Bug ID: 40328
Summary: Clang -ftime-report prints some sections twice since
7.0
Product: clang
Version: 7.0
Hardware: All
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: Driver
Assignee: unassignedclangb...@nondot.org
Reporter: a...@nesnausk.org
CC: llvm-bugs@lists.llvm.org, neeil...@live.com,

Since clang 7.0.0, some sections of "-ftime-report" are printed twice in the
output. Happens on current trunk too (8.0.0 trunk 351143).
These are printed twice: "Register Allocation", "Instruction Selection and
Scheduling", "DWARF Emission", "... Pass execution timing report ..."
These are printed just once like expected: "Miscellaneous Ungrouped Timers",
"Clang front-end time report".
Repro: look at output in compiler explorer, https://godbolt.org/z/MREMFW --
selecting older Clang versions in the compiler dropdown shows that this started
happening in 7.0.
