# 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.
