For non-explicit group, perf report has already supported a option '--group' which can enable group output.
This patch-set will support perf annotate with the same '--group'.
For example,
perf record -e cycles,branches ./div perf annotate main --stdio --group
: Disassembly of section .text: : : 00000000004004b0 <main>: : main(): : : return i; : } : : int main(void) : { 0.00 0.00 : 4004b0: push %rbx : int i; : int flag; : volatile double x = 1212121212, y = 121212; : : s_randseed = time(0); 0.00 0.00 : 4004b1: xor %edi,%edi : srand(s_randseed); 0.00 0.00 : 4004b3: mov $0x77359400,%ebx : : return i; : } :
v3: --------- Move the comment which was on setup_forced_leader() to the new function perf_evlist_forced_leader().
Impact ------ perf evlist: Create a new function perf_evlist_forced_leader perf report: Use perf_evlist_forced_leader to support '--group'
v2: --------- Arnaldo points out that it should be done the way it is for perf report --group. v2 refers to this way and the patch is totally rewritten.
Init post: ---------- Post the patch 'perf annotate: Support multiple events without group'
Jin Yao (3): perf evlist: Create a new function perf_evlist_forced_leader perf report: Use perf_evlist_forced_leader to support '--group' perf annotate: Support '--group' option
