The fix for golang/go#11541 made the assertion that getting an invalid
Numeric_constant after evaluating an invalid constant must result in
an error in a binary expression. However, a Numeric_constant can be
invalid if it is unset, which occurs when either operand cannot be
converted to the right type. These errors are issued after the
Numeric_constant is lowered.
Fixesgolang/go#12615.

This patch removes the gas configure option:
--enable-compressed-debug-sections
and adds a toplevel configure option:
--enable-compressed-debug-sections={all,gas,gold,ld}
to enable compressed debug sections for gas, gold or ld by default. At
the moment, this configure option is ignored by gold and ld. For x86
Linux targets, default to compressing debug sections in gas.

-miamcu specifies how parameters are passed to functions and how value
is returned from a function. Inside function, we can use instructions
supported by -march=XXX. -miamcu -march=haswell can generate x87, SSE
and AVX instructions as long as the IA MCU psABI is followed. But since
Lakemont processor doesn't support x87 instructions, we shouldn't
generate x87 instructions with -march=lakemont. This patch separates
code generation from -miamcu and makes -march=lakemont not to generate
x87 instructions.

* par_sco.adb: Minor style fixes.
2015-10-20 Vincent Celier <celier@adacore.com>
* debug.adb: Update documentation of -gnatdu.
From-SVN: r229048
* aspects.adb Add aspect Volatile_Function to table
Canonical_Aspect.
* aspect.ads Add aspect Volatile_Function to tables
Aspect_Argument, Aspect_Delay, Aspect_Id, Aspect_Names
and Implementation_Defined_Aspect. Aspects Async_Readers,
Async_Writers, Effective_Reads and Effective_Writes are no
longer Boolean.
* einfo.adb (Get_Pragma): Add an entry for pragma
Volatile_Function.
* par-prag.adb (Prag): Pragma Volatile_Function does not need
special processing by the parser.
* rtsfind.ads Add an entry for Ada.Synchronous_Task_Control in
table RTU_Id. Add an entry for Suspension_Object in table RE_Id.
* sem_ch3.adb Fix SPARK RM references.
(Analyze_Object_Contract): Update the error guard.
* sem_ch5.adb Fix SPARK RM references.
* sem_ch6.adb (Analyze_Subprogram_Body_Contract): Ensure
that a non-volatile function does not contain an effectively
volatile parameter.
(Analyze_Subprogram_Contract): Ensure
that a non-volatile function does not contain an effectively
volatile parameter.
* sem_ch12.adb (Instantiate_Object): Remove the reference to
the SPARK RM from the error message.
* sem_ch13.adb (Analyze_Aspect_Specifications): Add
processing for aspects Async_Readers, Async_Writers,
Effective_Reads, Effective_Writes and Volatile_Function.
(Check_Aspect_At_Freeze_Point): Aspects Async_Readers,
Async_Writers, Effective_Reads, Effective_Writes and
Volatile_Function do not need special processing at the freeze
point.
* sem_prag.adb Add an entry for pragma Volatile_Function in
table Sig_Flags.
(Analyze_External_Property_In_Decl_Part):
Reimplemented as Async_Readers, Async_Writers, Effective_Reads
and Effective_Writes are no longer Boolean pragmas.
(Analyze_Global_Item): An external state or effectively
volatile object cannot appear as an item in pragma
[Refined_]Global.
(Analyze_Pragma): Change the implementation
of Async_Readers, Async_Writers, Effective_Reads and
Effective_Writes as these are no longer Boolean pragmas.
Use routine Check_Static_Boolean_Expression to verify the
optional Boolean expression of Async_Readers, Async_Writers,
Constant_After_Elaboration, Effective_Reads, Effective_Writes,
Extensions_Visible and Volatile_Function. Add processing for
pragma Volatile_Function.
(Check_Static_Boolean_Expression): New routine.
(Find_Related_Context): Update the comment on usage.
(Is_Enabled_Pragma): New routine.
* sem_prag.ads (Is_Enabled_Pragma): New routine.
* sem_res.adb Fix SPARK RM references.
(Is_OK_Volatile_Context): Add detection for return statements.
(Resolve_Actuals): Remove the check concerning an effectively volatile
OUT actual parameter as this is now done by the SPARK flow analyzer.
(Resolve_Entity_Name): Remove the check concerning an effectively
volatile OUT formal parameter as this is now done by the SPARK
flow analyzer. (Within_Volatile_Function): New routine.
* sem_util.adb (Add_Contract_Item): Add processing for pragma
Volatile_Function.
(Check_Nonvolatile_Function_Profile): New routine.
(Is_Descendant_Of_Suspension_Object): New routine.
(Is_Effectively_Volatile): Protected types and descendants of
Suspension_Object are now treated as effectively volatile.
(Is_Enabled): The optional Boolean expression of pragmas
Async_Readers, Async_Writers, Effective_Reads and Effective_Writes
now appears as the first argument.
(Is_Volatile_Function): New routine.
* sem_util.ads Add SPARK RM references.
(Add_Contract_Item): Update the comment on usage.
(Check_Nonvolatile_Function_Profile): New routine.
(Is_Effectively_Volatile): Update the comment on usage.
(Is_Volatile_Function): New routine.
* snames.ads-tmpl Add a predefined name and pragma id for
Volatile_Function.
