Subject: [PATCH][gdb/testsuite] xfail gdb.ada/O2_float_param.exp for aarch64 and gcc 7.5.0
Date: Wed, 7 Sep 2022 16:45:41 +0200 [thread overview]
Message-ID: <20220907144539.GA3288@delia> (raw)
Hi,
On aarch64-linux, with gcc 7.5.0, we run into:
...
(gdb) frame^M
#0 callee.increment (val=99.0, val@entry=9.18340949e-41, msg=...) at \
callee.adb:21^M
21 if Val > 200.0 then^M
(gdb) FAIL: gdb.ada/O2_float_param.exp: scenario=all: frame
...
The problem is a GCC bug, filed as "PR98148 - [AArch64] Wrong location
expression for function entry values" (
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=98148 ).
Xfail the test for aarch64 and gcc 7.
Tested on x86_64-linux and aarch64-linux.
Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=29418
Any comments?
Thanks,
- Tom
