* stmt.c (expand_return): Ditto.
* stor-layout.c (compute_record_mode): If
FUNCTION_ARG_REG_LITTLE_ENDIAN is set then check
MEMBER_TYPE_FORCES_BLK even if mode == VOIDmode.
* config/ia64/hpux.h (MEMBER_TYPE_FORCES_BLK): Set to true
so that Structures of one field are still treated as structures.
(FUNCTION_ARG_REG_LITTLE_ENDIAN): New, set it to true.
(FUNCTION_ARG_PADDING): Set to ia64_hpux_function_arg_padding().
(PAD_VARARGS_DOWN): Modify from default to not pad structures down.

* freeze.adb: Make Freeze_Fixed_Point_Type visible, for use in
sem_attr.
* sem_attr.adb: Simplify previous fix for Address.
(Set_Bounds): If prefix is a non-frozen fixed-point type, freeze now,
to avoid anomalies where the bound of the type appears to raise
constraint error.
* lib-xref.adb (Output_Refs): Make sure pointers are always properly
handled.
* sem_ch12.adb (Analyze_Subprogram_Instantiation): Check for a
renamed unit before checking for recursive instantiations.
* prj.ads: Add comments for some of the fields.
From-SVN: r47902
* lib-xref.adb (Output_Refs): Don't output type references outside
the main unit if they are not otherwise referenced.
* sem_attr.adb (Analyze_attribute, case Address and Size): Simplify
code and diagnose additional illegal uses
* sem_util.adb (Is_Object_Reference): An indexed component is an
object only if the prefix is.
* g-diopit.adb: Initial version.
* g-diopit.ads: Initial version.
* g-dirope.adb:
(Expand_Path): Avoid use of Unbounded_String
(Find, Wildcard_Iterator): Moved to child package Iteration
* Makefile.in: Added g-diopit.o to GNATRTL_NONTASKING_OBJS
* sem_attr.adb: Minor reformatting

* sched-rgn.c (CONST_BASED_ADDRESS_P): CONST_INT -> CONSTANT_P.
(may_trap_exp): Stores only are risk if they trap, too, not just
if code == MEM.
From-SVN: r47900
* sem_ch3.adb: Clarify some ???.
* exp_util.adb (Must_Be_Aligned): Removed, replaced by
Exp_Pakd.Known_Aligned_Enough
* sem_ch13.adb (Check_Address_Alignment): Removed, extended
version is moved to Exp_Ch13.
From-SVN: r47899
* einfo.ads: Minor reformatting
* exp_ch5.adb: Add comment for previous.change
* ali.adb: New interface for extended typeref stuff.
* ali.ads: New interface for typeref stuff.
* checks.adb (Apply_Alignment_Check): New procedure.
* debug.adb: Add -gnatdM for modified ALI output
* exp_pakd.adb (Known_Aligned_Enough): Replaces Known_Aligned_Enough.
* lib-xref.adb: Extend generation of <..> notation to cover
subtype/object types. Note that this is a complete rewrite,
getting rid of the very nasty quadratic algorithm previously
used for derived type output.
* lib-xref.ads: Extend description of <..> notation to cover
subtype/object types. Uses {..} for these other cases.
Also use (..) for pointer types.
* sem_util.adb (Check_Potentially_Blocking_Operation): Slight cleanup.
* exp_pakd.adb: Minor reformatting. Note that prevous RH should say:
(Known_Aligned_Enough): Replaces Must_Be_Aligned.

* gnatcmd.adb:
Changed /COMPILE_ONLY to /ACTIONS=COMPILE
Changed /BIND_ONLY to /ACTIONS=BIND
Changed /LINK_ONLY to /ACTIONS=LINK
* sem_ch8.adb (Find_Selected_Component): improved search for a
candidate package in case of error.
* sem_ch12.adb (Inline_Instance_Body): place head of use_clause
chain back on scope stack before reinstalling use clauses.
* exp_ch5.adb (Expand_N_If_Statement): if Constant_Condition_Warnings
is enabled, do not kill the code for the condition, to preserve
warning.
From-SVN: r47895
* checks.adb (Insert_Valid_Check): Apply validity check to expression
of conversion, not to result of conversion.
* sem_ch3.adb (Build_Derived_Record_Type): set Controlled flag
before freezing parent. If the declarations are mutually recursive,
an access to the current record type may be frozen before the
derivation is complete.
