Hi,
When running gdb.base/index-cache.exp with target board cc-with-tweaks with
CC_WITH_TWEAKS_FLAGS set to "-i", we run into:
...
FAIL: gdb.base/index-cache.exp: test_cache_enabled_miss: at least one file \
was created
FAIL: gdb.base/index-cache.exp: test_cache_enabled_miss: expected file is there
FAIL: gdb.base/index-cache.exp: test_cache_enabled_miss: check index-cache stats
FAIL: gdb.base/index-cache.exp: test_cache_enabled_hit: check index-cache stats
...
The problem is that the target board makes sure that the generated executable
contains a .gdb_index section, while the test assumes that the executable
doesn't contain this section.
Fix this by removing the .gdb_index section from the generated executable.
Tested on x86_64-linux with native and CC_WITH_TWEAKS_FLAGS=-i config.
OK for trunk?
Thanks,
- Tom
