-value that is added/substracted from the previous offset.
+value that is added/subtracted from the previous offset.
@subsection @code{.cfi_offset @var{register}, @var{offset}}
Previous value of @var{register} is saved at offset @var{offset} from
CFA.
+@subsection @code{.cfi_val_offset @var{register}, @var{offset}}
+Previous value of @var{register} is CFA + @var{offset}.
+
@subsection @code{.cfi_rel_offset @var{register}, @var{offset}}
Previous value of @var{register} is saved at offset @var{offset} from
the current CFA register. This is transformed to @code{.cfi_offset}
Current value of @var{register} is the same like in the previous frame,
i.e. no restoration needed.
-@subsection @code{.cfi_remember_state},
-First save all current rules for all registers by @code{.cfi_remember_state},
-then totally screw them up by subsequent @code{.cfi_*} directives and when
-everything is hopelessly bad, use @code{.cfi_restore_state} to restore
-the previous saved state.
+@subsection @code{.cfi_remember_state} and @code{.cfi_restore_state}
+@code{.cfi_remember_state} pushes the set of rules for every register onto an
+implicit stack, while @code{.cfi_restore_state} pops them off the stack and
+places them in the current row. This is useful for situations where you have
+multiple @code{.cfi_*} directives that need to be undone due to the control
+flow of the program. For example, we could have something like this (assuming
+the CFA is the value of @code{rbp}):
+
+@smallexample
+ je label
+ popq %rbx
+ .cfi_restore %rbx
+ popq %r12
+ .cfi_restore %r12
+ popq %rbp
+ .cfi_restore %rbp
+ .cfi_def_cfa %rsp, 8
+ ret
+label:
+ /* Do something else */
+@end smallexample
+
+Here, we want the @code{.cfi} directives to affect only the rows corresponding
+to the instructions before @code{label}. This means we'd have to add multiple
+@code{.cfi} directives after @code{label} to recreate the original save
+locations of the registers, as well as setting the CFA back to the value of
+@code{rbp}. This would be clumsy, and result in a larger binary size. Instead,
+we can write:
+
+@smallexample
+ je label
+ popq %rbx
+ .cfi_remember_state
+ .cfi_restore %rbx
+ popq %r12
+ .cfi_restore %r12
+ popq %rbp
+ .cfi_restore %rbp
+ .cfi_def_cfa %rsp, 8
+ ret
+label:
+ .cfi_restore_state
+ /* Do something else */
+@end smallexample
+
+That way, the rules for the instructions after @code{label} will be the same
+as before the first @code{.cfi_restore} without having to use multiple
+@code{.cfi} directives.
@subsection @code{.cfi_return_column @var{register}}
Change return column @var{register}, i.e. the return address is either
@ifset Z80
The syntax for @code{equ} on the Z80 is

This directive will set the @code{discriminator} register in the @code{.debug_line}
state machine to @var{value}, which must be an unsigned integer.
+@item view @var{value}
+This option causes a row to be added to @code{.debug_line} in reference to the
+current address (which might not be the same as that of the following assembly
+instruction), and to associate @var{value} with the @code{view} register in the
+@code{.debug_line} state machine. If @var{value} is a label, both the
+@code{view} register and the label are set to the number of prior @code{.loc}
+directives at the same program location. If @var{value} is the literal
+@code{0}, the @code{view} register is set to zero, and the assembler asserts
+that there aren't any prior @code{.loc} directives at the same program
+location. If @var{value} is the literal @code{-0}, the assembler arrange for
+the @code{view} register to be reset in this row, even if there are prior
+@code{.loc} directives at the same program location.

combination of the following characters:
+
@table @code

+@item d

@item e

+@item @code{<target specific>}
+some targets extend this list with their own flag characters
@end table
+Note - once a section's flags have been set they cannot be changed. There are
+a few exceptions to this rule however. Processor and application specific
+flags can be added to an already defined section. The @code{.interp},
+@code{.strtab} and @code{.symtab} sections can have the allocate flag
+(@code{a}) set after they are initially defined, and the @code{.note-GNU-stack}
+section may have the executable (@code{x}) flag added.
+

+
@table @code

@item @@preinit_array

+Many targets only support the first three section types. The type may be

@code{%} character.
+Note - some sections, eg @code{.text} and @code{.data} are considered to be
+special and have fixed types. Any attempt to declare them with a different

+
If @var{flags} contains the @code{M} symbol then the @var{type} argument must
be specified as well as an extra argument---@var{entsize}---like this:
The @var{GroupName} field specifies the name of the section group to which this
particular section belongs. The optional linkage field can contain:
+
@table @code
@item comdat
indicates that only one copy of this section should be retained
Note that the section name is quoted. There may be a sequence of comma
separated flags:
