+ * doc/invoke.texi (Option Summary, optimizations): Remove
+ -fbounds-check. Add -fassociative-math, -freciprocal-math,
+ -ftree-vrp and -funit-at-a-time. Change -fno-split-wide-types to
+ -fsplit-wide-types to match later entry. Break up a long line.
+ (Option Summary, code gen options) Add -fno-stack-limit. Add
+ missing @gol to the end of a line.
+ (Optimization Options): Remove -fbounds-check, which is also
+ documented under Code Generation Options. Remove =n from
+ index entry for -ftree-parallelize-loops. Change -fno-cprop-registers
+ to -fcprop-registers to match other options, and say when it is
+ enabled rather than disabled. Remove extra index entry for
+ -fno-cx-limited-range. Add index entries for -fstack-protector
+ and -fstack-protector-all.
+ (Code Gen Options): Add index entry for -ftls-model.

Parallelize loops, i.e., split their iteration space to run in n threads.
This is only possible for loops whose iterations are independent
and can be arbitrarily reordered. The optimization is only
This option is not supported for Fortran programs.

and occasionally eliminate the copy.

When enabled, this option states that a range reduction step is not
needed when performing complex division. The default is

@item -fstack-protector
+@opindex fstack-protector
Emit extra code to check for buffer overflows, such as stack smashing
attacks. This is done by adding a guard variable to functions with
vulnerable objects. This includes functions that call alloca, and
If a guard check fails, an error message is printed and the program exits.
@item -fstack-protector-all
+@opindex fstack-protector-all
Like @option{-fstack-protector} except that all functions are protected.
@item -fsection-anchors
Not all targets provide complete support for this switch.
@item -ftls-model=@var{model}
+@opindex ftls-model
Alter the thread-local storage model to be used (@pxref{Thread-Local}).
The @var{model} argument should be one of @code{global-dynamic},
@code{local-dynamic}, @code{initial-exec} or @code{local-exec}.
