(timer::push_internal): ...here. New function. (timer::pop): Move bulk of implementation to... (timer::pop_internal): ...here. New function. (timer::push_client_item): New. (timer::pop_client_item): New. (timer::print_row): New function, taken from timer::print. (timer::print): Print "GCC items" header if we also have client items. Move row-printing to timer::print_row. Print any client items. (timer::get_topmost_item_name): New method.
- timevar.def (TV_JIT_ACQUIRING_MUTEX): New. (TV_JIT_CLIENT_CODE): New.
- timevar.h (timer::push_client_item): New declaration. (timer::pop_client_item): New declaration. (timer::get_topmost_item_name): New method. (timer::push_internal): New declaration.

(auto_timevar::auto_timevar): Add timer param. (auto_timevar::~auto_timevar): Use field "m_timer". (auto_timevar::m_timer): New field.
- toplev.c (initialize_rtl): Add g_timer as param when constructing auto_timevar instance. (toplev::toplev): Add "external_timer" param, and use it to initialize the "g_timer" global if non-NULL. (toplev::~toplev): If this created "g_timer", delete it.
- toplev.h (toplev::toplev): Replace "use_TV_TOTAL" bool param with "external_timer" timer *.

gcc/jit/ChangeLog:
- docs/topics/compatibility.rst (LIBGCCJIT_ABI_4): New.
- docs/topics/contexts.rst (GCC_JIT_BOOL_OPTION_DUMP_SUMMARY): We no longer show a profile.

- docs/topics/performance.rst: New file.
- docs/_build/texinfo/libgccjit.texi: Regenerate.
- jit-playback.c (gcc::jit::playback::context::compile): Add timer param when constructing the "toplev" instance. (gcc::jit::playback::context::acquire_mutex): Add timer param when constructing auto_timevar instance. (gcc::jit::playback::context::make_fake_args): If we have a timer, add "-ftime-report". (gcc::jit::playback::context::invoke_driver): Add timer param when constructing auto_timevar instance. (gcc::jit::playback::context::dlopen_built_dso): Likewise.
- jit-playback.h (gcc::jit::playback::context::get_timer): New accessor.
- jit-recording.c: Include timevar.h. (gcc::jit::recording::context::context): Initialize field "m_timer".
- jit-recording.h: Add forward declaration of class timer. (gcc::jit::recording::context::set_timer): New method. (gcc::jit::recording::context::get_timer): New method. (gcc::jit::recording::context::m_timer): New field.
- libgccjit++.h (gccjit::timer): New class. (gccjit::auto_time): New class. (gccjit::context::set_timer): New method. (gccjit::context::get_timer): New. (gccjit::timer::timer): New. (gccjit::timer::push): New. (gccjit::timer::pop): New. (timer::print): New. (timer::get_inner_timer): New. (timer::release): New. (auto_time::auto_time): New. (auto_time::~auto_time): New.
- libgccjit.c: Include timevar.h. (struct gcc_jit_timer): New. (gcc_jit_timer_new): New function. (gcc_jit_timer_release): New function. (gcc_jit_context_set_timer): New function. (gcc_jit_context_get_timer): New function. (gcc_jit_timer_push): New function. (gcc_jit_timer_pop): New function. (gcc_jit_timer_print): New function.
- libgccjit.h (LIBGCCJIT_HAVE_TIMING_API): New macro. (gcc_jit_timer): New typedef. (gcc_jit_timer_new): New function. (gcc_jit_timer_release): New function. (gcc_jit_context_set_timer): New function. (gcc_jit_context_get_timer): New function. (gcc_jit_timer_push): New function. (gcc_jit_timer_pop): New function. (gcc_jit_timer_print): New function.
- libgccjit.map (LIBGCCJIT_ABI_4): New. (gcc_jit_timer_new): New function. (gcc_jit_timer_release): New function. (gcc_jit_context_set_timer): New function. (gcc_jit_context_get_timer): New function. (gcc_jit_timer_push): New function. (gcc_jit_timer_pop): New function. (gcc_jit_timer_print): New function.

gcc/testsuite/ChangeLog:
- jit.dg/test-benchmark.c (test_jit): Add param "timer" and use it to push/pop timing items. (main): For each optimization level, create a gcc_jit_timer, and time all of the iteration within that level cumulatively.
- jit.dg/test-error-gcc_jit_timer_pop-mismatch.c: New test case.
- jit.dg/test-error-gcc_jit_timer_pop-too-many.c: New test case.
