https://gcc.gnu.org/bugzilla/show_bug.cgi?id=98013 --- Comment #1 from CVS Commits --- The master branch has been updated by Tobias Burnus : https://gcc.gnu.org/g:f4e7ea81d1369d4d6cb6d8e440aefb3407142e05 commit r11-5571-gf4e7ea81d1369d4d6cb6d8e440aefb3407142e05 Author: Tobias Burnus Date:

[Patch, committed] Fortran's dump-parse-tree.c: Use '==' not '=' for '.eq.'.

I was a bit confused by the '=' (assignment?) in the dump; hence, in line with /=, >= etc. it now is '==' for '==' or '.eq.'. Committed as r11-5570-g2610c786f7496c5006bb68d6801ef7450bd231a9 Tobias - Mentor Graphics (Deutschland) GmbH, Arnulfstraße 201, 80634 München / Germany

[Ada] Remove all ^L characters

These control characters are mainly causing confusion at this stage, so remove them. Tested on x86_64-pc-linux-gnu, committed on trunk gcc/ada/ * gcc-interface/Makefile.in, gcc-interface/trans.c: Remove ^L characters.diff --git a/gcc/ada/gcc-interface/Makefile.in

[Ada] Wrong replacement of Component.Discriminant

The procedure Replace_Discr_Ref added a few years ago is overzealous and triggers in too many cases in the case of multiple records with discriminants involved. It appears that this procedure is no longer needed at this stage, so simply remove it. Tested on x86_64-pc-linux-gnu, committed on trunk

[Ada] Fix internal error on extended return and fixed-point result

This prevents the expander from creating an access before elaboration issue for a temporary generated for a range check applied to the expression of a degenerate extended return statement (an extended return statement without an explicit do/end construct). Expand_N_Extended_Return_Statement has

[Ada] Implement inheritance for Default_Initial_Condition and address other gaps

The existing (SPARK-based) implementation of Default_Initial_Condition aspects only applies DIC checks based on a type's own DIC (or only one DIC from an ancestor if the type doesn't specify one, but not from further up the ancestor chain), but Ada 202x (AI12-0265) specifies that all DICs of

[Ada] Expand integer-only implementation of ordinary fixed-point types

This change relaxes the conditions under which the implementation of ordinary fixed-point types uses only underlying integer instructions. These conditions are on the Small of the ordinary fixed-point types, which must now be a rational number whose factors are of a magnitude bounded relatively

[Ada] Enable checks on runtime by default

These checks are not very costly these days and bring additional safety and security guarantees built into the Ada language, so enable them by default. It turns out that enabling checks on s-bitfie.adb makes a latent visibility bug appeared on strict alignment platform (related to alignment

[Ada] Reimplement Ada.Numerics.Big_Numbers.Big_Reals.Fixed_Conversions

This reimplements the aforementioned generic package according to the requirements of the Ada 2020 RM, namely that To_Big_Real be exact and that From_Big_Real use the common conversion rules. Tested on x86_64-pc-linux-gnu, committed on trunk gcc/ada/ * libgnat/a-nbnbre.adb

[Ada] Implement -gnateb switch

The -gnateb switch instructs gnat to store configuration pragma files by their basename in ALI files instead of using absolute paths. Tested on x86_64-pc-linux-gnu, committed on trunk gcc/ada/ * doc/gnat_ugn/building_executable_programs_with_gnat.rst: Describe -gnateb switch.

