DESCRIPTION
OVERVIEW: Sanitizer Coverage Processing Tool (sancov)
This tool can extract various coverage-related information from:
coverage-instrumented binary files, raw .sancov files and their symbolized .symcov
version. Depending on chosen action the tool expects different input files:
-print-coverage-pcs - coverage-instrumented binary files
-print-coverage - .sancov files
<other actions>
- .sancov files & corresponding binary files, .symcov files
USAGE: sancov [options] <action> <binary files...> <.sancov files...> <.symcov files...>

through when propagating sample block/edge weights through the CFG.
--skip-dead-files - Do not list dead source files in

--speculative-counter-promotion-max-exiting=<uint> - The max number of exiting blocks of
a loop to allow
speculative counter promotion
--speculative-counter-promotion-to-loop - When the option is false, if the
target block is in a loop, the promotion will be disallowed unless the promoted counter

value profiler
--x86-align-branch=<(plus separated list of types)> - Specify types of branches to align.
The branches's types are combination of jcc, fused, jmp, call, ret, indirect. jcc
indicates conditional jumps, fused indicates fused conditional jumps, jmp indicates
unconditional jumps, call indicates direct and indirect calls, ret indicates rets,
indirect indicates indirect jumps.
--x86-align-branch-boundary=<uint> - Control how the assembler should
align branches with NOP. If the boundary's size is not 0, it should be a power of 2
and no less than 32. Branches will be aligned to prevent from being across or
against the boundary of specified size. The default value 0 does not align
branches.
--x86-branches-within-32B-boundaries - Align selected instructions to
mitigate negative performance impact of Intel's micro code update for errata skx102.
May break assumptions about labels corresponding to particular instructions, and
should be used with caution.
