Subject: [PATCH v4 11/15] gdb/testsuite: Update gdb.base/so-impl-ld.exp
Date: Wed, 20 Jul 2022 16:44:37 -0300 [thread overview]
Message-ID: <20220720194441.168906-13-blarsen@redhat.com> (raw)
In-Reply-To: <20220720194441.168906-1-blarsen@redhat.com>
gdb.base/so-impl-ld.exp was setup assuming that the compiler would add
epilogue information and that GDB would stop in the } line. This would
make clang tests fail like so:
step^M
solib_main (arg=10000) at ../../../common/git-repos/binutils-gdb/gdb/testsuite/gdb.base/solib1.c:7^M
7|__ return arg*arg;|__|___/* HERE */^M
(gdb) PASS: gdb.base/so-impl-ld.exp: step into solib call
next^M
main () at ../../../common/git-repos/binutils-gdb/gdb/testsuite/gdb.base/so-impl-ld.c:22^M
22|_ return 0;^M
(gdb) FAIL: gdb.base/so-impl-ld.exp: step in solib call
next^M
0x00007ffff7cef560 in __libc_start_call_main () from /lib64/libc.so.6^M
(gdb) FAIL: gdb.base/so-impl-ld.exp: step out of solib call
This patch changes it so solib_main has 2 lines where GDB can stop
regardless of compiler weirdness, and updates the exp file to
generically deal with unknown number of steps until leaving that
function.
