From f3e3034684c7ac44a14c70d6a248d8acee303176 Mon Sep 17 00:00:00 2001
From: law <law@138bc75d-0d04-0410-961f-82ee72b054a4>
Date: Thu, 10 May 2018 11:48:34 +0100
Subject: [PATCH 01/16] Default widths for i, f and g format specifiers in
format strings.
Enabled using -fdec.
The behaviour is modelled on the Oracle Fortran compiler. At the time
of writing, the details were available at this URL:
https://docs.oracle.com/cd/E19957-01/805-4939/6j4m0vnc3/index.html#z4000743746d
Addition by Mark Eggleston <mark.eggleston@codethink.com>:
Use -fdec-format-defaults to enable this feature. Also enabled using -fdec.

Subject: [PATCH 03/16] Convert LOGICAL to INTEGER for arithmetic ops, and vice
versa
We allow converting LOGICAL types to INTEGER when doing arithmetic
operations, and converting INTEGER types to LOGICAL for use in
boolean operations.
This feature is enabled with the -flogical-as-integer flag.
Note: using this feature will disable bitwise logical operations enabled by
-fdec.

Subject: [PATCH 06/16] Allow blank format items in format strings
This has to be written in a slightly verbose manner because GCC 7
defaults to building with -Werror=implicit-fallthrough which prevents
us from just falling through to the default: case.
Test written by: Francisco Redondo Marchena <francisco.marchena@codethink.co.uk>
Use -fdec-blank-format-item to enable. Also enabled by -fdec.

Subject: [PATCH 09/16] Allow old-style initializers in derived types
This allows simple declarations in derived types and structures, such as:
LOGICAL*1 NIL /0/
Only single value expressions are allowed at the moment.
Use -fdec-old-init to enable. Also enabled by -fdec.

From 08e63b85674f146b5f242906d7d5f063b2abd31c Mon Sep 17 00:00:00 2001
From: Jim MacArthur <jim.macarthur@codethink.co.uk>
Date: Wed, 7 Oct 2015 17:04:06 -0400
Subject: [PATCH 10/16] Allow string length and kind to be specified on a per
variable basis.
This allows kind/length to be mixed with array specification in
declarations.
e.g.
INTEGER*4 x*2, y*8
CHARACTER names*20(10)
REAL v(100)*8, vv*4(50)
The per-variable size overrides the kind or length specified for the type.
Use -fdec-override-kind to enable. Also enabled by -fdec.
Note: this feature is a merger of two previously separate features.
Now accepts named constants as kind parameters:
INTEGER A
PARAMETER (A=2)
INTEGER B*(A)
Contributed by Mark Eggleston <mark.eggleston@codethink.com>
Now rejects invalid kind parameters and prints error messages:
INTEGER X*3
caused an internal compiler error.

From 9bf3b68e118a749ab87f52649fd56aca059470e8 Mon Sep 17 00:00:00 2001

Subject: [PATCH 16/16] Suppress warning with -Wno-overwrite-recursive
The message "Warning: Flag '-fno-automatic' overwrites '-frecursive'" is
output by default when -fno-automatic and -frecursive are used together.
It warns that recursion may be broken, however if all the relavent variables
in the recursive procedure have automatic attributes the warning is
unnecessary so -Wno-overwrite-recursive can be used to suppress it. This
will allow compilation when warnings are regarded as errors.
Suppress warning with -Wno-overwrite-recursive

commit 632183ddcc8f3aead8b4fc63c4ab59a42ef9ad00
Author: Jonathan Wakely <jwakely@redhat.com>
Date: Wed Jun 17 22:49:06 2020 +0100
libstdc++: Avoid stack overflow in std::vector (PR 94540)
The std::__uninitialized_default_n algorithm used by std::vector creates
an initial object as a local variable then copies that into the
destination range. If the object is too large for the stack this
crashes. We should create the first object directly into the
destination and then copy it from there.
This doesn't fix the bug for C++98, because in that case the initial
value is created as a default argument of the vector constructor i.e. in
the user's code, not inside libstdc++. We can't prevent that.
PR libstdc++/94540
* include/bits/stl_uninitialized.h (__uninitialized_default_1<true>):
Construct the first value at *__first instead of on the stack.
(__uninitialized_default_n_1<true>): Likewise.
Improve comments on several of the non-standard algorithms.

crt files and statically linked libgcc objects cause false positives
in annobin coverage, so we add the assembler flag to generate notes
for them.
The patch also adds notes to libgcc_s.so, but this is harmless because
these notes only confer that there is no other annobin markup.
