Status: UNCONFIRMED
Severity: normal
Priority: P3

Target Milestone: ---
I noticed that profile_estimate builds an inconsistent profile for this
testcase:
./xgcc -B . -c ~/toolchain/src/gcc/gcc/testsuite/gcc.dg/pr109417.c -O2 -S -o
/dev/null -fdump-tree-profile_estimate-blocks-details=- | grep -B 1 "Invalid
sum"
;; basic block 11, loop depth 1, count 2769690 (estimated locally, freq
1.4315), maybe hot
;; Invalid sum of incoming counts 4573944 (estimated locally, freq 2.3640),
should be 2769690 (estimated locally, freq 1.4315)
