* doc/invoke.texi: Use correct names/markup for "GCC", "GDB", "ld",
and related program names.
From-SVN: r185168
* Make-lang.in (convert.o): Depend on convert.h.
* convert.c: Header and comment cleanups.
(gfc_thruthvalue_conversion): Rename static function
to truthvalue_conversion. Do not use 'internal_error' from here,
use 'gcc_unreachable' instead.
(convert): Do not use 'error' for conversions to void, use
'gcc_unreachable' instead. Likewise for conversions to non-scalar
types. Do not hanlde ENUMERAL_TYPE, the front end never creates them.
Clean up #if 0 code.

* src/powerpc/aix_closure.S (ffi_closure_ASM): Adjust for Darwin64
change to return value of ffi_closure_helper_DARWIN and load type
from return type.

* config/rs6000/linux64.h (OPTION_TARGET_CPU_DEFAULT): Do not
redefine to be NULL if the current bit-size is different from the
configured bit-size.
* config/rs6000/rs6000.c (rs6000_option_override_internal): If the
cpu is defaulted, use PROCESSOR_DEFAULT and PROCESSOR_DEFAULT64 to
set the default tuning. Add asserts to make sure the cpu and tune
indexes are defined. Fix tests for cpu/tune index to use >= 0 to
test whether the index is set, instead of > 0.
(rs6000_file_start): Do not reset the default cpu if the current
bit-size is different from the configured bit-size.

* s-taskin.adb (Initialize_ATCB): Set Task_Image_Len to
0 so that we never access this field uninitialized (e.g. in
Task_Primitives.Operations.Enter_Task for the environment task).

* exp_ch5.adb (Expand_Iterator_Loop):
Call to Expand_Iterator_Loop_Over_Array added.

* a-direct.adb: Do not strip the trailing directory separator
from path, as this is already done inside Normalize_Pathname;
doing it again produces the wrong result on Windows for the
drive's root dir (i.e. "X:\" becomes "X:").

Name_Scalar_Storage_Order and Attribute_Scalar_Storage_Order.
(Sem_Ch13.Analyze_Attribute_Definition_Clause): Add processing

(Freeze): If Scalar_Storage_Order is specified, check that it
is compatible with Bit_Order.

* sem_ch6.adb (Check_Body_To_Inline): In AAMP and VM targets
use frontend inlining at all optimization levels.
* sem_util.adb (Must_Inline): In AAMP and VM targets, given that
there is no inlining support in the backend, use also frontend
inlining when compiling with optimizations enabled.

'else' and use standard name.

change obsolete idioms. Do not call above function.
