[Libunwind-devel] [PATCH 0/3] ARM testsuite fixes

[Ken Werner]

Hi there,

I started to look into the testsuite failures on ARM. The first patch creates
generic and a local variant of the ex_tables.c. This lets the DWARF_* macros
work properly and fixes a segfault in case of UNW_ARM_UNWIND_METHOD=4 and
UNW_LOCAL_ONLY. The second patch increases the alternate signal stack size of
[GL]test-bt and [GL]test-trace test cases. These used to segfault on ARM
because they hitting the stack limit. A new alternate signal stack with a size
of 8k (SIGSTKSZ) is created which is (unfortunately) not enough on ARM because
unw_cursor_t needs 16k (4byte * 4096) already. It seems quite large to me but
since this is part of the ABI the UNW_TDEP_CURSOR_LEN can't be changed without
breaking existent code. The third patch just adds tests/[GL]perf-trace to the
.gitignore file. The changes can be pulled from:
git://git.linaro.org/people/kwerner/libunwind.git

Ken Werner (3):
  Create a generic and local variant of the extbl parser.
  Increase alternate signal stack size.
  Add tests/[GL]perf-trace to the .gitignore file.
