[Ada] Spurious error on universal access equality operator · 4dd8320f

2019-12-12  Ed Schonberg  <schonberg@adacore.com>

gcc/ada/

	* sem_type.adb (Find_Unique_Type): A call to the universal
	access equality operator requires one operand to be a universal
	access, and the other to be an access type. There is no
	requirement, as previously implied by this routine, that
	pool-specific access types were illegal in this context.

[Ada] Tighten up semantic checking for protected subprogram declarations · 97b2ffb8

	is unchanged.  The call in Matching_Entry_Or_Subprogram to
	instead passes in Type_Conformant. This corresponds to the use
	of "type conformant" in Ada RM 9.4(11.4/3).
	(New_Overloaded_Entity.Has_Matching_Entry_Or_Subprogram): Add
	new Normalized_First_Parameter_Type function to help in ignoring
	the distinction between protected and access-to-protected first
	parameters when checking prefixed-view profile matching. Replace
	computations of the type of the first parameter with calls to
	this function as appropriate.

[ARC] generate signaling FDCMPF for hard float comparisons · fbf8314b

PR 92846:
ARC gcc generates FDCMP instructions which raises Invalid operation for
signaling NaN only. This causes glibc iseqsig() primitives to fail (in
the current ongoing glibc port to ARC)

So break up the hard float compares into tw categories and for unordered
compares generate the FDCMPF instructions which raised exception for
either NaNs.

With this fix testsuite/gcc.dg/torture/pr52451.c passes for ARC.

Also no regressions for the glibc math testsuite, only 6 additional
passes for test*iseqsig
