Subject: PR28778: gcc warning tweak for sprintf precision parameter
Git-repo: git://sourceware.org/git/systemtap.git
Git-commit: b0422e9e5a539164af75cddcaeb01bceca56bf12
References: bsc#1196583
A precision=-1 sentinel value got interpreted as UINT_MAX in a
context, leading to diagnostics like:
/usr/share/systemtap/runtime/vsprintf.c:341:23: error: 'strnlen' specified bound 4294967295 may exceed maximum object size 2147483647 [-Werror=stringop-overread]
Adding a clamp_t() around the parameter field to keep it limited to
STP_BUFFER_SIZE (8K by default), which is apprx. the limit for a
single printf.

On GCC12 / fedora rawhide, this diagnostic is currently generating
false positives w.r.t. a few memcpy type functions.

Subject: gcc12 c++ compatibility re-tweak for rhel6: use function pointer
instead of lambdas instead of ptr_fun<>
Git-repo: git://sourceware.org/git/systemtap.git
Git-commit: f199d1982ef8a6c6d5c06c082d057b8793bcc6aa
References: bsc#1196583
Saving 2 lines in ltrim/rtrim is probably not a good reason to drop
compatibility with the RHEL6 system compiler. Actually declaring a
named function and passing the function pointer is compatible with
everything.

Subject: gcc12 warning suppression
Git-repo: git://sourceware.org/git/systemtap.git
Git-commit: 1549784e9c71e5bf80860d314e15e6019f899de4
References: bsc#1196583
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.
