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...>
OPTIONS:
General options:
-aarch64-neon-syntax - Choose style of NEON code to emit from AArch64 backend:
=generic - Emit generic NEON assembly
=apple - Emit Apple-style NEON assembly
-amdgpu-dump-rtmd - Dump AMDGPU runtime metadata
-blacklist=<string> - Blacklist file (sanitizer blacklist format).
-color - use colored syntax highlighting (default=autodetect)
-demangle - Print demangled function name.
-filter-print-funcs=<function names> - Only print IR for functions whose name match this for all print-[before|after][-all] options
-gpsize=<uint> - Global Pointer Addressing Size. The default size is 8.
-mno-compound - Disable looking for compound instructions for Hexagon
-mno-fixup - Disable fixing up resolved relocations for Hexagon
-mno-pairing - Disable looking for duplex instructions for Hexagon
