && STREQ ("__sigtramp", func_name)); +} /* Under GNU/Linux, signal handler invocations can be identified by the designated code sequence that is used to return from a signal @@ -283,6 +288,24 @@ alpha_register_name (int regno) return (NULL); return (register_names[regno]); } + +int +alpha_cannot_fetch_register (int regno) +{ + return (regno == FP_REGNUM || regno == ZERO_REGNUM); +} + +int +alpha_cannot_store_register (int regno) +{ + return (regno == FP_REGNUM || regno == ZERO_REGNUM); +} + +int +alpha_register_convertible (int regno) +{ + return (regno >= FP0_REGNUM && regno <= FP0_REGNUM + 31); +} /* Guaranteed to set frame->saved_regs to some values (it never leaves it @@ -1410,6 +1433,13 @@ alpha_call_dummy_address (void) return SYMBOL_VALUE_ADDRESS (sym) + 4; } +int +alpha_use_struct_convention (int gcc_p, struct type *type) +{ + /* Structures are returned by ref in extra arg0. */ + return 1; +} + /* alpha_software_single_step() is called just before we want to resume the inferior, if we want to single-step it but there is no hardware or kernel single-step support (NetBSD on Alpha, for example).
