-@section @code{.bundle_align_mode @var{abs-expr}}
+@section Bundle directives
+@subsection @code{.bundle_align_mode @var{abs-expr}}
@cindex @code{bundle_align_mode} directive
@cindex bundle
@cindex instruction bundle
starts in the next bundle. As a corollary, it's an error if any single
instruction's encoding is longer than the bundle size.
-@section @code{.bundle_lock} and @code{.bundle_unlock}
+@subsection @code{.bundle_lock} and @code{.bundle_unlock}
@cindex @code{bundle_lock} directive
@cindex @code{bundle_unlock} directive
The @code{.bundle_lock} and directive @code{.bundle_unlock} directives
Each expression is assembled into the next byte.
@node CFI directives
-@section @code{.cfi_sections @var{section_list}}
+@section CFI directives
+@subsection @code{.cfi_sections @var{section_list}}
@cindex @code{cfi_sections} directive
@code{.cfi_sections} may be used to specify whether CFI directives
should emit @code{.eh_frame} section and/or @code{.debug_frame} section.
To emit both use @code{.eh_frame, .debug_frame}. The default if this
directive is not used is @code{.cfi_sections .eh_frame}.
-@section @code{.cfi_startproc [simple]}
+@subsection @code{.cfi_startproc [simple]}
@cindex @code{cfi_startproc} directive
@code{.cfi_startproc} is used at the beginning of each function that
should have an entry in @code{.eh_frame}. It initializes some internal
Unless @code{.cfi_startproc} is used along with parameter @code{simple}
it also emits some architecture dependent initial CFI instructions.
-@section @code{.cfi_endproc}
+@subsection @code{.cfi_endproc}
@cindex @code{cfi_endproc} directive
@code{.cfi_endproc} is used at the end of a function where it closes its
unwind entry previously opened by
@code{.cfi_startproc}, and emits it to @code{.eh_frame}.
-@section @code{.cfi_personality @var{encoding} [, @var{exp}]}
+@subsection @code{.cfi_personality @var{encoding} [, @var{exp}]}
@code{.cfi_personality} defines personality routine and its encoding.
@var{encoding} must be a constant determining how the personality
should be encoded. If it is 255 (@code{DW_EH_PE_omit}), second
The default after @code{.cfi_startproc} is @code{.cfi_personality 0xff},
no personality routine.
-@section @code{.cfi_lsda @var{encoding} [, @var{exp}]}
+@subsection @code{.cfi_lsda @var{encoding} [, @var{exp}]}
@code{.cfi_lsda} defines LSDA and its encoding.
@var{encoding} must be a constant determining how the LSDA
should be encoded. If it is 255 (@code{DW_EH_PE_omit}), second
or a symbol name. The default after @code{.cfi_startproc} is @code{.cfi_lsda 0xff},
no LSDA.
-@section @code{.cfi_def_cfa @var{register}, @var{offset}}
+@subsection @code{.cfi_def_cfa @var{register}, @var{offset}}
@code{.cfi_def_cfa} defines a rule for computing CFA as: @i{take
address from @var{register} and add @var{offset} to it}.
-@section @code{.cfi_def_cfa_register @var{register}}
+@subsection @code{.cfi_def_cfa_register @var{register}}
@code{.cfi_def_cfa_register} modifies a rule for computing CFA. From
now on @var{register} will be used instead of the old one. Offset
remains the same.
-@section @code{.cfi_def_cfa_offset @var{offset}}
+@subsection @code{.cfi_def_cfa_offset @var{offset}}
@code{.cfi_def_cfa_offset} modifies a rule for computing CFA. Register
remains the same, but @var{offset} is new. Note that it is the
absolute offset that will be added to a defined register to compute
CFA address.
-@section @code{.cfi_adjust_cfa_offset @var{offset}}
+@subsection @code{.cfi_adjust_cfa_offset @var{offset}}
Same as @code{.cfi_def_cfa_offset} but @var{offset} is a relative
value that is added/substracted from the previous offset.
-@section @code{.cfi_offset @var{register}, @var{offset}}
+@subsection @code{.cfi_offset @var{register}, @var{offset}}
Previous value of @var{register} is saved at offset @var{offset} from
CFA.
-@section @code{.cfi_rel_offset @var{register}, @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}
using the known displacement of the CFA register from the CFA.
This is often easier to use, because the number will match the
code it's annotating.
-@section @code{.cfi_register @var{register1}, @var{register2}}
+@subsection @code{.cfi_register @var{register1}, @var{register2}}
Previous value of @var{register1} is saved in register @var{register2}.
-@section @code{.cfi_restore @var{register}}
+@subsection @code{.cfi_restore @var{register}}
@code{.cfi_restore} says that the rule for @var{register} is now the
same as it was at the beginning of the function, after all initial
instruction added by @code{.cfi_startproc} were executed.
-@section @code{.cfi_undefined @var{register}}
+@subsection @code{.cfi_undefined @var{register}}
From now on the previous value of @var{register} can't be restored anymore.
-@section @code{.cfi_same_value @var{register}}
+@subsection @code{.cfi_same_value @var{register}}
Current value of @var{register} is the same like in the previous frame,
i.e. no restoration needed.
-@section @code{.cfi_remember_state},
+@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.
-@section @code{.cfi_return_column @var{register}}
+@subsection @code{.cfi_return_column @var{register}}
Change return column @var{register}, i.e. the return address is either
directly in @var{register} or can be accessed by rules for @var{register}.
-@section @code{.cfi_signal_frame}
+@subsection @code{.cfi_signal_frame}
Mark current function as signal trampoline.
-@section @code{.cfi_window_save}
+@subsection @code{.cfi_window_save}
SPARC register window has been saved.
-@section @code{.cfi_escape} @var{expression}[, @dots{}]
+@subsection @code{.cfi_escape} @var{expression}[, @dots{}]
Allows the user to add arbitrary bytes to the unwind info. One
might use this to add OS-specific CFI opcodes, or generic CFI
opcodes that GAS does not yet support.
-@section @code{.cfi_val_encoded_addr @var{register}, @var{encoding}, @var{label}}
+@subsection @code{.cfi_val_encoded_addr @var{register}, @var{encoding}, @var{label}}
The current value of @var{register} is @var{label}. The value of @var{label}
will be encoded in the output file according to @var{encoding}; see the
description of @code{.cfi_personality} for details on this encoding.
