Hi Ramana, Ulrich. Could I have some help with an unexpected testsuite failure while backporting Carrot's adddi patch? testsuite/gcc.misc-tests/gcov-7.c builds and runs but aborts during leave() due to unexpected results.
The merge request is here: https://code.launchpad.net/~michaelh1/gcc-linaro/core-adddi/+merge/113111 The testsuite diff is here: http://ex.seabright.co.nz/build/gcc-linaro-4.7+bzr115001~michaelh1~core-adddi/logs/armv7l-natty-cbuild341-tcpanda06-cortexa9r1/testsuite-diff.txt The build tree is at: cbuild@tcpanda02.v:/scratch/cbuild/slave/slaves/tcpanda02/gcc-linaro-4.7+bzr115001~michaelh1~core-adddi/gcc/default/build The failing and working versions are on tcpanda02 as ~/gcov-7.exe and ~/gcov-7-ok. Here's the details: * The test is fine when built from the command line * The test is fine on the hard float Precise build * The failing binary works fine when run on Precise * The disassembled body (not libraries) is identical modulo changes in addresses * The fault goes away with a static linking via adding "--tool_opts '-static'" * The fault persists with binutils 2.22 * The fault persists with the eglibc 2.15 loader I assume the testsuite picks up a different libgcc and libgcov somehow which gives a different executable. It's strange that the static linked version is fine, and that the failing binary works fine on a different host. Could you have a poke in the build tree? -- Michael _______________________________________________ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-toolchain
