debuginfo changes

Hi

I recently upgraded from FreeBSD 13.2 to 14.0 amd64.

I'm getting one new Valgrind regression test failure that seems to be 
related to DWARF debuginfo.

The changes are partly better, partly worse.

Here is an example from the diff

  Uninitialised byte(s) found during client check request
     at 0x........: croak (tests/varinfo5so.c:29)
-   by 0x........: bar3 (tests/varinfo5so.c:97)
     by 0x........: foo3 (tests/varinfo5so.c:110)
-   by 0x........: varinfo3_main (tests/varinfo5so.c:118)
     by 0x........: varinfo5_main (tests/varinfo5so.c:156)
     by 0x........: main (tests/varinfo5.c:5)
- Address 0x........ is on thread 1's stack
- in frame #X, created by foo3 (varinfo5so.c:101)
+ Location 0x........ is 0 bytes inside nonstatic_local_undef[8],
+ declared at varinfo5so.c:105, in frame #X of thread 1

The good bit it at the end. Valgrind has found the variable name
rather than just saying it is on the stack.

The bad bit is the missing lines in the callstack. They are due to
inline functions.

Does anyone have any information as to what might have changed between 
clang 14.0.5 and 16.0.6?

A+
