USAGE: c++expr [-c CXX | -C | -I] [-i INCLUDE] [-l LIB] [-b STEPS] [-t TESTS] [-o FILE] [-O CXX_OPTS...] [-g 'GLOBAL CODE'] 'MAIN CODE'
|
|
OPTIONS:
|
|
-c CXX use specified c++ compiler
|
|
-C use cmake
|
|
-I integrate into ClickHouse build tree in current directory
|
|
-i INC add #include <INC>
|
|
-l LIB link against LIB (only for -I or -C)
|
|
-b STEPS_NUM make program to benchmark specified code snippet and run tests with STEPS_NUM each
|
|
-b perf-top run infinite benchmark and show perf top
|
|
-t TESTS_NUM make program to benchmark specified code snippet and run TESTS_NUM tests
|
|
-o FILE do not run, just save binary executable file
|
|
-O CXX_OPTS forward option compiler (e.g. -O "-O3 -std=c++20")
|
|
EXAMPLES:
|
|
$ c++expr -g 'int fib(int n) { return n < 2 ? n : fib(n-2) + fib(n-1); }' 'OUT(fib(10)) OUT(fib(20)) OUT(fib(30))'
|
|
fib(10) -> 55
|
|
fib(20) -> 6765
|
|
fib(30) -> 832040
|
|
$ c++expr -I -i Interpreters/Context.h 'OUT(sizeof(DB::Context))'
|
|
sizeof(DB::Context) -> 7776
|
|
$ c++expr -I -i Common/Stopwatch.h -b 10000 'Stopwatch sw;'
|
|
Steps per test: 10000
|
|
Test #0: 0.0178 us 5.61798e+07 sps
|
|
...
|
|
Test #4: 0.0179 us 5.58659e+07 sps
|
|
Average: 0.0179 us 5.58659e+07 sps