[Ada] Add stream-oriented attributes support for 128-bit integer types

This was overlooked in the original implementation of these types. Tested on x86_64-pc-linux-gnu, committed on trunk gcc/ada/ * doc/gnat_ugn/building_executable_programs_with_gnat.rst (-xdr): Document that XDR is not supported for 128-bit integer types. * gnat_ugn.texi:

[Ada] Compiler crash on limited conditional expressions

This patch fixes a bug in which if the expression of an expression function is a conditional expression of limited type, the compiler crashes. Tested on x86_64-pc-linux-gnu, committed on trunk gcc/ada/ * exp_ch3.adb (Expand_N_Object_Declaration): Avoid crash in case of

[Ada] Improve error recovery

Function P_Formal_Part was unnecessarily calling Scan after calling T_Semicolon: T_Semicolon is already calling Scan to go past the comma-used-insted-of-semicolon. This avoids spurious cascaded errors in case of e.g: procedure P (A : Integer, B : Integer, C : Integer) is where ',' is used

[Ada] Fix folding of comparison operators in GNATprove mode

Folding of comparison operators was disabled for GNATprove in assertion expressions (except for some special cases). However, folding itself is harmless. The problem was only in the current value optimizer, which interferes with assertions that act as cut points for proof. Tested on

[Ada] Fix serial port control setting on GNU/Linux

This fixes an issue when setting the control flags of the serial communication port. The c_cflag termios field should not be set with the baud rate. The speed of the communication is set using the c_ispeed and c_ospeed fields. Setting the baud rate into the c_cflag has unexpected results as it

[Ada] Spurious error on iterator over container with modified private part

The compiler rejects an element iterator (for .. of) over a container that extends a predefined container with additional operations in the private part, when these added operations overload existing GNAT-specific private operations used to optimize such loops. Tested on x86_64-pc-linux-gnu,

[Ada] Potential read of uninitialized variable in exp_dist.adb

Found by using -gnatVa and Initialize_Scalars on GNAT sources. Tested on x86_64-pc-linux-gnu, committed on trunk gcc/ada/ * exp_dist.adb (RCI_Cache): Initialize.diff --git a/gcc/ada/exp_dist.adb b/gcc/ada/exp_dist.adb --- a/gcc/ada/exp_dist.adb +++ b/gcc/ada/exp_dist.adb @@ -902,7

[Ada] Crash on ghost assignment check for illegal code

This patch fixes a bug, where an assignment of the form X(Y).Z := ... causes the compiler to crash when X does not refer to a visible declaration. Tested on x86_64-pc-linux-gnu, committed on trunk gcc/ada/ * errout.adb (Error_Msg_NEL): Do not call Set_Posted if errors are being

[Ada] Small cleanup in System.Value_F

This removes a superflous processing during the conversion to fixed point. Tested on x86_64-pc-linux-gnu, committed on trunk gcc/ada/ * libgnat/s-valuef.adb (Integer_To_Fixed): Do not modify numerator or denominator in order to reduce the exponent.diff --git

[Ada] Spurious visibility error in subprogram body in with_clause

Compiler rejects a use of a name in a subprogram body that appears in a with_clause, when the name is that of an inherited function for a local derived type, and is hidden by an explicit declaration of a non-overloadable homonym, and other homonyms exist in the environment of the subprogram body.

[Ada] Add continuation message when others choice not allowed

In a context where the bounds of an array aggregate are not known, the aggregate is not allowed to include an "others" choice. The error message given by GNAT now includes a suggestion to qualify the aggregate with a constrained subtype to fix the issue. Tested on x86_64-pc-linux-gnu, committed

[Ada] Confusion in Transform_Function_Array and internal subprograms

Generating an internal subprogram (e.g. array comparison functions) returning an array, the Transform_Function_Array mechanism gets confused and references the wrong entities in some cases. Fix this discrepency by directly transforming these functions into procedures instead of triggering the

[PATCH] c++, debug: Treat -std=c++20 -gdwarf-5 like C++14 rather than C++98

Hi! I have noticed that while we use DW_LANG_C_plus_plus_14 for -std=c++17 -gdwarf-5, we use DW_LANG_C_plus_plus (aka C++98) for -std=c++20 -gdwarf-5. The following patch makes those two match. Ok for trunk if it passes bootstrap/regtest? 2020-11-30 Jakub Jelinek * dwarf2out.c
