Subject: Re: [GIT PULL 00/29] perf/core improvements and fixes


hm, probably one of these commits:

8a0c4c2843d3 perf tools: Fix libunwind build and feature detection for 32-bit build
28e962b9d79f perf tools: Fix 32-bit cross build
74af377bc25d perf tools: Fix non-debug build
9402802a416c perf tools: Fix test_on_exit for 32-bit build

broke the suppression of the auto-detection messages on repeat invocations 
of 'make', if all testcases pass.

'make' used to display this on repeat invocations:

 comet:~/tip/tools/perf> make
   BUILD:   Doing 'make -j12' parallel build
 comet:~/tip/tools/perf> make
   BUILD:   Doing 'make -j12' parallel build
 comet:~/tip/tools/perf> make
   BUILD:   Doing 'make -j12' parallel build

Now it displays the spammy auto-detection all the time:

comet:~/tip/tools/perf> make
  BUILD:   Doing 'make -j12' parallel build

Auto-detecting system features:
...                     backtrace: [ on  ]
...                         dwarf: [ on  ]
...                fortify-source: [ on  ]
...                         glibc: [ on  ]
...                          gtk2: [ on  ]
...                  gtk2-infobar: [ on  ]
...                      libaudit: [ on  ]
...                        libbfd: [ on  ]
...                        libelf: [ on  ]
...             libelf-getphdrnum: [ on  ]
...                   libelf-mmap: [ on  ]
...                       libnuma: [ on  ]
...                       libperl: [ on  ]
...                     libpython: [ on  ]
...             libpython-version: [ on  ]
...                      libslang: [ on  ]
...                     libunwind: [ on  ]
...                       on-exit: [ on  ]
...                stackprotector: [ on  ]
...            stackprotector-all: [ on  ]

maybe a new testcase fails on my box, but is not properly displayed?

Thanks,

	Ingo
