Subject: [PATCH v1 0/2] Anonymous inner struct
Date: Tue, 19 Oct 2021 11:07:22 +0100 [thread overview]
Message-ID: <20211019100724.325570-1-douglas.raillard@arm.com> (raw)
From: Douglas Raillard <douglas.raillard@arm.com>
Add an --inner_anonymous pahole CLI option to make inner
struct/enum/union anonymous. This allows turning this:
struct foo { ... };
struct bar {
struct foo {
....
} a;
};
into this:
struct foo { ... };
struct bar {
struct /* foo */ {
....
} a;
};
This avoids any conflict between the two definitions of struct foo. The
case arises when dumping multiple types at once with -E, all depending
on a same inner struct:
struct bar {
struct foo {
....
} a;
};
struct bar2 {
struct foo {
....
} b;
};
On top of that, struct foo could already be defined in a public header
already imported in the compilation unit, leading to a redefinition
error, while another nested struct is private and would still need -E
for the type to be usable.
