Subject: gcc12 warning suppression
|
||
|
|
Git-repo: git://sourceware.org/git/systemtap.git
|
||

Git-commit: 1549784e9c71e5bf80860d314e15e6019f899de4

The translator emits a pair of type declarations that alternate
|
||
|
|
between a char[] and a char*, depending on the size of strings
|
||
|
|
involved. The polymorphic client code includes pointer null-checking,
|
||
|
|
which -Waddress code rejects for the char[] case. The simplest
|
||
|
|
workaround is just to disable that particular diagnostic.
