2022-03-01perf: Add irq and exception return branch typesAnshuman Khandual1-1/+3
This expands generic branch type classification by adding two more entries there in i.e irq and exception return. Also updates the x86 implementation to process X86_BR_IRET and X86_BR_IRQ records as appropriate. This changes branch types reported to user space on x86 platform but it should not be a problem. The possible scenarios and impacts are enumerated here.

2019-09-20perf tools: Remove util.h from where it is not neededArnaldo Carvalho de Melo1-1/+0
Check that it is not needed and remove, fixing up some fallout for places where it was only serving to get something else.

2019-09-20perf tools: Remove debug.h from places where it is not neededArnaldo Carvalho de Melo1-1/+0
Pruning a bit more the includes dependency tree. Building this thing on lots of containers takes time, we better reduce the time per build, each container is doing 6 builds when clang and clang-devel are available, and the plan is to do a 'make -C tools/perf build-test' that have many more. Also helps when doing normal development, as touching some random file will have a much reduced chance of triggering lots of rebuilds.

2019-09-01perf symbols: Move mem_info and branch_info out of symbol.hArnaldo Carvalho de Melo1-0/+1
The mem_info struct goes to mem-events.h and branch_info goes to branch.h, where they belong, this way we can remove several headers from symbols.h and trim the include dependency tree more.

2019-09-01perf debug: Remove needless include directives from debug.hArnaldo Carvalho de Melo1-0/+1
All we need there is a forward declaration for 'union perf_event', so remove it from there and add missing header directives in places using things from this indirect include.

2019-08-29perf tools: Remove perf.h from source files not needing itArnaldo Carvalho de Melo1-1/+0
With the movement of lots of stuff out of perf.h to other headers we ended up not needing it in lots of places, remove it from those places.

2017-07-19perf util: Create branch.c/.h for common branch functionsJin Yao1-0/+147
Create new util/branch.c and util/branch.h to contain the common branch functions. Such as: branch_type_count(): Count the numbers of branch types branch_type_name() : Return the name of branch type branch_type_stat_display(): Display branch type statistics info branch_type_str(): Construct the branch type string. The branch type is saved in branch_flags. Change log: v8: Change PERF_BR_NONE to PERF_BR_UNKNOWN. v7: Since the common branch type name is changed (e.g. JCC->COND), this patch is performed the modification accordingly. v6: Move that multiline conditional code inside {} brackets. Move branch_type_stat_display() from builtin-report.c to branch.c. Move branch_type_str() from callchain.c to branch.c. v5: It's a new patch in v5 patch series.
