# MIPS/IRIX ISA/ABI
# Used to configure dwarfdump printing of .debug_frame and
# .eh_frame.
# Any number of abi's can be described. Only one can be selected
# in a given darfdump run (see dwarfdump options)
# Available commands are
# beginabi: <abiname>
# reg: <regname> <dwarf regnumber>
# frame_interface: <integer value 2 or 3>
# cfa_reg: <number>
# initial_reg_value: <number: normally 1034 or 1035 >
# reg_table_size: <size of table>
# endabi: <abiname>
#
# Symbolic names do not work here, use literal numbers
# where applicable (in C standard decimal, octal (leading 0) or
# hexadecimal <leading 0x>).
#
# Whitespace is required to separate command: from operands and
# operands from each other on a line.
#
# There is no ordering required within a beginabi/endabi pair.
# As many ABIs as required may be listed.
# dwarfdump will choose exactly one abi to dump frame information.
#
# Here using MIPS abi as an example to describe
# the format. The MIPS/IRIX ABI is built-in to dwarfdump, so this one
# is not really required.
# Begin with abi name (use here and on dwarfdump command line).
beginabi: mips
# Instructs dwarfdump to default to the older frame interface.
# Use value 3 to use the newer interface.
# The '2' interface is supported but deprecated (deprecated
# because it cannot work with all popular ABIs: mixing
# the cfa-rule into the table column set was not a good idea
# but it is part of the MIPS/IRIX standard usage).
frame_interface: 2
# If (and only if) using frame_interface: 2 tell dwarfdump
# what table colum that DW_FRAME_CFA_COL is.
# If using frame_interface: 3 cfa_reg: should be
# DW_FRAME_CFA_COL3 (1036)
cfa_reg: 0
# For MIPS, the same as DW_FRAME_SAME_VAL (1035).
# For other ISA/ABIs 1034 (DW_FRAME_UNDEFINED_VAL) might be better.
# Depends on the ABI convention, if set wrong way too many
# regs will be listed in the frame output.
# This instructs dwarfdump to set libdwarf to this value,
# overriding the libdwarf default.
# If initial_reg_value not set the libdwarf default is used
# (see libdwarf.h DW_FRAME_REG_INITIAL_VALUE).
initial_reg_value: 1035 # DW_FRAME_SAME_VAL
# Built in to frame_interface: 2 as 66.
reg_table_size: 66
# Only name registers for wich a r4 (for example) is not what you
# want to see
# No particular order of the reg: lines required.
