2018-07-19perf tools: Move syscall number fallbacks from perf-sys.h to ↵Arnaldo Carvalho de Melo
tools/arch/x86/include/asm/ commit cec07f53c398f22576df77052c4777dc13f14962 upstream. And remove the empty tools/arch/x86/include/asm/unistd_{32,64}.h files introduced by eae7a755ee81 ("perf tools, x86: Build perf on older user-space as well"). This way we get closer to mirroring the kernel for cases where __NR_ can't be found for some include path/_GNU_SOURCE/whatever scenario.

2015-10-28perf tools: Make perf depend on libbpfWang Nan
By adding libbpf into perf's Makefile, this patch enables perf to build libbpf if libelf is found and neither NO_LIBELF nor NO_LIBBPF is set. The newly introduced code is similar to how libapi and libtraceevent are wired into Makefile.perf. MANIFEST is also updated for 'make perf-*-src-pkg'. Append make_no_libbpf to tools/perf/tests/make. The 'bpf' feature check is appended into default FEATURE_TESTS and FEATURE_DISPLAY, so perf will check the API version of bpf in /path/to/kernel/include/uapi/linux/bpf.h. Which should not fail except when we are trying to port this code to an old kernel. Error messages are also updated to notify users about the lack of BPF support in 'perf record' if libelf is missing or the BPF API check failed. tools/lib/bpf is added to TAG_FOLDERS to allow us to navigate libbpf files when working on perf using tools/perf/tags.

regs_query_register_offset() is a helper function which converts register name like "%rax" to offset of a register in 'struct pt_regs', which is required by BPF prologue generator. PERF_HAVE_ARCH_REGS_QUERY_REGISTER_OFFSET indicates an architecture supports converting name of a register to its offset in 'struct pt_regs'.

Commit: c6e5e9fbc3ea ("perf tools: Fix building error in x86_64 when dwarf unwind is on") removed the definition of IS_X86_64 but not all places using it, with the consequence that perf-read-vdsox32 would not be built anymore, and the default lib install directory was 'lib' instead of 'lib64'. Also needs to go to v3.19. Signed-off-by: H.J.

Certain feature tests fail with link errors: triton:~/tip/tools/perf/config/feature-checks> make test-libbabeltrace.bin gcc -MD -o test-libbabeltrace.bin test-libbabeltrace.c # -lbabeltrace provided by /tmp/cc6dRSqd.o: In function `main': test-libbabeltrace.c:(.text+0xf): undefined reference to `bt_ctf_stream_class_get_packet_context_type' although they should already fail with a build error due to lack of a proper prototype for the function. Due to this I first tried to find which library was missing - while it was the whole feature that was missing from the .h file already. To solve this, propagate -Wall -Werror to all testcases and remove them from testcase Makefile rules that used them explicitly.
