(branch_prob): Read back the value histograms. * rtl.c (reg_note_name): Add name for REG_VALUE_PROFILE note. * rtl.h (enum reg_note): Add REG_VALUE_PROFILE note. * value-prof.c: Add comment on reading the profile. * value-prof.h (COUNTER_FOR_HIST_TYPE, HIST_TYPE_FOR_COUNTER): New. * doc/invoke.texi (-fprofile-values): Document behavior with -fbranch-probabilities. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@69969 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/gcov-io.h | 11 +++++++++++ 1 file changed, 11 insertions(+) (limited to 'gcc/gcov-io.h') diff --git a/gcc/gcov-io.h b/gcc/gcov-io.h index fd5755fea78..59b202bc0a4 100644 --- a/gcc/gcov-io.h +++ b/gcc/gcov-io.h @@ -286,13 +286,24 @@ typedef HOST_WIDEST_INT gcov_type; #define GCOV_COUNTER_ARCS 0 /* Arc transitions. */ #define GCOV_COUNTERS_SUMMABLE 1 /* Counters which can be summaried. */ +#define GCOV_FIRST_VALUE_COUNTER 1 /* The first of counters used for value + profiling.
