--- Comment #18 from Markus Trippelsdorf <trippels at gcc dot gnu.org> ---
Here is an example:
...
static const struct pt_regs_offset x86_32_regoffset_table[] = {
REG_OFFSET_NAME_32("%ax", eax),
REG_OFFSET_NAME_32("%cx", ecx),
REG_OFFSET_NAME_32("%dx", edx),
REG_OFFSET_NAME_32("%bx", ebx),
REG_OFFSET_NAME_32("$stack", esp), /* Stack address instead of %sp
*/
REG_OFFSET_NAME_32("%bp", ebp),
REG_OFFSET_NAME_32("%si", esi),
REG_OFFSET_NAME_32("%di", edi),
REG_OFFSET_END,
};
static const struct pt_regs_offset x86_64_regoffset_table[] = {
REG_OFFSET_NAME_64("%ax", rax),
REG_OFFSET_NAME_64("%dx", rdx),
REG_OFFSET_NAME_64("%cx", rcx),
REG_OFFSET_NAME_64("%bx", rbx),
REG_OFFSET_NAME_64("%si", rsi),
REG_OFFSET_NAME_64("%di", rdi),
REG_OFFSET_NAME_64("%bp", rbp),
REG_OFFSET_NAME_64("%sp", rsp),
REG_OFFSET_NAME_64("%r8", r8),
REG_OFFSET_NAME_64("%r9", r9),
REG_OFFSET_NAME_64("%r10", r10),
REG_OFFSET_NAME_64("%r11", r11),
REG_OFFSET_NAME_64("%r12", r12),
REG_OFFSET_NAME_64("%r13", r13),
REG_OFFSET_NAME_64("%r14", r14),
REG_OFFSET_NAME_64("%r15", r15),
REG_OFFSET_END,
};
/* TODO: switching by dwarf address size */
