Hi,
The x86 selftests build broke upstream:
triton:~/tip/tools/testing/selftests/x86> make Makefile:44: warning: overriding recipe for target 'clean' ../lib.mk:51: warning: ignoring old recipe for target 'clean' gcc -m32 -o /single_step_syscall_32 -O2 -g -std=gnu99 -pthread -Wall single_step_syscall.c -lrt -ldl -lm /usr/bin/ld: cannot open output file /single_step_syscall_32: Permission denied collect2: error: ld returned 1 exit status Makefile:47: recipe for target '/single_step_syscall_32' failed make: *** [/single_step_syscall_32] Error 1
It used to be possible to build only the x86 testcases in that directory.
Another problem is that the pkeys testcases are still very noisy:
gcc -m64 -o /home/mingo/tip/tools/testing/selftests/x86/protection_keys_64 -O2 -g -std=gnu99 -pthread -Wall protection_keys.c -lrt -ldl In file included from protection_keys.c:45:0: pkey-helpers.h: In function ‘sigsafe_printf’: pkey-helpers.h:41:3: warning: ignoring return value of ‘write’, declared with attribute warn_unused_result [-Wunused-result] write(1, dprint_in_signal_buffer, len); ^ protection_keys.c: In function ‘dumpit’: protection_keys.c:407:3: warning: ignoring return value of ‘write’, declared with attribute warn_unused_result [-Wunused-result] write(1, buf, nr_read); ^ gcc -m64 -o /home/mingo/tip/tools/testing/selftests/x86/test_vdso_64 -O2 -g -std=gnu99 -pthread -Wall test_vdso.c -lrt -ldl test_vdso.c: In function ‘main’: test_vdso.c:98:37: warning: ‘node’ may be used uninitialized in this function [-Wmaybe-uninitialized] if (!ret_vsys && (cpu_vsys != cpu || node_vsys != node)) ^ test_vdso.c:78:12: note: ‘node’ was declared here unsigned node; ^
I thought all this got already fixed?
Thanks,
Ingo
