I see the following fail in some thumb multi-lib in arm-none-linux-gnueabi,
info function jit_function^M
All functions matching regular expression "jit_function":^M
^M
Non-debugging symbols:^M
0x00000790 __real_jit_function_XXXX^M
0x0000079c __jit_function_XXXX_from_arm^M
0x0000079c jit_function_0000^M
0x00000790 __real_jit_function_XXXX^M
0x0000079c __jit_function_XXXX_from_arm^M
0x0000079c jit_function_0001^M
(gdb) FAIL: gdb.base/jit.exp: one_jit_test-2: info function jit_function
the test expects to see only jit_function_0000 and jit_function_0001
one_jit_test 2 "${hex} jit_function_0000\[\r\n\]+${hex} jit_function_0001"
Symbols with the prefix "__real_" or suffix "_from_arm" is generated
by gcc/ld for arm/thumb interworking.
This patch is to restrict the pattern from "jit_function" to
"^jit_function", the output becomes expected.
gdb/testsuite:
2014-06-06 Yao Qi <yao@codesourcery.com>
* gdb.base/jit.exp (one_jit_test): Restrict the pattern
from "jit_function" to "^jit_function".
