Description Tom de Vries 2022-07-27 14:09:49 UTC 
With aarch64, I run into:
...
FAIL: gdb.ada/O2_float_param.exp: scenario=all: frame
FAIL: gdb.ada/O2_float_param.exp: scenario=minimal: frame
...

In more detail, we have:
...
(gdb) frame^M
#0  callee.increment (val=99.0, val@entry=9.18340949e-41, msg=...) at /home/tdevries/gdb/binutils-gdb.git/gdb/testsuite/gdb.ada/O2_float_param/callee.adb:21^M
21            if Val > 200.0 then^M
(gdb) FAIL: gdb.ada/O2_float_param.exp: scenario=all: frame
...
while "val=val@entry=99.0" is expected.

A gcc PR was filed ( https://gcc.gnu.org/bugzilla/show_bug.cgi?id=98148 ) describing in detail why it fails.

The gdb fail should be xfailed for appropriate compiler versions / archs.

Or, alternatively, discarding the incorrect DW_AT_GNU_call_site_value in gdb.
