From: Mark Doffman <mark.doffman@codethink.co.uk>
Date: Tue, 23 Jun 2015 22:59:08 +0000
Subject: [PATCH 01/23] Allow repeated compatible type specifications.
Add a check to see if a repeated type specification is compatible
with the previous specification. Only create an error on incompatible
type specifications for the same symbol.
Some fixes by Jim MacArthur <jim.macarthur@codethink.co.uk>

From: law <law@138bc75d-0d04-0410-961f-82ee72b054a4>

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 02/23] Pad character-to-int conversions with spaces instead of
zeros.
The pad character is 'undefined' or 'processor dependent' depending on which
standard you read. This makes it 0x20 which matches the Oracle Fortran
compiler. One of the tests tests this undefined behaviour, so I had to modify
it.

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.
This feature is enabled by the `-std=extra-legacy` compiler flag.
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.

Subject: [PATCH 13/23] Allow per-variable kind specification.
INTEGER*4 x*2, y*8
The per-variable sizes override the kind specified in the type.
At the moment, you can follow this with an array specification, so
INTEGER x*2(10) is OK, but not the other way round.
This feature is enabled by the `-std=extra-legacy` compiler flag.

Subject: [PATCH 15/16] Allow automatics in equivalence
If a variable with an automatic attribute appears in an
equivalence statement the storage should be allocated on
the stack.
Note: most of this patch was provided by Jeff Law <law@redhat.com>.

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

Subject: [PATCH 19/23] Add tests for AUTOMATIC keyword
These tests were written by Mark Doffman for his own implementation of
the AUTOMATIC keyword. Since then, Fritz Reese's implementation was
merged upstream so we no longer carry Mark's patches but the tests
may add some useful extra test coverage. Or they might not.

* options.c (SET_FLAG, SET_BITFLAG, SET_BITFLAG2): New macros.
(set_dec_flags): Set/unset DEC and std flags according to value.
(set_init_local_zero): New helper for -finit-local-zero flag group.
(gfc_init_options): Fix disabling of init flags, array temporaries
check, and dec flags when value is zero (from -fno-*).
