From 9923fb345b7652b5d4beb5230ee3ea11199fe4f8 Mon Sep 17 00:00:00 2001

Subject: [PATCH 2/2] suppression: Add
"has_strict_flexible_array_data_member_conversion" property
In the past, it was common to have a "fake flex array" at the end of a
structure. Like this:
Nowadays, with improved compiler support, it's more common to use a real
flex array. As this is a common change which changes ABI representation
in a compatible way, we should have a suppression for it.
For example, if you have a change like this:
struct foo
{
int x;
int flex[1];
};
...
struct foo
{
int x;
int flex[];
};
abidiff reports:
[C] 'struct foo' changed:
type size changed from 64 to 32 (in bits)
1 data member change:
type of 'int flex[1]' changed:
type name changed from 'int[1]' to 'int[]'
array type size changed from 32 to 'unknown'
array type subrange 1 changed length from 1 to 'unknown'
With a new has_strict_flexible_array_data_member_conversion property,
users can specify a suppression which stops abidiff from emitting
this diff for any "fake" flex arrays being converted to real ones:
[suppress_type]
type_kind = struct
has_size_change = true
has_strict_flexible_array_data_member_conversion = true
* include/abg-comp-filter.h (has_strict_fam_conversion): Declare
new functions.

functions.
* include/abg-suppression.h

accessor functions.
* src/abg-comp-filter.cc (has_strict_fam_conversion): Define new

functions.
* src/abg-suppression-priv.h
(type_suppression::priv::has_strict_fam_conv_): Define new
data member.
* src/abg-suppression.cc
(type_suppression::{,set_}has_strict_fam_conversion): Define new
accessor functions.
(type_suppression::suppresses_diff): For a type suppression to
match a fake flex array conversion, either the size of the type
hasn't change or has_size_change must be true and then the type
must change from a fake flex array to a real flex array.
(read_type_suppression): Parse the new
'has_strict_flexible_array_data_member_conversion' property to
set the type_suppression::set_has_strict_fam_conversion property.
* doc/manuals/libabigail-concepts.rst: Add an entry for the new
'has_strict_flexible_array_data_member_conversion' property.
* tests/data/test-diff-suppr/test-has-strict-flexible-array-data-member-conversion-{1,2}.suppr:
Add new test suppression files.
* tests/data/test-diff-suppr/test-has-strict-flexible-array-data-member-conversion-report-{1,2}.txt:

* tests/data/test-diff-suppr/test-has-strict-flexible-array-data-member-conversion-v{0,1}.c:
Add source code for new binary test input files.
* tests/data/test-diff-suppr/test-has-strict-flexible-array-data-member-conversion-v{0,1}.o:
Add new binary test input files.
* tests/data/Makefile.am: Add the new test files to the source
distribution.

files to this test harness.
