r254152 disabled partial_reg_dependency and movx for Haswell and newer Intel processors. r258972 restored them for skylake-avx512. For Haswell, movx improves performance. But partial_reg_stall may be better than partial_reg_dependency in theory. We will investigate performance impact of partial_reg_stall vs partial_reg_dependency on Haswell for GCC 9. In the meantime, this patch restores both partial_reg_dependency and mox for Haswell in GCC 8.

Because the wide character types are neither signed integer types nor unsigned integer types they need to be transformed to an integral type of the correct size and the lowest rank (which is not necessarily the underlying type). Reuse the helpers for enumeration types to select the correct integer. The refactoring of __make_unsigned_selector and __make_signed_selector slightly reduces the number of template instantiations and so reduces memory usage.

This patch implements the rule given in R< 4.2 (11): if the component type of a string literal is a character type with a static predicate, that predicate must be applied to each character in the string.

GNAT was emitting a warning about procedures with No_Return aspect on the spec and a returning body, but failed to handle similar procedures with no explicit spec. Now fixed. This was also affecting GNATprove, where an undetected mismatch between No_Return aspect and the body was a soundness bug, i.e. GNATprove was silently accept code that raise a runtime exception. ------------ -- Source -- ------------ procedure P (X : Boolean) with No_Return is begin if X then raise Program_Error; end if; end; ----------------- -- Compilation -- ----------------- $ gcc -c p.adb p.adb:3:04: warning: implied return after this statement will raise Program_Error p.adb:3:04: warning: procedure "P" is marked as No_Return 2018-05-31 Piotr Trojanek <trojanek@adacore.com> gcc/ada/ * sem_ch6.adb (Check_Missing_Return): Handle procedures with no explicit spec.

This patch fixes a spurious copy of a limited object, when that object is a discriminated record component of a limited type LT, and the enclosing record is initialized by means of an aggregate, one of whose components is a call to a build-in-place function that returns an unconstrained object of type T. 2018-05-31 Ed Schonberg <schonberg@adacore.com> gcc/ada/ * checks.adb (Apply_Discriminant_Check): Do not apply discriminant check to a call to a build-in-place function, given that the return object is limited and cannot be copied. gcc/testsuite/ * gnat.dg/limited1.adb, gnat.dg/limited1_inner.adb, gnat.dg/limited1_inner.ads, gnat.dg/limited1_outer.adb, gnat.dg/limited1_outer.ads: New testcase.

Remove mention of unavailability, long obsolete, and reword suggestion of use to indicate that we might want to switch to an internal interface using them. The current wording suggests just that we should bind the current Sync_Compare_And_Swap Ada subprograms to __atomic_compare builtins instead of __sync_compare, which would be highly confusing. 2018-05-31 Olivier Hainque <hainque@adacore.com> gcc/ada/ * libgnat/s-atopri.ads: Update comment on __atomic_compare_exchange builtins.

This patch modifies the transient scope mechanism to create a scope when the condition of an iteration scheme returns a controlled result or involves the secondary stack. As a result, a while loop which iterates over a container properly manages the tampering bit at each iteration of the loop. 2018-05-31 Hristian Kirtchev <kirtchev@adacore.com> gcc/ada/ * exp_ch7.adb (Find_Transient_Context): An iteration scheme is a valid boudary for a transient scope. gcc/testsuite/ * gnat.dg/tampering_check1.adb, gnat.dg/tampering_check1_ivectors.ads, gnat.dg/tampering_check1_trim.adb, gnat.dg/tampering_check1_trim.ads: New testcase.

Rewriting of Max_Queue_Length expression into N_Integer_Literal should probably be done in expansion and not in analysis, but anyway it should not strip the expression from its Etype because backends (e.g. GNATprove) expect that Etype to be present. No frontend test is provided, because GNAT doesn't care about the missing Etype decoration. This patch allows to simplify AST processing in GNATprove. 2018-05-31 Piotr Trojanek <trojanek@adacore.com> gcc/ada/ * sem_prag.adb (Analyze_Pragma): Set Etype on the rewritten Max_Queue_Length expression.

Loop (in)variants should appear next to each other, which is checked by GNAT frontend. As statements inserted during expansion may break this contiguity, GNAT recognizes specially such statements which originate in loop pragmas.
