From 2b4424c35b9ebabaab8588b2ba6c38935a48efec Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Fri, 20 Apr 2018 11:50:09 -0600 Subject: Add initial type alignment support This adds some basic type alignment support to gdb. It changes struct type to store the alignment, and updates dwarf2read.c to handle DW_AT_alignment. It also adds a new gdbarch method and updates i386-tdep.c. None of this new functionality is used anywhere yet, so tests will wait until the next patch. 2018-04-30 Tom Tromey * i386-tdep.c (i386_type_align): New function. (i386_gdbarch_init): Update. * gdbarch.sh (type_align): New method. * gdbarch.c, gdbarch.h: Rebuild. * arch-utils.h (default_type_align): Declare. * arch-utils.c (default_type_align): New function. * gdbtypes.h (TYPE_ALIGN_BITS): New define. (struct type) : New field. : Now a bitfield. (TYPE_RAW_ALIGN): New macro. (type_align, type_raw_align, set_type_align): Declare. * gdbtypes.c (type_align, type_raw_align, set_type_align): New functions. * dwarf2read.c (quirk_rust_enum): Set type alignment. (get_alignment, maybe_set_alignment): New functions. (read_structure_type, read_enumeration_type, read_array_type) (read_set_type, read_tag_pointer_type, read_tag_reference_type) (read_subrange_type, read_base_type): Set type alignment. --- gdb/arch-utils.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'gdb/arch-utils.h') diff --git a/gdb/arch-utils.h b/gdb/arch-utils.h index b785b24..77ee9af 100644 --- a/gdb/arch-utils.h +++ b/gdb/arch-utils.h @@ -267,4 +267,8 @@ extern CORE_ADDR gdbarch_skip_prologue_noexcept (gdbarch *gdbarch, extern bool default_in_indirect_branch_thunk (gdbarch *gdbarch, CORE_ADDR pc); +/* Default implementation of gdbarch type_align method. */ +extern ULONGEST default_type_align (struct gdbarch *gdbarch, + struct type *type); + #endif -- cgit v1.1
