I am not sure to have tested gdb with pie binary. I have run the test suite.
I can give my receipt to compile gdb-7.2 and have a limited number of test
failures
Compiled with (this is extracted from a makefile, not a bash script)
# -g is needed by a few tests, particulary when gdb test gdb
# -U_FORTIFY_SOURCE is needed by some tests
CFLAGS += -U_FORTIFY_SOURCE -g
./configure \
--build=<my target> \
--prefix=/usr \
--disable-nls \
--disable-install-libbfd \
--disable-install-libiberty \
--disable-libada \
--disable-objc-gc \
--disable-sim \
--disable-tui \
--with-system-readline \
--with-python=no
To run the tests, I used a tweaked gcc specs file that does not harden by
default or some tests will fail. That file is from toolchain gcc pass2
adjusted to work on final stage with
sed -e 's@/$(TOOLS_DIR)$(LINKER)@$(LINKER)@g' \
-e '/\*startfile_prefix_spec:/{n;s@.*@/usr/lib/ @}' \
/$(TOOLS_DIR)/etc/gcc-unhardened.specs \
> `dirname $$(gcc --print-libgcc-file-name)`/specs
I suppressed too some tests I don't care
sed -i -e 's/gdb\.ada //' -e 's/gdb\.fortran //' \
-e 's/gdb\.java //' -e 's/gdb\.objc //' \
-e 's/gdb\.pascal //' -e 's/gdb\.python //' \
gdb/testsuite/Makefile
I run the tests with one tweak to pass base/auxv.exp test
# gdb.base/auxv.exp require -c unlimited
-cd $(DIR_APP) && \
bash -c 'ulimit -c unlimited; \
make -j 1 -k check ' &> $(DIR_TEST)/$(THISAPP)-$(STAGE_ORDER).log
# Should have less than 40 failures, philosopher error randomly vary (from
machine to machine?)
Then I remove unhardened specs file
# restore gcc default hardened behavior
rm `dirname $$(gcc --print-libgcc-file-name)`/specs
